The Evolution of the Space Suit
I was researching the ISS the other day and that got me to thinking about what astronaunts wear – most specifically, their spacesuits! I began to look into how the Spacesuit has changed over the years and its actually really interesting how they started out as looking like tin-foiled jumpsuits to bulky marshmallows. I suppose this makes sense as scientists and NASA began to learn more about what life support systems, materials/fabrics, and components would have to be added in order to be the most life sustaining. Case in point? Astronaunts now use two suits when in space: the Advanced Crew Escape Suit (ACES) and the Extravehicular Mobile Unit (EMU). The ACES is the orange suit you’ve probably seen, is worn during take off, and is fabric based. The EMU is the huge 300lb suit that is worn when performing tasks outside the shuttle or space station.
The final suit above is a new suit that NASA is working on for man’s return to the moon by 2020. It is designed to provide more stability and flexibility and allow the astronaunts the ability to work outside the ISS. It’s also to be the suit for planned trips to Mars.
