Expedition 24
Expedition 24 faced cooling pump failure and docking ring issues.
Last updated
The twenty-fourth long-duration ISS crew originally scheduled two spacewalks, one Russian and one American. The American EVA was later revised, and an additional U.S. spacewalk was added to the mission.
Incidents
On 31 July 2010, the crew was awakened by an alarm caused by a failed cooling pump that tripped a Remote Power Controller, cutting power to some ISS systems. Astronauts Tracy Caldwell Dyson and Doug Wheelock assisted ground controllers in re-powering two main power buses and one Control Moment Gyroscope. After the work was complete, Capcomm James Kelly told the crew they could go back to bed. Shortly afterward, another alarm sounded when ground controllers attempted to restart the pump module.
A failure in the docking ring on the Mini-Research Module 2 (MRM2) Poisk delayed the planned landing of Soyuz TMA-18. The spacecraft undocked on 25 September 2010 instead of 24 September. The failure is believed to be due to a faulty micro-switch on the hatch and a drive gear with two broken teeth.
Did You Know?
- Additional spacewalking tasks were added to remove and replace a failed ammonia pump module.
- The spacewalk in Orlan suits was performed from the Pirs docking compartment.
