BACK BY POPULAR DEMAND!
Bridget Landry will join us once again in the Live From Mars chat room on Tuesday, August 26, from 8:30-9:30 a.m., Pacific Daylight Time. Most of you know Bridget as the deputy uplink systems engineer for Mars Pathfinder. But did you know that in her spare time she designs sci-fi costumes! To find out even more about Bridget and her interesting life, be sure to read her bio and journals at: http://quest.arc.nasa.gov/mars/team 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
STAY TUNED: NEW WEATHER ACTIVITY COMING YOUR WAY
A special, online Earth/Mars weather activity is in the works and will be available soon. If you were involved in the Planet Explorer Toolkit, or PET, think of this as "PET Lite"! It is an invitation to teachers and students to brainstorm weather observations, take data and see how their home sites and others across the US (and perhaps internationally) and Mars compare. More details will be made available to this mail list soon.
MARS GLOBAL SURVEYOR FLIGHT STATUS
[Editor's note: This status report was prepared by the Office of the Flight Operations Manager, Mars Surveyor Operations Project, NASA Jet Propulsion Laboratory.] August 15, 1997 As of today, Mars Global Surveyor is less than one month from an encounter with the red planet. Spacecraft performance continues to be flawless as Surveyor closes the 6.75 million kilometer distance to Mars at a rate of 242,500 kilometers per day. On Monday, the flight team transmitted commands to activate the Mars Orbiter Camera science instrument in preparation for two days of star imaging this week. Once per day on Wednesday and today, the spacecraft turned to point the camera at stars in the constellation Scorpius called Beta Scorpii, Omega-1 Scorpii, and Omega-2 Scorpii. Over the course of one hour on each imaging day, the camera observed stars within the target area. The camera team, led by Dr. Michael Malin, will use these star images to determine the best focus settings for a set of long-range Mars images that will be obtained during a three-day period beginning on Tuesday, August 19. In addition, the Thermal Emission Spectrometer science instrument will also observe Mars during this time period. After a mission elapsed time of 281 days from launch, Surveyor is 226.68 million kilometers from the Earth and is moving in an orbit around the Sun with a velocity of 21.80 kilometers per second. This orbit will intercept Mars 27 days from now, slightly after 6:00 p.m. PDT on September 11 (01:00 UTC, September 12). The spacecraft is currently executing the C10 command sequence, and all systems continue to be in excellent condition.
