Highlights from the 5 hours, 30 minutes long Spacewalk.
Astronauts Chris Cassidy (EV-1) and Tom Marshburn (EV-2) completed a contingency Spacewalk today at 18:14 UTC after spending 5 and a half hours outside replacing a cooling pump that is suspected to have been the cause of an ammonia leak spotted on Thursday. Whilst they did not see the leak in the old pump themselves whilst out there they did remain watching the new pump as controllers on the ground activated it - after a long inspection the crew reported they saw no leaks and ventured back inside the Station.
This Spacewalk occurred with just 48 hours of planning which was unprecedented in International Space Station history.
