Q:

How many astronauts have died in space?

A:

Only three people have actually died in outer space, as of 2014. During the 1971 flight of the Soyuz 11, three Soviet cosmonauts died when a ventilation valve ruptured, asphyxiating the crew and exposing them to the vacuum of space.

The disasters that destroyed the Challenger and the Columbia space shuttles both occurred inside the Earth's atmosphere. Challenger exploded 73 seconds after lift-off, while Columbia broke apart on re-entry. The 1967 fire that killed the three-man crew of Apollo 1 took place during a ground test of the command module.

The first in-flight fatality on a space mission occurred when the Soyuz 1 capsule crashed in 1967. The descent module, carrying cosmonaut Vladimir Komarov, crashed due to a parachute malfunction.

  • Q:

    Why do astronauts wear space suits?

    A:

    The purpose of a space suit is to keep astronauts alive in outer space, as the extreme temperatures and lack of an atmosphere mean instant death for a human. Astronauts also wear suits inside the spacecraft sometimes in case cabin pressure drops suddenly, and they wear them when they are performing work on the exterior of the space ship.
