Gregory Sachs is spending 45 days soaring through the stars aboard a spaceship designed by NASA. The only catch is that the ship is parked in Texas.
Sachs is part of HERA XVI, also known as Human Exploration Research Analog. He and three others are spending 45 days locked in the simulated spaceship so NASA can study what prolonged isolation and living in close quarters can affect people. Sachs and his crewmates began their journey on Feb. 3 and won’t return until March 19.
