NASA Astronauts Terry Virts and Butch Wilmore stepped outside the International Space Station three times over an eight day period to perform maintenance on the outside of the station. The changes are all geared to the reconfiguration of the station to allow the arrival of a new Inflatable module and two docking adapters to be used by the SpaceX and Boeing crewed vehicles.
Over the three space walks which totals 18h XXm the two astronauts completed the following tasks
- Rigged and routed power and data cables at the forward end of the Harmony module as part of preparations for the installation of the International Docking Adapter at PMA-2.
- Completed power and data cable routing at the forward end of the Harmony module.
- Removed launch locks from forward and aft berthing ports of Tranquility to prepare for relocation of the Permanent Multipurpose Module and the installation of the Bigelow Expandable Activity Module.
- Lubricated end effector of Canadarm2.
- Finished cable routing, antenna and retro-reflector installation on both sides of the ISS truss and on other modules in preparation for the installation of the International Docking Adapter at PMA-2 and 3.
The two astronauts spent a total of 19h 2m outside the station during the three EVA’s.
