NASA astronauts Nick Hague and Andrew Morgan switched their spacesuits to battery power this morning at 8:27 a.m. EDT aboard the International Space Station to begin a spacewalk planned to last about six-and-a-half hours. The two flight engineers will install the second of two international docking adapters (IDAs) that will enable future arrivals of Boeing and SpaceX commercial crew spacecraft.
NASA Television coverage of today’s spacewalk is ongoing and available on the agency’s website.
Hague is designated extravehicular crew member 1 (EV 1), his helmet camera is #11, and he is wearing the spacesuit with a red stripe. Morgan will be extravehicular crew member 2 (EV 2), his helmet camera is #18, and he is wearing the suit with no stripes.
The docking adapter arrived to the space station July 27 on a SpaceX Dragon cargo resupply spacecraft. On Monday, ground controllers used the Canadarm2 robotic arm, and its attached “Dextre” Special Dexterous Manipulator, to extract the IDA from the trunk of Dragon and position it just 2 feet away from Pressurized Mating Adapter-3 (PMA) located on the space-facing side of the station’s Harmony module. Once the IDA is moved to a surface to surface contact with the PMA, Hague and Morgan will begin work to hook up tethers in advance of NASA astronaut Christina Koch sending commands to close the hooks between the two docking ports. Once the hooks are closed, Hague and Morgan will press ahead to route and connect power and data lines for future use of the IDA.
The spacewalk is the 218th in support of station assembly, maintenance and upgrades and the fifth outside the station this year. It will be the third spacewalk for Hague and the first for Morgan.
