ISS Astronauts Face Most Dangerous Challenge Ever: Home Remodeling

Astronauts prepare to give International Space Station extreme home makeover

By Daily Mail Reporter

The International Space Station is about to get all the comforts of a modern, high-end, 'green' home: a recycling water filter, kitchen fridge, extra bedrooms and workout equipment.

Space shuttle Endeavour's seven astronauts are due to carry the extra mod cons up to the station over the weekend.

They will convert the living area from a three-bedroom, one-bath, one-kitchen home to a five-bedroom, two-bath and two-kitchen home.

Changes to the International Space Station will enable it to home six astronauts instead of just three

NASA is already environmentally friendly, generating power through solar panels and recycling most waste.

But a new water recovery system will take this one step further, turning urine and condensation into fresh drinking water.

The system is essential if NASA is to increase the size of the space station crew from three to six by the middle of next year.

Endeavour's commander, Christopher Ferguson, said the water system would make deep-space exploration easier once crews are freed of lugging water.

'I would challenge you to find any other system on the Earth that recycles urine into drinkable water. It's such a repulsive concept that nobody would even broach it,' he said.

'But that day will come on this planet, too, where we're going to need to have these technologies in place, and this is just a great way to get started.'

The astronauts are also excited about getting their first kitchen fridge on board keeping their drinks cold and fruit fresher for long. The current lone refrigerator on board is restricted to science experiments.

'It seems kind of trivial, but six months of lukewarm orange juice can kind of bum you out,' said astronaut Sandra Magnus, who will fly up on Endeavour and move in for 14 weeks.

An exercise machine capable of some 30 routines will also be delivered.

NASA does not expect to get the water generation system up and running before spring. That's how long it will take to check everything and make sure the recycled water is safe to drink. Until then, the space station crew will continue to use water delivered by the shuttle and unmanned Russian supply ships.

Before Endeavour leaves, urine already collected by space station residents will be flushed through the system and undergo distillation, so recycled water samples can be returned to Earth for analysis.

Additional samples will be brought back by another shuttle in February to make absolutely certain the system is working properly.

If everything goes well, the space station will open its doors to six full-time residents next May or June.

The jump in crew size is especially important for the Canadian, European and Japanese astronauts who have been waiting years to live aboard the space station.

The larger, more diverse crew will boost the amount time spent on scientific research from 10 hours a week - the average now - to 35 hours a week, Suffredini said.

Most of the crew's time is now devoted to upkeep, and the maintenance chores will grow as the 10-year-old space station ages, he noted.

While fixing up the inside of the space station, Endeavour's astronauts will tackle a greasy, grimy job on the outside.

Three of the crew will take turns cleaning and lubricating a jammed solar-wing rotating joint; it's clogged with metal shavings from grinding parts and hasn't worked correctly for more than a year.

HiPER Laser Fusion Project "Starts" Tomorrow, Could Save Earth

Nuclear fusion energy project could lead to limitless clean electricity


By Richard Gray, Science Correspondent
Last Updated: 12:01am BST 05/10/2008

The power of the sun is to be recreated in a new £1 billion science project which aims to provide a clean and almost limitless source of energy.

Here is how it works:

• HiPER is being designed to demonstrate the feasibility of laser driven fusion as a future energy source. It will also enable the investigation of the science of truly extreme conditions – accessing regimes which cannot be produced elsewhere on Earth (temperatures of hundreds of millions of degrees, billion atmosphere pressures, and enormous electric and magnetic fields).

• HiPER will require major developments in technology, building on the highly successful European capability in this area. In particular, the PETAL laser, located in the Aquitaine region of France, will be a fore-runner to the HiPER facility to address physics and technology issues of strategic relevance for HiPER

British scientists will this week begin work to create a nuclear fusion reactor, which will use the same powerful reactions that take place in the Sun to provide energy and, ultimately, electricity.

Scientists have previously only been able to replicate the reaction inside hydrogen bombs.

Now, however, they believe they are on the verge of achieving controlled fusion in a laboratory for the first time.

Laser beams with enough power to light up every home in Britain for a few microseconds will be used to heat up the nuclear fuel to millions of degrees centigrade in order to trigger the reaction.

If successful, the reactor will be a prototype for future commercial power stations, providing a cleaner and safer replacement for conventional nuclear power stations, which use nuclear fission to produce energy.

Unlike nuclear fission, which tears apart atoms to release energy and highly radioactive by-products, fusion involves squeezing two "heavy" hydrogen atoms, called deuterium and tritium together so they fuse, producing harmless helium and vast amounts of energy.

Previous attempts to harness fusion have failed due to the huge amount of power needed to start the reaction and keep it running, leading to more power being put into the system than is ever given out. But scientists at the Rutherford Appleton Laboratory, near Oxford, hope their approach will generate useful power for the first time.

Leading a consortium of physicists from across Europe they will tomorrow launch the three year process of planning and designing the High Powered Laser Research (HiPER) facility.

Professor Mike Dunne, director of the central laser facility at the Rutherford Appleton Laboratory and one of the scientists leading the fusion project, said that fusion could provide a safe source of energy with no carbon emissions and plentiful energy supplies.

He said: "HiPER is aiming to bridge the step between proving nuclear fusion is possible and a commercial power station.

"It should prove that a big enough laser can be built, with a high enough repetition rate and efficiency, which are the critical building blocks on the route towards fusion energy."

Fusion reactors are already under construction in the US and France using two separate approaches to creating the intense pressure and heat required to trigger the nuclear fusion reaction.

The National Ignition Facility in Livermore, California, is aiming to use powerful lasers to create the intense pressures required to trigger the reaction when it is switched on next year, but the lasers are so powerful it is likely to use up more energy than it produces, meaning the technology would be useless for a commercial power station.

A separate approach at the International Thermonuclear Experimental Reactor in Cadarache, France, is aiming to use powerful magnetic fields to spark the reaction but this is again not thought to be terribly efficient. The HiPER project will adapt the American laser approach and improve its efficiency so that it can trigger the reaction at lower pressure.

"The National Ignition Facility will prove fusion can be achieved with lasers and we are then the next step," said Professor Dunne.

"If you think of the NIF as being like a diesel engine – the lasers compress the fuel pellet until the pressure causes the fusion reaction to start.

"HiPER is more like a petrol engine where the fuel is compressed a little by the lasers but then a second more powerful laser acts like a spark plug to trigger the fusion reaction."

The researchers have received £13 million for the first phase of the £1 billion project to build the HiPER facility. Most of the funding has come from the UK government funded Science and Technology Facilities Council, together with contributions from the European Commission.

It comes at a time when the Government is facing intense opposition to its plans to build new nuclear fission power stations in order to meet rising energy demands as fossil fuel supplies begin to run low.

Unlike nuclear fission, the fusion reaction produces only produces very small amounts of low-grade radioactive material and does not carry the risk of radioactive meltdown.

Fusion fuel, deuterium and tritium is also readily available in seawater. Just 2lbs of fusion fuel is capable of producing the same amount of energy as 10,000 tonnes of fossil fuel.

A spokesman for the STFC said: "The future location of HiPER is being explored over the next few years, with the UK being a prime candidate."

Martin O'Brien, fusion programme manager at the UK Atomic Energy Authority, added: "Fusion is increasingly recognised internationally as a possible long term clean energy supply. The UK is very much in the leading position on nuclear fusion."

The Kanzius Machine

Guy Invents Potential Cancer Cure With Radio Machine Built Out of Pie Pans... and Hot Dogs


John Kanzius, a businessman and radio technician diagnosed with leukemia, came up with what some call "the most promising breakthroughs in cancer." His "radio wave machine" is discussed in the following segment from CBS' 60 Minutes:

You know, I really love it when (sorta) average guys out-innovate mega-corporate profit machines, like that homemade MRI machine. But this is more amazing: John Kanzius has no background in cancer research but might have invented a real cure. He was diagnosed with leukemia, and struck by the idea that radio waves could kill cancer cells. So he built a prototype machine using pie pans and conducted tests on hot dogs injected with copper sulfate—the radio waves only heat up metal spots, for tactical nuking without nasty side effects. It's now being tested at the University of Pittsburgh and M.D. Anderson Cancer Center, where the lead doc says that it "may allow us to treat just about any kind of cancer you can imagine."

So how to get metal bits to cancer cells? This is where the big corporate research comes in: nanotechnology. Thousands of nano-particles composed of metal bits can fit in a cancer cell. So far, they've conducted successful cancer extermination trials using the Kanzius machine and metal nano-particles at both M.D. Anderson and Pittsburgh. The catch is that it's only been tested on solid tumors—hitting cancer that's spread around the body is what they're working toward, and if they can't hunt down the individual cancer cells with the nano-particles, this will only have limited applications.

