The most recent spacecraft telemetry confirms the Cassini spacecraft is
in an excellent state of health and is operating normally. Cassini will
continue 24-hour Deep Space Network coverage in support of the Radio
Science Subsystem Solar Conjunction Experiment until its conclusion on
July 7th. Information on the present position and speed of the Cassini
spacecraft may be found on the "Present Position" web page located at .

A minimum separation angle of .437 degrees was reached on Friday June

On-board activities this week included Radio and Plasma Wave Science
Subsystem (RPWS) periodic instrument maintenance, start of execution for
the second RPWS looper command, an autonomous Command and Data Subsystem
(CDS) solid state recorder memory load partition repair, completion of
uplink of Radio Frequency Subsystem (RFS) conjunction test commands, and
uplink of a command to clear the CDS library command error logs as a
result of expected accumulation of log entries during the RFS
conjunction test uplinks.

The 28th Project Science Group meeting is being held this week in
Lisbon, Portugal.

Frame kernel version 34, and version 9 of the Cassini Infrared
Spectrometer (CIRS) instrument kernel were delivered to the Mission
Sequence Subsystem for inclusion in software version D8.0.1. The frame
kernel includes calibra3boresights for the Ultraviolet Imaging
Spectrograph Subsystem, CIRS, Visual and Infrared Mapping Spectrometer
Subsystem, Imaging Science Subsystem, and the high gain antenna. The
CIRS field of view was redefined in the instrument kernel.

The Spacecraft Office has identified the final inputs for system fault
protection to be uplinked with CDS flight software version 9 in the
spring of 2003.

Delivery review meetings were held for Mission Sequence Subsystem D8.0.1
and the AACS C-Kernel Generation Tool.
