On Friday (October 20, 2017) two astronauts aboard the International Space Station (ISS) will perform the last of a trio of spacewalks in October.
NASA TV coverage of Friday’s spacewalk will begin at 6:30 a.m. EDT (10:30 UTC). Expedition 53 Commander Randy Bresnik and Flight Engineer Joe Acaba will start the spacewalk at approximately 8:05 a.m. EDT (12:05 UTC). Translate to your timezone.
The goal of the spacewalks is to perform station maintenance. According to a NASA statement:
Bresnik and Acaba will replace a fuse on Dextre’s enhanced orbital replacement unit temporary platform; install an enhanced HD camera on the Starboard 1 lower outboard truss; remove thermal insulation on two spare units to prepare those components for future robotic replacement work, if required; and replace a light on the Canadarm2’s new latching end effector installed during the first spacewalk Oct. 5. The final lubrication of the new end effector and the replacement of a camera system on the Destiny Lab will be deferred for a future spacewalk.
Bottom line: The third ISS spacewalk in October 2017 is scheduled for Friday, October 20. How to watch.