Human trials are also still four years away, which unfortunately might not be in time for the machine's inventor to cure himself. [CBS via Medgadget]

First South Korean sent into space




Yi So-Yeon said she hopes North Koreans will share her "triumph" in space [AFP]
Thousands of South Koreans have gathered across the country to celebrate the blast-off of the country's first astronaut into space.

Yi So-Yeon took off on Tuesday from the same launch pad at the Baikonur cosmodrome in Kazakhastan where Yury Gagarin, the first man in space, began his famous flight in 1961.






A biosystem engineer, Yi will conduct 14 scientific experiments while in space and has said that she hopes her flight would help further Korean science and bring peace with North Korea.

The launch made South Korea the 36th nation to send a person into orbit.









Lee Myung-Bak, the South Korean president said: "I have strong feelings today. Today will go down in history as the start date of our march towards space".

Space power

In an earlier TV interview, Lee said that South Korea is on track to become the world's seventh-largest space power in 2020, when the nation is to launch its own lunar orbiter.

"The birth of South Korea's first astronaut is celebrated by the entire nation. It will give big hope to young people, in particular."

The Soviet-made Soyuz rocket
took off from Kazakhstan [AFP]
The South Korean government paid Russia about $25 million for the right to send the first Korean into space.

Before blasting off, Yi said she was fully ready for adventure aboard the Soviet-made Soyuz TMA-12 spacecraft.

"Right now, at the ISS, inside the Soyuz and right here, I am not a woman, I'm just a cosmonaut", she said.

She also told reporters that she wanted people in North Korea to be "happy" with her 12-day mission and share in her "triumph," while voicing hope that one day the North and South would be reunited.

Yi was selected last month to be the county's first astronaut after another South Korean candidate was taken off the mission for breaching rules by taking manuals out of Russia's high-security training base.

"It's amazing! It's fantastic!," Sim Eunsup, director of the Korean Aerospace Research Institute, said as he walked away from a viewing platform.

Sim said that he hoped that Yi's flight will form the basis of the country's manned space programme.

Yi has said she planned to take kimchi, a traditional spicy cabbage, into space and sing a song to mark the anniversary of Gagarin's launch on April 12.

The Future Of Space Exploration?


Black smoke belches out of a grinding old engine as it hauls Russia's latest Soyuz space capsule across a Kazakh wasteland, while armed guards keep watch. This mixture of high and low technology is probably the future of space exploration, as resources get scarcer and more small governments and independent operators get into the space game. More images of Soyuz in the wasteland, and its launch to the International Space Station, below:

ATV Jules Verne Docks with Station

Automated Transfer VehicleThe Jules Verne, the first European Space Agency Automated Transfer Vehicle, docked to the aft port of the International Space Station's Zvezda Service Module at 10:45 a.m. EDT Thursday.

The unpiloted cargo spacecraft carries more than 7,500 pounds of equipment, supplies, water, fuel and gases for the station.

It also carries hopes and aspirations of the European Space Agency. The ATV and its advanced rendezvous system could play an important role in future space exploration.

The Jules Verne docked smoothly using its automated, laser guided rendezvous system. It was in many respects a repeat of the dry run on Monday. That practice approach brought the ATV to within 36 feet of the docking port.

The Jules Verne launched from Kourou, French Guiana, on an Ariane 5 rocket on March 9.

Solar arrays deployed as planned after two engine firings more than an hour and a half after launch. That placed the ATV in a parking orbit about 1,200 miles from the station.

It was, at almost 22 tons, the largest payload ever launched by the Ariane 5.

The Jules Verne is named after the acclaimed French science-fiction author. It is the first of perhaps seven such spacecraft to be built.

The ATV can carry about three times the cargo weight carried by the Progress, the reliable Russian unpiloted cargo carrier.

The Jules Verne initially was placed in an orbit a safe distance from the station, where a series of tests were performed. Among the last of the tests were two approaches to the station.

Those approaches ended in "escape" maneuvers, to verify a collision avoidance system. It would be used if the ATV automated docking system should fail.

The spacecraft is scheduled to remain at the station until August, for unloading and to reboost the orbiting laboratory. Subsequently it will be filled with station garbage and discards. Then it will be deorbited for destruction on re-entry over the Pacific.

Europe’s automated ship docks to the ISS



Jules Verne ATV docking


3 April 2008

ESA PR 20-2008. ATV Jules Verne, the European Space Agency’s first resupply and reboost vehicle, has successfully performed a fully automated docking with the International Space Station (ISS). This docking marks the beginning of Jules Verne’s main servicing mission to deliver cargo, propellant, water, oxygen and propulsion capacity to the Station, as well as ESA’s entry into the restricted club of the partners able to access the orbital facility by their own means.

The 19-ton unmanned spaceship manoeuvred from a holding position 39 km behind the 275-ton space outpost and conducted a 4-hour staged approach with several stops at reference points for checks. It autonomously computed its own position through relative GPS (comparison between data collected by GPS receivers both on the ATV and the ISS) and in close range it used videometers pointed at laser retroreflectors on the ISS to determine its distance and orientation relative to its target. Final approach was at a relative velocity of 7 cm/s and with an accuracy of less than 10 cm, while both the ATV and the ISS were orbiting at about 28000 km/h, some 340 km above the Eastern Mediterranean. ATV Jules Verne’s docking probe was captured by the docking cone at the aft end of Russia’s Zvezda module at 16:45 CEST (14:45 GMT). Docking was completed with hooks closing at 16:52 CEST (14:52 GMT).


First automated docking

This is the very first time in Europe that an automated docking is performed in due respect of the very tight safety constraints imposed by manned spaceflight operations. All the approach and docking phase was piloted by the ATV’s onboard computers under close monitoring by the teams of ESA, CNES (the French Space agency) and Astrium (the prime contractor) at the ATV Control Centre at CNES Toulouse, France, as well as the ISS crew inside the Zvezda module. In case of anomaly, both ends could trigger pre-programmed manoeuvres to hold position, retreat to the previous reference point or escape to a safe distance.

The ATV’s behaviour was also under surveillance from its own independent Monitoring & Safing Unit (MSU), which uses a separate set of sensors and computers to check that the approach manoeuvre is conducted safely. In case of major anomaly, the MSU would have been able to take over the commands and order a Collision Avoidance Manoeuvre (CAM) through dedicated avionics chains and thrusters.

As all operations went smoothly, none of these safety manoeuvres was required during this afternoon’s approach and docking.


Replay of Ariane 5 ES-ATV launch


Replay of Ariane 5 ES-ATV launch

The ATV Jules Verne was launched by an Ariane 5 from Europe’s spaceport in Kourou, French Guiana, on 9 March. Three days later, it successfully demonstrated its autonomous CAM capability and was cleared for ISS proximity operations. The spaceship then moved to a parking orbit for the duration of space shuttle Endeavour’s visit to the ISS. On March 29 and 31 it conducted two rehearsals of today’s docking, approaching at 11 m from the Station.


New delivery service

Now that it is docked, the ATV Jules Verne will become an additional module of the ISS for about four months. The astronauts will enter its pressurized cargo module and retrieve 1,150 kg of dry cargo, including food, clothes and equipment as well as two original manuscripts handwritten by Jules Verne and a XIXth century illustrated edition of his novel “From the Earth to the Moon”. In addition, they will pump 856 kg of propellant, 270 kg of drinking water and 21 kg of oxygen into Zvezda’s tanks.

The ATV can carry about three times as much payload as Russia’s Progress freighters but on this mission, most of it is actually propellant to be used by the ATV’s own propulsion system for periodical manoeuvres to increase the altitude of the ISS in order to compensate its natural decay caused by atmospheric drag. If required, the ATV will also be able to provide redundant attitude control to the ISS or even perform evasive manoeuvres to move the Station out of the way of potentially dangerous space debris. The first of ATV Jules Verne’s reboost manoeuvres is currently scheduled on 21 April.



ESA DG and dignitaries at ATV-CC


“The ATV is so much more than a simple delivery truck, it is an intelligent and versatile spaceship which has just demonstrated its extraordinary skills,” said Daniel Sacotte, ESA’s Director for Human Spaceflight, Microgravity and Exploration. “It is the largest and most complex spacecraft ever developed in Europe and the second in size of all the vehicle’s visiting the Station, after NASA’s space shuttle. With Columbus and the ATV, we have entered the major league of the ISS.”

“The docking of the ATV is a new and spectacular step in the demonstration of European capabilities on the international scene of space exploration ”said Jean-Jacques Dordain, ESA’s Director General. “This fantastic step is in first instance the result of collective work in Europe, including ESA Member States, industry under Astrium as prime contractor, CNES and ESA staff as well as among ISS partners, in particular the USA and Russia. We shall now reap the benefits of such investments after the launch of ESA’s Columbus laboratory, first in utilizing the unique capabilities of the ISS and secondly in preparing for the exploration of the Solar System. Now that the ATV is "up and running", I am happy to announce that in the next few weeks ESA will launch a recruitment campaign to hire new European astronauts"

2 April 2008

Jules Verne was today formally cleared to proceed with the first ISS docking attempt, scheduled for 3 April 2008 at 16:41 CEST (14:41 UT). The official go-ahead came from the International Space Station Mission Management Team (IMMT) after two flawless demonstration days in which Jules Verne proved its operational capabilities.

