STS-51C

40 Years Ago: STS-51C, the First Dedicated Department of Defense Shuttle Mission

On Jan. 24, 1985, space shuttle Discovery took off from NASA’s Kennedy Space Center (KSC) in Florida on STS-51C, the first space shuttle mission entirely dedicated to the Department of Defense (DOD). As such, many of the details of the flight remain classified.
