Date of beginning	Time of beginning	Duration	Crew & Remarks
07.08.2010	- UT	8h 03m	Dyson and D.Wheelock, station "ISS" They started disconnecting umbilicals from the broken space station coolant pump. However, difficulty unplugging one of the ammonia lines consumed a couple of hours and a leak seen from that connector once it finally cooperated prevented the astronauts from progressing any further in their work.
11.08.2010	- UT	7h 26m	Dyson and D.Wheelock, station "ISS" Removing the old pump and stowing it on the Mobile Base System on the station's truss while preparing the replacement pump for its removal from a stowage platform adjacent to the Quest airlock and its installation on the truss during a third spacewalk.
16.08.2010	- UT	7h 20m	Dyson and D.Wheelock, station "ISS" Installation of a spare ammonia pump module on the S1 Truss.
24.06.2024	- UT	0h 31m	Dyson and M.Barratt, station "ISS" NASA says today's spacewalk lasted due to a water leak only 31 minutes; that's the time between the switch to battery power and the moment the crew reconnected to station power.
