There have been several people that have died in space.
There have been at least 18 deaths in space which include preparation for entry in space and those in space and some on return to earth from space.
A total of 18 people have lost their lives either while in space or in preparation for a space mission, in four separate incidents.
Given the risks involved in space flight, this number is surprisingly low.
The remaining four fatalities during spaceflight were all cosmonauts from the Soviet Union.
As of March 2021, in-flight accidents have killed 15 astronauts and 4 cosmonauts, in five separate incidents.
Three of them had flown above the Kármán line (edge of space), and one was intended to do so.
No Soviet or Russian cosmonauts have died during spaceflight since 1971.
Remains are generally not scattered in space so as not to contribute to space debris.
Remains are sealed until the spacecraft burns up upon re-entry into the Earth's atmosphere or they reach their extraterrestrial destinations.
What happens if someone dies in space?
10 seconds of exposure to the vacuum of space would force the water in their skin and blood to vaporize, while their body expanded outward like a balloon being filled with air.
Their lungs would collapse, and after 30 seconds they would be paralyzed—if they weren't already dead by this point.
