The criteria for determining who has achieved human spaceflight varies. The Fdration Aronautique Internationale defines the cosmic threshold as any flight above the Krmn line 62 miles (100km), a definition recognised by every country, except the US Department of Defense in the 1960s. As of September 26, 2019, 565 people from 38 countries have boldly gone to space.<\/p>\n
The last half-century has witnessed the death of about 30 astronauts and cosmonauts while training or attempting dangerous space missions.<\/p>\n
However, the overwhelming majority of these deaths occurred either on the ground or technically within Earths atmosphere.<\/p>\n
Of the 550 people who have ventured into space, only three have actually died there.<\/p>\n
The first space station to park itself above Earths atmosphere was the (then) USSRs Salyut 1, which launched without a crew on April 19, 1971.<\/p>\n

Only a few days later, a crew of three Soviets launched aboard Soyuz 10 intent on entering the space station and remaining in orbit for a month.<\/p>\n
Though the Soyuz 10 crew managed to safely dock with Salyut 1, issues with the entry hatch prevented them from entering the space station.<\/p>\n
The USSR made another attempt at accessing the space station a few months later, on June 6, on the Soyuz 11 mission.<\/p>\n
Unlike the previous crew, the three Soyuz 11 cosmonauts Georgi Dobrovolski, Vladislav Volkov and Viktor Patsayev successfully entered Salyut 1.<\/p>\n
Once orbiting Earth, the trio spent the following three weeks not only setting a new record for the longest time spent in space, but conducting many of scientific experiments focused on how the body deals with extended periods of weightlessness.<\/p>\n
On June 29, the three cosmonauts returned to Soyuz 11 to began their descent to Earth.<\/p>\n
To those on the ground, everything about Soyuz 11s reentry seemed to go off without a hitch.<\/p>\n
The spacecraft appeared to make it through the atmosphere just fine, ultimately landing in Kazakhstan as planned.<\/p>\n
However, it was not until recovery crews reached the spacecraft they discovered all three crew members were dead.<\/p>\n
On opening the hatch, they found all three men in their couches, motionless, with dark-blue patches on their faces and trails of blood from their noses and ears.<\/p>\n
They removed them from the descent module. Dobrovolski was still warm.<\/p>\n
Based on the doctors reports, the cause of death was suffocation.<\/p>\n
