Space Station Repair Scheduled For Saturday

August 6th, 2010 - 7:41 pm ICT by Pen Men At Work  

August 6, 2010 (Pen Men at Work): Space station repair is in progress. The astronauts from NASA moved one of the spacewalks to repair an ammonia pump at the International Space Station. The second one will be removed on 7th August, Saturday. The repairs are expected to be completed by the 11th of August.

While the progress made by the team consisting of flight controllers, engineers and spacewalk experts can be termed as significant, they would need another day to prepare themselves. The additional period of 24 hours will actually give the crew enough time to go over the Mission control plans.

Doug Wheelock and Tracy Caldwell Dyson will form the team of repair engineers for Expedition 24 that will be aired on the NASA television as they perform their spacewalk. This will be the very first time for Tracy Dyson while Wheelock will be doing it for the fourth time. The spacewalk is scheduled to begin at 5:55 A.M. while the broadcast will start at 5 AM CDT.

Both the engineers will attempt to remove the large and ungainly ammonia pump which weighs 780 pounds. The pump had failed to work last Saturday. They are expected to install another pump on Monday. The station has four additional pumps which are kept as spares.

The malfunctioning pump has resulted in a curtailment of certain activities as well as experiments as the two operating pumps cannot cope with an excess of cooling requirements.

The NASA TV will also be airing a briefing from the NASA’s Johnson Space Center, two hours after each spacewalk gets completed. Mike Suffredini, International Space Station program manager; David Beaver, Expedition 24 spacewalk officer and Courtenay McMillan, Expedition 24 spacewalk flight director will be speaking on behalf of the NASA.
