FOR IMMEDIATE RELEASE
August 10, 1998
Deep Space 1, the next solar system mission to be
managed by the Jet Propulsion Laboratory, is the focus of two
free public lectures this month. The first takes place on
Thursday, August 20, at 7 p.m. in JPL's von Karman Auditorium,
and the second follows on Friday, August 21, at 7 p.m. in the
Forum at Pasadena City College. Reservations are not necessary,
and parking is free.
Deep Space 1 is the first flight of NASA's New Millennium
Program, all of whose deep space and Earth-orbiting missions are
designed to test new technologies so that they can be confidently
used on science missions of the 21st century.
The low-cost, high-risk Deep Space 1 mission will validate
such new technologies as an ion propulsion engine similar to
those described in futuristic science fiction works. The engine
is one of 12 innovative technologies to be tested during the
mission, scheduled to be launched October 15 from Cape Canaveral,
Most of the validation of Deep Space 1's technologies occurs
within two months of launch. After that the diminutive
spacecraft, reaching just 1.5 meters (4.9 feet) in height, will
continue testing its two new science instruments while flying by
a near-Earth asteroid, 1992 KD, in July 1999. The instruments
will send back visible images and infrared and ultraviolet
spectral images while the spacecraft flies closer to an asteroid
than has ever been attempted before, perhaps as low as 5
kilometers (three miles).
Deep Space 1 Chief Mission Engineer Dr. Marc Rayman will
present the illustrated talk. Rayman, whose doctorate in physics
is from the University of Colorado, combined his technical
training with his lifelong study of space exploration by joining
the JPL staff in 1986. In 1994, he helped initiate the New
Millennium Program; he has served in his current Deep Space 1
role since 1995 and will assume the title of deputy mission
manager after launch.
An overview of the Deep Space 1 mission is available on the
Internet at http://nmp.jpl.nasa.gov/ds1/ . Rayman's entertaining
New Millennium Program facts can be found at
http://spaceplace.jpl.nasa.gov/facts.htm , an educational site
for children developed by JPL in collaboration with the
International Technology Education Association.
JPL is a division of the California Institute of Technology.
This lecture is part of the monthly von Karman Lecture Series,
sponsored by the JPL Media Relations Office. A web site about the
series is located at http://www.jpl.nasa.gov/lecture/ .
