This seems completely idiotic to me, how could they not find a way to test the rover's multi-tasking abilities (and everything else they could think of) before they sent the thing to Mars? Too many chiefs? There is a growing feeling here that the robot may have been taxed too much. Perhaps too many "do this, do that" instructions were sent. That multi-tasking could have sparked the problem, according to sources here. Prior to its troubles on Mars, Spirit was being put through its paces -- doing things that were not tested with as much vigor here at JPL before being launched. Spirit does not have a huge track record of testing, a source said, for fear of damaging the robot and not meeting an unforgiving launch window. Following today’s JPL press briefing, Theisinger told SPACE.com that Spirit may have been overloaded with too many job tasks to handle at one time. "That’s possible…certainly that cannot be discounted," he said. http://www.space.com/missionlaunches/spirit_serious_040124.html
i don't if you meant there are no moons of mars, but there are 2, phobos and deimos. if you meant there just isn't much of them, then that would be true, b/c they're like 9 and 18 miles across.
Didn't the other one just land tonight? Glad to hear they got contact back...I am excited by what we have seen so far. DD
Second Mars Rover Sends Pictures to Earth NASA's Opportunity rover zipped its first pictures of Mars to Earth early Sunday, delighting and puzzling scientists just hours after the spacecraft bounced to a landing on the opposite side of the red planet from its twin rover, Spirit. The pictures showed a surface smooth and dark red in some places, and strewn with fragmented slabs of light bedrock in others. Bounce marks apparently left by the rover's air bags when it landed were clearly visible. "I am flabbergasted. I am astonished. I am blown away. Opportunity has touched down in an alien and bizarre landscape," Steven Squyres, the mission's main scientist, said early Sunday. "I still don't know what we're looking at." NASA began receiving the first of dozens of black-and-white and color images from Opportunity about four hours after its apparently flawless landing. Mars at the time was 124 million miles from Earth. Mission members hooted and hollered as the images splashed on a screen in mission control at NASA's Jet Propulsion Laboratory in Pasadena. Gov. Arnold Schwarzenegger was there with his wife, Maria Shriver, to watch the drama unfold, and walked through mission control shaking hands with the scientists. "The pictures just blow me away. We've certainly not been to this place before," deputy project manager Richard Cook said. Swaddled in protective air bags, Opportunity plunged into the martian atmosphere at more than 12,000 mph and bounced down on Mars at a force estimated to be just two to three times that of Earth's gravity. Engineers had designed it to withstand as much as 40 G's, said Chris Jones, director of flight projects at JPL. The six-wheeled rover landed at 12:05 a.m. EST in Meridiani Planum, believed to be the smoothest, flattest region on Mars. It lies 6,600 miles and halfway around the planet from where Opportunity's twin, Spirit, landed on Jan. 3. Initial analysis of the images suggested Opportunity landed in a shallow crater. Its low rim shouldn't block the rolling robot once it gets going, Squyres said. "It's smooth sailing to the horizon," he said. The rover's path off its lander also appeared unobstructed, unlike Spirit's landing, when a deflated air bags blocked its planned route to the martian surface, mission manager Matt Wallace said. Together, the twin 384-pound rovers make up a $820 million mission to seek out geologic evidence that Mars was a wetter world possibly capable of sustaining life. NASA launched Spirit on June 10 and Opportunity on July 7. Each carries nine cameras and six scientific instruments. On Wednesday, Spirit developed serious problems, cutting off what had been a steady flow of pictures and scientific data. Scientists rebooted the Scientists said Saturday they should be able to fix the problem in coming weeks. JPL director Charles Elachi said other NASA spacecraft, including Voyager, Magellan and Galileo, recovered from even graver problems. NASA administrator Sean O'Keefe broke open a bottle of champagne and toasted the mission. "As the old saying goes, it's far better to be lucky than good, but you know, the harder we work the luckier we seem to get," O'Keefe said, adding "no one dared hope" that both rover landings would be so successful. NASA sent Spirit to Gusev Crater, a broad depression believed to once have contained a lake. Opportunity was sent to Meridiani Planum, which scientists believe abounds in a mineral called gray hematite. The iron-rich mineral typically forms in marine or volcanic environments marked by hydrothermal activity. NASA launched two rovers to double its chances of successfully landing on Mars. As of early Sunday, there were a record five spacecraft operating on or around Mars, including two NASA satellites and one from the European Space Agency orbiting the planet.

Seriously tho', when something goes wrong how are they fixing the problems that these craft ultimately face.
