CASSINI SATURN MISSION, SPACECRAFT FINALIZED

     NASA's Cassini mission to Saturn has passed a major 
milestone with the completion this week of a project-wide 
critical design review.

     The review, which included a comprehensive examination 
of the mission and spacecraft, closed today at NASA's Jet 
Propulsion Laboratory, Pasadena, Calif.

     "We are very pleased with the outcome of the review and 
the status of all elements of the project," said Richard J. 
Spehalski, Cassini Project Manager at JPL.  "The design 
process is moving forward very briskly."

     In addition to JPL Cassini team members, the review 
included presentations by Dr. Hamid Hassan, European Space 
Agency Project Manager for Cassini's Huygens Titan probe and 
Dr. Romeo Pernice of the Italian Space Agency which is 
contributing Cassini's high-gain antenna and science 
instrumentation.

     In other recent activities related to Cassini, NASA 
issued letters to scientific investigators formally 
confirming the mission's experiment payload.

     The 12 experiments onboard the Cassini orbiter were 
tentatively selected in 1990, subject to evaluation during an 
"accommodation period" until the confirmation was issued.  
Another six experiments are on ESA's Huygens probe.

     Planned for launch on a Titan IV-Centaur in October 
1997, Cassini will fly by Venus twice as well as by Earth and 
Jupiter before arriving at Saturn in November 2004 to begin a 
4-year orbital tour of the ringed planet and its 18 moons.  
The Huygens probe will descend to the surface of one of the 
moons, Titan, in June 2005.

     JPL manages the Cassini mission for NASA's Office of
Space Science and Applications, Washington, D.C.

Galileo on course for Jupiter

     NASA's Galileo spacecraft flew by the Earth Dec. 8 at 7:09
a.m. PST at an altitude of 304 kilometers (189 miles) above the
South Atlantic Ocean, completing a three-year gravity-assist
program and setting a course to reach Jupiter in December 1995.
     "How sweet it is," said Galileo Project Manager William
O'Neil. "We are on the way to Jupiter."
     This, the third gravity-assist for Galileo, added about 3.7
kilometers per second (8,300 mph) to the spacecraft's speed in
its solar orbit and changed its direction slightly, so that its
elliptical orbit now will reach to the orbit of Jupiter, about
780 million kilometers (480 million miles) from the sun.
     Traveling at over 48,000 kilometers per hour (30,000 mph) on
its way to the Earth encounter, the spacecraft flew 110,000
kilometers (about 68,000 miles) north of the moon at 7:58 p.m.
PST Dec. 7. Departing from the Earth in a slightly southerly
direction, it crossed the moon's orbit at about 6:15 p.m. PST on
Dec. 8.
     JPL's Galileo flight team programmed the spacecraft to
measure the near-Earth environment and observe Earth and moon
during this flyby. Scientists will obtain a great many images and
spectral scans of the northern regions of the moon and of various
areas on Earth over a period lasting several days. This provides
scientific data from new perspectives in some cases, and helps
the scientists calibrate their instruments for the Jupiter
orbital mission planned for 1995-97.
     O'Neil said the project is very much looking forward to
"unprecedented" views of the Earth and moon, and that color
images, shot about every 15 minutes during a 14-hour period, will
be compiled into a video that is expected to be released Dec. 22.
"For 14 hours, we'll be able to construct effectively a movie of
the moon traversing the foreground of the Earth," he said.
     On the way to Jupiter, Galileo will fly within 960
kilometers (600 miles) of the asteroid Ida on Aug. 28, 1993.
     The Galileo orbiter will fly 10 different elliptical orbits
of Jupiter, with close passes by each of the major satellites and
extended observations of the planet and its magnetosphere.
Galileo's atmospheric probe, which will descend into Jupiter's
atmosphere on Dec. 7, 1995 to observe that environment for the
first time, is being checked out during the near-Earth flight.

The spacecraft was successfully commanded back to Array Normal Spin (ANS)
state at 6:08 A.M. this morning.  After ANS and star identification were
verified, the command was sent at 6:58 to enable Momentum Unloading
flight software.  After a short warmup period, a small momentum
unloading occurred.

Engineers have reported that the spacecraft is stable and nominally
processing stars for inertial reference.  Attitude, Articulation, and Control
subsystem engineers understand the events leading to yesterday's loss of
inertial reference problem and are implementing plans to avoid
reoccurrence.

Activities are underway to upload the C5 sequence on Friday, December
18th for execution beginning on the 19th.  C5 is the stored sequence that
performs tasks to prepare the spacecraft for transition to the Outer
Cruise phase of the mission.

The Mars Observer Ground Data System Encounter/Mapping Critical Design
Review is taking place today at JPL.

                  MARS OBSERVER MISSION STATUS
                        December 11, 1992

     All spacecraft subsystems are performing well.

     The radio science flight sequence is winding down and
scheduled for completion on Dec. 14, 1992.  The next flight
sequence will prepare the spacecraft for its transition to the
outer cruise flight mode in which the high-gain antenna rather
than the low-gain antenna will be used.  The outer cruise
attitude transition begins on Dec. 15, 1992.  The Mars Observer
camera "bakeout" to prepare the instrument for operation will
continue in this next sequence through Dec. 28, 1992.  

     A science experiment to observe Earth's geotail at a greater
distance than has been performed by other spacecraft started on
Dec. 9, 1992.  The geotail is the region of space in which the
solar wind is disturbed as Earth moves in its orbit around the
sun.  The experiment will use Mars Observer's magnetometer and
electron reflectometer to gather data on solar and magnetic
particle disruption in this region. 

     Star-ephemiris tables, uploaded about once a week, continue
to adjust the spacecraft's solar panels so that they are
beginning to point more directly at the sun and the high-gain
antenna is pointing more directly at Earth.  These adjustments
are planned to continue through Jan. 2, 1993, when the high-gain
antenna is pointing directly at Earth.

     Today the spacecraft is about 25 million kilometers (16
million miles) from Earth, traveling at a speed of about 23,500
kilometers per hour (15,000 miles per hour) relative to Earth. 
The spacecraft is traveling at a heliocentric velocity of about
105,000 kilometers per hour (66,000 miles per hour).

                        MARS OBSERVER STATUS REPORT
                            December 16, 1992
                              4:00 PM PST
                            Launch +82 Days

The Spacecraft Team reported that a loss of inertial reference caused the
spacecraft to enter Sun Comm Power at about 10:45 A.M. PDT this morning.
On-board systems initiated automatic transition to this state when the
Celestial Sensor Assembly's misidentified star threshold was exceeded.
This occurred on the second spacecraft revolution after a "Use" command
was sent to utilize the "Insertion+82 Star Catalog/Ephemeris" uploaded
this morning.

Engineers have verified that the spacecraft is safe and stable after
performing properly in making the change from Array Normal Spin.
Attitude, Articulation, and Control subsystem staff believe they
understand the problem and plan to command the spacecraft at 6:00 P.M.
PST this evening and again tomorrow morning (12/17) at 6:00 A.M. PST to
return to Array Normal Spin.

This evening's command will place the spacecraft in Sun Star Init state to
affect the desired return to inertial reference.  The spacecraft will remain
in this state until the desired return to inertial reference can be verified
and AACS engineering data can be closely studied.

The spacecraft will be commanded back to Array Normal Spin at 6:00 A.M.
Thursday.  After ANS is verified and star identification has been
reestablished, the command will be sent to enable nominal momentum
unloading.  At this point the spacecraft will have been returned to the
nominal configuration for completion of the mission inner cruise phase.
