CONTOUR
Spacecraft Moved to Goddard for Prelaunch Testing
1/29/02
The
spacecraft set to provide the closest look ever at a comet
nucleus was shipped today from The Johns Hopkins University
Applied Physics Laboratory (APL) in Laurel, Maryland - where
it was designed and built - to NASA's Goddard Space Flight
Center in Greenbelt, Maryland, for its next round of prelaunch
testing.
Scheduled
to launch July 1 from Cape Canaveral Air Force Station, Florida,
the Comet Nucleus Tour (CONTOUR) spacecraft spent the past
10 days in an APL vibration test lab, where engineers checked
the structural integrity of the eight-sided, 6-by-6 foot craft
aboard a large shake table.

"The
vibration tests at APL went very well," says CONTOUR Project
Manager Mary C. Chiu of APL. "The spacecraft is in great shape,
and we're ready to move on to the next stage."
At
Goddard the spacecraft will undergo spin tests; acoustic tests,
designed to simulate the noise-induced vibrations of launch;
and thermal vacuum tests, which replicate the harsh conditions
of deep space. In late April, CONTOUR will be transported
to Kennedy Space Center/Cape Canaveral and prepared for launch
aboard a three-stage, Boeing Delta II launch vehicle.
"By
the time CONTOUR launches it will have been thoroughly tested,"
says Michael J. Colby, CONTOUR lead integration and test engineer
at APL. "You have to be extremely confident that the spacecraft
will be OK when it's mounted on that Delta."
