STS-51-L PATCH T-Shirt

STS-51-L was the 25th mission of the United States Space Shuttle program, the program to carry out routine transportation for Earth-to-orbit crew and cargo; as well as the final flight of Space Shuttle Challenger. Planned as the first Teacher in Space Project in addition to observing Halley's Comet for six days, the mission never flew past orbit; a structural failure during its ascent phase 73 seconds after launch from Kennedy Space Centre Launch Complex 39 on January 28, 1986, killed all seven crew members—Commander Dick Scobee, Pilot Michael J. Smith, Mission Specialists Ellison S. Onizuka, Judith A. Resnik and Ronald E. McNair, and Payload Specialists Gregory Jarvis and Christa McAuliffe—and destroyed the orbiter.
