Stardust Status Report
March 15, 2002
There were two Deep Space Network (DSN) tracking passes in the past week
and all subsystems are normal. Stardust is currently 2.70 AU (251 million
miles or 404 million kilometers) from the Sun.
Analyses of the power subsystem show that, even in the worst-case scenario,
there is still extra power to recharge the battery with the current values
to protect the spacecraft in the unlikely event that the battery's charge
drops too low (80 percent safe mode entry, 75 percent side swap). These
fault protection limits will remain in place until early summer.
A flight software patch, correcting the operating system's floating point
math library function, was successfully installed as a preventative
measure. No Stardust operations have been affected by this defect; however
the patch was installed as a preventive measure to ensure that this defect
will not impact future operations.
The team is planning to gather in early April to celebrate Dr. Kenneth L.
Atkins' retirement. Ken was the original Stardust project manager, leading
the team to the successful spacecraft flight system development, launch and
early operations.
