I recently found this list of spaceflight-related accidents and incidents. There are some truly harrowing experiences, including an astronaut whose helmet began to fill with water during an EVA. He was having difficulty speaking by the time he was removed from the suit. https://en.wikipedia.org/wiki/List_of_spaceflight-related_accidents_and_incidents https://en.wikipedia.org/wiki/List_of_spaceflight-related_ac...

For those not in the exclusive clique and up on the jargon: EVA = Extra Vehicular Activity.

    Never heard of it. But thanks for not calling it "KSP".

      Since KSP is, of course, the Korellia Secret Police (who can be identified by a 'KSP' tattoo on the hand, which is only visible under ultraviolet light.)

      How about Vektor Grafix' Shuttle from 1992: https://en.wikipedia.org/wiki/Shuttle_(video_game) https://en.wikipedia.org/wiki/Shuttle_(video_game) There is an EVA mission where you have to move around with the MMU.

Chris Hadfield told a good story about "going blind in space" in his TED talk: https://www.youtube.com/watch?v=Zo62S0ulqhA&t=31s https://www.youtube.com/watch?v=Zo62S0ulqhA&t=31s

About the EVA > By December, 2013, NASA had determined the leak to have been caused by a design flaw in the Portable Life Support System liquid coolant. The designers failed to take into account the physics of water in zero-g, which unintentionally allowed coolant water to mix with the air supply. They did not take into account that a space suit will primarily be used in… space. wat?!?

That's not entirely fair. It's easy enough to know that something will be used in particular circumstances, but not to realise all of the consequences. Water behaves very, very weirdly in microgravity as compared with here on Earth, and unless you, personally, have experienced it and experimented with it, it's very, very easy not to notice something, or to expect something other than what actually happens.

  I went digging because I was confused about that too, from https://en.wikipedia.org/wiki/Luca_Parmitano#Expedition_36/37 https://en.wikipedia.org/wiki/Luca_Parmitano#Expedition_36/3... > Engineers found that contamination had clogged one of the suit's filters, causing water from the suit's cooling system to back up. So one of the failure scenarios didn't behave well in zero gravity, I think that's (more) reasonable.

Parmitano is going back to the ISS in July. Also he is going to be the first Italian to take command of the space station.

Dave Wolf told stories about his EVAs to Radiolab. It's a good listen: https://www.wnycstudios.org/story/242184-dark-side-earth https://www.wnycstudios.org/story/242184-dark-side-earth
