After cruising through winter solstice in late June, the Mars Exploration Rovers (MERs) roved into July taking every advantage of a winter that is by all appearances now proving to be rather mild for the Red Planet. At Gusev Crater, Spirit managed to maintain its power level and get back to doing a little bit of science, while on the other side of the planet, at Meridiani Planum, Opportunity finished photographing Cape Verde and began to chart its course back to Duck Bay where it will exit Victoria Crater.

I was delighted to receive an email from Morten Bo Madsen, who I knew from the Mars Exploration Rover mission as "that Danish magnet guy," the fellow responsible for the magnet experiments on nearly every American Mars mission. The magnets were originally designed to study the properties of airborne Martian dust, which would help determine its composition.

The Mars Exploration Rovers (MERs) celebrated a landmark milestone in June as they "trudged" through the very depths of their third Martian winter.

One of the ways that planetary scientists try to understand the origin and evolution of landforms on other planets is by studying similar kinds of landforms or "analogs" here on the Earth. For the past few days I've been working with a group of colleagues doing just that--specifically, studying dunes in the Great Sand Dunes National Park and Preserve in order to try to better understand the nature of sand dunes on Mars.

As Phoenix commanded the headlines with its flawless touchdown in the arctic region of the Red Planet this past month, the Mars Exploration Rovers (MERs) forged onward slowly, quietly and out of the spotlight, heading into the depths of their third Martian winter. Spirit persevered and held its own in terms of energy, while Opportunity, after six weeks of being stopped in its tracks with a shoulder joint injury, roved once more.

A majority of the people who work in planetary geology are usually associated with one or maybe two missions, doing all their research on the results from one instrument on one mission. But there are a few people whose expertise cuts across many space missions, and an even smaller number of people who seem to work on almost everything. Randy Kirk is one of those people.

It's time to check in on what's going on with our trusty robots around the solar system.

Here's what's happening on active planetary missions this week.

With winter settling in on the southern hemisphere of the Red Planet, the Mars Exploration Rovers (MERs) spent April working on their respective science campaigns and hunkering down in brutally chilly nights that are seeing temperatures drop to around -95 degree Celsius. As the month comes to an end at Gusev Crater and Meridiani Planum, there is good news and there is bad news.

I thought it would be fun to start the week by taking stock of what's going on with all the active planetary missions out there.

Brandishing the trademark resilience that has endeared them to millions of people around the world, the Mars Exploration Rovers kept their robotic noses to the grindstone through March, soldiering on into their third Martian winter with slightly more power than predictions anticipated and enough proven mettle to dodge a budgetary pothole on Earth that might have taken one of them out of action. Now, 50 months after Spirit defied the odds and bounced safely to an upright landing and Opportunity followed with the impossible scoring of a 300-million-mile hole-in-one, the twin robot field geologists are driving the MER mission into new territory once again.

I spent a large portion of the day at the Lunar and Planetary Institute's library and presented my own poster during the poster sessions, so my coverage of Thursday's sessions is limited.

The mantra of Mars exploration is "follow the water," and my research is no exception. Lately, I have been looking closely at the the Meridiani region, searching for evidence of water-formed minerals near some of the potential landing sites for the upcoming Mars Science Laboratory (MSL) mission.

Opportunity is now following a rather leisurely autumn schedule, according to the latest update on the mission website. Some of the work Opportunity is doing involves staring skyward, looking for patterns in the clouds that pass overhead at this time of year. One of the guys at unmannedspaceflight.com has put together some nifty animations of the wispy cloud patterns.

The Mars Exploration Rovers celebrated their fourth birthdays and began their fifth year of exploring this month -- and for the first time since the big dust storm hit the headlines last summer, Spirit and Opportunity made the news. It wasn't for the notable exploration or engineering milestone they had just achieved or the discoveries they've helped scientists make about a once very different Mars. It was because of an alleged "Bigfoot" sighting.

The mission was only supposed to last three months, maybe six months if all went well, but the Mars Exploration Rovers surprised everyone. Demonstrating an uncanny kind of "robot right stuff," they roved far beyond what anyone dreamed and now, in a matter of days, Spirit and Opportunity will celebrate their 4th birthdays and rove into their fifth year of exploring the Red Planet.