"We have proven that Jules Verne's systems are safe, reliable and ready to dock to the Station. Everyone has worked very hard to get to this point, and we have also proven that the team on the ground is fully ready for tomorrow's first attempt," said John Ellwood, ESA's ATV Project Manager.

The formal permission came during today's IMMT meeting held at 13:00 CEST (11:00 UT), in which ESA together with its ISS partners reviewed the Automated Transfer Vehicle's (ATV) performance from Demonstration Day 2.


Demo Day 2, held on 31 March, saw Jules Verne conduct a series of challenging manoeuvres and confirm that the spacecraft could autonomously navigate itself using optical guidance and close to station keeping point S41, just 11 m from the ISS. Jules Verne also reacted perfectly to an 'Escape' command issued by astronauts on board the ISS, proving that the vessel can automatically withdraw to a safe location when so commanded.

Tomorrow's docking attempt will see Jules Verne move past station keeping point S41 to actually dock with the Russian ISS module's docking port. Contact of the vessel's docking probe is expected at 16:41 CEST (14:41 UT), with full capture scheduled at 17:15 CEST (15:15 UT). If the docking does not occur for any reason, the next possible window occurs 48 hours later on Saturday, 5 April.

Dextre is put together on its travel pallet

The space station's new robot, Dextre, is fitted out and ready for duty.

In the third spacewalk of the latest shuttle mission, Endeavour astronauts Rick Linnehan and Robert Behnken fixed tools and cameras to the machine.

The robot, which is properly called the Special Purpose Dextrous Manipulator, will in future do much of the external work on the space station.

Dextre will now undergo a series of tests and trials before it is asked to do major tasks.

Ultimately, it will be commanded to install and remove small payloads such as electronics boxes, computers and batteries.

Linnehan and Behnken worked for six hours and 53 minutes in what was the third Extra Vehicular Activity (EVA) of the Endeavour visit.

They were unable to attach a materials science experiment to the Columbus module, but may have another opportunity later in the mission.

A fourth spacewalk will take place on Thursday. This will see astronauts test a shuttle tile repair kit and change a circuit breaker on the station.

Endeavour has already fitted the new Japanese Logistics Module brought up on this flight.

This is a storage facility for the Japan Aerospace Exploration Agency's (Jaxa) Kibo laboratory, the main section of which will travel to the station on the next shuttle mission.

The US space agency has 10 more flights planned after Endeavour to complete the space station and deliver supplies before the orbiters are retired in 2010.

Endeavour is due back on the ground on 26 March.

  • Dextre is remotely operated from inside the ISS or from the ground
  • The robot has seven joints in its arms for maximum movement
  • During operations, one arm holds onto the ISS while the other works
  • This maintains stability and ensures the arms do not hit each other
  • Dextre will install and remove small payloads such as batteries

February 29, the leap day

Happy Leap Year to every body.

Why Leap Years Are Used

This page provides the history of the leap year and the purpose it serves.

February 29, 2008

The year 2008 is a leap year. If you look at a 2008 calendar, you will see that February has five Fridays–the month begins and ends on a Friday. Between the years 1904 and 2096, leap years that share the same day of week for each date repeat only every 28 years. The most recent year in which February comprised five Fridays was in 1980, and the next occurrence will be in 2036. February 29, the leap day, has been associated with age-old traditions, superstitions and folklore.

What is a leap year?

A leap year is a year in which one extra day has been inserted, or intercalated, at the end of February. A leap year consists of 366 days, whereas other years, called common years, have 365 days.

Which years are leap years?

In the Gregorian calendar, the calendar used by most modern countries, the following three criteria determine which years will be leap years:

  1. Every year that is divisible by four is a leap year;
  2. of those years, if it can be divided by 100, it is NOT a leap year, unless
  3. the year is divisible by 400. Then it is a leap year.

According to the above criteria, that means that years 1800, 1900, 2100, 2200, 2300 and 25002000 and 2400 are leap years. are NOT leap years, while year

It is interesting to note that 2000 was somewhat special as it was the first instance when the third criterion was used in most parts of the world.

In the Julian calendar–introduced by Julius Caesar in 46 BC and patterned after the Roman calendar–there was only one rule: any year divisible by four would be a leap year. This calendar was used before the Gregorian calendar was adopted.

Why are leap years needed?

Leap years are needed to keep our calendar in alignment with the earth's revolutions around the sun.

Details

The Earth's motion around the sun
Note: The illustration is not to scale.

The vernal equinox is the time when the sun is directly above the Earth's equator, moving from the southern to the northern hemisphere.

The mean time between two successive vernal equinoxes is called a tropical year–also known as a solar year–and is about 365.2422 days long.

Using a calendar with 365 days every year would result in a loss of 0.2422 days, or almost six hours per year. After 100 years, this calendar would be more than 24 days ahead of the season (tropical year), which is not desirable or accurate. It is desirable to align the calendar with the seasons and to make any difference as insignificant as possible.

By adding a leap year approximately every fourth year, the difference between the calendar and the seasons can be reduced significantly, and the calendar will align with the seasons much more accurately.

(The term "day" is used to mean "solar day"–which is the mean time between two transits of the sun across the meridian of the observer.)

Is there a perfect calendar?

No calendars used today are perfect; they are off by seconds, minutes, hours or days every year. To make a calendar more accurate, new leap year rules have to be introduced to the Gregorian calendar, complicating the calculation of the calendar even more. It will, however, need some modifications in a few thousand years. As for the tropical year, it is approximately 365.242199 days, but varies from year to year because of the influence of other planets.

Name of calendar When introduced Average year Approximate error introduced
Gregorian calendarAD 1582365.2425 days27 seconds (1 day every 3,236 years)

365-day calendar-365 days6 hours (1 day every 4 years)
Lunar calendarancient12-13 moon-monthsvariable

A calendar similar to the Julian calendar, with every fourth year earmarked as a leap year, was first introduced by King Ptolemy III of Egypt in 238 BC.

In ancient times, it was customary to have lunar (moon) calendars, with 12 and/or 13 months every year. To align the calendar with the seasons, the 13th month was inserted as a "leap month" every two or three years. Many countries, especially in Asia still use such calendars. Read more about Leap Year in Other Calendars.

Note: Many other calendars have been and still are used throughout the world.

Why the change from the Julian to the Gregorian calendar?

The Julian calendar introduced too many leap days, thus increasing the number of days between the vernal equinox of March 21, its scheduled date as noted in AD 325 during the Council of Nicaea. The introduction of the Gregorian calendar allowed for realignment with the equinox; however, a number of days had to be dropped when the change was made. Click on any one of the year links below for a better explanation of the calendars and the days that were dropped in order to make the switch to the Gregorian calendar.

  • The Gregorian calendar was first adopted in Italy, Poland, Portugal and Spain in 1582. This was done by dropping 10 days in October of that year.
  • .In Great Britain (and America), the Gregorian calendar would not be adopted until much later, in September 1752; 11 days were dropped.
  • Sweden (and Finland) had a "double" leap year in 1712. Two days were added to February–creating a date of February 30, 1712. (This was done because the leap year in 1700 was dropped and Sweden's calendar was not synchronized with any other calendar. By adding an extra day in 1712, they were back on the Julian calendar.)

  • .The Julian calendar is currently (between the years 1901 and 2099) 13 days ahead of the Gregorian calendar (because too many leap years were added).

Other leap years facts

  • The Gregorian calendar has a 400-year cycle until it repeats the same weekdays for every year–February 29, 2008, is a Friday and February 29, 2408, is a Friday.
  • The Gregorian calendar has 97 leap years during those 400 years.
  • The longest time between two leap years is eight years. The last time that occurred was between 1896 and 1904. The next time will be between 2096 and 2104.

Latitude 48° 14 North. Longitude 174° 26 West.
Almost midnight on the North Pacific, about 230 miles south of Alaska's Aleutian Islands. A heavy fog blankets the sea. There's nothing but the wind spinning eddies through the mist.

Out of the darkness, a rumble grows. The water begins to vibrate. Suddenly, the prow of a massive ship splits the fog. Its steel hull rises seven stories above the water and stretches two football fields back into the night. A 15,683-horsepower engine roars through the holds, pushing 55,328 tons of steel. Crisp white capital letters — COUGAR ACE — spell the ship's name above the ocean froth. A deep-sea car transport, its 14 decks are packed with 4,703 new Mazdas bound for North America. Estimated cargo value: $103 million.

