Crew Studies Medicine and Physics, Works on Spacesuits and Earth Photo Gear
Vein scans, ultra-hot physics, and Earth observations were the main research activities aboard the International Space Station on Wednesday. The Expedition 75 crew members rounded out their mid-week shift and swapped out spacesuit components and serviced life support gear.

On August 28, Expedition 75 crew members Anil Menon, Sophie Adenot, Jessica Meir, Anna Kikina, and Pyotr Dubrov gathered to celebrate Meir's 400 cumulative days in space. The International Space Station crew prioritized three main research activities during their shift: vein scans, ultra-hot physics, and Earth observations.
The crew members conducted vein scans using the Ultrasound 3 biomedical device, with Meir serving as the crew medical officer and operating the device with real-time assistance from doctors on the ground. The scans observed how weightlessness affects blood flow in crew members, helping to promote healthy crews on long-duration missions to the Moon, Mars, and beyond.
Flight engineer Sophie Adenot of the European Space Agency worked inside the Kibo laboratory module, cleaning the Electrostatic Levitation Furnace (ELF). ELF uses electric fields to float and heat materials in microgravity, allowing scientists to observe thermophysical properties unobtainable in Earth's gravity. Adenot removed samples, cleaned components, and installed new samples inside the research furnace.
After the vein scans, Menon moved into the Quest airlock to swap out a radio communications unit on a spacesuit. This unit will be returned to Earth for refurbishment during the SpaceX Crew-12 mission. NASA flight engineer Jack Hathaway worked on replacing filters throughout Wednesday to maintain a safe, breathable environment on the station.
Roscosmos cosmonauts Anna Kikina and Pyotr Dubrov joined NASA astronauts Jessica Meir and Anil Menon in the Columbus laboratory module for regularly scheduled research. They swapped, configured, and activated Earth observation gear, capturing images of Earth landmarks and the effects of various phenomena in numerous wavelengths. These images reveal details invisible to the human eye, such as storms, wildfires, and volcanic activity.
Kikina and Dubrov also inspected custom-fitted seat-liners that crews use when returning to Earth aboard a Soyuz spacecraft. Fedyaev worked on Roscosmos orbital plumbing components and took inventory of hardware stowed inside the Zvezda service module.
