The frigid cold weather created a launch pad coated in thick ice which wrapped itself around the fully fueled space shuttle on the morning of January 28, 1986. Challenger's tenth crew, led by commander Francis Dick Scobee, included NASA's Teacher in Space representative, Sharon Christa McAuliffe, on a very publicized mission flying the first average citizen into space.
America's first "teachernaut" planned to conduct two live classroom sessions, including "The Ultimate Field Trip", a tour through the orbiter; and a lesson on why people explore and work in space from 176 miles above. The broadcasts were to be shown in classrooms around the planet on NASA-Select TV. Christa's excitement and enthusiasm made her a popular role model both in the public school systems and with the media.
This shuttle stack was the heaviest to launch weighing 4.53 million pounds, and carrying the second massive Tracking and Data Relay Satellite (TDRS). The SPARTAN satellite, designed to be placed over the side of the shuttle for a free flight close study of the popular visit by Haley's Comet, was to be deployed on day three of the mission and retrieved twenty orbits later.
