Cassini Significant Events
for 09/05/02 - 09/11/02

The most recent spacecraft telemetry was acquired from the Goldstone
tracking station on Tuesday, September 10.  The Cassini spacecraft is in
an excellent state of health and is operating normally.  Information on
the present position and speed of the Cassini spacecraft may be found on
the "Present Position" web page located at
http://saturn.jpl.nasa.gov/cassini/english/where/ .

On-board activities this week included Radio and Plasma Wave Science
High Frequency Receiver calibrations, a Composite InfraRed Spectrometer
functional test and power-off, clearing of the ACS high water marks,
uplink of the Probe Checkout (PCO) mini-sequence, and Solid State Power
Switch trip algorithm enable/disable in support of PCO.

Proposed changes to the C34 preliminary sequence integration and
validation products were distributed to the Sequence team.  Review
comments have been  received and incorporated into the package for next
week's preliminary approval meeting.

Multi-mission Image Processing Laboratory personnel met with
representatives from the Planetary Data System (PDS), and Instrument
Operations archiving to resolve issues relating to Level 1A product
labeling, compliance with PDS standards, and Science Archive Working
Group plans.

ACS delivered Flight Software version A8.6.3 for testing.  This is
expected to be the last version change for ACS A8.

The Spacecraft Operations Office completed a Project Review for ACS and
CDS Flight Software in-flight checkout.  DSN tracking requests for the
February - April '03 timeframe are currently being negotiated.

A Delivery Coordination Meeting was held to release the PC version of
the Science Opportunity Analyzer (SOA) tool.   With the exception of
Opportunity Search and APGEN communication, this version of SOA provides
the same functionality, and limitations, of the Solaris release. Support
for Opportunity Search on PCs is being pursued.  There are no plans to
include APGEN communication. Co-Is will be able to download the software
from the Cassini Web server.

Personnel from System Engineering and Mission Support and Services
Office participated in a review of Navigation hardware requirements.
The NAV team is in an evaluation phase with a goal of selecting and
procuring an acceptable architecture/platform by early second quarter of
FY03 to support tour operations.

The NASA educational poster "Unveiling the Myth of Saturn" is available
on NASA Spacelink.  The poster cover is a depiction of the mythological
story of Saturn combined with images of space-age exploration.
Additional resources include information about the Cassini mission to
Saturn, names and stories about the mythological god Saturn, and a
classroom activity for students in grades 4-8. "Unveiling the Myth of
Saturn" is located at:

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.
