These Astronauts Are Getting Sealed In A Cave To Practise Life In Space

An underground cave is precisely the wrong direction if you’re hoping to go into space — so why is the European Space Agency sending the latest batch of ISS-bound astronauts on a spelunking expedition? To practise for life in a sealed tin can, of course.

What Those Frost Patterns On Your Car Window Have To Do With Ice In Space
