NASA’s McClain and Ayers Finish Historic EVA, Advance ISS Solar Upgrade

NASA astronauts Anne McClain and Nichole Ayers accomplished the fifth all-female spacewalk, transferring an antenna and partially getting ready the International Space Station for a brand new set of photo voltaic arrays on Could 1st. Their 5-hour, 44-minute extravehicular exercise was accomplished after re-entering the Quest airlock, and it began to get re-pressurised. McClain and Ayers accomplished the vast majority of their targets. Nevertheless, they needed to postpone a few of the chores till a later spacewalk since they had been delayed and had restricted provides.

In regards to the mission

In response to NASA, Expedition 73 crewmates Anne McClain and Nichole Ayers started working at 9:05 a.m. EDT (1305 GMT) by carrying instruments and tools out to the port (or left) facet of the house station’s spine truss. They started assembling the attachment {hardware} for the seventh pair of Worldwide Area Station Rollout Photo voltaic Arrays, or IROSA. These shall be put in as soon as they arrive on a SpaceX Dragon industrial resupply companies mission later this 12 months.

Putting in smaller, extra environment friendly photo voltaic arrays will improve electrical energy era by as much as 30%, growing the station’s whole energy from 160 to 215 kilowatts. The spacewalkers constructed and put in the correct struts and the higher triangle of the mast canister modification package earlier than being advised to tidy up their workstations and proceed to the subsequent, extra necessary project.

Persevering with the Legacy of Feminine Spacewalkers

It was Ayers’s first spacewalk and McClain’s third. McClain has spent 18 hours and 52 minutes away from the house station. Rotating astronaut crews have repeatedly staffed the ISS since November 2000. This was the 93rd EVA from the U.S. Quest airlock and the 275th general to help the ISS’s set up, upkeep, and upgrading.

In October 2019, NASA astronauts Christina Koch and Jessica Meir carried out the primary all-female EVA. In January 2020, the pair carried out two additional spacewalks collectively. In November 2023, NASA’s Jasmin Moghbeli and Loral O’Hara accomplished a stroll alone.
