HOUSTON (CNN) — NASA’s Space Shuttle Challenger lifted off 40 years ago with an unusual crew. Even after the tragedy, family members of the Challenger astronauts wanted to carry on with a piece of their loved ones’ mission. “That’s where the idea came from,” Scobee Rodgers said in a video shared by the Challenger Center this month to mark the 40th anniversary of the tragedy. “Can we remember our loved ones by continuing their mission and make it an education mission?”The families of the Challenger crew created the Challenger Center for Space Science Education in April 1986 and opened the first center in Houston in 1988. Through those connections, something born out of a tragic accident has become a celebration of what the Challenger crew stood for, Harris added.
