Critical ISS EVA Now Planned For Saturday

NASA Moves Space Station Repair Spacewalk To Saturday

"The first of two spacewalks by NASA astronauts to replace a failed ammonia pump on the International Space Station has been moved to Saturday, Aug. 7. A second spacewalk is planned for Wednesday, Aug. 11, to complete the repairs. Teams of flight controllers, engineers, and spacewalk experts have made significant progress in preparing for the first spacewalk, but need an additional day to get ready. The additional time allows for final procedures to be sent late Thursday to the station, giving the crew a full day to review the plans developed by Mission Control. Managers also moved the second spacewalk to Wednesday to give the crew more time to rest and prepare."

"NASA astronauts and engineers are refining plans for two spacewalks by astronauts Douglas Wheelock and Tracy Caldwell Dyson to replace a large ammonia pump module that shut down Saturday, knocking out one of the International Space Station's two cooling loops. The astronauts hope to carry out the first spacewalk Friday morning, starting at 6:55 a.m. EDT, and a second excursion Monday to finish the job, one of the so-called "big 14" on a list of critical components that require spacewalk repair if problems crop up. NASA managers initially targeted Thursday for the first spacewalk and Sunday for the second, but decided late Monday they needed more time to review procedures."

International Space Station Repair Spacewalk Planned for Friday

"NASA has decided to wait until Friday to conduct a spacewalk to replace a failed ammonia pump module on the International Space Station. Mission managers, program managers, flight controllers, engineers, astronauts and spacewalk experts made the decision Monday evening after continuing to analyze and refine engineering requirements, and reviewing the results of an underwater practice session."
