Cassini Significant Event Report
For Week Ending 09/08/00
The most recent spacecraft telemetry was acquired from the Madrid tracking
station on Wednesday, 09/06. The Cassini spacecraft is in an excellent
state of health and is operating normally. The speed of the spacecraft can be viewed on the "Where is Cassini Now?" web page.
A mini-sequence to power on the Cosmic Dust Analyzer (CDA), Imaging Science
Subsystem (ISS), Magnetometer Subsystem (MAG), Magnetospheric Imaging
Instrument (MIMI), Radio and Plasma Wave Science (RPWS), Ultraviolet Imaging
Spectrometer (UVIS) and Visual and Infrared Mapping Spectrometer (VIMS) was
uplinked and executed successfully. The instruments had previously been
powered off to accomodate the recently completed CDS flight software load
and checkout. Uplink of some modules was the last activity for Cruise 21.
The Cruise 22 background sequence will be uplinked later this week.
Final Sequence products and SEG products for Cruise 22 were delivered as
scheduled. The package for the Final Approval meeting was sent to Sequence
Virtual Team members for review. The subsequence generation process for
C23 has concluded with the receipt of all subsequence generation input
products. Version 9 of the Saturn Orbit Insertion (SOI) Sequence was
delivered to the Integrated Test Lab (ITL) for testing.
The Multi Mission Image Processing Laboratory (MIPL) delivered the final
versions of the Level 1A product generation program and the uplink
software including Instrument Expanded Block (IEB) generation programs for
VIMS. Both software sets are integrated with the multi-mission database,
automated file delivery system, and the product display capability. MIPL
also completed a hardware reconfiguration to support Jupiter (memory
upgrades and movement of platforms to faster networks).
User Acceptance Testing (UAT) of TC&DM V25.2 software is progressing well
and no significant issues or concerns have been found.
Mission Planning made a presentation to the Cassini Design Team on
Post-Jupiter Deep Space Network Requirements.
Additional information about Cassini-Huygens is online at http://saturn.jpl.nasa.gov.
Cassini will begin orbiting Saturn on July 1, 2004, and release its piggybacked Huygens probe about six months later for descent through the thick atmosphere of the moon Titan. Cassini-Huygens is a cooperative mission of NASA, the European Space Agency and the Italian Space Agency. JPL, a division of the California Institute of Technology in Pasadena, manages the mission for NASA's Office of Space Science, Washington, D.C.
