The most recent spacecraft telemetry data was acquired from the Goldstone tracking station on Wednesday,
01/19. The Cassini spacecraft is in an excellent state of health and is operating normally. On Thursday 01/13
the Cruise18 sequence was radiated to the spacecraft and began nominal execution on Sunday, 01/16.
Activities this week include an AACS Constraint Monitor update, SSR pointer reset, and Periodic Instrument
Maintenance. The speed of the spacecraft can be viewed on the “Where is Cassini Now?” web page

A number of technical interchange meetings occurred this week between remote and visiting Probe Team
members and the Spacecraft Office. Topics included the Engineering Change Requests for Instrument Checkout
2 (ICO-2) and the Probe Checkouts.

Version 24.6 DOM testing has been completed with no significant issues identified. The Operational Readiness
Assessment meeting is currently scheduled for 1/25. Version D7 of the Mission Sequence Subsystem was
delivered this week. This software will be used in the development of the Cruise 19 sequence.

The final Change Control Board for ICO-2 met Wednesday, 1/19. Of the 30 requests for activities, 27 have
been approved with three pending resolution of some open issues.

The final corrections have been made to the Saturn Educator Guide. This publication will go to press next
week.

The Cassini Project Science Group will assemble at JPL next week. Meetings will be held from 01/24-01/28 and
include a Jupiter Workshop to continue integration of the Jupiter Science Plan, Discipline Working Group (DWG)
meetings to discuss the issues associated with the TOST and Jupiter plans, a Cassini Science Planning Design
Workshop to discuss the process used to develop the Science plans for Tour, and a Titan Orbiter Science
Team (TOST) report. The first Surfaces Orbiter Science Team (SOST) meeting will begin discussing the science
plans for the icy satellite targeted flybys.
