STARDUST Status Report
March 6, 1998
STARDUST Project Manager
The Assembly, Test, and Launch Operations (ATLO) activities continued
to make progress. The Telecom subsystem interface tests with the system
were completed; work proceeded on commanding with the ground support equipment,
and testing of compatibility with the Deep Space Network (DSN) was initiated.
The assembly of the flight Sample Return Capsule (SRC) is nearing completion.
The avionics package was installed. And ballast was added to increase the
entry stability margin. This brings the capsule to 45 kg.
The Inertial Measurement Unit (IMU ) chassis seal review and assessment
of the torque of the connector screws was completed. This resulted in agreement
to proceed with installation of electronics for the leak test.
A redesign of the field-programmable gate array (FPGA) interface to the
Cometary and Interstellar Dust Analyzer (CIDA) was completed. The CIDA electronic
simulator box arrives today from Germany to support validatation testing.
Thermal vacuum testing of the spacecraft test battery was completed indicating
acceptable temperature gradients. Random vibration with control on the test
battery was also completed and qualified the composite bulkheads.
In other news, Ambient temperature solar array deployment tests were completed
on the qualification unit. Electromagnetic testing was completed on the
Power Control Assembly (PCA). Random vibration and 2 axes of shock testing
of the flight computer has been completed. And the Block Dictionary and
Flight Rules and Constraints were published.
