Pictures and other scientific data from last weekend’s flyby of
comet Borrelly by NASA’s Deep Space 1 spacecraft will be unveiled at
a news conference at 1 p.m. EDT Tuesday, Sept. 25, originating from
NASA’s Jet Propulsion Laboratory (JPL), Pasadena, Calif.

The participants will be:

* Dr. Tom Morgan, Office of Space Science, NASA Headquarters,

* Dr. Marc Rayman, JPL, Deep Space 1 project manager;

* Dr. Robert Nelson, JPL, Deep Space 1 project scientist;

* Dr. Larry Soderblom, U.S. Geological Survey, Flagstaff, Ariz.,
Deep Space 1 imaging team lead;

* Dr. David Young, University of Michigan, Ann Arbor, Deep Space 1
space physics team lead;

* Dr. Donald Yeomans, JPL, manager of NASA’s Near Earth Objects
program office.

The news conference will be carried on NASA Television on the GE-2
satellite, transponder 9C, at 85 degrees west longitude, vertical
polarization, frequency 3880.0 megahertz, audio 6.8 megahertz.

Los Angeles area news media may attend the briefing at JPL’s von
Karman Auditorium, 4800 Oak Grove Drive, Pasadena. Due to heightened
security measures in place at other NASA Centers, media
representatives outside of Los Angeles can participate in tomorrow’s
briefing by calling 818/354-6666.

Saturday’s flyby of comet Borrelly was icing on the cake for Deep
Space 1, which completed its primary mission of flight-testing an
ion engine and 11 other advanced technologies two years ago. The
encounter is only the second time that spacecraft have flown past
and taken pictures of a comet.

Deep Space 1 was launched in October 1998 as part of NASA’s New
Millennium Program, which is managed by JPL for NASA’s Office of
Space Science. The California Institute of Technology in Pasadena
manages JPL for NASA.
