After the Challenger disaster, scientists spent years trying to understand why it happened, and how to prevent future disasters. Here are some of the results that came from that investigation, and how future astronauts grappled with the dangers of space exploration.
Richard Feynman, a world-renowned physicist, was asked to look into the disaster. Here is what he wrote.
The crew of the next NASA mission to launch, the Discovery, grappled with the Challenger disaster, which made the dangers of space exploration very real to them. Here is their history.
In 2004, George W. Bush awarded each member of the crew of the Challenger mission with Congressional Space Medals of Honor, including Ronald McNair.
StoryCorps is an oral history project that has collected and archived more than 45,000 interviews since 2003. Many of these stories come from people like Ronald McNair who take a stand against discrimination and achieve against great odds. Here are some other stories you can listen to:
