Sunita set for record spacewalk
January 30, 2007 19:25 IST
Indian American astronaut Sunita Williams is all set to be the world's most experienced woman space-walker as she gets ready to undertake a 6.5-hour spacewalk from the International Space Station along with fellow astronaut Mike Lopez-Alegria.
The first of a record four spacewalks planned during the next month is scheduled to begin 0900 hours CST (2030 hours IST) on Wednesday. The other spacewalks have been planned for February 4, 8 and 22.
The three US spacewalks will rearrange the station's cooling system, bringing online new portions of the system that were activated during a shuttle mission in December 2006. The Russian spacewalk will free a stuck antenna on the ISS Progress 23 cargo craft docked to the aft end of the station, ensuring that craft can safely undock in April.
The construction of the $100 billion ISS began in 1998 following a joint venture by the United States, Japan, Russia, Canada, Japan and 11 participating nations of the European Space Agency, with Brazil and Italy as payload participants.
