After more than a year of active-duty research, the Mars Exploration Rovers have caught 'second winds' -- in part because of their new, recently uploaded software and, in part -- however strange it may seem -- from the planet's notorious dust devils.

In the 48 hours since Huygens' data first began streaming back to Earth, a few processed images of the channeled landscape and bouldery landing site have been released to the public. Now, the Descent Imager Spectral Radiometer team at the University of Arizona has put all of Huygens' images online for the public to view.

After a mere twelve hours of work, all six of the science teams on Huygens were able to report results this morning. You could easily tell the difference between the administrators and the scientists on this morning's press panel: the administrators looked bright, fresh, and well-rested, while the scientists looked decidedly weary.

Anticipation here at the European Space Operations Centre (ESOC) is rising to a fever pitch. The full complement of more than a hundred scientists are here from all over Europe and the U.S.; they are running around, greeting each other, getting ready for the long-awaited data.

In two days, it'll all be over; for better or worse, Huygens will have hit the ground on Titan, and back on Earth we'll be waiting to see whether the data will be returned. Today, I arrived at ESA's European Space Operations Centre (ESOC) in Darmstadt, Germany.

As Spirit rang in her new year at Gusev Crater on Mars Monday, NASA officials and mission team members celebrated the Mars Exploration Rovers first anniversary at an event that featured a press conference, storytelling session, and birthday party at the Jet Propulsion Laboratory (JPL).

The Mars Exploration Rovers are trudging ever onward through the dead of winter on the Red Planet dreaming, perhaps, if robots dream, of a white Christmas. But Spirit and Opportunity are robots after all and come this weekend

The Mars Exploration Rovers are roving ever on into new territories and deeper into the history books as they close in on the end of one full Earth year of active duty at their respective sites on Red Planet.

As winter gives way to spring on the Red Planet, the Mars Explorations Rovers are maintaining their 5-day a week work schedules and continuing to send surprises home to Earth. Despite a recurring 'ache' in one of her steering motors, Spirit is continuing her climb in the Columbia Hills toward a rock called Uchben, while her twin, Opportunity, is completing her work at Wopmay.

The Mars Exploration Rovers are returning more and more evidence that there was liquid water on Mars at some point in the distant past, team members reported at a telecom news briefing yesterday.

The worst of the Martian winter is over for the Mars Exploration Rovers, but the robots' own dark days appear to be looming as Spirit hits a 'bump' that's kept her at a standstill for a week now.

After nearly two weeks of sparse, infrequent communication, Spirit and Opportunity have survived winter solstice and resumed

During the last four weeks, the Mars Exploration Rovers have braved the Martian winter to continue their geologic field work, sending home more evidence of past liquid water on the Red Planet and images of bizarre geologic formations the likes of which no one has seen before.

As the Martian winter descends on Gusev Crater and Meridiani Planum, the Mars Exploration Rovers have hit the snowless slopes.

The twin rovers Spirit and Opportunity continue their trek across the varied surface of the Red Planet, climbing hills and descending into a crater. After a two-month journey of over 3 kilometers through rocky terrain, Spirit has now begun climbing the Columbia Hills, which were seen on the horizon in the early panoramas taken from the landing site. The rover is expected to spend much of its remaining life climbing the hills and analyzing their geological make-up. Meanwhile, on the other side of the planet, Opportunity is carefully descending into the stadium-sized depression dubbed

The Mars Exploration Rovers are each entering new chapters in their extended missions that are already returning more intriguing discoveries, but they are both beginning to slow down now as the Martian winter closes in on them.

During the last three weeks, the Mars Exploration Rovers have been continuing to rove and explore their respective regions of Mars. Spirit has continued her trek to the Columbia Hills in the Gusev Crater area of Mars, while on the other side of the planet, at Meridiani Planum; Opportunity has been investigating Endurance Crater.
