Space Station Crew Wraps Busy Week, Plans New Date for US Spacewalk 97
On Aug. 6, NASA astronauts Jessica Meir and Anil Menon concluded a 6-hour, 27-minute spacewalk outside the International Space Station. Meir and Menon successfully completed their primary objective of preparing the 3B power channel for the future installation of a roll out solar array. Toward the end of the spacewalk, a carbon dioxide sensor on Menon’s spacesuit indicated an unexpected data reading. Menon reported no other issues during the spacewalk.
Although the sensor returned to normal readings following removal of the suit, engineers on the ground will continue to evaluate over the coming days whether to change suits for the next spacewalk. As a result, NASA will move the next spacewalk to replace a Space-to-Ground antenna on the space station to Tuesday, Aug. 18. As of now, the third planned spacewalk this month remains scheduled on Tuesday, Aug. 25. The agency will provide additional spacewalk details early next week.
Afterward, the NASA astronauts joined flight engineers Jack Hathaway of NASA and Sophie Adenot of ESA (European Space Agency) for a post-spacewalk briefing with mission controllers on the ground. The quartet discussed their experiences with the engineers to ensure readiness for future spacewalks. Hathaway and Adenot helped the astronauts in and out of their spacesuits and monitored their spacewalking tasks on Thursday.
On Friday, NASA astronaut Jack Hathaway of studied Canadarm2 robotic arm operations planned to support the next spacewalk. NASA will soon name the spacewalkers who will replace a space-to-ground antenna to maintain high-speed data and communication transmissions between Mission Control Center and the space station.
ESA (European Space Agency) astronaut Sophie Adenot was back on exercise research working out with new and advanced gear to inform countermeasures that may improve muscle and bone health in microgravity. She first wore the EasyMotion-2 suit that sent electrical impulses and triggered muscle contractions to supplement her workout session on the advanced resistive exercise device in the Tranquility module. Afterward, she moved into the Columbus laboratory module and performed rope pull exercises on the European Enhanced Exploration Exercise Device (E4D). Researchers are evaluating the E4D’s effectiveness for use on missions to the Moon, Mars, and beyond.
Numerous science investigations and lab maintenance tasks also kept the three Expedition 75 cosmonauts busy at the end of the week. Roscosmos flight engineer Andrey Fedyaev started his shift measuring his blood pressure while wearing a series of cuffs on his arm, wrist, and fingers for a circulation system study. He wrapped up his day inspecting and cleaning smoke detectors in the Rassvet module. Flight engineer Pyotr Dubrov set up an automated Earth photography session to capture European and Asian landmarks then tested artificial intelligence tools to improve crew operations. Flight engineer Anna Kikina worked in the Zarya module photographing areas to identify optimal stowage locations and locate hardware.
