What Caused the Challenger Disaster?

Challenger Explosion Anniversary: Space shuttle disaster kills 7 in 1986

I was only a baby when the Challenger disaster happened, but I grew up hearing about the brave astronauts who were lost on that terrible day. It was the worst event NASA experienced since Apollo 13 to date and would foreshadow the loss of the Columbia crew in 2003. This being the 40-year anniversary, I thought I'd make a tribute to the Challenger crew an honor their memory. | Kyle Cherryholmes
