<\/a><\/figure>NASA astronaut\u00a0Jessica Meir<\/a> and ESA (European Space Agency) astronaut\u00a0Sophie Adenot<\/a> concluded their spacewalk outside the International Space Station<\/a> at 3:29 p.m. EDT.<\/p>\n During the 6-hour, 49-minute spacewalk, Meir and Adenot\u00a0installed a new retroflector on the forward port of the space station\u2019s Harmony module to support spacecraft navigation during rendezvous and docking operations. The duo replaced a high-definition camera on the station\u2019s truss and completed a swab of the space station\u2019s exterior for microorganisms. They also partially completed work to install jumper cables for electrical systems and started work to prepare for the replacement of the Alpha Magnetic Spectrometer\u2019s heat-rejecting radiator on a future spacewalk.<\/p>\n Mission Control deferred installing the remaining guide studs for the spectrometer\u2019s replacement radiator so engineers can develop a plan to finish the work during a future spacewalk. As the crew fell behind the timeline, the mission control team also shifted completion of the remaining jumper cables and other noncritical tasks to a later date.<\/p>\n During the spacewalk, Adenot experienced some mobility issues with her left arm. Meir took a look at Adenot\u2019s suit and determined the glove heater harness was likely getting caught and causing limited movement in the left shoulder joint. Unzipping the joint seemed to resolve the issue ahead of the crew entering the airlock.<\/p>\n U.S. spacewalk 99 was Meir\u2019s seventh and Adenot\u2019s third. Meir now ranks third all-time among woman at NASA for total spacewalks, behind Peggy Whitson (10) and Suni Williams (9). It also was the 284th spacewalk in support of space station assembly, maintenance, and upgrades.<\/p>\n It also was the 284th spacewalk in support of space station assembly, maintenance, and upgrades.<\/p>\n Learn more about station activities by following the <\/em>space station blog<\/em><\/a>, <\/em>@space_station<\/em><\/a> on X, as well as the <\/em>ISS Facebook<\/em><\/a> and <\/em>ISS Instagram<\/em><\/a> accounts.<\/em><\/p>\n Get the latest from NASA delivered every week. <\/em>Subscribe here<\/em><\/a>.<\/em><\/p>\n Powered by WPeMatico<\/a><\/small><\/p>\n Get The Details…<\/a><\/p>\n Mark A.
