STS 41-C

Challenger launched from Kennedy Space Center on April 6, 1984 at 858 AM EST and landed at Edwards Air Force Base on April 13, 1984 at 5:38 AM PST. The shuttle orbited 108 times at an altitude of 313 nautical miles at an inclination of 28.5 degrees and travelled 2.9 million miles.

This mission was the first to accomplish a direct ascent trajectory. The astronauts repaired the Solar Max satellite while in orbit during a spacewalk. This was the first use of the IMAX camera, which was part of the payload. The Long Duration Exposure Facility mission was deployed with the intention of retrieval during a later mission. Other payloads on this mission were: IMAX camera; Radiation Monitoring Equipment (RME); Cinema 360; Shuttle Student Involvement Program (SSlP) experiment.

Challenger was crewed by Commander Robert L. Crippen, Pilot Francis R. Scobee, and Mission Specialists Geroge D. Nelson, James D.A. Van Hofton, and Terry J. Hart
