Mission Status 2010
Tim Larson Stardust Spacecraft Team
March 31, 2010
The spacecraft is in cruise mode and all subsystems are operating as expected. The science and spacecraft team concluded three days of meetings reviewing the detailed comet encounter timeline and finalizing decisions and trade-offs that will be included in the design of the encounter sequence. The side A EEPROM has been updated to include a large software patch that enables nucleus tracking during the comet Tempel 1 flyby. This will free up space in the CMIC memory to write files needed for autonomous imaging restart capability during the flyby.

All spacecraft subsystems are operating nominally. The spacecraft and science teams are meeting this week to finalize details of the Tempel-1 encounter science and spacecraft activities. This will lead to detailed design of the sequences and commencing the test program. The project has received approval from LM and JPL senior management to proceed with a spacecraft side swap to mitigate the risk posed by the degrading IMU on the primary side. The swap is currently planned for May 3, followed by a detailed checkout and characterization of the side B components.
March 17, 2010
The spacecraft is healthy and operating as expected. No major activities are planned on board in the near term.
March 10, 2010
The spacecraft continues to operate nominally. The project has accepted the recommendation of the navigation team and has postponed TCM-29, originally planned for March 17, until late May to reduce uncertainties in the OD and resulting maneuver.
March 3, 2010
The spacecraft is healthy and functioning nominally.
February 24, 2010
The spacecraft is healthy and functioning nominally after the TCM 28 maneuver.
February 17, 2010
The spacecraft successfully executed a 24 m/sec maneuver today, February 17. The little over 23 minute burn of the TCM thrusters was performed to delay the spacecraft's arrival at comet Tempel 1 in February 2011 by a little over 8 hours. This adjustment, based on predictions of the phase of the comet at arrival, will help optimize the view of the comet as the spacecraft flies by, providing overlapping coverage of areas previously imaged by the Deep Impact spacecraft and new territory, expanding the knowledge of the comet nucleus.
