Station Crew Works Earth, Human Research and Preps for Cargo Missions
The Expedition 75 crew spent Thursday cleaning up after a spacewalk, servicing advanced Earth imagery, and studying how to protect the human body in microgravity. The International Space Station is also gearing up for a cargo mission swap next week to replenish the seven orbital residents.

The Expedition 75 crew aboard the International Space Station (ISS) devoted Thursday to cleaning up after a spacewalk, maintaining advanced Earth observation equipment, and examining ways to safeguard human health in the weightless environment. Station commander Jessica Meir, alongside flight engineer Sophie Adenot, stored their spacewalk tools and tethers in the Quest airlock.
Meir then proceeded to perform an eye exam, with real-time imaging of her retina, cornea, and lens being monitored by researchers on the ground. Adenot donned the EasyMotion-2 suit, which applied electrical impulses to her muscles, enabling scientists to measure contractions and potentially augment their space workout regimen.
During the day, flight engineer Jack Hathaway collaborated with Meir, transferring supplies and equipment in and out of the Northrop Grumman Cygnus XL cargo spacecraft attached to the Unity module's Earth-facing port. Hathaway also managed the maintenance of the Mochii miniature electron microscope and the MUSES high-resolution, hyperspectral Earth-imaging system.
Anil Menon, another NASA flight engineer, worked within the Kibo laboratory module to prepare advanced Earth observation gear for removal. This gear was intended to demonstrate the transmission of ultra-high-resolution hyperspectral imagery and investigate atmospheric dynamics.
Roscosmos flight engineer Pyotr Dubrov was tasked with loading and securing trash and obsolete equipment within the Progress 94 resupply spacecraft before its anticipated undocking from the ISS on Monday. Progress 94 would be replaced by Progress 96 after its launch from Kazakhstan's Baikonur Cosmodrome on September 9, followed by a two-day automated docking to the Poisk module.
On the other hand, Roscosmos flight engineers Anna Kikina and Andrey Fedyaev worked together during the crew's sleep shift, installing Earth observation cameras to capture images of Earth landmarks automatically. Kikina also measured her blood pressure using cuffs on her arm, wrist, and fingers for a long-term cardiovascular investigation.
Fedyaev's duties included transferring fluids from the Progress 94 spacecraft, inspecting laptop computers, and testing camera sensors.
