STARDUST Status Report
May 19, 2000
There were five Deep Space Network
(DSN) tracking passes during the past week. All subsystems onboard the spacecraft
are performing normally.
The third of three spacecraft activities to support Doppler data
measurements was performed. The DSN station successfully locked onto the
spacecraft signal and obtained two-way Doppler data. At the conclusion of
the tracking pass the DSN station tracked the carrier signal as the
spacecraft returned to its nominal cruise sun pointed attitude. The
Navigation team is analyzing the data to determine the effect of the
forces due to the thruster firings by observing the Doppler shift.
Flight sequence SC018 was successfully transmitted to the spacecraft and
will go active next week. The remainder of the DSN passes was used for
tracking purposes to support the Trajectory Correction Maneuver (TCM 3) on
Preparations for TCM 3 are continuing. The estimated size of TCM 3
is 2 meters/second or a burn time of 77 seconds.
The command files for the Navigation Camera
images have been developed and are being tested in the System Test Laboratory.
