The Mars Exploration Rovers are reaching new milestones and gaining newfound energy as winter slowly begins to pass on the Red Planet. Once again, Opportunity commanded the spotlight as it pulled up to the rim of the massive Victoria crater this week and began returning images that may redefine the word spellbinding. Twin sister, Spirit, meanwhile, is resigned to stay in its northward-tilted position for another month looking at the same scenery in order to collect the maximum energy supply for its solar panels.

The Mars Exploration Rovers, which bounced to landings in January 2004 with 90-day warranties, have survived their second winter solstice on the Red Planet and are still going strong more than two and a half years after landing.

The Mars Exploration Rovers (MER) are working right through the depths of the winter at their respective locations in Gusev Crater and Meridiani Planum. Although the twin robot field geologists are putting in short days and taking quality time to recharge, they still have team members marveling over their latest Martian finds.

The Mars Exploration Rovers (MER) are wheel deep in winter, and still faring well, working hard, and sending home interesting new finds despite the below freezing Martian temperatures. The next month or so will bring the season's coldest temperatures to the rover's present habitats, but so far, no one on the team is losing any sleep over whether or not they'll make it through, because these rovers just keep going and going . . .

The Mars Exploration Rovers are now well into their second Martian winter and, all things considered, both Spirit and Opportunity are faring pretty well for being, essentially, aging Baby Boomers on bitter cold, dusty alien planet some 50 million miles away from home.

Two years and 3 months after they bounced to landings at Gusev Crater and Meridiani Planum, the Mars Exploration Rovers are heading into their second, long cold Martian winter.

As autumn falls toward winter on the southern hemisphere of the Red Planet, the Mars Exploration Rovers are on the move again. Although the twin robot field geologists are roving as quickly as possible to their next major destinations, the pace is slowing down.

As early autumn descends on the southern hemisphere of the Red Planet, the Mars Exploration Rovers are on the move and picking up the pace as they rove toward their next major destinations.

As the Mars Exploration Rover mission presses onward into its third Earth year -- and second Mars year -- the twin robot field geologists are moving to new destinations.

The Mars Exploration Rovers have each completed their first Mars Year (687 Earth days) and are close to completing their second Earth year exploring their respective sites on the Red Planet. With both Spirit and Opportunity finding new variations of bedrock in the areas they are exploring, the mission is continuing to send the team holiday gifts in the form of intriguing discoveries.

There was a big news splash about two articles that appeared in Nature about Mars Exploration Rover Opportunity's landing site. The articles suggest two theories for the formation of the layered sulfur-rich deposits at Meridiani Planum that do not involve standing liquid water.

In its orbit around the Sun, the Red Planet has been returning to where it was when the Mars Exploration Rovers first landed back in January 2004, and, as the twin robot field geologists are marking the milestone of their first Martian year -- equivalent to almost two Earth years -- fireworks are flashing all around the planet. Although the cause of the fireworks is actually debris from Halley's comet, through which Mars is currently passing, the timing seems so metaphorically appropriate.

The Mars Exploration Rovers science team witnessed a bit of an expansion down here on Earth this month, while up on the Red Planet Spirit and Opportunity continued roving along. As Halloween nears, the twin robot geologists have put in another solid month's worth of work, overcoming every occasional "hiccup." At this point, as Mars' orbit brings it as close to Earth as it will get until the summer of 2018, both Spirit and Opportunity are moving into new territories at their respective inspection sites.

Despite a few unexpected bumps and curves in their explorations at Gusev Crater and Meridiani Planum, the Mars Exploration Rovers have been working away and both Spirit and Opportunity have put in a very productive month's worth of work on the Red Planet.

Spirit has returned enough pictures from the summit [summit #1] of Husband Hill for the Mars Exploration Team to have put together a 240-degree color panorama of her view, which they released at a news conference today, held at NASA headquarters in Washington D.C. In coming days, the rover will return the rest of the images to complete the full, 360-degree, color panorama.

The Mars Exploration Rovers are still going strong, and both robot field geologists will be working through the July 4th holiday.

Nearly a year and a half after landing on the Red Planet, the Mars Exploration Rovers are continuing to collect important science and impress the team with their resiliency.

The Mars Exploration Rovers have both encountered some truly challenging obstacles in recent days, but have also presented the team with some surprises, and continue to be in overall good health some 16 months after bouncing to a landing, and more than a year after completing their primary missions.

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.

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).
