One Year Aboard the Space Station
How does one year in space affect your immune system? What about your mental health? The International Space Station is conducting a study with twin astronauts Scott and Mark Kelly. Scott speaks to Ira from the International Space Station about living in space for the next year, and his Earth-bound brother Mark tells us what changes they’re interested in measuring during the year.
Mark Kelly is a NASA astronaut based in Tucson, Arizona.
Scott Kelly is a NASA astronaut and Expedition 43 flight engineer based at the International Space Station.
