According to Popular Science, NASA has no official policy for handling a corpse, but Hadfield said ISS training does touch on the possibility. This morbid scene would then have to be dealt with by the accompanying crew. The good news? Death by asphyxiation or decompression would happen before their body freezes, since heat leaves the body slowly in a vacuum. Within 30 seconds, their lungs would collapse and they'd be paralyzed. Within 15 seconds, they would lose consciousness. Within 10 seconds, water in their skin and blood would vaporize and their body would fill with air: Dissolved nitrogen near the skin would form bubbles, blowing them up like a dollar-store balloon to twice their normal size. Tiny meteorites could slice through their protective suits, which provide oxygen and shelter from extreme temperatures. According to Hadfield, spacewalks-a slight misnomer for the gravity-free floating that astronauts engage in outside of spacecraft-might be one potential danger. Popular Science posed this question to Chris Hadfield, the former commander of the ISS. But since it's rare to find a working astronaut in compromised health or of an advanced age, how will most potential casualties in space meet their maker? Though only 18 people have died since the emergence of intragalactic travel in the 20th century, taking more frequent risks may mean that coroners will have to list "space" as the site of death in the future. With increased opportunities comes the increased potential for misadventure.
By the 2040s, human colonists could be making the grueling journey to Mars. Professional astronauts continue to dock at the International Space Station (ISS) for scientific research. Private space travel continues to progress, with Elon Musk and Richard Branson championing civilian exploration. The coming decades should bring about a number of developments when it comes to blasting people into orbit and beyond.
