PART 1: No update next week
NO UPDATE NEXT WEEK
The Thanksgiving holiday will be celebrated in the U.S. next week and due to the shortened work week updates-lfm will not be published.
NEW DATA ADDED TO WEATHER WORLDS SITE
If you haven't stopped by the site recently, or if you haven't yet signed up, be sure to go to the Weather Worlds activities page at: http://quest.arc.nasa.gov/mars/events/wwindex.html In addition to the new easy-to-read index, you will find a description of Pathfinder as a Martian weather station and real Pathfinder atmospheric data submitted by meteorologist Jim Murphy. Students from around the country have been collecting real-time data in their own backyards, which will also be posted online early next week.
SUBMIT YOUR KIDS' PICTURES/INFO FOR SHARING ONLINE
By now you must have a nice collection of images of your students at work, their writing and artwork. How about submitting them for posting in the LFM Kids' Corner? Directions for submitting photos and text can be found at: http://quest.arc.nasa.gov/mars/events/posting.html If you have questions on how to submit send email to: email@example.com Be sure to include a text overview of the work you send.

MARS GLOBAL SURVEYOR FLIGHT STATUS REPORT
[Editor's note: Status report prepared by Office of the Flight Operations Manager, Mars Surveyor Operations Project, NASA Jet Propulsion Laboratory] Friday, November 14, 1997 Operations on the Mars Global Surveyor mission continue to proceed smoothly one week after the resumption of aerobraking. This week, the flight team performed several small thruster firings to gradually drop the low point of the orbit back into the upper fringes of the Martian atmosphere. Currently, the low point of the orbit lies at an altitude of 77.3 miles (124.4 km). Friday night, at the high point of orbit #41, Surveyor will perform another thruster firing to slow down and lower the low point of the orbit by another four kilometers. The new low point altitude will cause the spacecraft to experience an air resistance force of 0.21 Newtons per square meter on every subsequent aerobraking pass. This amount of force is approximately one-third as strong as that proposed by the original plan, and is nearly equal to the average force as prescribed by the new mission plan. To put these force values in perspective, chief navigator Dr. Pat Esposito estimates that the orbit period will shrink at a rate of about 24 minutes per revolution as a result of flying through the atmosphere. After a mission-elapsed time of 372 days from launch, Surveyor is 183.58 million miles (295.44 million kilometers) from the Earth and in an orbit around Mars with a high point of 27,578 miles (44,383 km), a low point of 77.3 miles (124.4 km), and a period of 34.8 hours. The spacecraft is currently executing the P41 command sequence, and all systems continue to perform as expected. The next status report will be released on Wednesday, November 26.
