Stardust Status Report
April 20, 2001
There were two Deep Space Network (DSN) tracking passes this past
week and all subsystems are performing nominally.
The Navigation Camera successfully took another two images with the
CCD and mirror motor heaters still on. There has been no change in
the good image quality since the last set of pictures last week.
The heaters will remain on until approximately May 10.
CIDA continues to observe the interstellar dust stream with an
optimal spacecraft attitude when not in communication with the earth.
The recent solar storms have had a minimal impact on the
spacecraft's performance. The only evidence was a large number of
Star Camera outages during a two hour period. A Star Camera outage
occurs when the star image taken cannot provide a valid attitude
knowledge update. The longest outage was approximately 20 seconds.
The fault protection limit for Star Camera outages is five minutes
in All-Stellar attitude determination mode. If no valid images can
be obtained in five minutes the on-board fault protection software
will request safe mode.
The Principal Investigator, Project Manager and Mission Manager
participated in the NASA Discovery Program Retreat with all other
Discovery projects. Program status, individual project statuses and
lessons learned were discussed. The level of interaction and
information exchange between the program and projects was excellent.
The Principal Investigator and Outreach Manager participated in a
filming by The Learning Channel in the STARDUST Flight Operation,
Recovery and Command Enterprise (FORCE) room at JPL. This will be
part of a future program on comets.
