* Apollo 1: During a pre-launch test on January 27, 1967, a fire ignited inside the command module, killing all three astronauts (Gus Grissom, Ed White, and Roger Chaffee). This incident was a major setback for the Apollo program and prompted significant safety improvements.
* Apollo 6: This unmanned test flight experienced multiple engine failures and a guidance system malfunction. While the spacecraft did not explode, it was considered a partial failure, leading to a delay in the program.
* Apollo 13: This mission experienced an oxygen tank explosion on April 13, 1970, while en route to the Moon. The crew (Jim Lovell, Jack Swigert, and Fred Haise) managed to survive and return safely to Earth after a complex rescue mission.
It's important to note that while these missions did not explode in the same way a rocket might, they did experience catastrophic events involving fire and explosions.
