SPACE reports Russian cosmonauts Sergey Ryzhikov and Alexey Zubritsky completed a 6 hour and 54-minute spacewalk outside the International Space Station “on Tuesday (Oct. 28) to continue and expand on the work they began during an extravehicular activity (EVA) on Oct. 16.”

SPACE reports Russian cosmonauts Sergey Ryzhikov and Alexey Zubritsky worked outside the International Space Station (ISS) on Thursday (Oct. 16), “conducting a spacewalk to install a semiconductor materials experiment, as well as retrieve and jettison a no-longer-needed camera from the exterior of the orbiting complex.”

AP News reports, “An astronaut who missed out on the first all-female spacewalk because of a spacesuit sizing issue got her chance six years later on Thursday. NASA’s Anne McClain emerged from the International Space Station alongside Nichole Ayers. Both military officers and pilots, they launched to the orbiting lab in March to replace NASA’s two stuck astronauts, who are now back home.”

AP News reports, “NASA’s two stuck astronauts took their first spacewalk together Thursday, exiting the International Space Station almost eight months after moving in. Commander Suni Williams and Butch Wilmore floated out to perform maintenance work and wipe the station’s exterior for evidence of any microbes that might still be alive after launching from Earth and escaping through vents.”

SPACE reports, “Two Chinese astronauts continued installing space debris protection outside the nation’s Tiangong space station” during a July 3 EVA. “Ye Guangfu and Li Cong, two members of the three-person Shenzhou 18 mission, spent about 6.5 hours working outside Tiangong on Wednesday (July 3). Li Guangsu assisted the expedition from inside Tiangong, operating the station’s robotic arm.”

SPACE reports that a pair of Chinese astronauts spent eight hours outside their Tiangong Space Station last weekend to carry out repairs on solar arrays. According to the report, “it was the second extravehicular activity, or spacewalk, of the ongoing Shenzhou 17 crewed mission at China’s Tiangong space station.”

CNN reports that NASA astronauts Jasmin Moghbeli and Loral O’Hara “marked their first spacewalk this month with a tool bag floating through space.” The pair “concluded their maintenance work outside the International Space Station (ISS) in six hours and 42 minutes, according to the space agency.” The spacewalk on November 1 “saw Moghbeli and O’Hara complete works on the station’s solar arrays, which track the sun, but they ran out of time to remove and stow a communications electronics box.” Leaving this task “for a future spacewalk, the pair instead conducted an assessment of how the job could be done.” During the mission, a tool bag “gave them the slip and was ‘lost,’ NASA said, with flight controllers spotting it using the ISS’ external cameras.” Fortunately, the tools “were not required for the remainder of their tasks.” According to EarthSky, “a website tracking cosmic events, the tool bag is currently orbiting Earth ahead of the ISS, and can potentially be spotted from Earth with a pair of binoculars during the next few months until it disintegrates in our planet’s atmosphere.”

Spaceflight Now reports that two Russian spacewalkers “floated outside the International Space Station Wednesday and isolated a leaking radiator as planned, apparently causing residual coolant still trapped inside to make its way to the leak site and spew out into space.” Cosmonaut Oleg Kononenko “planned to sop up the pooling coolant with a cloth towel, but was told to leave the area immediately when he reported some of the liquid had made it onto a safety tether.” The tether “was secured in a bag and procedures were already in place to make sure the cosmonauts’ spacesuits were clear of any such contamination before they re-entered the space station at the end of the spacewalk.” In the meantime, Kononenko and crewmate Nikolai Chub “pressed ahead with work to attach a small synthetic aperture radar antenna to the hull of the Nauka module.” One of its four panels “failed to fully deploy and lock in place, and officials said adjustments would be made in a future spacewalk.” Finally, Kononenko and Chub “released a small student-built ‘nanosatellite,’ but the solar sail propulsion system it was designed to test failed to deploy.” After making a final attempt “to coax the balky radar panel into place, the cosmonauts called it a day.”

SPACE reports NASA officials have postponed a planned spacewalk from the ISS “as a precautionary measure after a leak of ammonia coolant was spotted Monday (Oct. 9) in a backup radiator on the Russian Nauka science module. Another spacewalk on Oct. 20 is also postponed and new dates will be announced shortly, NASA officials stated.”
