Christa McAuliffe probable the O-rings had not provided a proper seal. Barbara Radding Morgan, her backup, became a professional astronaut in January 1998, and flew on Space Shuttle mission STS-118, to the International Space Station, on August 8, 2007, aboard "Endeavour", the orbiter that replaced "Challenger". McAuliffe was buried at Blossom Hill Cemetery in her hometown, Concord. She has since been honored at many events, including the Daytona 500 NASCAR race in 1986. The McAuliffe-Shepard Discovery Center in Concord and the Christa Corrigan McAuliffe Center for Education and Teaching Excellence at Framingham State University are named in her memory, as are the
Christa McAuliffe asteroid 3352 McAuliffe, the crater McAuliffe on the Moon, and a crater on the planet Venus, which was named McAuliffe by the Soviet Union. Approximately 40 schools around the world have been named after her, including the Christa McAuliffe Space Education Center in Pleasant Grove, Utah. Scholarships and other events have also been established in her memory. The Christa McAuliffe Technology Conference has been held in Nashua, New Hampshire, every year since 1986, and is devoted to the use of technology in all aspects of education.
