That would be January 28, 1986.
Sally Ride was not on the crew of the shuttle that exploded. Two women, Christa McCauliffe and Ms Resnik (sp) were. Check keywords Challenger explosion for more information.

Challengers last flight occurred on January 28, 1986 at 11:39 a.m. EST (16:39 UTC).
The Space Shuttle Columbia disaster happened on February 1, 2003.
Challenger, U.S. space shuttle. It exploded (Jan. 28, 1986) 73 seconds into its tenth flight, killing all seven crew members, including the first civilian in space, schoolteacher Christa McAuliffe. The disaster was caused by the faulty design of a gasket (the O-ring seal). As dramatically demonstrated by Richard http://www.answers.com/topic/richard-feynman, a member of the presidential commission appointed to investigate the accident, the elastic O-ring did not respond as expected because of the cold temperature (30°F/-1°C) at launch time. (At a news conference, Feynman illustrated the loss of elasticity by dropping an O-ring into a glass of cold water.) As a result of the explosion, the United States did not send astronauts into space for almost three years as the National Aeronautics and Space Administration redesigned a number of features of the space shuttle.

Space travel and space launching is a very dangerous adventure, and as such, has many crashes. The Challenger explosion, which is one of the worst, was on January 28, 1986.
