ou?/where?: au sol - ground
autographe?: non - noneBeskrivning : During the mission, Discovery deployed a single satellite, USA-48. Experts believe that this was a secret Magnum ELINT (ELectronic INTtelligence) satellite headed for geosynchronous orbit, similar to that launched by STS-51-C in 1985, making this mission essentially a duplicate of that earlier mission.
The satellite replaced the one launched by STS-51-C, which was running out of the maneuvering fuel required for keeping its station over the Indian Ocean.
