NASA's Deep Impact mission is the subject of a pre- launch mission and science news media briefing at 1 p.m. EST, Tuesday, Dec. 14 in the NASA Headquarters Webb auditorium, 300 E St. S.W., Washington.
Planned liftoff for the mission is Jan. 8, 2005. NASA's Deep Impact spacecraft has a six-month, 431 million kilometer (268 million mile) voyage to comet Tempel 1, where it will send a projectile crashing into the comet. The first time this has ever been attempted, the impact should create a stadium-sized crater, allowing scientists to study pristine material inside the comet dating back to the formation of our solar system.
