What would happen if an astronaut on a space walk had an empty rubber ballon and filled it with air? Would it just take less air to fill or would it pop with just adding the slightest amount of air?
In: Planetary Science
The former; it’s been done in real life. NASA launched some in the 1960s (Project Echo) to test passive communication satellites, and there was one launched in 2018 as an art project.
