STARDUST Status Report
June 2, 2000
There were eight Deep Space Network
(DSN) tracking passes during the past week. All subsystems onboard the spacecraft
are performing normally.
Trajectory Correction Maneuver #3 (TCM-3) was successfully executed
last week, and provided a velocity change of 1.869 meters/second.
An attempt was made to maintain carrier lock on the downlink signal from
the spacecraft during the maneuver. Even though the maneuver attitude was
at the edge of the Medium Gain Antenna's (MGA) beam width, the DSN was
unable to detect the carrier signal.
There will be two additional TCMs prior to the Comet Wild-2 encounter in
2004 to control the spacecraft flyby distance. These TCMs will be executed
with the Sample Return Capsule
(SRC) heat shield in the open position since
the Aerogel collector will be deployed for dust collection at the comet
encounter. The heat shield was open during TCM-3, successfully
demonstrating that TCMs can be performed in this configuration.
After TCM-3 the SRC heat shield was successfully returned to its cruise
position (unlocked). The SRC will remain in this configuration until
July 2001 when the next interstellar dust collection period begins.
Twenty-eight Navigation Camera images were successfully taken with 21
of the 28 images played back over a 70 meter DSN station. The remaining
images will be downlinked over the next month. These images will provide
additional data on the camera's sensitivity.
