STS 41-G was the 13th flight of NASA's Space Shuttle program and the sixth flight of Space Shuttle Challenger. Challenger launched on 5 October 1984, and conducted the second shuttle landing at Kennedy Space Center on 13 October. It was the first shuttle mission to carry a crew of seven, including the first crew with two women (Sally Ride and Kathryn Sullivan), the first American EVA involving a woman (Sullivan), and the first Canadian astronaut (Marc Garneau).
The Lion Brothers version of the STS-41G patch is distinct in the use of capitalized letters for the crew names. The official version is one of only a few shuttle crew patches that uses lower case letters. Single piece construction.
