The International Space Station Celebrates Its 10th Birthday

The International Space Station turns 10

This month marks the 10th anniversary of the first launched module of the International Space Station (ISS). The module Zarya was lifted into orbit on November 20th, 1998 by a Russian Proton rocket lifting off from Baikonur, Kazhakstan. In the decade since, 44 manned flights and 34 unmanned flights have carried further modules, solar arrays, support equipment, supplies and a total of 167 human beings from 15 countries to the ISS, and it still has a ways to go until it is done. Originally planned to be complete in 2003, the target date for completion is now 2011. Aside from time spent on construction, ISS crew members work on a good deal of research involving biology and physics in conditions of microgravity. If humans are ever to leave the Earth for extended periods, the ISS is designed to be the place where we will discover the best materials, procedures and safety measures to make it a reality.

In December 1998, the crew of Space Shuttle Mission STS-88 began construction of the International Space Station - Astronaut James Newman is seen here making final connections the U.S.-built Unity node to the Russian-built Zarya module. The crew carried a large-format IMAX camera from which this picture was taken. (NASA)

Backdropped against a blanket of heavy cloud cover, the Russian-built FGB, also called Zarya, approaches the Space Shuttle Endeavour and the U.S.-built Node 1, also called Unity (foreground) on December 6th, 1998. Inside Endeavour's cabin, the STS-88 crew readied the remote manipulator system (RMS) for Zarya capture as they awaited the rendezvous. (NASA) #

The Phantom Torso, seen here on May 13th, 2001 in the Destiny laboratory on the International Space Station (ISS), is designed to measure the effects of radiation on organs inside the body by using a torso that is similar to those used to train radiologists on Earth. The torso is equivalent in height and weight to an average adult male. It contains radiation detectors that will measure, in real-time, how much radiation the brain, thyroid, stomach, colon, and heart and lung area receive on a daily basis. The data will be used to determine how the body reacts to and shields its internal organs from radiation, which will be important for longer duration space flights. (NASA) #

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 state of the art gym equipment and brand new toilet will be delivered over the weekend

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.

Full Earth-Rise

KAGUYA (SELENE)
Image Taking of “Full Earth-Rise” by HDTV
April 11, 2008 (JST)

Japan Aerospace Exploration Agency (JAXA)
Japan Broadcasting Corporation (NHK)

The Japan Aerospace Exploration Agency (JAXA) and NHK (Japan Broadcasting Corporation) successfully captured a movie of the "Full Earth-Rise"*1 using the onboard High Definition Television (HDTV) of the lunar explorer "KAGUYA " (SELENE) on April 6, 2008 (Japan Standard Time, JST, all the following dates and time are JST.) The KAGUYA is currently flying in a lunar orbit at an altitude of about 100 km.

An "Earth-rise," or the rising Earth over the Moon, was first captured by the Apollo project. The Earth rising image taken by the KAGUYA on November 7, 2007, was not a full Earth-rise (i.e. not all of the globe was seen in shining blue.) It missed some part. This time, a "full Earth-rise"*1 was taken by the onboard HDTV in faraway space, some 380,000 km away from the Earth. This is the world's first successful shooting of such a Full Earth-Rise. It was also very precious because it was one of only two chances in a year for the KAGUYA to capture a Full Earth-Rise when the orbits of the Moon, the Earth, the Sun and the KAGUYA are all lined up.

The shooting was performed by the KAGUYA's onboard HDTV for space use, which was developed by NHK. The movie data was received at JAXA, then processed by NHK.

*1 The phenomenon expressed as a "Full Earth-Rise" can be seen from a satellite that travels around the Moon such as the KAGUYA (SELENE) or the Apollo manned spacecraft. The Earth is almost stationary when it is observed from the Moon, thus a Full Earth-Rise coming out from the horizon cannot be seen from the Moon.

The above still image is a cutout from the movie taken by the KAGUYA HDTV (tele camera) on April 6, 2008 (JST.)
The location on the Moon is around the South Pole on the back side at a south latitude of 83 degrees or higher. You can see the North American Continent on the image of the earth on the lower left and Pacific Ocean in the center. (The top of the image is the south of the Earth, thus the North American Continent is seen upside down.)
The image below shows the Earth rising from the Moon's horizon. It took about 40 seconds from the left image to the right.

The above figure shows the relative positions of the Sun, Earth, Moon and the KAGUYA by setting the Sun at the center viewing from the North. Black arrows indicate the KAGUYA's orbit around the Moon, and red arrows are the KAGUYA's moving direction. The green arrows show the Earth's revolving direction around the Sun. "Yaw around" is an attitude control maneuver to change the KAGUYA's moving direction by using its thruster for attitude control to face the solar array paddle toward the Sun. On April 3, we performed the yaw around, and the KAGUYA is now flying toward +X direction (forward direction,) which is 180 degrees around the original direction when the KAGUYA was launched (-X direction or backward direction.) Through the yaw around maneuver, the HDTV tele camera faces toward the moving direction.

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 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.
