Cassini Significant Events 08/25/10 - 08/31/10
The most recent spacecraft telemetry was acquired on Aug. 31 from the
Deep Space Network tracking complex at Madrid, Spain. The Cassini
spacecraft is in an excellent state of health and all subsystems are
operating normally. Information on the present position and speed of the
Cassini spacecraft may be found on the "Present Position" page
at:

Wednesday, Aug. 25 (DOY 237)
This week the Cosmic Dust Analyzer completed its interstellar dust
campaign. The Composite Infrared Spectrometer (CIRS) concluded a 1 day, 8
hour observation of Saturn to measure upper troposphere and tropopause
temperatures. Radio Science (RSS) performed an operational readiness test
in preparation for the occultation observation on Sept. 2. Imaging
Science (ISS) performed 15 hour observations of each of the moons
Hyrrokkin and Greip, a 23 hour observation of the moon Kiviuq, and
another observation in support of its Satellite Orbit Campaign.
Additional observations were performed by ISS and CIRS for the Titan
monitoring campaign and of faint rings at low elevation angles and high
phase angles.
Thursday, Aug. 26 (DOY 238)
Seven Instrument Expanded Block (IEB) files were uplinked to the
spacecraft and loaded to the Solid State Recorder today in support of the
S63 sequence.
The Dione Live Inertial Vector Propagator update is on board and will
execute on Sept. 3.
Friday, Aug. 27 (DOY 239)
RSS has decided to withdraw its request to change the long-term
down-times for the Canberra and Madrid 70m stations, and instead has
suggested a couple of Pre-Integrated Event (PIE) trades for the
discipline representatives in the PIE/segmentation group to evaluate.
This decision was in response to the topic that came up at the Mission
Planning Forum in early August concerning reconsideration of the Cassini
position regarding the 70m downtimes in 2013 and 2014 because of impacts
to RSS activities.
Monday, Aug. 30 (DOY 242)
Port 1 products were due today as part of the S66 Sequence
Implementation Process. The products will be merged and sent out to the
flight team for review.
The final sequence approval meeting for S63, the last sequence in the
Equinox Mission and the last sequence to use the Science and Sequence
Update Process, was held today. The S63 background sequence goes active
on Sept. 6.
Tuesday, Aug. 31 (DOY 243)
The Cassini-Huygens Analysis and Results of the Mission (CHARM)
teleconference for August was held today. The topic: "The Forces
That Sculpt Saturn¹s Rings". A PDF of the presentation package may
be obtained at:
