here's no doubt space is an extremely dangerous place, but only a handful of space travelers have actually died there.

For many wannabe astronauts, the idea of venturing into the great unknown would be a dream come true. But over the past 50 years, there’s been a slew of spaceflight-related tragedies that are more akin to an astronaut’s worst nightmare.

In the last half-century, about 30 astronauts and cosmonauts have died while training for or attempting dangerous space missions. But the vast majority of these deaths occurred either on the ground or in Earth’s atmosphere — below the accepted boundary of space called the Kármán line, which begins at an altitude of about 62 miles (100 kilometers).

However, of the roughly 550 people who have so far ventured into space, only three have actually died there.


Citar
As a direct result of the decompression deaths of the Soyuz 11 crew, the USSR quickly made the shift to requiring all cosmonauts to wear pressurized space suits during reentry — a practice that’s still in place today.
