|"After a voyage of 173 days and 431 million kilometers (268 million miles), NASA's Deep Impact spacecraft will get up-close and personal with comet Tempel 1 on July 4, 2005. The first of its kind, hyper-speed impact between space-borne iceberg and copper-fortified probe is scheduled for approximately 1:52 a.m. EDT on Independence Day. The potentially spectacular collision will be observed by the Deep Impact spacecraft, and ground and space-based observatories." Mission Challenge asks students questions related to the mission, such as "How far away will the flyby spacecraft be when the impactor hits Tempel 1?" and "How fast will the impactor spacecraft be moving when it hits Tempel 1?" Part of the Discovery Zone, created with the Jet Propulsion Laboratory (JPL) of California Institute of Technology. See also the Deep Impact site's section on Education.|
