STARDUST Status Report
September 3, 1999
The spacecraft continues to perform nominally in cruise sequence SC008.
The spacecraft is currently 1.7 AU from the Earth and 1.9 AU from the Sun.
The spacecraft is approaching the range from Earth where the Deep Space
Network (DSN) 34 meter Beam Waveguide (BWG) antennae can be used for
commanding reliably. STARDUST will soon concentrate on using the DSN
34 meter High Efficiency (HEF) antennae almost exclusively until the
spacecraft comes within 2.0 AU from Earth later next year.
The flight team at Lockheed Martin Astronautics (LMA) has successfully
commanded the Payload and Attitude Control Interface (PACI) Board reset
fix and the next cruise sequence SC009. The PACI Board will now reset
properly, not causing the spacecraft to go into safe mode as it had on 2
occasions when a sun sensor read error occurred which caused an interrupt
leading to an incorrect reset.
It was decided to forego Trajectory Correction Maneuver A (TCM-A) in order
to continue to progress on the All Stellar command testing and implementation
and to begin payload testing and observations again. There were too many
activities after responding to the 2 safe modes during the last month and
the Mars Surveyor 98 spacecraft are nearing Mars, taking additional attention
from the LMA flight team, as planned. TCM-A will be accommodated in the
Deep Space Maneuver (DSM-1).
