PASSPORT TO KNOWLEDGE - To MARS with MER
Spirit Continues to Send Back Amazing New Images From Mars
The Mars Exploration Rover team - both the scientists and the engineers - continue working at peak intensity, and round the clock, at NASA JPL. The mission team is carefully preparing Spirit to roll off the lander some time in the next week, most likely Wednesday or Thursday. (See JPL's recent press releases.) Other teams monitor Opportunity's trajectory for its January 24 landing, and begin to apply any changes in the Entry, Descent and Landing process, learning from what Spirit experienced on January 3. Meanwhile Steve Squyres' science team is analyzing every new image from the Pancam, and welcoming data from newly-activated instruments - like Mini-TES - as they come on line.
P2K is also busy: our live and interactive FIRST LOOK TV special debuts Saturday January 17, from 3-4 p.m. Eastern. Depending on mission requirements, viewers will see and hear Steve Squyres and others live from JPL, interacting with youngsters and families at a Mars Festival at the Houston Museum of Natural Science, commenting on the very latest images and information direct from Mars. (Click here for full details and satellite coordinates.)
This section of the site links you directly to the latest official information from NASA JPL, and to behind-the-scenes journals from several participants in the mission, hosted by Cornell University, The Planetary Society, and others.
The Mars Exploration Rover mission will be adding new pictures, data and stories each and every day: at times this and other websites may be a day or two behind breaking news, but the links to right and under should take you to the very latest information from NASA and its partners. Onwards and Upwards in the exploration of Mars!
Spirit's Surroundings Beckon in Color Panorama
January 12, 2004
The first 360-degree color view from NASA's Spirit Mars Exploration Rover presents a range of tempting targets from nearby rocks to hills on the horizon.
"The whole panorama is there before us," said rover science- team member Dr. Michael Malin of Malin Space Science Systems, San Diego. "It's a great opening to the next stage of our mission."
Spirit's flight team at NASA's Jet Propulsion Laboratory, Pasadena, Calif., continues making progress toward getting the rover off its lander platform, but expected no sooner than early Thursday morning. "We're about to kick the baby bird out of its nest," said JPL's Kevin Burke, lead mechanical engineer for the rover's egress off the lander.

The color panorama is a mosaic stitched from 225 frames taken by Spirit's panoramic camera. It spans 75 frames across, three frames tall, with color information from shots through three different filters. The images were calibrated at Cornell University, Ithaca, N.Y., home institution for Dr. Jim Bell, panoramic camera team leader.
Malin said, "Seeing the panorama totally assembled instead of in individual pieces gives a much greater appreciation for the position of things and helps in developing a sense of direction. I find it easier to visualize where I am on Mars when I can look at different directions in one view. For a field geologist, it's exactly the kind of thing you want to look at to understand where you are."
Another new image product from Spirit shows a patch of intriguing soil near the lander in greater detail than an earlier view of the same area. Scientists have dubbed the patch "Magic Carpet" for how some soil behaved when scraped by a retracting airbag.
"It has been detached and folded like a piece of carpet sliding across the floor," said science-team member Dr. John Grotzinger of Massachusetts Institute of Technology, Cambridge.
Spirit's next step in preparing to drive onto the surface of Mars is to sever its final connection with the lander platform by firing a cable cutter, which Burke described as "an explosive guillotine." The planned sequence after that is a turn in place of 115 degrees clockwise, completed in three steps over the next two days. If no obstacles are seen from images taken partway through that turn, drive-off is planned toward the northwestern compass point of 286 degrees.
Spirit landed on Mars Jan. 3 after a seven-month journey. Its task is to spend the next three months exploring rocks and soil for clues about whether the past environment in Gusev Crater was ever watery and suitable to sustain life. Spirit's twin Mars Exploration Rover, Opportunity, will reach Mars Jan. 24 PST (Jan. 25 Univeral Time and EST) to begin a similar examination of a site on a broad plain called Meridiani Planum, on the opposite side of the planet from Gusev Crater.
