The STS-31 crew launched aboard the Space Shuttle Discovery on April 24, 1990 at 8:33:51am (EDT). Included in the crew of five were Loren J. Shriver, commander; Charles F. Bolden, pilot; and Steven A. Hawley, Bruce McCandless, and Kathryn D. Sullivan, all mission specialists. STS-31 was the 35th mission of the American Space Shuttle program, which launched the Hubble Space Telescope astronomical observatory into Earth orbit. The mission used the Space Shuttle Discovery (the tenth for this orbiter), which lifted off from Launch Complex 39B from Kennedy Space Center, Florida. Discovery's crew deployed the telescope on April 25, and spent the rest of the mission tending to various scientific experiments in the shuttle's payload bay and operating a set of IMAX cameras to record the mission. Discovery's launch marked the first time since January 1986 that two Space Shuttles had been on the launch pad at the same time - Discovery on 39B and Columbia on 39A.
