Space Flight Simulation Study

The Flight Analogs Project Team at the Johnson Space Center is conducting a series of studies that support the scientific needs of the space program.
These studies develop methods 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.
Healthy test subjects are needed for these studies.
The Test Subject Screening (TSS) at the Johnson Space Center is responsible for providing qualified test participants for ground-based research.
