"ONLINE FROM JUPITER"

U P D A T E # 3 1

PART 1: Moon mnemonic winners
PART 2: Evaluation gifts
PART 3: Status of the spacecraft


MOON MNEMONIC WINNERS
During the active portion of Online from Jupiter, we ran a contest
for students to create mnemonics based on the first letters of the
moons of Jupiter.  The entries below have been chosen as the winners.
If youare on the list, please send an Email note to marc@quest.arc.nasa.gov
with your snailmail address so we can forward your prizes.

Thanks so much to everybody that particpated.  There were many more
good entries that we weren't able to choose.

Jennifer Stapleton, Grade 6, Kerrisdale Elementry:
Mice Are Able To Intimidate Eager Greedy Cats

Teresa Morelli, Grade 6, Holy Family Middle School:
Many Animals Are Tempted Into Eating Grilled Chocolate Ladybug Hamburgers
Loaded Enormously Alongside Chopped Potato Sauce

Ryan Felton, Grade 3, Indian Creek Intermediate School, Trafalgar, IN:
My ape ate ten icky ewwie gooie corn-cobs.

Rebecca Pike, Grade 12, Palisade High School:
Martha Almost Always Tries Iodine Everytime Grandma Crashes

Christine Sulc, Grade 2, Island Park Elementary, Mercer Island, WA:
My Aunt Anna Talked In Excitement, "Gee, Cool."

Tia Corbett, South Brunswick Middle School, Southport, NC:
Moon, all around the imperious Earth, grant carefully little hopes, little
excitements, and carry people's sweethearts.

Jason Dooney, St. Catherine of Siena School, Horsham, PA:
My ant ate the incredible edible giant cow.

Markland Fridae, Grade 3, Waggoner Elementary School, Winters, CA:
Many Ants Are Tickling Irritatingly; Everyone's Going Crazy!
Look How Large Enemy Ants Carry Picnic Supplies!

Michael Hamar, Porterville Pioneer Middle School, Porterville, CA:
Meteors and asteroids travel in every galaxy continuously.

EVALUATION GIFTS
We promised to choose at random folks who helped us by filling
out an evaluation, with an emphasis on those who provided
constructive suggestions for how we can improve next time
around.  We were delighted to receive about 450 forms back.
Thank you so much for the outstanding response.  

We will be receiving some Galileo videotapes, posters and Jupiter
lithographs to distribute to the lucky winners shortly. About 25 
gift packs will be sent out during the third week of March.  
So if you haven't received something by the end of the month, 
you can stop crossing your fingers for luck.  But please know 
that your comments are proving very useful. 

GALILEO MISSION STATUS
March 1, 1996
Galileo is continuing to play back tape-recorded atmospheric 
science data received from the probe during its Dec. 7 descent 
into Jupiter's atmosphere. This week the flight team scheduled a 
pause in playback activities to test various strategies for 
operating  the tape recorder during the spacecraft's two-year 
orbital mission. Next week they will resume probe science 
playback, which is scheduled to conclude on April 15.

The tape-recorded information confirmed and extended the 
probe data already in hand and added engineering data to help the 
probe scientists analyze their data and understand the nature and 
activity of  Jupiter's upper atmosphere.  Meanwhile, scientists 
associated with some of the orbiter spacecraft instruments are 
studying data on the space environment sent to Earth in real time 
during the close approach to Jupiter.  

Galileo engineers are preparing for a major spacecraft 
maneuver on March 14.  This activity, called the "perijove raise 
maneuver," will almost double the spacecraft's orbital speed and 
reshape its orbit around Jupiter. The maneuver is designed to 
lift the closest point of the spacecraft's orbit from about 
185,000 kilometers (115,000 miles) away from Jupiter to a region 
that is beyond the orbit of Europa, about 670,000 kilometers 
(420,000 miles) out. This orbit will keep the spacecraft away 
"radiation" belts. 

The Galileo team is also busily finishing and testing the 
new computer software set that will operate the spacecraft 
through its orbital mission. Replacing the modified software 
installed in the spacecraft in January 1995, this set will 
include data compression and a wide range of telemetry speeds to 
allow a substantial increase in the amount of information the 
spacecraft can send to Earth.  Essential elements of the new 
programming have been running day and night in the Galileo 
spacecraft simulator at JPL. 

The spacecraft is operating normally, transmitting at 16 
bits per second.  It is currently 19 million kilometers (12 
million miles) from Jupiter, still receding in its long 
elliptical orbit, and 869 million kilometers (539 million miles) 
the Earth.
