(01/06/1999) --- A solid rocket booster is raised to a vertical position before lifting it up the mobile launch tower at Pad 17A, Cape Canaveral Air Station. It will be mated with a Boeing Delta II rocket that will carry the Stardust spacecraft into space for a close encounter with the comet Wild 2 in January 2004. Using a medium called aerogel, Stardust will capture comet particles flying off the nucleus of the comet, plus collect interstellar dust for later analysis. The collected samples will return to Earth in a sample return capsule to be jettisoned as Stardust swings by Earth in January 2006. Stardust is scheduled to be launched on Feb. 6, 1999
