The Mars Exploration Rovers (MER) logged another major milestone in October as they completed a second Martian year of field geology and now may rove on through 2009.

It might not be the stuff of Broadway musicals, but the Sun and did "come out tomorrow" on Mars. Just eight weeks after dust from severe storms darkened the Martian skies and threatened their solar-powered lives, the Mars Exploration Rovers finished dusting off as much as possible and took off on their long-anticipated expeditions this month, with Spirit roving onto an old volcanic formation called Home Plate and Opportunity cruising into Victoria Crater.

I just received another batch of "tau" images from rover camera lead Jim Bell to add to my visualizations of the rovers' dark skies. These pictures provide a direct measurement of the opacity of the atmosphere between the rovers and the Sun.

With dust from the summer's storms floating down on and all around them, the Mars Exploration Rovers returned to their exploration agendas this month, picking up right where they left off in July when winds kicked the soils up into the southern hemisphere and forced them to hunker down and conserve power.

I haven't written an update on the dust storm at Mars recently for two reasons. For one, the rovers are out of immediate danger, so it wasn't as urgent. The other reason is that Jim Bell wanted Cornell to issue a press release with updated versions of the images and animations I've been putting together from the rovers' "tau" images.

It was to be a Martian summer to remember. Just one month ago, the Mars Exploration Rovers were set to embark on long-awaited adventures. At Meridiani Planum, Opportunity was preparing for its grand entrance into the magnificent Victoria Crater and on the other side of the planet Spirit was finally going to explore the top of Home Plate, an old, intriguing volcanic formation in the Gusev Crater area. Then a series of dust storms hit suddenly, it was a Martian summer to remember alright, but for far different, windswept reasons.

Both Spirit and Opportunity are still suffering under incredibly dark skies, but, amazingly, they are both "power-positive," meaning that they are managing to produce enough power from the limited amount of sunlight to keep the batteries fully charged.

The Mars Exploration Rovers (MERs) spent the month of June finishing work and clearing their agendas at their respective locales at Gusev Crater and Meridiani Planum in preparation for highly anticipated new assignments in July.

The Mars Exploration Rovers sent home field reports this past month -- some 1,200 days into their missions -- that drew gasps of amazement from both the science and engineering teams.

The Mars Exploration Rovers (MERs) traveled to new targets and made discoveries ranging from the magnificent to the mundane in April, four fast weeks that essentially led both of the twin robot field geologists to the next phase of their explorations.

It's been business as usual on the Red Planet this month as the Mars Exploration Rovers investigated new areas on their ever-moving missions to explore Gusev Crater and Meridiani Planum. Both Spirit and Opportunity chalked up yet another productive month of field geology as they roved onward in their fourth year on location, checking out more of the local environs some 149,597,900 kilometers (93 million miles) away on Earthlings' favored other planet.

Dust storms are beginning to whirl around Mars as spring blooms in the southern hemisphere of the planet and along the equator where the Mars Exploration Rovers (MERs) are roving into their fourth year with a second banner month of exploration.

The Mars Exploration Rovers (MERs) celebrated their 3rd anniversary this month and are now roving into their fourth year of exploration on the Red Planet.

Defying all the odds, the Mars Exploration Rovers (MERs) are wrapping up 2006 in new locations and roving into their fourth Earth year of exploring the Red Planet. Spirit is slated to celebrate the milestone on January 3, 2007 Pacific Daylight Time (PDT), with Opportunity marking the milestone just 3 weeks later, on January 24, 2007.

With both a superior conjunction and a long, Martian winter behind them, the Mars Exploration Rovers picked up the pace in November and drove on to new locations and research.
