Astronauts Prep for Maintenance Spacewalk Today on NASA TV
NASA Television coverage of today?s spacewalk with NASA astronauts Jasmin Moghbeli and Loral O?Hara is now underway and is also available on the NASA app, the space station blog and the agency?s website. The crew members of Expedition 70 are preparing to exit the?International Space Station?s Quest airlock for a spacewalk expected to begin about 8:05 a.m. EDT and last approximately six-and-a-half hours. Moghbeli and O?Hara will exit the station?s Quest airlock to remove an electronics box called the Radio Frequency Group from the station?s truss that was temporarily stowed after a faulty communications antenna was replaced in Dec. 2021. They also will replace one of 12 trundle bearing assemblies on a solar alpha rotary joint. The bearings enable the station?s solar arrays to rotate to track the Sun as the station orbits the Earth to collect and store electricity for power generation for station systems. Moghbeli will serve as extravehicular activity (EVA) crew member 1 and will wear a suit with red stripes. O?Hara will serve as extravehicular crew member 2 and will wear an unmarked suit. U.S. EVA 89 will be the first spacewalk for both crew members.
