Three NASA astronauts remain focused on preparations for next week’s spacewalk at the International Space Station. The rest of the Expedition 60 crew focused on biology research and a pair of docked spaceships.
Flight Engineer Christina Koch has been supporting spacewalkers Nick Hague and Andrew Morgan, as they get ready for the fifth spacewalk of the year on Aug. 21. The pair will install the new International Docking Adapter-3 (IDA-3) to the Harmony module’s space-facing port during the six-and-a-half-hour job.
Koch printed out checklists the spacewalkers will wear on their spacesuit cuffs and verified the spacesuits are the correct size. She also joined Hague and Morgan reviewing next week’s spacewalk procedures. The spacewalking duo also set up the Quest airlock where they will collect their tools and suit up ahead of their excursion.
Robotics controllers will remotely command the Canadarm2 to detach the IDA-3 from the rear portion of the SpaceX Dragon on Monday. They will maneuver the new docking port to a pressurized mating adapter on top of Harmony readying it for Wednesday’s spacewalk. Hague and Morgan in their U.S. spacesuits will then route cables and configure hardware readying the IDA-3 for new SpaceX and Boeing crew ships.
Luca Parmitano, a European Space Agency (ESA) astronaut on his second station mission, worked on a biology experiment today with potential benefits for the medicine industry. He tended to stem cell samples growing in a specialized incubator to help researchers understand cell behavior in space.
Cosmonauts Alexey Ovchinin and Alexander Skvortsov checked out two docked Soyuz crew ships today. The duo tested and recharged communications gear in the vehicles and continued packing gear for return to Earth.
