A former NASA astronaut has revealed the rules that have to be followed if someone dies in space. Former commander of the International Space Station (ISS), which is in Earth's orbit and constantly manned by a group of astronauts, Chris Hadfield, explained that NASA prepares its personell using "death simulations".

For most of us, pondering the logistics of death doesn’t involve zero gravity, freezing temperatures, or decomposing in a vacuum. But for NASA, where space travel transforms every “what if” into a life-or-death scenario,

So, the space agency does have a protocol for astronauts to follow in case someone does die in space. Astronaut and former commander of the International Space Station (ISS), Chris Hadfield, explained NASA even runs ‘death simulations’ with astronauts to lay out the scenarios.
