> HOUSTON - This week, the crew aboard the International Space Station
> prepared for an unprecedented series of spacewalks. NASA astronauts
> Mike Lopez-Alegria and Suni Williams are scheduled to begin a
> 6.5-hour spacewalk from the station around 9 a.m. CST on Wednesday,
> Jan. 31. It will be the first of a record four spacewalks planned
> during the next month.
> Lopez-Alegria and Williams will conduct other spacewalks on Feb. 4, 8
> and 22. The first three spacewalks will originate from the station's
> Quest airlock and the astronauts will use U.S. spacesuits.
> Lopez-Alegria and cosmonaut Mikhail Tyurin will use Russian
> spacesuits for the last spacewalk and will exit the station from the
> Pirs airlock.
> The three U.S. 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 crew began the week unloading some of the more than 2.5 tons of
> food, fuel and supplies that were delivered to the station on Jan. 19
> by the ISS Progress 24 cargo craft, which included fresh produce,
> gifts from home, new clothing, spare parts, oxygen and water.
> The crew's attention quickly turned to preparations for the upcoming
> spacewalks. On Monday, the crew began working with the U.S.
> spacesuits. Batteries for the suits were charged, and the suit
> cooling systems were cleaned.
> On Tuesday, Lopez-Alegria and Williams trained using an onboard,
> laptop computer-based simulation. The training refreshed their skills
> operating the Simplified Aid for Extravehicular Activity Rescue, or
> SAFER, jetpack that is worn on spacesuits. The backpack allows
> spacewalkers to fly back to the station in the event they become
> separated from the complex.
> On Thursday, ground controllers in Houston commanded the station's
> robotic arm to maneuver into the position it will occupy for the
> start of the spacewalk. Aboard the station, the crew reviewed the
> plans for the first spacewalk.
> Lopez-Alegria and Williams continued checks of their spacesuits and
> checks of the SAFER backpacks Friday. The SAFER backpacks are
> propelled by compressed nitrogen gas, and, during the checkout, the
> harmless gas was released, depleting the nitrogen in one unit below
> the usable quantity. Two other usable SAFER backpacks remain onboard,
> however, and the loss of the third unit does not affect plans for the
> upcoming spacewalks.
> The crew took time during their work on Monday to speak with
> television host Martha Stewart. Crew members also took time to field
> questions by amateur radio from two schools, one in Ottawa, Ontario,
> Canada, and another in Winnebago, Neb.
