But the weather was later discounted as the source, Initially, engineers believed bad weather on Earth - a thunderstorm near a Deep Space Network antenna in Australia - had caused the communications glitch. Spirit's internal clock also was running and had roused the rover several times on cue to communicate with NASA's Mars Global Surveyor and 2001 Mars Odyssey as they zipped overhead. Preliminary indications suggested the rover's radio was working, and it continued to generate power from the sun with its solar panels. NASA scheduled two other attempts Thursday night to communicate with Spirit. As of midday Thursday, it had sent no engineering or science data for more than 24 hours. The rover missed several scheduled opportunities to communicate, both directly with Earth and by way of two NASA satellites in orbit around Mars. 'It is precisely like trying to diagnose a patient with different symptoms that don't corroborate,' said Firouz Naderi, manager of JPL's Mars exploration program. Spirit acknowledged with a beep that it received the command, indicating an onboard problem.

Later, NASA send a command to Spirit as if it were in fault mode, anyway. NASA last heard from Spirit as it prepared to continue its work examining its first rock, just a few yards from where it landed.Д®arly Thursday, NASA initially heard nothing from Spirit that would indicate it was in 'fault mode,' a state that the rover enters by itself when it has experienced a problem. 'While it is cause for concern, it is not cause for alarm,' he said. Steven Squyres of Cornell University, the mission's main scientist, cautioned that communications problems are common on spacecraft. It also carried out preliminary work analyzing the minerals and elements that make up its surroundings. It has snapped thousands of pictures, including breathtaking panoramic views and microscopic images of the martian soil. 15, in another nail-biting moment for NASA, the rover safely rolled down a ramp onto Mars' ruddy soil without becoming snagged.

Until Wednesday, Spirit had functioned almost flawlessly and NASA scientists and engineers had been jubilant.Д¬ushioned by its air bags, the rover made a bull's-eye landing on Mars, surviving what was by far the most dangerous part of the mission - the descent through the atmosphere at 12,000 mph. The twin rovers are supposed to examine the Red Planet's dry rocks and soil for evidence that it was once wetter and more hospitable to life. Its twin, Opportunity, is expected to land on Mars late Saturday. Spirit is one-half of an $820 million mission. That's a concern we have - that's quite a serious event,' Theisinger said. 'Yes, something could break, something certainly could fail.

But if the problem lies with the rover's hardware, the situation would be far more grave - perhaps beyond repair.

If the software is awry, NASA can fix it from Earth by beaming patches across more than 100 million miles of space. Among the possible causes: A corruption of its software or computer memory. 'We now know we have had a very serious anomaly on the vehicle,' project manager Pete Theisinger said at NASA's Jet Propulsion Laboratory.Д®ngineers struggled to diagnose what was wrong with the rover. Since then, the six-wheeled vehicle has sent either random, meaningless radio noise or simple beeps acknowledging it has received commands from Earth. NASA received its last significant data from the unmanned Spirit early Wednesday, its 19th day on the surface of Mars. NASA's Spirit rover has stopped transmitting data from Mars in an ominous turn that baffled engineers and sent them scrambling desperately Thursday to figure out what brought the mission to a potentially calamitous halt. The novelty of our work includes the linking of multi-source, multimodal news content to extracted entities and topical structures for contextual understanding, and visualized in intuitive active and passive interfaces.PASADENA, Calif. These two interfaces trade-off between user-controlled and serendipitous exploration of news while retaining the story context. We present two intuitive interfaces for navigating content by topics and their related news events as well as serendipitously learning about a news topic. The system utilizes these many multimodal sources to link and organize content by topics, events, persons and time.

We introduce a novel architecture called News Rover for re-bundling broadcast video news, online articles, and Twitter content. Persons, places, times, and several surrounding topics can often succinctly represent a news event, but are only useful if they can be both identified and linked together. Every story is driven by key entities that give the story its context. News stories are rarely understood in isolation.
