How uncomfortable space suits took a toll on the first Americans who went to space

Going to space did change the bodies of the first US astronauts — but it was more linked to the long time they spent wearing uncomfortable space suits than the time they spent in zero gravity, according to new research. The US sent humans into space for the first time during Project Mercury, whose six flights spanned 1961 to 1963. Even if the flights were short, the astronauts were required to wear these suits for long periods of time. “Being in a space suit, particularly pressurized on a space walk, is a stressor,” Dorit Donoviel, an expert in space health also at the Baylor College of Medicine, tells The Verge in an email. Today, plenty of design and technical challenges remain for creating today’s space suits, and there is no “one-size-fits-all” solution.
