Apollo 1 and the Space Shuttle Challenger: The History of NASA’s Two Most Notorious Disasters

As Apollo 11’s name suggests, there were actually a number of Apollo missions that came before, many of which included testing the rockets and different orbital and lunar modules in orbit. In fact, it wasn’t until Apollo 8 that a manned vehicle was sent towards the Moon and back, and before that mission, the most famous Apollo mission was Apollo 1, albeit for all the wrong reasons.

There were no delusions regarding the dangers of manned space travel, but they were brought home on January 27, 1967, when all three astronauts were killed by a fire that ignited in the cabin during a launch rehearsal. To this day, there is still debate over what ignited the fire, but the disaster made clear that the modules being used by NASA had a series of fatal flaws. After the Apollo 1 tragedy, NASA changed its plans by first running a series of unmanned missions to test the Saturn rockets and the different modules throughout 1967 and early 1968. and it would not be until Apollo 7 launched about 20 months after the disaster that NASA dared to conduct another manned mission.

On the morning of January 28, 1986, the Space Shuttle Challenger launched for the 10th time, beginning mission STS-51-L. Space shuttles had already successfully completed 24 missions, and no American spacecraft had ever failed to reach orbit during an official mission. On this mission, the Challenger was carrying a satellite for the Tracking and Data Relay Satellites system, which was to be deployed in orbit. The crew included Ronald McNair, who had already been the second African-American in space, and Ellison Onizuka, who had already been the first Asian-American astronaut in space. But the highlight of the mission was to be the “NASA Teacher in Space Project,” in which a civilian teacher would give teaching lessons to his or her class while onboard the space shuttle.
