Vision, Immune System Studies and Hardware Inspections Keep Crew Busy

1 week ago | nasa.gov | Mark Garcia

Life science was back on the schedule for Wednesday as the Expedition 73 crew studied how living in space affects eye structure and cellular immunity. The International Space Station residents also maintained the upkeep of exercise gear, life support components, and orbital plumbing hardware. The ongoing space biology investigations aboard the orbital lab constantly informs doctors how astronauts adapt to months of living and working in weightlessness.
