The first direct ascent trajectory for space shuttle. Using the manned maneuvering unit, astronauts replaced the altitude control system and coronagraph/polarimeter electronics box in the Solar Max satellite while it remained in orbit. The Long Duration Exposure Facility (LDEF) was deployed, carrying 57 experiments which were left on orbit with an intention of retrieving them during a later mission. Other payloads on this mission were: IMAX camera; Radiation Monitoring Equipment (RME); Cinema 360; Shuttle Student Involvement Program (SSlP) experiment. Show more
