The Human Test Subject Facility (HTSF) at the Johnson Space Center is
responsible for providing qualified test participants for ground-based
research. Currently, researchers are working to reduce the effects of space
flight on the human body. To accomplish this, researchers study people on
Earth, in a way that causes some of the changes the body goes through while
traveling in space without gravity. Healthy test subjects are needed from the
general population.
The Bed Rest Project Study Team at the Johnson Space Center is planning a series
of studies that support the scientific needs of the space program and will be
conducted over the next ten years. These studies will develop ways to keep
astronauts healthier and safer when they spend a long time in space without
gravity. NASA calls these methods countermeasures and uses them to minimize the
changes that occur to the body during space flight and enable the return of
normal body functions once back on earth.
Currently the HTSF is recruiting participants for the following studies:
