Three Worldwide Area Station (ISS) crew members will conduct the primary of a pair of spacewalks on Sunday, February 28, 2021, to prepared the station for photo voltaic array upgrades. Stay protection will air on NASA TV, starting at 4:30 a.m.EST (09:30 UTC; translate UTC to your time), with the astronauts scheduled to exit the station’s Quest airlock about 6:00 a.m. EST (11:00 UTC) The spacewalk will final roughly 6 half of hours. Watch here.
The second spacewalk is scheduled for Friday, March 5.
On Sunday, NASA flight engineers Kate Rubins and Victor Glover, and Japan Aerospace Exploration Company (JAXA) astronaut Soichi Noguchi, will step out of the area station to start assembling and putting in modification kits required for upcoming solar array upgrades. In accordance with a NASA statement:
The present photo voltaic arrays are functioning properly, however have begun to point out indicators of degradation, as anticipated, as they had been designed for a 15-year service life. The primary pair of photo voltaic arrays had been deployed in December 2000 and have been powering the station for greater than 20 years. Later this 12 months, the brand new photo voltaic arrays might be positioned in entrance of six of the present arrays, rising the station’s complete obtainable energy from 160 kilowatts to as much as 215 kilowatts.
Spacewalks are the main focus now because the Exp 64 crew begins unloading 4 tons of cargo from the brand new @NorthropGrumman #Cygnus U.S. area freighter. Extra… https://t.co/nTzCvgAoVk pic.twitter.com/b5snu4Ebjf

On the Friday, March 5, spacewalk, two astronauts will vent ammonia from the Early Ammonia System and full a number of different duties. According to NASA:
The pair will set up a “stiffener” on the Quest airlock thermal cowl to forestall it from blowing out when residual environment escapes because the hatch is opened. Glover started addressing this difficulty on a earlier spacewalk by putting in a stronger magnet to maintain the quilt closed. The crew additionally will take away and exchange a wi-fi video transceiver meeting.
Backside line: On Sunday, February 28, watch reside protection as three astronauts carry out the primary in a pair of Worldwide Area Station (ISS) spacewalks to prepared the station for photo voltaic array upgrades. The best way to watch.