Joshua Davis narrates this collection of photos and Coast Guard video taken during Titan Salvage's attempt to save the Cougar Ace.

On the bridge and belowdecks, the captain and crew begin the intricate process of releasing water from the ship's ballast tanks in preparation for entry into US territorial waters. They took on the water in Japan to keep the ship steady, but US rules require that it be dumped here to prevent contaminating American marine environments. It's a tricky procedure. To maintain stability and equilibrium, the ballast tanks need to be drained of foreign water and simultaneously refilled with local water. The bridge gives the go-ahead to commence the operation, and a ship engineer uses a hydraulic-powered system to open the starboard tank valves. Water gushes out one side of the ship and pours into the ocean. It's July 23, 2006.

In the crew's quarters below the bridge, Saw "Lucky" Kyin, the ship's 41-year-old Burmese steward, rinses off in the common shower. The ship rolls underneath his feet. He's been at sea for long stretches of the past six years. In his experience, when a ship rolls to one side, it generally rolls right back the other way.

This time it doesn't. Instead, the tilt increases. For some reason, the starboard ballast tanks have failed to refill properly, and the ship has abruptly lost its balance. At the worst possible moment, a large swell hits the Cougar Ace and rolls the ship even farther to port. Objects begin to slide across the deck. They pick up momentum and crash against the port-side walls as the ship dips farther. Wedged naked in the shower stall, Kyin is confronted by an undeniable fact: The Cougar Ace is capsizing.

He lunges for a towel and staggers into the hallway as the ship's windmill-sized propeller spins out of the water. Throughout the ship, the other 22 crew members begin to lose their footing as the decks rear up. There are shouts and screams. Kyin escapes through a door into the damp night air. He's barefoot and dripping wet, and the deck is now a slick metal ramp. In an instant, he's skidding down the slope toward the Pacific. He slams into the railings and his left leg snaps, bone puncturing skin. He's now draped naked and bleeding on the railing, which has dipped to within feet of the frigid ocean. The deck towers 105 feet above him like a giant wave about to break. Kyin starts to pray.

Jackson Hole, Wyoming, 4 am.
A phone rings. Rich Habib opens his eyes and blinks in the darkness. He reaches for the phone, disturbing a pair of dogs cuddled around him. He was going to take them to the river for a swim today. Now the sound of his phone means that somewhere, somehow, a ship is going down, and he's going to have to get out of bed and go save it.

It always starts like this. Last Christmas Day, an 835-foot container vessel ran aground in Ensenada, Mexico. The phone rang, he hopped on a plane, and was soon on a Jet Ski pounding his way through the Baja surf. The ship had run aground on a beach while loaded with approximately 1,800 containers. He had to rustle up a Sikorsky Skycrane — one of the world's most powerful helicopters — to offload the cargo.

Ship captains spend their careers trying to avoid a collision or grounding like this. But for Habib, nearly every month brings a welcome disaster. While people are shouting "Abandon ship!" Habib is scrambling aboard. He's been at sea since he was 18, and now, at 51, his tanned face, square jaw, and don't-even-try-bullshitting-me stare convey a world-weary air of command. He holds an unlimited master's license, which means he's one of the select few who are qualified to pilot ships of any size, anywhere in the world. He spent his early years captaining hulking vessels that lifted other ships on board and hauled them across oceans. He helped the Navy transport a nuclear refueling facility from California to Hawaii. Now he's the senior salvage master — the guy who runs the show at sea — for Titan Salvage, a highly specialized outfit of men who race around the world saving ships.

They're a motley mix: American, British, Swedish, Panamanian. Each has a specialty — deep-sea diving, computer modeling, underwater welding, big-engine repair. And then there's Habib, the guy who regularly helicopters onto the deck of a sinking ship, greets whatever crew is left, and takes command of the stricken vessel.





The Cougar Ace

Length: 654 feet
Weight: 55,328 tons
Decks: 14
Max stowage capacity: 5,542 cars
Ballast: 11 stabilization tanks (teal)
Crew on July 23, 2006: 23

Salvage work has long been viewed as a form of legal piracy. The insurers of a disabled ship with valuable cargo will offer from 10 to 70 percent of the value of the ship and its cargo to anyone who can save it. If the salvage effort fails, they don't pay a dime. It's a risky business: As ships have gotten bigger and cargo more valuable, the expertise and resources required to mount a salvage effort have steadily increased. When a job went bad in 2004, Titan ended up with little more than the ship's bell as a souvenir. Around the company's headquarters in Fort Lauderdale, Florida, it's known as the $11.6 million bell.

But the rewards have grown as well. When the Titan team refloated that container ship in Mexico, the company was offered $30 million, and it's holding out for more. That kind of money finances staging grounds in southern Florida, England, and Singapore and pays the salaries of 45 employees who drive Lotuses, BMWs, and muscle cars tricked out with loud aftermarket DynoMax exhaust systems. There's also a wall at Titan headquarters with a row of photos of the men who died on the job. Three have been killed in the past three years.

Titan's biggest competitors are Dutch firms, which have dominated the business for at least a century due in part to the pumping expertise they developed to keep their low-lying lands dry. But 20 years ago, a couple of yacht brokers in southern Florida — David Parrot and Dick Fairbanks — got fed up dealing with crazy, rich clients and decided that saving sinking ships would be more fun. They didn't really know much about the salvage business but thought that the Dutch companies had come to rely too much on heavy machinery. When a ship was in distress, the Dutch firms invariably wanted to use their impressive fleet of tugs and heavy-lift cranes. Fairbanks envisioned a different kind of salvage company — one with no tugs or cranes of its own. Instead, the new outfit would buy jet-ready containers for pumps and generators, and when a ship called for help the Titan team would charter anything from a Learjet to a 747, fly it to the airport nearest the ship, and then hire a speedboat or a helicopter to get a team aboard. If they needed a tug, they'd rent one.

Titan's business plan hinged on the idea that ships could be saved by human ingenuity, not horsepower, and the company's unconventional approach worked. When a container ship ran aground in a remote part of Iceland in the mid-'90s, the Dutch wanted to bring in their cranes. Titan jury-rigged the ship's own 198-ton cranes and used those instead — no long-distance transport needed. In 1992, a freighter sank alongside a dock in Dunkirk, France. Again, the Dutch called for cranes, but Titan won the contract by proposing a novel approach: It hired a naval architect to create a computer model of the ship. The model indicated that the vessel would float again if water was pumped out of the holds in a specific sequence. Titan put the plan into action using a few crates of relatively inexpensive pumps; the ship bobbed to the surface as if by magic. Since then, a naval architect capable of rapidly building digital 3-D ship models has been a key member of the Titan team.

Jolted awake in Wyoming, Habib pushes himself out of bed. His dogs cluster around him. He gives Beauregard a scratch behind the ear. Clearly the dogs want to go along, but he'll need a little more help than they can give. It's time to mobilize the Titan A-team.

Seattle, Washington. Breezy, warm.
Marty Johnson zips through the traffic in his black BMW Z3 convertible. He's wearing shades, and though he just turned 40 he has a boyish look that suits the car. But the cool-guy persona has its limits. He just learned how to drive a stick shift, so he takes the long way around town to avoid hills. He is actually a shy naval architect who likes to discuss the early history of J. R. R. Tolkien's Middle-earth and certain aspects of particle physics. But he has a taste for fast cars and the money to buy them, thanks to an unusual ability to build digital models of ships.

Since graduating first in his class from New York's Webb Institute, a preeminent undergraduate naval architecture school, Johnson has traveled the world with his laptop, building 3-D models and helping refloat sunken things. He was on the team that recovered the Japanese fishing trawler sunk by a US submarine off Hawaii in 2001, and he oversaw a system to lift a submerged F-14 from 220 feet of water near San Diego in 2004. In his free time, he wins boat races in which the skippers build their vessels from scratch in six hours or less.

But so far, Johnson has refloated only vessels that are already sunk. Most days, he's cooped up in an office at the port, waiting for something exciting to happen. His skills don't go to waste — he's particularly well known for designing a 76-foot tugboat able to navigate rivers as shallow as 3 feet. But Johnson wants more; he wants to be one of those guys who drops onto the deck of a sinking ship and saves the day.

He's about to get his chance. His office calls: Rich Habib wants him on a salvage job for the history books — one Johnson might have missed if not for a lucky break. Habib's usual 3-D modeler, Phil Reed, is visiting his in-laws in Chicago, and his wife won't let him go to Alaska. He recommends Johnson, who has worked with Habib once before.

The job is daunting: Board the Cougar Ace with the team and build an on-the-fly digital replica of the ship. The car carrier has 33 tanks containing fuel, freshwater, and ballast. The amount of fluid in each tank affects the way the ship moves at sea, as does the weight and placement of the cargo. It's a complex system when the ship is upright and undamaged. When the cargo holds take on seawater or the ship rolls off-center — both of which have occurred — the vessel becomes an intricate, floating puzzle.

