Another spacewalk has been charted on the calendar to take place on Friday, March 5th. NASA and JAXA astronauts Kate Rubins and Soichi Noguchi will venture outside the orbiting outpost to vent ammonia from the Early Ammonia System and complete several other tasks. The pair will install a “stiffener” on the Quest airlock thermal cover to prevent it from blowing out when residual atmosphere escapes as the hatch is opened. Glover began addressing this issue on a previous spacewalk by installing a stronger magnet to keep the cover closed. The crew also will remove and replace a wireless video transceiver assembly. Rubins will be EV 1 and Noguchi will be EV 2.
Spacewalks typically occur between the time frame of five to eight hours once departing from their vehicle, this is why a spacewalk is referred to as an EVA (extravehicular activity). Glover was a part of the flight crew overseeing the first operational flight of the Dragon 2 vehicle for human exploration on mission SpX USCV-1. Rubins became the 60th woman to fly in space once launching a Soyuz spacecraft to the International Space Center, later on being involved in Expeditions 48 and 49.
