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.Continue Reading
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 life support system installed in the space station helps astronauts live in space for extended periods of time. While in space, the life support system provides oxygen and filters out the carbon dioxide exhaled by the astronauts. In addition, astronauts go through rigorous training regimens to ensure that their bodies can handle the conditions.Full Answer >
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.Full Answer >
The survival needs of astronauts in space depend on the amount of time in question, but for standard, short missions, they require protection against the frigid temperatures and protection from solar glare and the vacuum. These needs are particularly pressing during spacewalks, when astronauts are outside their ships. As explained by NASA, spacesuits are sophisticated protective garments with oxygen tanks, carbon dioxide scrubbers, active fingertip heaters and other protective measures.Full Answer >
NASA beams live and recorded video content into low-earth orbit, allowing astronauts to watch live video in outer space. A special broadband connection carries the video into space on an as-requested basis. Astronauts watch television and other content when they are not working.Full Answer >
