On Tuesday, NASA astronauts Anil Menon and Jessica Meir, along with European Space Agency astronaut Sophie Adenot and Jack Hathway, completed a six-hour and 30-minute spacewalk to install a high-speed antenna outside the International Space Station. Upon concluding their mission, the four astronauts cleaned the Quest airlock, refilled suit water tanks, and recharged suit batteries during a post-spacewalk conference.
The next spacewalk is set for Tuesday, September 1, where Adenot and Meir will replace a visiting spacecraft navigational aid, install jumper cables for data relay systems, prepare the Alpha Magnetic Spectrometer for future upgrades, and replace a high-definition camera.
On Wednesday, Menon collected and processed saliva and hair samples for the RelaxPro investigation, which studies stress-related hormones and immune markers during long-term spaceflight. Meir also assisted Menon with his blood sample collection for the Venus Flow investigation, examining circulatory system health risks in long-duration space missions.
Additionally, Meir conducted an eye exam of Menon, capturing images of his retina, cornea, and lens for potential space-induced vision issues. Hathaway performed medical imaging setup and inspected research equipment during his shift, while Roscosmos flight engineers Pyotr Dubrov, Anna Kikina, and Andrey Fedyaev completed various maintenance tasks and measurements for cardiac activity and heart rate monitoring.
