Cassini Significant Event Report
For Week Ending 06/02/00
The most recent spacecraft telemetry data was acquired from the Madrid
tracking station on Wednesday, 5/31. 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.
Activities this week included a reaction wheel momentum unload, SSR memory
load partition repair, and upload of the Magnetospheric Imaging Instrument
(MIMI), Visual and Infrared Mapping Spectrometer (VIMS) and Cassini Plasma
Spectrometer (CAPS) flight software. All instrument flight software has
now been successfully uplinked to the solid state recorder. Instrument flight
software checkout will begin next week.
Program approval was given for the Jupiter Science Phase F portion of the
Jupiter Subphase. Phase F covers the period from +15 days from Jupiter
closest approach to +72 days. The Science Planning Virtual Team (SPVT) will
now begin implementation of Phase F.
The VIMS Fomalhaut observations have been approved for inclusion in
Instrument Checkout 2 (ICO2) and will occur in the C22 sequence.
A Satellite Orbiter Science Team (SOST) meeting was held to continue to
work on the allocation of time and resources to the instrument teams for
the icy satellite flybys. This meeting focused on working the integration
issues for the Dione flyby, and integration issues associated with the 3
The Automated Command Number Assignment tool was made delivered to
operations this week.
Cassini outreach participated at a home schooling convention held at the
Ontario Christian High School.
All Cassini teams participated in an Independent Cost Review requested by

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.