Johnson will have to unravel the complexity. He'll rely on ship diagrams and his own onboard measurements to re-create the vessel using an obscure maritime modeling software known as GHS — General HydroStatics. The model will allow him to simulate and test what will happen as water is transferred from tank to tank in an effort to use the weight of the liquid to roll the ship upright. If the model isn't accurate, the operation could end up sinking the ship.

Habib thinks Johnson is up to the task. In 2004 they worked together on a partially sunken passenger ferry near Sitka, Alaska. The hull was gashed open on a rock — water had flooded in everywhere. The US Coast Guard safety officer told Habib and Johnson to get off the ship, saying it was about to sink completely. It was too dangerous.

Habib refused. His point of view: It was his ship now, and he would do what he wanted. The safety officer reprimanded Habib and told him that no ship was worth "even the tip of your pinky."

Habib smiled. Insurance lawyers have calculated the value of a pinky — $14,000, tops — and that's far less than the value of a modern commercial vessel.

Johnson told the Coast Guard not to worry; the ferry would be floating again in three days at exactly 10:36 in the morning. The Coast Guard was skeptical but, three days later, as the tide peaked at 10:36 am, the ferry bobbed up and floated off the rock. It was a rush to be that right.

So when he gets the message inviting him to join the team headed to the Cougar Ace, his only question is "When do we leave?"

Trinidad and Tobago. Offshore.
And if I say to you tomorrow, take my hand child come with me. The languid sound of Led Zeppelin's "What Is and What Should Never Be" drifts across the Caribbean. A 24-foot fishing boat lolls in the blue waters, the stereo cranked up in the wheelhouse. It's to a castle I will take you, where what's to be they say will be. The island of Trinidad — lush, green, rugged — is just off the port bow. A few beers remain in the bottom of the boat's 98-can cooler, and a bottle of Guyanese rum sloshes about on the floorboards. On the back deck, a fishing pole droops lazily from the densely tattooed arm of Colin Trepte: boat owner, rum drinker, and deep-sea diver who's always ready with a roguish grin for the ladies.

Trepte loves days like this — mid-80s, a couple of snapper in the bucket, and the sun warm on his face. A sign in the wheelhouse states "This is My Ship, and I'll Do as I Damn Please." A silver skull dangles from a loop on his left ear.

Trepte's youth in the east end of London seems a long way off. The tattoos tell the story: The naked, big-breasted woman on his forearm stares at a demon etched in Puerto Rico, where a cargo ship ran aground. The dragon on his shoulder is from Iceland, where he cut a grounded freighter into pieces. Some of the designs have only been outlined — a crystal ball on his back remains deliberately empty. It represents the fact that, as a Titan salvage diver, he never knows when the phone will ring. And when it does, he could be bound for Eritrea or Tierra del Fuego, and the only real question is which bag to bring — cold weather or warm. Both are packed, waiting ashore in his bungalow outside Port of Spain on Trinidad.

His cell rings. It's Habib. Trepte sighs. All good days must come to an end.

"Cold weather or warm, mate?" Trepte asks.

North Pacific. July 25, 2006.
In the hours since the Cougar Ace rolled, the Coast Guard and Air National Guard have scrambled three helicopters from Anchorage and, in a daring rescue effort, plucked the entire 23-man crew off the ship. Nyi Nyi Tun, the ship's captain, has ordered his crew to stay mum on the cause of the accident, and Mitsui O.S.K. Lines — the ship's owners — have declined to offer a detailed explanation. Because the incident occurred in international waters, the Coast Guard has decided not to investigate any further. Only Lucky Kyin talked that night. He was whisked to an Anchorage hospital, where a reporter from the Anchorage Daily News asked him how he felt. His answer: "The whole body is pain." As to the cause of the accident, all Kyin will offer is that it interrupted his shower.

Right now, it doesn't really matter how it happened. What matters is that the Cougar Ace has become a multimillion-dollar ghost ship drifting toward the rocky shoals of the Aleutian Islands. What's worse, according to the crew, the ship is taking on water. The Coast Guard alone doesn't have the capability or expertise to handle this kind of emergency, and officials fear that the ship will sink or break up on shore. Either way, the cars would be lost, and the 176,366 gallons of fuel in the ship's tanks would threaten the area's wildlife and fishing grounds. Mazda, Mitsui, and their insurers would take a massive hit.

At first, executives at Mitsui seem to think the ship is a lost cause. They contact Titan, but then they wait for about 24 hours, apparently under the impression that the vessel will go down before anybody can save it. When they realize that it will stay afloat long enough to break up on the shore of the Aleutians, they agree to sign what's known as a Lloyd's Open Form agreement. It's a so-called no-cure, no-pay arrangement. If Titan doesn't save the ship, it doesn't get paid. But if it succeeds, its compensation is based on the value of the ship and the cargo — in this case, a still-to-be-calculated fortune.

With the deal done, Titan charters a Conquest turboprop out of Anchorage. The propellers sputter to life. The Titan crew buckles in for the three-and-a-half-hour journey to Dutch Harbor, a small fishing town about 800 miles west of Anchorage on the Aleutian chain.

But before they take off, a final member of the team hops on. It's Titan mechanic Hank Bergman, the Swedish cowboy. As a young man in a small town in Sweden, Bergman inexplicably developed an affinity for Hank Williams and fantasized about the American West. He took a job as a ship engineer to get out of Sweden and soon built a reputation as a man who could fix anything, no matter how big. He has been with Titan since its beginning; as a result, he's had the money to buy land in Durango, Colorado, stock his 864-square-foot garage with two Jeeps and a classic Mercedes-Benz 560SL, and play cowboy whenever he wants. Now he boards the small plane wearing his trademark black leather cowboy boots and says hello to everyone in his pronounced Swedish accent.

The team — Habib, Johnson, Trepte, and Bergman — arrives in Dutch Harbor and heads out to sea at top speed aboard the Makushin Bay, a 130-foot ship readied for salvage work. It's stacked with generators, steel-cutting equipment, machining tools, and salvage pumps that can remove water from the ship or transfer it from one hold to another. Johnson's laptop is loaded with GHS, and he begins building a rough model of the ship based on photographs and diagrams emailed from the owners.

After more than a day of full-speed motoring through the North Pacific, the Titan team spies the Cougar Ace. At first, it's only a sharp rise on the horizon. But as the Makushin Bay approaches, the scale of the ship dwarfs the salvage vessel. In the distance, a 378-foot Coast Guard cutter — complete with helicopter and 76-mm cannon — looks puny compared with the car carrier. It's as if the men have gone through some kind of black hole and emerged as miniatures in a new and damaged world. The Cougar Ace lies on its side, its enormous red belly exposed to the smaller boats around it. The propeller floats eerily out of the water, the rudder flopped hard to port in the air.

"Holy fuck," Trepte mutters.

Six hours later, an HH-65 Coast Guard helicopter flies the team to the ship and lowers the guys one by one onto the tilted deck in a steel basket. Dan Magone, the owner of the Makushin Bay, comes with them. He's a local salvage master himself and an expert on the region's currents, tides, weather, and shoals. He has spent more than 27 years saving fishing boats in the area and is along as an adviser to, in his words, "the big shots."

The ship is rocking, but the sea is calm, and Habib thinks it's holding steady at a list of about 60 degrees. Titan's first mission: hunt for water on board. Johnson needs to know exactly how much water is sloshing around the cargo holds so he can input the data into the digital model he's constructing.

Habib unloads coils of rope from his backpack. Descending into the sharply tilted ship will require mountaineering skills. Fortunately, Habib knows what he's doing: He once scaled a 2,300-foot frozen waterfall and recalls with fondness summiting a notoriously difficult peak in the Canadian Rockies. On the way down, he was attacked by a wolf. The faded scar makes him chuckle. Maybe the mountain adventures put things in perspective. After all, this is just a giant sideways ship floating loose in the Pacific, not a deranged wolf on his back.

The guys click their LED headlamps on. The generators have gone dead, and it'll be pitch-dark below. The ship's thick steel sidewalls block radio reception, so once the men are below they won't be able to communicate with the outside world. All they'll have is each other.

Deep within the ship, the men dangle on ropes inside an angled staircase and peer through a doorway into the number-nine cargo deck. Their lights partially illuminate hundreds of cars tilted on their side, sloping down into the darkness. Each is cinched to the deck by four white nylon straps. Periodically a large swell rolls the ship, straining the straps. A chorus of creaks echoes through the hold. Then, as the ship rolls back, the hold falls silent. It's a cold, claustrophobic nightmare slicked with trickling engine oil and transmission fluid. Trepte lowers a rope and eases into the darkness.

