33 years ago today, NASA lost seven crewmembers on the Shuttle Challenger. President Ronald Reagan said that day, “The crew of the Space Shuttle Challenger honored us by the manner in which they lived their lives. We will never forget them.” Today, the NASA family remembers the crew and we honor their sacrifice to further the cause of human exploration in space.
