STARDUST MISSION STATUS
February 7, 1999
NASA's Stardust spacecraft successfully shot into a clear
blue sky atop a Delta II rocket from Florida's Cape Canaveral Air
Station at 4:04:15 p.m. EST (1:04:15 p.m. PST) today to become
the first U.S. mission destined for a comet, and the first-ever
spacecraft sent to bring a sample of a comet sample back to
Earth.
The Stardust team reported that the spacecraft was in
excellent health and that its power and temperature levels are
normal. The spacecraft is in communication with NASA's Deep
Space Network, and is controlled through the mission operations
area at Lockheed Martin Astronautics, Denver, Colo., and
monitored at NASA's Jet Propulsion Laboratory, Pasadena, Calif.,
where the mission is managed.
Sixty-six seconds after liftoff, the four solid rocket
motors on the Delta were discarded and the first stage continued
to burn until it shut down and fell away about 4 minutes, 30
seconds into the mission. A few seconds later, the Delta's
second stage ignited and burned for about 5 minutes, cutting off
at 9 minutes, 55 seconds into the mission. Almost immediately
after the second-stage ignition, the fairing or nose-cone
enclosure around the Stardust spacecraft was jettisoned.
After coasting for about 11 minutes, the second-stage engine
restarted and burned for about 2 minutes. The third stage
separated from the second stage 24 minutes, 27 seconds into the
mission; the Star 37 third stage ignited 25 minutes, 4 seconds
into the mission, burning for about 2 minutes. At 27 minutes, 19
seconds into the mission -- or 4:31:34 p.m. EST -- the Stardust
spacecraft separated from the Delta's third stage, stopping its
spinning by firing onboard thrusters. About 4 minutes after
separation, Stardust's solar arrays began to unfold and pointed
toward the Sun. The spacecraft's signal was successfully
acquired by the NASA Deep Space Network complex in Canberra,
Australia, 51 minutes after launch at 4:55 p.m. EST.
Stardust is on a flight path that will deliver it to Comet
Wild-2 (pronounced "Vilt-2" on January 2, 2004. The spacecraft
will gather particles flying off the nucleus of the comet. In
addition, Stardust will attempt to gather samples from a stream
of interstellar dust that flows through the solar system.
Captured in a glass foam called aerogel, the comet and
interstellar dust samples will be enclosed in a clamshell-like
capsule that will be dropped off for reentry into Earth's
atmosphere in January 2006. Equipped with parachutes, the
capsule will float to a pre-selected spot in the Utah desert,
where it will be retrieved and its contents delivered to
scientists for detailed analysis.
