<\/a><\/figure>Tuesday brought the final preparations for tomorrow\u2019s spacewalk where two NASA astronauts will exit the International Space Station<\/a> and enter the vacuum of space for space station solar array upgrade work. The Expedition 74<\/a> crew members prepped spacesuits and reviewed procedures while working in some time for maintenance and science activities.<\/p>\n NASA astronauts Jessica Meir<\/a> and Chris Williams<\/a> will power on their spacesuits tomorrow morning for a planned six-and-a-half-hour spacewalk. The duo will exit the Quest airlock<\/a> to\u00a0install a modification kit and route cables<\/a>\u00a0on the port side of the station. It will be Meir\u2019s fourth spacewalk and Williams\u2019 first.<\/p>\n NASA\u2019s live coverage will begin at 6:30 a.m. on \u00a0NASA+<\/a>,\u00a0Amazon Prime<\/a>, and the agency\u2019s\u00a0YouTube<\/a>\u00a0channel. U.S. spacewalk 94 will begin at approximately 8 a.m.\u00a0<\/p>\n To gear up for tomorrow\u2019s spacewalk, Meir and Williams readied their spacesuits and equipment and also finalized the configuration of tools they\u2019ll use while in the vacuum of space. Later on, the duo was joined by NASA astronaut Jack Hathaway<\/a> and European Space Agency (ESA) astronaut Sophie Adenot to review procedural timelines and checklists.<\/p>\n Hathaway and Adenot teamed up throughout the day to complete a round of camera and lighting training. The duo also inspected and cleaned the orbital complex\u2019s ventilation system.<\/p>\n In the cupola<\/a>, Adenot scheduled in some time to photograph the Moon. As part of the Earthshine<\/a> experiment, crew members will take photographs of the lunar surface during different phases to study changes in Earth\u2019s reflectance of light. The photos are then analyzed by ground teams to help scientists improve climate models.\u00a0<\/p>\n In the morning, Commander Sergey Kud-Sverchkov\u00a0worked with flight engineer Sergei Mikaev\u00a0to load up and prepare flight simulation training software. Later on, the two cosmonauts worked in the Zvezda Service Module<\/a> to gather equipment for future inspections. Kud-Sverchkov\u00a0then took inventory of cargo to be loaded into the Progress 93 cargo spacecraft while Mikaev filmed his crewmates as they conducted science, maintenance, and exercise to document life aboard the space station. Flight engineer Andrey Fedyaev spent his day conducting maintenance before attaching sensors to his forehead, fingers and toes to capture blood flow data for health analysis.<\/p>\n Learn more about station activities by following the\u00a0<\/em>space station blog<\/em><\/a>,\u00a0<\/em>@space_station<\/em><\/a>\u00a0on X, as well as the\u00a0<\/em>ISS Facebook<\/em><\/a>\u00a0and\u00a0<\/em>ISS Instagram<\/em><\/a>\u00a0accounts.<\/em><\/p>\n Get the latest from NASA delivered every week.\u00a0<\/em>Subscribe here<\/em><\/a>.<\/em><\/p>\n Powered by WPeMatico<\/a><\/small><\/p>\n Get The Details…<\/a><\/p>\n Abby Graf <\/p>\n","protected":false},"excerpt":{"rendered":" Tuesday brought the final preparations for tomorrow\u2019s spacewalk where two NASA astronauts will exit the International Space Station and enter the vacuum of space for space station solar array upgrade work.
