If there’s one thing that scares me, it’s having a mechanical accident/breakdown, somewhere remote, and not being able to fix it or call for help. That idea scares me. So far, I’ve been ok.
Now, imagine that, but out in the middle of space, surrounded by an airless void, and unable to call for help, in a tin can with less technology than the iPhone in your pocket. Now what? You shit frozen bricks in your space suit, that’s what.
These tech fails in the early days of the space race, are far too harrowing to picture, and all the credit goes to the legitimate badass Astronauts and Cosmonauts for bolding going where no one’s gone before.