Everyone is wearing a harness with two carabiners attached to short straps. They've tied loops every few feet into some of their ropes, creating a series of descending handholds. Like rock climbers rappelling in slow motion, they back down the steep deck, lowering themselves one looped handhold at a time. Habib tells them to always keep one carabiner attached to a loop in the rope; that way, if they fall, the rope will save them.

They reach the middle of the deck. There's a ramp built into the side of the hull at this level — it's for driving cars on and off the ship. Now a good deal of the ramp's exterior is about 25 feet underwater. It's got a thick rubber seal, but it wasn't designed to take the pressure of submersion. Habib thinks it might be leaking.

Sure enough, as they descend farther, Trepte sees green water with a sheen of oil. The water is about 8 feet deep and runs the length of the compartment — dozens of new Mazdas can be seen beneath the murky surface like drowning victims. It means the seal has been compromised. It's leaking slowly and could fail completely at any moment. If that happened, seawater would fill the deck in a matter of minutes and drown them all. But Habib figures that since it has lasted this long, it's probably OK for now.


Navigating the Ship

Navigating the Ship
When the Titan Salvage crew first boarded the Cougar Ace, they needed to determine the extent of flooding in the holds. To get there, the men had to climb using ropes and harnesses. The mission, step-by-step:

1. Airlift to the ship on an HH-65 Coast Guard helicopter.
2. Use ropes to descend through a tilted stairwell.
3. Open the access hatch to the ninth deck and rappel past hundreds of Maxdas.
4. Survey the flooding and retrace the route back to the surface of the ship.
5. Shimmy along the top side to the rear of the ship, then climb a ladder to the back-deck opening.
6. Use ropes to descend the back desk. From the low side, jump onto a support boat.




Trepte measures the dimensions of the wedge of water in the hold using a metal weight and string and shouts out the numbers. While Johnson does some trigonometry on a small pad of paper, Habib accidentally steps on one of the straps securing a car, and the Mazda lurches downward with a screech. Trepte looks up with a start and realizes that he's at the bottom of a suspended automotive avalanche. Dozens of cars hang over his head. If one broke its straps, it would trigger a domino effect, sending a pile of Mazdas down on top of him.

"Ay, mate, try not to kill me down here, won't ya?" Trepte shouts up to Habib.

"Rog-o," echoes the response from the shadows.

Johnson finishes his calculations — the wedge of water weighs 1,026 tons, part of the weight keeping the ship pinned on its side. They will have to pump this water overboard and then fill the high-side tanks to add enough ballast to bring the ship back to an even keel. According to Johnson's preliminary computer simulations, pumping 160.9 tons into the starboard-side tanks will do the trick. But the model shows that any more than that may roll them all the way over to the other side.

"You're talking about a flop?" Habib asks.

"That's what I'm saying," Johnson replies.

The situation is more precarious than Habib had thought. If they overfill the high-side starboard tanks, the Cougar Ace will roll back to normal — but then keep going, potentially in a matter of seconds. Everybody on board would be catapulted from one side of the ship to the other, and the car straps could snap. If the cars were to pile up on one side, the added weight would create even more momentum, causing the ship to roll upside down and sink.

To avoid that, they need to pump a precise amount of water. It's Johnson's job to figure out exactly how much. In an ideal world, he would plug in data for the position and weight of all the cars and the amount of liquid in each of the ship's 33 tanks and 14 decks. Unfortunately, there's not enough time to collect all that information. He'll have to do some guessing and hope his instincts are good.



It's getting dark by the time they emerge from inside the ship — they were down for more than three hours — and Habib decides not to ask the Coast Guard to pull them off by helicopter. It would be risky in the twilight. Given the calm sea, he figures they can make their way to the back deck of the ship and jump from the low port side onto the Makushin Bay.

But when they reach the back and take stock of the situation, it doesn't seem that simple. If the deck were flat, they could just walk straight across. But now it's a 105-foot metallic cliff dotted with keg-sized steel bollards. If one of the guys were to slip when not clipped in to a rope, no amount of clawing on the hard surface would arrest his slide. He would rocket down the 60-degree incline with only the blunt steel of the bollards to break his fall.

What's worse, the automated fire-prevention system vents onto the deck. Since the generators have been down for days, the system's chilled liquid carbon dioxide is warming and expanding. Every few minutes, the oxygen-snuffing chemical explodes out of the vent in a raging, negative-110-degree cloud. Direct exposure could cause frostbite and even suffocation. Habib has tested the area with an oxygen monitor, and despite the deafening white clouds of gas that periodically explode across the deck he assures everyone that there's plenty of fresh, breathable air.

Still, the situation makes Johnson nervous. He's standing on the side of a giant winch 25 feet above the vent. He'll have to climb through the blast area to get off the ship, and his backpack is stuffed with 30 pounds of gear. It's going to be difficult to move down the looped lines with that extra, cumbersome weight.

Magone is anxious to get off the ship before nightfall makes it too difficult to jump onto the Makushin Bay. He begins to back down the deck, followed by Trepte and Bergman. The carbon dioxide explodes out of the vent, raining down slivers of dry ice. They pause to shield their faces and then keep descending.

Johnson's nervousness mounts, and he stays put. He tells Habib that his backpack is bothering him. Habib offers to climb back up to the helicopter drop zone — there's extra rope there, which he can use to lower the backpack. While Johnson twists his way out of the pack, Habib heads back up toward the drop zone.

When he reaches the lower end of the deck, Magone looks up and sees that Johnson still hasn't started his descent. "What's taking him so long," Magone wonders. "Ready for the next guy!" he shouts.

A moment passes, and suddenly Johnson is hurtling down. He blurs past Bergman, screaming. Johnson is falling, and he isn't clipped in to anything. His body ricochets off a steel stanchion, sending him into an uncontrollable spin. He plunges upside down past Trepte. Nobody has time to react — in little more than a second, he has fallen 80 feet and his head smashes into a winch, with a sickening thud. His face smacks the metal, ripping a deep laceration in his forehead. Water sloshes just below him. Blood drips into it.

"Shit, shit, shit!" Trepte shouts. He steadies himself for a moment, then radios Habib: "Marty's had a tumble."

On the top deck, Habib is coiling rope. "A tumble?" he thinks. He keeps coiling for a few seconds. A tumble's not a big deal — a tumble is like a slip and a twisted ankle. But then he realizes that a tumble for someone like Trepte could mean falling out of an airplane with no parachute. Trepte wouldn't call him unless it's serious, unless Johnson were truly injured or unconscious.

"Is he conscious?" Habib radios back, a note of rising fear in his voice.

"No," Trepte's voice squawks through the radio.

Habib hurls the rope down and races back the length of the ship. He climbs as fast as he can down the looped line through the carbon dioxide blast zone. Magone has swung over to the winch in the center of the deck and is struggling to stay in position over Johnson.

"Is he breathing?" Habib shouts.

Magone can't tell. Johnson is face down, and Magone is afraid to move him by himself. Habib swings over on a rope, and together they roll Johnson face up. His eyes are open, staring straight through Habib. No blinking. No movement. There's blood everywhere and he doesn't seem to be breathing, but he has a pulse. He's alive.

Habib's heart is racing. There's a chance. He starts mouth-to-mouth just as a boat crashes into the Cougar Ace only feet from Habib and Magone. It's the Emma Foss, a 101-foot tug whose crew, alerted by the radio exchange, has come to help. But the collision rips off a piece of the railing that's supporting Habib. He splashes into the cold water beneath the winch. In an instant, he muscles himself back up beside Johnson.

"Let's get him off," Habib shouts. He's thinking, "He can make it. He's got a pulse."

A stretcher is passed over from the Emma Foss. The men strap Johnson in and transfer him to the tug, which takes him to a Coast Guard cutter; its medical facilities can keep him alive. It's not too late.

"Come on, Marty," Habib says as they heft the litter back to the tug. "We're gonna get you out of here. Just hang in a little longer."

Johnson is hauled aboard the cutter, and the corpsmen establish a radio connection with their onshore surgeon. Coast Guard medics take over while Habib and his team jump onto the Makushin Bay and wait nervously for an hour. At 11 o'clock, the captain of the cutter calls Habib.

Marty Johnson is dead.


How Marty Johnson Fell

How Marty Johnson Fell
To get off the ship, Johnson and the others on the Titan team made their way to the back deck, then climbed down the steeply angled surface to the low side. For Johnson, it was a daunting task — he was inexperienced as a climber and carrying a pack loaded with 30 pounds of bulky gear.

1. He was standing on the starboard winch. He wasn't clipped in to his safety rope when he slipped and plummeted down the deck.
2. After 20 feet, he struck a bollard and began spinning.
3. He tumbled 60 feet more, coming to rest on the port-side winch.

Through an overcast sky, the sun dawns faintly the next morning. The Coast Guard sends a lieutenant to the Makushin Bay to find out what happened and assess the state of the team. On the surface, Trepte and Bergman seem fine. Trepte has already moved into Johnson's bunk — "he won't be needin' it," Trepte says. But a numbness seems to have gripped Habib. Maybe he should send his team home before any more lives are lost. Maybe it's time to abandon the Cougar Ace.

