Exploring space is easier than exploring the ocean bottom… Pressure difference between a space capsule and the vacuum of space: Less than 1 atmosphere. Pressure difference between a submersible at the Titanic and the surrounding water pressure: Nearly 400 atmospheres (5,600 pounds per square inch)

“muh space exploration”. Please fucking stop with that bullshit. No one here wants to go to space. We want to preserve our ecology because Earth is our 1 home and we will save her with indigenous knowledge and ending capitalism. You promote space shuttle to create demand for yourself, you dumb nerd

I should probably look up instead of asking directly, but what about thermal loss? (First two things I would start worry about is micrometeorites and radiation, but it's really not important for the very interesting fact you just shared.)
