NASA has been using space suits on the ISS that were originally expected to only make it in service until 1993. However, with operations beginning to pick up on the ISS over the years NASA has had to refurbish these suits multiple times. The latest report to Congress sets the stage for another round of refurbishment and the remaining 11 space suits are expected to remain in service until at least 2024. Could you imagine wearing something so integral to your life that's been around for decades? Without a doubt our astronauts are definitely the right stuff. The space suits, or extra-vehicular activity suits (EVAs) worn by Nasa astronauts when they visit the ISS were first put together in 1978, designed to be used during short Space Shuttle missions before returning to Earth for maintenance. These were named the extravehicular mobility units, or EMU.
