In a now-routine act of obtaining detailed photographs of robots from Earth sitting on the surface of another planet, the HiRISE camera on Mars Reconnaissance Orbiter has captured a view of Opportunity sitting on the rim of Endeavour crater.

More than seven and a half years after landing, Opportunity arrived at its long-anticipated destination, the rim of Endeavour Crater, and in less than three weeks found something strange enough to launch a new Martian mystery.

The Mars Exploration Rover (MER) mission roves back into the exploration spotlight this month as Opportunity arrives at the rim of Endeavour Crater, a destination that wasn't even an impossible dream when the rover landed back in January 2004.

While doing my daily reading today I was struck by the awesomeness of two recent blog posts. Both were composed not by professional bloggers like me but by professional space explorers, one a scientist and the other an engineer.

Opportunity is at her goal. In this 3D anaglyph, taken on sol 2678 (yesterday, August 6, 2011), Opportunity's wheels are resting on strange lumpy bedrock.

Opportunity seemed to sail with the wind behind her back toward the western rim of Endeavour Crater this month as the Mars Exploration Rover team shifted gears in preparation for a whole new adventure, taking time out only to bid a final farewell both privately and publicly to Spirit.

For miles and miles of Martian terrain, Opportunity's view forward has contained a distinctive line of hills—the far rim of Endeavour crater.

Opportunity 'burned up' the Meridiani Plains in June as it raced toward its much-anticipated next destination and the Mars Exploration Rover (MER) mission cruised into the 90th month of what was originally to have been a 90-day tour.

The Mars Exploration mission suffered the loss of Spirit and shifted to one-rover operations in May, but Opportunity carried on, blasting across the plains of Meridiani to within 2 miles (3.5 kilometers) of its next major destination and discovery.

The intensified effort to recover Mars Exploration Rover (MER) Spirit came to an end early Wednesday morning Pacific time and NASA has now transitioned the mission to a single-rover operation focused on Spirit's still-active twin, Opportunity.

Yesterday, I remarked that despite the declaration of her death we'll be seeing Spirit frequently over the next few years, as long as Mars Reconnaissance Orbiter is still monitoring her landing site with its HiRISE camera. I said that Spirit is a lump that's relatively easy to spot because of her dark shadow. Well, Spirit's managed to make herself even easier to spot than that.

Alicia Chang reported today that, according to project manager John Callas, the last attempt to uplink a command to the Mars Exploration Rover Spirit will be made tomorrow. NASA will cease listening for signals from Spirit on Tuesday.

As Opportunity drove her little robot heart out, breaking the 28-kilometer mark on her odometer, and driving the longest backward drive ever, April proved to be another month of exhilarating highs for the Mars Exploration Rover mission and one extended low with only silence from Spirit, despite intensified efforts by her Earth crew to establish contact.

Regular readers of this blog will find the content of today's 365 Days of Astronomy Podcast familiar, because it's an update on what the solar system exploration spacecraft are up to, based on my monthly "what's up" updates.

April 2011 will see MESSENGER begin the science phase of its orbital mission at Mercury, and should, I think, also see the start of Dawn's approach observations of Vesta. At Mars, Opportunity is back on the road again, rolling inexorably toward Endeavour. At Saturn, Cassini will continue its focus on Saturn and Titan science.

The Mars Exploration Rover mission experienced a month of highs tempered by one haunting low as it neared completion of its 87th month of a three-month tour this month. While Opportunity wrapped up its work at the youngest, freshest crater the rovers have explored to date, Spirit remained silent as the point of maximum sunshine for the Martian year came and went, further dimming once high hopes that the rover would phone home and rove on as summer settled on the southern hemisphere of Mars.
