STS-41-G was the first Space Shuttle mission to carry a crew of seven people.
Challenger launched the mission on October 5, 1984, with commander Robert Crippen, pilot Jon McBride, mission specialists Sally Ride, Kathryn Sullivan, and David Leestma, plus payload specialists Paul Scully-Power and Marc Garneau. The flight lasted just over eight days.
The mission is sometimes confused with STS-7, which carried five people, or STS-61-A, which later carried eight—the largest Shuttle crew. STS-41-G’s seven-person crew was notable because it included two payload specialists and two women, Ride and Sullivan.
The mission focused heavily on Earth observation and atmospheric research. Its instruments included the Shuttle Imaging Radar-B and the Large Format Camera, while Sullivan and Leestma performed a spacewalk to test an orbital refueling system.
