Spacecraft Seat Standards Lead to Comfort in Your Car

In the beginning, safety outweighed comfort in spacecraft designs for human space travel. Capsules like Gemini and Apollo were small, and most of the flight activities were performed while the crew was strapped to their seats. Later, NASA devoted more attention to understanding how a spacecraft could provide comfort as well as safety and function to astronauts. NASA examined the neutral body posture (NBP), or the posture the human body naturally assumes in microgravity.