The lieutenant listens as Habib recounts the facts leading up to the accident: Johnson was standing on the high-side winch. Somehow he slipped and hadn't been clipped in to a rope. When Habib starts to talk about trying to save his teammate, about staring into his blank eyes, he feels a swelling in his throat. He can sense tears coming. Johnson was one of Habib's guys and was among the nation's best naval architects. Habib looks away.

What he sees isn't comforting. The Cougar Ace looms over the Makushin Bay like a rogue wave on pause. It can't be ignored — it's now 140 miles from shore, and the weather is expected to deteriorate. Winds of 26 miles per hour are expected by the next sunrise, and the weather service predicts 16-foot waves within a few days. The team has to get back on board and connect a towline to the Cougar Ace, or it will either sink or be driven ashore. The Coast Guard, the area fishermen, the ship owners, Mazda — everyone is depending on them, but they're battered, undermanned, and flying blind without Johnson. Habib makes a decision: He'll stay. But to see this job through, he needs more help. He makes a call to headquarters in Florida.

A Coast Guard ship takes Johnson's body back to Adak, a rugged Aleutian island with an airstrip. Soon, a twin-propeller plane floats down out of the sky and stops at the end of the runway. The plane's ramp flips open, and guys lugging cold-weather gear hustle down to the tarmac. They glance at the body bag and keep moving. The reinforcements have arrived.

Phil Reed — Titan's chief naval architect — got the go-ahead from his wife and leads the men. In the early '90s, Reed was one of the first to repurpose naval-architecture software for use on salvage jobs. Now 48, he's Titan's most senior 3-D modeler — a sort of geek in residence. But Reed is not a typical nerd. Sure, on almost every job he's the only guy scampering across the decks with a laptop, and he absentmindedly taps the tip of his fluorescent highlighter on his head, leaving yellow streaks across his Titan baseball cap. But he's also the guy who went into Banda Aceh after the 2004 Indian Ocean tsunami and persuaded the Indonesian military to protect the Titan team while it hauled away an upside-down 684-foot cement ship. He can take the heat as well as any guy on the team.

Two deep-sea divers — Yuri Mayani and Billy Stender — follow Reed. They look like a rough-and-tumble version of Laurel and Hardy. Mayani is a foulmouthed, hot-tempered 5'2" Panamanian with rippling muscles. Stender is a laconic 6'2" Michigan native who spends as much time as he can living in a trailer in the woods near the Canadian border. Somehow, these two have become good friends. If they're not on a job, Mayani hangs out in Michigan, cursing wildly about the cold until Stender gets enough Pabst Blue Ribbon in him. With Mayani around, Stender can sink into his natural state of bemused reticence. Anything he's thinking — whether it's about lining up the next drink or the knockers on that blonde at the end of the bar — Mayani tends to say first and five times louder. "We understand each others" is how Mayani puts it. Stender refers to his friend as "the Panamaniac."

The Sycamore, the Coast Guard ship that brought Johnson's body ashore, takes the new guys on board, and they push off for a rendezvous with the Cougar Ace. Someone from Titan headquarters in Florida calls Habib to say that Mayani, Stender, and Reed are under way. Habib hopes they'll arrive before the weather hits. The seas are already getting rougher, and that can only mean more trouble.

At 12:45 am, a fierce rain and heavy rolling ocean wakes Habib aboard the Makushin Bay. He asks the captain of the Emma Foss to use its searchlight to survey the Cougar Ace's low port-side cargo vents. Normally, these vents release car exhaust from the deep holds as vehicles are driven on and off the vessel. When the ship is upright, the vents sit about 70 feet above water and have flaps to prevent rain from entering. They were never meant to be submerged, but now the Emma Foss radios back that the high seas are churning to within 3 feet of the vents. If they go under, seawater will likely push open the flaps and surge into the ship's holds, sinking the Cougar Ace.

By noon, Habib fears he's about to lose the ship. The rapidly building swell is breaking on the port side, driving waves up to the vents. At the same time, the swell has increased the ship's roll, dipping the vents toward the waves. Habib's only hope is to tow the ship into the Bering Sea on the lee side of the Aleutians — something the Coast Guard wants him to avoid because of the potential risk to the environment. The Sea Victory — a 150-foot tug — has arrived and managed to lasso a cleat on the back of the Cougar Ace. The tug's 7,200-horsepower engine has the strength to pull the ship through the fast currents of the Samalga Pass and get to the lee side of the islands. If Habib can do that, the land will act as a shield against the wind and waves. He's got no choice. It's time to run the gauntlet.

Under low-hanging clouds, the Cougar Ace and its convoy of tugs, Coast Guard escort, and salvage craft crash through the swell in a mad dash for the Bering Sea. The Sycamore, bearing Reed, Stender, and Mayani, has gone full throttle to make this rendezvous, and the guys now stand on the deck and watch the cursed armada bear down on them.

Mayani stares at the sideways ship with disbelief. The Cougar Ace looks like a death trap to him — the crew must have been hit hard. "How many motherfuckers it died in there?" he asks.

"One," Stender says. "Our guy."

"Trick-Fuck," Mayani spits. He has a lot of respect for Habib but refers to him as "Trick-Fuck" because Habib is always tricking him into doing crazy things. And, from where Mayani is standing, this is going to be the biggest trick-fuck yet.

It's certainly one of the craziest things Reed has ever seen on the sea. He boards the Makushin Bay, and Habib grimly hands him Johnson's computer. Reed agrees with Johnson's assessment — the ship could easily flop. To decrease that risk, the team needs to make sure that the largest low-side ballast tank is filled, so it counterbalances any rapid roll. The crew had reported that they left it half full. This will be the team's first important task: a journey to the deepest part of the ship to drill a hole in the tank and fill it all the way.

To get there, they will have to descend like spelunkers. So Habib orders his men onto the Redeemer, a 132-foot tug that has joined the operation. He greets them gruffly and takes hold of a rope hanging from a railing on the Redeemer's upper deck and begins to climb using a device called an ascender. They're at the mouth of the Samalga Pass — there's no time for small talk.

Mayani looks at Stender out of the corner of his eye and asks him what's wrong with Habib: "He a fucking monkey now?"

"Shut up!" Habib shouts. He explains that the Cougar Ace has become a labyrinth. Since it's heeled onto one side, they'll have to learn how to walk on walls and scale the sloping, perilous decks. Unfortunately, they'll have to learn to do it in the middle of the ocean. This will be their only chance to practice before they board the ship. Hopefully, no one else will die.

While the team trains on the ropes, the tugs haul the Cougar Ace safely through the pass and into the calm waters of the Bering Sea. The vents ride higher above the surface — that's one less danger, for the time being. Now they need to get back aboard. The Emma Foss deposits the newly expanded team on the low side of the Cougar Ace's back deck, just a few feet from where Johnson died.

Reed serves as the navigator through the intricacies of the vessel's holds — he has spent the past 24 hours memorizing the Cougar Ace's complex design. But it's one thing to picture the orderly lines of a blueprint, quite another to traverse the dark confines of a capsized ship. As a result, Reed is not always sure where they are, and the darkness fills with a steady stream of Mayani's elaborate Spanish curses. Nobody wants to get lost inside this thing.

It takes them almost three hours of rappelling and climbing to descend to the 13th deck, and when they get there, no one is that excited to have arrived. This far down, they are well below the waterline. The Bering Sea presses in on the steel hull. They feel like they're inside an abandoned submarine.

Reed and Habib crawl along the tilted deck, periodically consulting a drawing of the ship's internal compartments. They rap their knuckles on a piece of steel — this is the top of the low-side ballast tank. Trepte pulls out a drill and bores down. Suddenly, water erupts. The tank is already full and pressurized — water must be flowing in through a broken vent on the underwater side of the ship. It sprays furiously. They have unwittingly caused the worst thing possible: The deepest cargo hold is flooding.



In an instant, Trepte covers the hole with the tip of a finger and presses hard. The sound of gushing water abruptly stops, and the shouts and curses of the moment before echo through the hold. Salt water drips off Mazdas, and the panic the men all felt transforms into a contagious laugh.

Trepte is keeping the ship afloat with one finger.

"Well, I guess the tank is already full," Reed chuckles.

"Very funny," Trepte says. "Now whyn't some of you smart chaps go figure out how to fix this bloody mess."

While Habib races to the Makushin Bay to find a solution, Mayani plugs the hole with his finger to give Trepte a break. They go back and forth for an hour and a half before Habib returns with a tapered metal bolt to jam into the hole. Their fingers took a beating, but now they know that the tank is full. Reed enters the data into his computer model, runs the numbers, and tells Habib how much water he needs to pump into the high-side tanks. It's time to roll the ship.

