Blue Origin New Glenn Explosion: on 28 May 2026, a Blue Origin New Glenn rocket exploded on the launch pad during a pre-launch engine-firing test at Launch Complex 36.
The list is about achievements in space exploration not the failures along the way.
Here's a list of catastrophes that happened along the way :
**Here is a list of the major catastrophes in human spaceflight history** (those resulting in fatalities during missions, tests, or closely related operations), starting from the beginning of the Space Age in 1957.
These are the primary incidents involving loss of life in space exploration programs (primarily NASA and Soviet/Russian). There have been 21 fatalities across five major crewed incidents.
### 1960s
- **Apollo 1 (January 27, 1967)**: A cabin fire during a ground launch rehearsal test at Cape Kennedy killed all three crew members—Virgil "Gus" Grissom, Edward White, and Roger Chaffee—due to a spark in a pure oxygen environment and design flaws (e.g., inward-opening hatch). This led to major spacecraft redesigns.
- **Soyuz 1 (April 24, 1967)**: Soviet cosmonaut Vladimir Komarov died when the spacecraft's parachute failed during re-entry, causing a crash. The mission was plagued by multiple technical issues. He was the first in-flight fatality.
- **X-15 Flight 3-65-97 (November 15, 1967)**: U.S. Air Force pilot Michael J. Adams was killed when the experimental rocket plane broke apart after control issues at high altitude (considered a spaceflight by some U.S. definitions).
### 1970s
- **Soyuz 11 (June 30, 1971)**: The only known fatalities in space itself. Cosmonauts Georgy Dobrovolsky, Viktor Patsayev, and Vladislav Volkov died from cabin depressurization due to a faulty valve after separating from the Salyut 1 space station. They were not wearing pressure suits.
### 1980s–2000s
- **Space Shuttle Challenger Disaster (January 28, 1986)**: The shuttle broke apart 73 seconds after launch due to O-ring failure in cold weather, killing all seven crew members (Francis Scobee, Michael Smith, Judith Resnik, Ellison Onizuka, Ronald McNair, Gregory Jarvis, and Christa McAuliffe). The event was broadcast live and led to a lengthy suspension of the shuttle program.
- **Space Shuttle Columbia Disaster (February 1, 2003)**: The shuttle disintegrated during re-entry over Texas due to damage from foam insulation striking the wing during launch, killing all seven crew members (Rick Husband, William McCool, Michael Anderson, Kalpana Chawla, David Brown, Laurel Clark, and Ilan Ramon). This also grounded the shuttle fleet.
### Other Notable Incidents
- **Ground/training fatalities**: Several astronauts and cosmonauts died in aircraft crashes or other pre-mission accidents (e.g., Soviet cosmonaut Valentin Bondarenko in a 1961 isolation chamber fire; various T-38 jet crashes). These are not always classified as "spaceflight" catastrophes but affected programs.
- **Launch pad/rocket explosions**: Non-crewed or ground incidents like the 1960 Nedelin catastrophe (Soviet R-16 missile explosion killing dozens, including military personnel) caused major losses but are sometimes distinguished from flight accidents.
No crewed orbital spaceflight fatalities have occurred since Columbia in 2003, thanks to improved safety protocols, though risks remain high (as seen in suborbital test flights like the 2014 Virgin Galactic SpaceShipTwo incident).
These tragedies drove critical safety improvements, such as better materials, pressure suits during critical phases, redesigned seals/hatches, and cultural shifts toward addressing known risks.
