Cassini Significant Event Report
For Week Ending 01/14/00
The most recent spacecraft telemetry data was acquired from the Canberra
tracking station on Tuesday, 01/11. The Cassini spacecraft is in an
excellent state of health and is operating normally. Activities on board
the spacecraft include a playback of CDA (Cosmic Dust Analyzer) data, three
SSR pointer resets and an SSR Memory Load Partition Maintenance. The speed of the spacecraft can be viewed on the "Where is Cassini Now?" web page (http://saturn.jpl.nasa.gov/operations/present-position.cfm)
The Final Sequence Integration & Validation approval meeting for the C18
sequence was held Wednesday, 01/12. The sequence has been approved and
will be radiated to the spacecraft Thursday, 01/13 with execution beginning
Sunday, 01/16.
Updates have begun for the Cassini Mission Plan to reflect activities
accepted for the Instrument Checkout - 2 Subphase. ICO-2 covers the period
from May 6 to Nov. 5, 2000, just before the spacecraft encounters Jupiter
on its way to Saturn.
A Titan Orbiter Science Team (TOST) meeting was held on January 6, 2000
that included participants from the Cassini PSG. The purpose of this
meeting was to present the status of the TOST group effort to the Cassini
science community and get feedback. The meeting went well and some key
issues were brought to the attention of the TOST members.
An Orbiter Science Operations Working Team (OSOWT) telecon was held on
Thursday, January 6, 200 to continue the science integration process for
the Jupiter Subphase. This telecon was focused on the period from -19day
to -10days from Jupiter closest approach. A proposed timeline was
developed and discussed with action assigned to the PI/TLs to address at
the upcoming Jupiter Workshop on January 24, 2000.
System Engineering distributed the 16-day orbit scenario for Flight Team
review. This scenario overlays all the operations processes that will be
conducted during the Tour for the stressful 16-day orbit time period.
Additional information about Cassini-Huygens is online at http://saturn.jpl.nasa.gov.
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.
