The Mars Exploration Rovers have left wheel tracks all over their landing sites, but for some reason this pair of wheel tracks, left in the sand ripple on the rim of Victoria crater and now viewed from below, tickled my fancy. Thanks to James Canvin for the lovely panorama.

Mars Exploration Rover scientists, engineers and enthusiasts have been playing the waiting game for 10 weeks, watching the much-reported dust storm subside so that Opportunity could get back to doing what it does best - exploring craters.

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.

Although Mars' atmosphere continues to be rather dusty, the storm has abated enough that both Mars Exploration Rovers have resumed a relatively normal level of activity. For Opportunity, that means a drive to the very edge of Victoria crater.

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'

The skies aren't quite as dark as they have been, for both Spirit and Opportunity. In fact, Spirit has enough power now to be doing a little work with its robotic arm.

Yesterday evening the Mars Exploration Rover mission posted an update that states

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.

The dust storm continues at Mars, but both rovers continue to be power-positive.

Opportunity has ceased operations for a couple of days because the amount of sunlight available is low due to an unpredicted dust storm.

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.
