Space Station Crew Removes Ammonia Pump, Next Spacewalk Set for Tuesday

NASA astronauts Rick Mastracchio and Mike Hopkins completed a 5 hour and 28 minute spacewalk Saturday to remove a faulty ammonia pump on the International Space Station A second spacewalk to install a new unit now is scheduled for Tuesday, Dec 24

The extra day will allow time for the crew to resize a spare spacesuit on the space station for use by Mastracchio During repressurization of the station�s airlock following the spacewalk, a spacesuit configuration issue put the suit Mastracchio was wearing in question for the next excursion -- specifically whether water entered into the suit�s sublimator inside the airlock The flight control team at NASA's Johnson Space Center in Houston decided to switch to a backup suit for the next spacewalk

This issue is not related to the spacesuit water leak that was seen during a July spacewalk by European Space Agency astronaut Luca Parmitano and NASA�s Chris Cassidy Both Mastracchio and Hopkins reported dry conditions repeatedly throughout Saturday�s activities and the two were never in danger

NASA Television coverage of Tuesday�s spacewalk will begin at 6:15 a m EST The spacewalk scheduled to begin at 7:10 a m
