It took Don Davis many hours of meticulous labor to assemble this beautiful postcard from Mars.

Today Opportunity sent back to Earth the last few frames of the "deck pan" self-portrait she took during the waning days of 2011. Her solar panels are very dusty, which isn't helpful. It's near winter solstice in her southern location on Mars, so the angled Sun is not providing as much power as it would in a different season.

As I was beginning my research for my two magazine articles on the Curiosity rover's upcoming mission to Mars, I needed to figure out for myself how exactly this gigantic, ungainly machine fit in to the context of past Martian missions.

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.

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.

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

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.

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.

Wednesday morning included some interesting conversations. Notably, I spoke with Pamela Gay, who is responsible for the MoonZoo citizen science program and who is presently working on developing a site through which the public will be able to help search for potential Kuiper belt objects for the New Horizons mission to encounter after the Pluto flyby.

Last week the Mars Exploration Rover team dumped another 90 sols' worth of data from Mars into NASA's Planetary Data System, the national repository for space mission data. As I did once before, I dove into this fresh pile of data to pull out Opportunity's color views of the distant rim of Endeavour crater.

There is a fascinating new page on the Mars Exploration Rover Pancam science team's website, full of color versions of Opportunity's microscopic images. The Microscopic Imager is one of the tools on the end of the robotic arm, and serves as a hand lens for the robot geologist to explore the rocks and sands of Mars in great detail.
