ISS News: December 2013 Archives

"Review of NASA's Evidence Reports on Human Health Risks -- Letter Report [Institute of Medicine]: NASA has asked the Institute of Medicine to provide independent reviews of more than 30 publicly available evidence reports on human health risks for long-duration and exploration space flight. This letter report examines evidence reports on the risk of injury from dynamic loads, the risk of therapeutic failure due to ineffective medication, and the risk of spaceflight-induced hypertension and visual alterations."

ISS EVA Update

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."

NASA Postpones Orbital Launch and Sets Spacewalks to Repair ISS

"NASA managers are postponing the upcoming Orbital Sciences commercial cargo resupply mission to the International Space Station to proceed with a series of spacewalks to replace a faulty pump module on the space station. NASA Television will air a news briefing at 3 p.m. EST on Wednesday, Dec. 18 to preview the spacewalks. Orbital Sciences' Cygnus spacecraft, atop its Antares rocket, now will launch no earlier than January. The postponement of the Antares launch will allow ample time for the station crew to focus on repairing a faulty pump module that stopped working properly on Dec. 11."

Cygnus Launch To ISS Delayed

NASA Delays Cygnus Launch Due to ISS Cooling Issue

"The launch has been delayed to no earlier than Thursday, Dec. 19 to enable engineers to continue their analysis of data involving a suspect Flow Control Valve in a pump module on the starboard truss of the station that malfunctioned on Wednesday. Orbital's Antares rocket and the Cygnus commercial cargo vehicle are now scheduled to launch from Pad 0A at the Wallops Flight Facility, Va. no earlier than Dec. 19 at 9:19 p.m. EST. NASA TV coverage of launch will begin at 8:45 p.m. EST."

NASA Statement on Space Station Cooling Loop Shut Down

"Earlier Wednesday, the pump module on one of the space station's two external cooling loops automatically shut down when it reached pre-set temperature limits. These loops circulate ammonia outside the station to keep both internal and external equipment cool. The flight control teams worked to get the cooling loop back up and running, and they suspect a flow control valve actually inside the pump module itself might not be functioning correctly."

Teams Working Cooling System Issue; Station Crew Carries on With Research

"Mission managers have deferred the decision on whether to proceed with or postpone the launch of the Orbital Sciences' Cygnus commercial cargo craft until more is known about the flow control valve issue. Cygnus is currently scheduled to launch Dec. 18 from Wallops Flight Facility in Virginia and rendezvous with the station on Dec. 21."
