In a covert operation back in 2012, NASA launched a morgue into orbit without any public announcement. The Human Remains Containment Unit (HRCU) was discreetly sent to the International Space Station (ISS) in a cargo shipment, hidden among supplies like freeze-dried meals and scientific equipment. While it may have appeared to be a regular shipping bag to the untrained eye, to NASA, it represented a significant step forward in preparing for death beyond Earth.
As a forensic pathologist and a long-time applicant to NASA’s astronaut program, the idea of death in space has become a haunting question for me. What would happen if an astronaut were to pass away in space? Would their remains be brought back to Earth, left behind, or sent off into the cosmos? These are questions that NASA has begun to address, recognizing that the likelihood of a space-related fatality is no longer a matter of if, but when.
The average age of NASA’s astronaut corps is around 50, and with missions extending beyond low-Earth orbit, the risk of natural deaths occurring in space has become a statistical reality. In response, NASA has taken proactive measures, such as extending astronaut selection cycles to attract younger crew members capable of handling long-duration missions.
If a death were to occur aboard the ISS today, the body would be placed in the HRCU, a specially designed body bag that integrates with refrigeration systems on the station to slow decomposition. Cadaver tests conducted on Earth have shown the system to be durable, but its effectiveness in true microgravity remains unknown.
NASA has also developed protocols for handling deaths outside the station, including on spacewalks, the moon, or deep space missions. In the event of a fatality, the body would be wrapped in a space shroud to preserve dignity and prevent contamination.
While NASA has made strides in preparing for astronautical death, there are still many unanswered questions, particularly regarding jurisdiction over deaths and mortal remains in space. As missions venture farther into the cosmos, new rules and agreements will need to be established to govern behavior in space and address the complexities of death beyond Earth.
Ultimately, as more people venture into space and the frontier expands to longer voyages and distant destinations, the inevitability of death in space becomes a statistical certainty. How we respond to these challenges will not only test our systems and ethics but also define what it means to be human in the vast expanse of space.
