In 2005, NASA commissioned Promessa, a Swedish-based company that focuses on organic burials, to advise on engineering an astro coffin. Developed by biologist Susanne Wiigh-Mäsak, the body is first moved away to prevent air pollution in the spacecraft as it decomposes.
It is then put into a Gore-Tex bag (which is water-resistant) and is exposed to Sub-Zero elements outside of the spacecraft. Once everything is completely frozen, a robotic arm rapidly vibrates the bag, turning it into a fine powder, similar to ashes after cremation.
The remains will then be freeze-dried and put into an urn-inspired contraption that is kept outside of the spacecraft.
Although this idea was created more than 15 years ago, with Promessa’s liquidation and NASA not mentioning anything else about the endeavor, it seems that this project is no more.
Astronomy.com reports that roughly 30 astronauts and cosmonauts have died while either training or attempting hazardous space missions.
The majority of those deaths either happened on the ground or within the Earth’s atmosphere.
