NASA PREVIEWS UNIQUE DEEP IMPACT COMET MISSION 

     On July 4, NASA's Deep Impact spacecraft concludes a six-month, 268 million 
mile voyage to comet Tempel 1 by sending a projectile crashing into the cosmic 
traveler. 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. 

This daring first-of-its-kind mission is the subject of a news media briefing at 
1 p.m. EDT, Thursday, June 9, in the NASA Headquarters auditorium, 300 E St. 
S.W., Washington. 

Briefing participants:
Andrew Dantzler, NASA's Solar System Division Director, Science Mission 
Directorate
Rick Grammier, Deep Impact Project Manager, JPL
Dr. Michael A'Hearn, Deep Impact Principal Investigator, Univ. of Maryland, 
Baltimore
Dr. Don Yeomans, Deep Impact Co-Investigator, JPL

NASA TV will carry the conference live with question-and-answer capability from 
participating agency centers. Media interested in asking questions via phone 
during the briefing should call Tomeka Scales at: 202/358-0781, by noon EDT, 
Wednesday, June 8, to receive the call-in number and password. Reporters may
