Missions

STS-51-C

The mission was the first shuttle flight dedicated to the Department of Defense (DoD), and most information about it remains classified. For the first time, NASA did not provide pre-launch commentary to the public until nine minutes before liftoff. The Air Force only stated that the shuttle successfully launched its payload with an Inertial Upper Stage on the mission's seventh orbit. It is believed that the payload was a Magnum/ORION ELINT satellite.