The plan is to position large pumps throughout the ship and begin moving liquid in a sort of orchestrated water ballet. Reed has already choreographed the dance in his GHS model but still hasn't been able to find a solution that guarantees the ship won't flip. When he runs the simulation, GHS sometimes shows the ship righting itself, but sometimes it just keeps rolling until it's belly-up. Then it sinks.


Righting the Ship

Righting the Ship
The Tital Salvage crew built a digital model of the Cougar Ace so they could develop the following plan for shifting water between ballast tanks (teal) before attempting to right the ship.

1. Position self-contained, diesel-powered pumps on the flooded ninth deck and suction it dry, dumping water overboard.
2. Check water level in the fifth port ballast tank (red) to ensure adequate counterbalance. Begin filling starboard ballast tank (yellow).
3. Fill the fifth starboard tank with 160.9 tons of seawater to bring the ship fully upright.




Habib decides not to worry about that right now and tells Mayani and Stender to position pumps near the water that has flooded into deck nine. Though they are both highly trained deep-sea divers, they play many roles on a salvage job. They can operate cranes, drive bulldozers, and slice through metal with plasma torches; Stender can even fly a helicopter. Right now, their role is to lug the 100-pound pumps into place. Since there are no functioning winches on board, the two men haul the pumps by hand, using, as Mayani likes to say, a combination of "man-draulics and the man-crane."

Mayani is assigned to play pump monkey. Stender ties one rope around his buddy, a second rope around a pump, and then, using a rock-climbing belay device, lowers both down the face of deck nine. Mayani hugs the pump so that it doesn't get banged up on the way down. What happens to Mayani is another matter.

"I'm no fucking pinball, motherfucker!" Mayani shouts as he slams against walls and cars. Stender likes the pinball reference and starts calling himself the pinball wizard.

The shouting brings Habib rappelling down. He shines his headlamp on Mayani, who — still hugging the pump — is swinging back and forth in an attempt to build up enough momentum to hop over a column of cars.

"What are you two doing?" he asks.

"What the fuck it look like we're doing?" Mayani shouts. "Stealing cars?"

"Listen, I don't want any damage," Habib says. "Not even a fingerprint."

Mayani swings away from the cars with the pump and then back, picking up more speed than he expected. He smashes into the windshield of a CX-7 and clobbers the sideview mirror of another.

"You're coming with me, bitch!" Mayani screams at the mirror and rips it clean off.

Habib shakes his head.

"Sorry!" Mayani shouts. "It was either me or the fucking mirror."

Once the pumps are set up, Stender and Mayani explore the ship. Mayani is on the hunt for some binoculars — he likes to collect mementos from jobs. He took a bright-yellow plastic radio beacon from the last ship he helped save and displays it proudly next to the flat-screen TV in his Florida condo. Sometimes the ship's crew objects, calling the guys pirates.

"What the fuck you think we are?" Mayani likes to say. "We look like yuppies?"

Luckily, the Cougar Ace is a ghost ship — there's no one to get in their way. Stender and Mayani make their way to the bridge. There are no ropes up here, so they're not clipped in to anything. They find a door on the high side of the bridge, but when Mayani jostles it, it flies open, throwing him off balance. Stender lunges for him, but Mayani falls inside and slides down the steeply inclined bridge. As he accelerates, he grasps for anything and manages to wrap an arm around the captain's chair 40 feet down, arresting his fall. Amazingly, he sees a pair of binoculars dangling from the chair.

"Are you OK?" Stender shouts, on the verge of panic.

"I found the motherfucking binoculars," Mayani responds, momentarily forgetting that he's hanging off the chair as though it were a tree sprouting off a cliff.

"Good job," Stender shouts back. "You did that real nice. Now how the hell you plan to get out of there?"

Mayani doesn't have a good answer. Stender looks around and sees a fire hose. He grabs the nozzle, lowers it down, and Mayani climbs up the hose. He took the type of fall that killed Johnson, but Mayani doesn't seem too bothered. Instead, he scrutinizes the binocs. One of the lenses is cracked.

"Shit," he says and throws them back down into the bridge.

"OK everyone," Habib says into his mic. Radios crackle across the Cougar Ace. Bergman, Trepte, Mayani, and Stender are ready to drop down into the holds and fire up the pumps. An additional four Titan guys have arrived to assist. "Let's get this ship straightened up," Habib says.

The pumps roar to life. Reed's model doesn't indicate how fast the ship will roll upright. If it's anything like the time the ship first rolled, it will be fast. It could be a dangerous roller-coaster ride.

Since the radios aren't powerful enough to reach the lower holds, Habib acts as both salvage master and radio relay, climbing halfway down into the ship so that his radio is close enough to pick up the signal of the guys up top and lower down. He follows Reed's plan and shouts orders: "Pump the wedge of water on deck nine overboard. Begin filling the fifth starboard ballast tank now." He's like the conductor of an unusual, waterlogged symphony.

Reed's calculations show that the fifth starboard ballast tank has to be about 20 percent full to bring the Cougar Ace all the way up, and as water begins to pour into the tank the ship starts to come off its 60-degree list.

"We're rolling her," Habib radios calmly.

Everyone aboard waits anxiously for the ship to flip in an instant, but the vessel rises slowly, like a stunned boxer after a heavy blow. Water cascades down its sides. It makes no sudden movements — it's as if the ship itself has been trying to figure out whether it can do this, whether it can really return to the land of the living.

As the Titan team coaxes the Cougar Ace upright, Habib ties a water bottle to one end of a rope and affixes the other end to a pipe, forming an improvised plumb line. Using some basic trig, he calculates their progress: 56.5 degrees ... 51 degrees ... 40 degrees. The Cougar Ace is coming up. Every hour it looks more and more like a normal ship.

Stender and Mayani stay on board, sleeping on cars, smoking cigarettes, and tending the pumps. For lunch, they toss one end of a line out a door that's halfway down the starboard hull. It reaches the Makushin Bay 50 feet below, and the boat's crew ties some food on the line. But when Stender and Mayani haul it up to discover a meal of boiled cabbage and popcorn, they snap. "We don't eat cabbage, you fucking fucks!" Mayani screams, hurling the cabbage at the crew. The crew dodges the fusillade of wet, steaming cabbage, and it splatters onto the decks and wheelhouse of the Makushin Bay.

As cabbage explodes out of the Cougar Ace, Habib checks his pendulum again and sees that it's still moving: 34 degrees, then 28 degrees and counting.

By the end of the second day of pumping, the Cougar Ace is upright. A few days later, the owners come aboard to reclaim the ship. What initially seemed like a lost cause is now floating freely. It did not sink. Ninety-nine percent of its cargo is intact. There was no environmental disaster.

Soon, a payment of more than $10 million is wired to Titan's account.

For more than a year, the 4,703 Cougar Ace Mazdas sit in a huge parking lot in Portland, Oregon. Then, in February 2008, the cars are loaded one by one onto an 8-foot-wide conveyor belt. It lifts them 40 feet and drops them inside a Texas Shredder, a 50-foot-tall, hulking blue-and-yellow machine that sits on a 2.5-acre concrete pad. Inside the machine, 26 hammers — weighing 1,000 pounds each — smash each car into fist-sized pieces in two seconds. The chunks are then spit out the back side. Though most of the cars appeared to be unharmed, they had spent two weeks at a 60-degree angle. Mazda can't be sure that something isn't wrong with them. Will the air bags function properly? Will the engines work flawlessly throughout the warranty period? Rather than risk lawsuits down the line, Mazda has decided to scrap the entire shipment.

Habib and the guys don't really give a damn. In the 16 months since they saved the Cougar Ace, the team has done laps around the globe. They pulled a stranded oil derrick off the world's most remote island, 1,700 miles west of South Africa. Then they wrangled a 1,000-foot container ship off a sandbar in Mexico and rescued a loaded propane tanker in the middle of a Caribbean storm.

But none of the men will forget the Cougar Ace. When Mayani does shots of Bacardi at clubs in Miami Beach, he sometimes thinks back to the first time he saw the car carrier floating sideways on the sea. It gives him a chill until the rum takes hold. For Stender, it's the same. Trepte is the only one who doesn't seem affected.

"Listen, mate, all I do is crazy shit," he says, on a cell phone from his bungalow on Trinidad. "You get used to it."

But Habib doesn't get used to it — Johnson's death still weighs on him. When Titan asks him to attend a CPR refresher course, he arrives solemnly in the hotel conference room near the Fort Lauderdale airport. The instructor lays out a few plastic dolls on the carpeted floor and asks Habib to demonstrate his technique. A couple of other Titan employees in attendance joke that the emaciated mannequins resemble some prostitutes they met on a recent job in Russia. Habib doesn't smile. He doesn't join their laughter. He kneels down beside one of the pale forms, breathes into its mouth, and tries to bring it back to life.
