Space exploration is one of humanity’s greatest achievements, but it also involves considerable risks. NASA astronauts, while highly trained and prepared for almost any challenge, must also plan for the unthinkable: what happens if an astronaut dies in space? This is a difficult but crucial part of mission planning. Astronauts face dangerous environments where survival can depend on their training, technology, and the decisions they make in split seconds.
NASA Astronaut Mortality Protocols for Space Missions
NASA astronauts are trained for many types of emergencies, including the possibility of an astronaut dying during a mission. According to Hadfield, astronauts go through “death simulations” that simulate extreme scenarios like asteroid impacts or the Earth stopping its rotation. This type of training is essential for handling a range of potential risks in space.
How NASA Astronauts Handle Death During Extravehicular Activity (EVA)
If a NASA astronaut were to die while outside the International Space Station on an extravehicular activity (EVA), the immediate response would be to bring the astronaut’s body inside the airlock. Hadfield explained that, if possible, the astronaut’s body would remain inside the pressurized suit. The reason for this is simple but vital: the body decomposes faster in space, and the presence of any decomposition byproducts could create a biohazard in the tightly controlled atmosphere of a spacecraft.
Storing the Body of a Deceased Astronaut in Space

Once inside the airlock, the deceased astronaut’s body would be temporarily stored in a cooler area of the ISS, which would help prevent any further decomposition. NASA’s guidance directs the crew to carefully determine the next steps for the remains’ final disposition. These options include returning the remains to Earth, launching them on a disposal trajectory, or allowing them to burn up during re-entry into the Earth’s atmosphere.
Safety First: Protecting the Remaining Crew
NASA’s main concern following the death of an astronaut in space is the safety of the remaining crew members. After a death occurs, the decomposition of the body would quickly create a biohazard, particularly in the closed atmosphere of a spacecraft. NASA guidance stresses that the health of the surviving astronauts must be prioritized, as decomposition can release pathogens and harmful gases that could compromise the integrity of the space station or spacecraft.
The Complexities of Decomposition in Space for NASA Astronauts
The enclosed environment of the ISS makes it particularly critical that these risks are minimized. The byproducts of decomposition, such as gases and pathogens, could endanger everyone aboard. The surviving crew’s health requires careful monitoring of the space station’s air quality and living space integrity.
The Psychological and Ethical Aspects of Death in Space
Space astronautical death protocols combine physical protection along with moral and psychological coverage for crewmembers’ experiences with losing their colleagues at deep space locations. NASA guidance requires conducting procedures while preserving complete respect and dignity toward the deceased astronaut. Professional conduct remains essential for surviving astronauts who need to execute procedures by designed protocols while demonstrating respect to their departed colleagues.

NASA understands that dealing with death on space missions would present significant psychological challenges to astronaut crews. NASA provides emotional and physical support to surviving crew members to assist them after a death in space. Spaceflight training prepares astronauts to handle technical challenges and emotional trauma from severe post-accident psychological impact.
Space Exploration: A New Frontier for NASA Astronauts and Humanity
NASA astronauts represent the pinnacle of human curiosity and resilience. They explore the final frontier on behalf of all of us, knowing that space travel is fraught with risk, including the possibility of death. However, NASA prioritizes crew safety by implementing protocols for every scenario, including the death of an astronaut.
The Pandora mission showcases NASA’s efforts to push the boundaries of space exploration and uncover alien mysteries. This mission brings humanity closer to unlocking the mysteries of alien life. Learn more about this mission in our article on NASA’s Pandora Mission: Closer to Unlocking Alien Secrets.
The Ultimate Goal of Human Space Exploration
NASA astronauts display human courage while retaining adaptability until death despite receiving specialized training to manage spaceflight death. Space explorers journey to uncharted territories while keeping spacecraft crews protected from the imaginable dangers they encounter.
NASA has framed robust safety protocols and protocols that enable responsible management of these potential space tragedies. NASA prioritizes astronaut health, safety, and proper handling through “death simulations” as part of its protocols. The lessons from extreme space exploration scenarios will serve future generations of astronauts by improving the safety of interplanetary travel.
Understanding NASA’s space emergency procedures is crucial for anyone pursuing a career in space exploration or spaceflight.
