STS-41-C was NASA's 11th Space Shuttle mission, and the fifth mission of Space Shuttle Challenger. The launch, which took place on 6 April 1984, was the first direct ascent trajectory for a shuttle mission. STS-41-C was extended one day due to problems capturing the Solar Maximum Mission ("Solar Max") satellite, and the landing on 13 April took place at Edwards Air Force Base, instead of at Kennedy Space Center as had been planned. The flight was originally numbered STS-13. "James D. A. van Hoften", NASA Johnson Space Center Oral History Project, 5 December 2007. "Terry J.
