NASA scientists are working to find ways to keep astronauts healthier and safer when they spend a long time in space. Head down bed rest is a good way to mimic a person traveling in space without gravity.
Head-down bed rest helps researchers study people on earth in a way that causes some of the changes the body goes through while traveling in space without gravity. This study will show how much your body, tilted down slightly with head down and feet up, for 70 days, 24-hours a day, without getting out of bed, except for limited times for specific tests, is like an astronaut’s body during the weightlessness of space flight. Watching you will help scientists learn how an astronaut’s body will change in weightlessness during space flight in the future.
