iss073e0076065 (May 19, 2025) — NASA astronaut Anne McClain helps NASA astronaut Jonny Kim conduct an ultrasound aboard the International Space Station. Ultrasounds allow real-time observation of what is happening inside an astronaut’s body in space, such as changes in arteries and the effects of fluids shifting towards the head. In this photo, the checkup is being conducted as a part of the Thigh Cuff study, research to understand if wearing a tight cuff around the leg can help to mitigate headward fluid shifts. Credit.
