This is an outstanding video with an incredibly poignant story, that you really have to see.
It's about Ronald E. McNair, who was the second African American to enter space.
McNair died 27 years ago yesterday, when the space shuttle Challenger exploded 73 seconds after takeoff. He was one of seven astronauts on board.
Ask anyone who's old enough to remember, and they can probably tell you where they were when the disaster happened.
It was a tragic reminder of how astronauts put their lives on the line, at a time when we started to see space travel as somewhat routine.
For the video, the website StoryCorps had McNair's brother Carl tell a story about when Ronald was a kid in South Carolina in the late 1950s.
It's about a segregated local library, Ronald McNair's courage to stand up for his rights, and his dream of becoming an astronaut.
