Forty years ago today, the Space Shuttle Challenger exploded shortly after launch. One of the seven on board was my dear friend, Ronald McNair. As a child in Lake City, South Carolina, Ronald was barred from checking out science books at his segregated local library. Well, he eventually got his books, became the second Black American to go to space, and today that library now bears his name and serves as an education center honoring his legacy and love of science.
