NASA astronaut Jonny Kim and Anne McClain studied space biology to counteract the effects of weightlessness on the human body.
Expedition 73 crew packed the SpaceX Dragon cargo spacecraft for departure and practiced using the European robotic arm.
Biomedical hardware testing included a thigh cuff to prevent space-caused fluid shifts and sensors measuring exhalation rates to understand respiratory system effects.
Activities also involved investigating plasma physics, loading cargo into Dragon for undocking, training on the European robotic arm, and processing protein crystal samples for deep space missions.
