PART 1: Weather Worlds Web Form Available
WEATHER WORLDS WEB FORM AVAILABLE FRIDAY
By Friday morning, October 3, the Weather Worlds Web form that is now due October 10 (originally due Oct. 3), will be available at: http://quest.arc.nasa.gov/mars/events/weatherworlds.html Scroll down to the "Summary of Tasks" section where you will see a link to the newly created Web form under the second paragraph. Apologies for not giving you the URL directly to the form, but at press time (which is early this week due to having K-12 booth duty at the Children's Interactive Expo in San Francisco today), the form and link are still being created. However, both will be available by Friday. Be sure to fill them out and return them ASAP!
MARS PRESS BRIEFING SCHEDULED FOR OCTOBER 2
Scientists from the Mars Global Surveyor mission will discuss initial results from their investigations in a news briefing on Thursday, October 2 at 9 a.m., PST. Members of the Pathfinder science team will participate in a news briefing on Wednesday, October 8 at 10 a.m., PST. Pathfinder's lander and rover are currently active in the "extended mission" phase. If you miss the press briefings you'll still be able to catch them on the Internet by going to: http://quest.arc.nasa.gov/mars/video/news/ Here you will find an archive of past Mars Pathfinder press conferences.
NEXT WEBCHAT SCHEDULED FOR...
Mark your calendars for Thursday, October 9 at 9 a.m., PST when Dan Johnston will join us for another exciting WebChat! Dan is the trajectory and aerobraking design analyst on the Global Surveyor Operations Project, which is part of the Navigation Team. He will be able to fill us in on the aerobraking techniques and procedures and if they're working. Please have your kids prepare for the chat by reading Dan's bio BEFORE the chat: http://quest.arc.nasa.gov/mars/team/johnston.html By doing this, the kids will be less likely to ask questions that they can find answers to in Dan's bio. This will allow Dan to answer more questions, more thoroughly. To participate in the WebChat, RSVP at least 24 hours in advance to reserve a space for yourself. Send RSVP to: firstname.lastname@example.org You will receive confirmation of your registration and a password to enter the chat room. If the chat rooms are full by the time you register, you can still participate by watching the chat from the Observe Room at: http://quest.arc.nasa.gov/mars/events/interact.html
MARS PATHFINDER MISSION STATUS
[Editor's note: This status report was prepared by the Public Information Office, NASA Jet Propulsion Laboratory.] October 1, 1997 After experiencing difficulties in communicating with the Mars Pathfinder spacecraft for the past three days, the operations team was able to reestablish a brief two-way communications session Tuesday using the lander's auxiliary transmitter. Receipt of this beacon signal indicated that the spacecraft is still operational. The team began having communications problems with the spacecraft on Saturday, Sept. 27. These problems could be related to degradation of the spacecraft's battery. The last successful data transmission cycle from Pathfinder was completed at 3:23 a.m. Pacific Daylight Time on Sept. 27, which was Sol 83 of the mission. No signal was received from the spacecraft on the next Martian day, Sol 84, which began in the evening of Sept. 27. The team's transmission session began at 11:15 p.m. PDT. The lack of a signal, at that time, was thought to be caused by a possible computer reset incident, ground system problem or low condition. A reset or a low voltage condition, caused by the aging of the battery, would cause the spacecraft sequence to automatically stop and not execute its planned communication with Earth. The team attempted to communicate with the spacecraft again on Sept. 29 (Sol 85) and Sept. 30 (Sol 86) with no success. Tonight, on Sol 88 of the mission, the team will use the auxiliary transmitter again to attempt to acquire engineering data that will help them assess the cause of the communications problem. Meanwhile, the rover, which receives its instructions from Earth via the lander, is currently running a contingency program which has instructed it to stand still rather than begin its trek around the lander. The team will repeat these activities on subsequent days and attempt to receive telemetry that will give them more information about the health of the lander and rover. If Pathfinder operations do not return to normal tonight, a Mars Pathfinder team representative will provide an update on the situation at the beginning of the planned Mars Global Surveyor science news briefing at 9 a.m. PDT on Thursday, Oct. 2.
