The most recent spacecraft telemetry was acquired from the Goldstone
tracking station on Monday, July 30. The Cassini spacecraft is in an
excellent state of health and is operating normally. Information on the
spacecraft’s position and speed can be viewed on the “Present Position”
web page, http://www.jpl.nasa.gov/cassini/english/where/ .

Recent spacecraft activities include two Radio and Plasma Wave Science
High Frequency Receiver calibrations and two Cassini Plasma Spectrometer
data set collections. The Composite Infrared Spectrometer was powered on
for instrument muting tests, and the second of the three muting tests was
completed this week. These tests are being conducted by the Spacecraft
Operations Office (SCO) in support of future Huygens Probe checkouts. The
SCO also completed an Attitude Control Subsystem Reaction Control
Subsystem calibration.

The Critical Design Review (CDR) for the Cassini Ground Data System (GDS)
was held, which included a system-level design overview from each office
and updates of the Cassini software inventory, subsystem interfaces, and
data flow.

In support of the C28 sequence development, the preliminary Sequence
Integration & Validation Package was created and released.

The C29 Science Planning Virtual Team (SPVT) Project Briefing was held,
with the Project approving the integrated plan for implementation. The
first product input port for this process falls within the next week, and
the entire C29 SPVT phase will be complete in early September.

Meetings of both the Magnetosphere and Cross-Discipline Target Working
Teams were held last week. Discussion included data input to the Cassini
Information Management System as well as MAPS campaigns and Saturn imaging
movies.

The last updates of the D27 Multi Mission Image Processing Laboratory
software were delivered for testing. These updates are evolutionary
updates to both Uplink and Downlink support software.

Cassini Outreach personnel gave a 3 hour presentation and demonstration of
Cassini educational resources to participants in a NASA NEWEST workshop.
The workshop was sponsored by the Educator Resource Center in Pomona,
California and attended by 30 educators from throughout the US.

Cassini is a cooperative project of NASA, the European Space Agency and
the Italian Space Agency. The Jet Propulsion Laboratory, a division of the
California Institute of Technology in Pasadena, Calif., manages the Cassini
mission for NASA’s Office of Space Science, Washington, D.C.
