List of spaceflight-related accidents and incidents
This article lists verifiable spaceflight-related accidents and incidents resulting in human death or serious injury. These include incidents during flight or training for crewed space missions and testing, assembly, preparation, or flight of crewed and robotic spacecraft. Not included are accidents or incidents associated with intercontinental ballistic missile (ICBM) tests, death or injury to test animals, uncrewed space flights, rocket-powered aircraft projects of World War II, or conspiracy theories about alleged unreported Soviet space accidents.
As of January 2025[update], 19 people have died during spaceflights that crossed, or were intended to cross, the boundary of space as defined by the United States (50 miles above sea level). Astronauts have also died while training for space missions, such as the Apollo 1 launch pad fire that killed an entire crew of three. There have also been some non-astronaut deaths during spaceflight-related activities. As of 2025, more than 188 people have died in spaceflight-related incidents.
As of January 2025[update], there have been five incidents in which a spacecraft in flight suffered crew fatalities, killing a total of 15 astronauts and 4 cosmonauts.[how?] Of these, two had reached the internationally recognized edge of space when or before the incident occurred, one had reached the U.S. definition of space at 266,000 ft, and one was planned to do so. In each of these accidents, the entire crew was killed. As of December 2023[update], a total of 676 people have flown into space and 19 of them have died. This sets the current statistical fatality rate at 2.8 percent.[needs update]
NASA astronauts who died on duty are memorialized at the Space Mirror Memorial at the Kennedy Space Center Visitor Complex in Merritt Island, Florida. Cosmonauts who died on duty under the Soviet Union were generally honored by burial at the Kremlin Wall Necropolis in Moscow. No Soviet or Russian cosmonauts have died during spaceflight since 1971.
In addition to accidents during spaceflights, 11 astronauts, test pilots, and other personnel have been killed during training or tests.
Apart from actual disasters, 39 missions resulted in some very near misses and also some training accidents that nearly resulted in deaths.
Spaceflight-related accidents and incidents during assembly, testing, and preparation for flight of crewed and uncrewed spacecraft have occasionally resulted in injuries or the loss of craft since the earliest days of space programs. 35 accidents since 2009.
This list excludes deaths caused by military operations, either by deliberate detonations, or accidental during production – for example German V-2 rockets reportedly caused on average an estimated 6 deaths per operational rocket just during its production stages. Over 113 fatalities.
