Hundreds of images from the Mars Reconnaissance Orbiter’s HiRISE camera are publicly available, if you know where to look.

There was good news and bad news in this morning's press briefing about Curiosity rover's upcoming landing on Mars, just eight weeks from now. First, the good news: the landing ellipse has shrunk. The bad news: there's a contamination problem with the drill, and the Odyssey orbiter is in safe mode.

Glen Nagle pointed me to two awesome papercraft models of the Curiosity rover that you can download and -- assuming you have a LOT of patience and a steady hand -- assemble.

Mars rover driver Scott Maxwell relates a story of how he handed Ray Bradbury an opportunity to drive on Mars.

Since you last visited, Opportunity has continued to drive downhill – well, what passes for ‘downhill’ on Cape York! – and is now not far at all from the northern edge of the Cape. From where she is now she sees the Meridiani desert stretching away to the north and west, the eastern hills on her right, and the Cape itself behind her. And around her? lots and lots of Homestake-like gypsum veins.

The Mars Exploration Rover Opportunity strolled out of her winter haven this May to continue the expedition around Endeavour Crater, roving into yet another Martian spring.

May 16, 2012 is the third martian anniversary of the start of Mars Climate Sounder (MCS) observations from Mars Reconnaissance Orbiter. MCS started measuring the atmosphere of Mars three Mars years ago, on September 24, 2006. We can now compare the weather and behavior of the atmosphere in three different years, and find the temperature differences to be surprisingly large.

After driving off Greeley Haven – where she stood patiently for 19 long weeks – Opportunity is now driving again. Not just turning, not just bumping, but driving.

As winter began to retreat in the southern hemisphere of the Red Planet, Opportunity was commanded to finish up her science assignments in April in preparation for leaving its refuge, and the Mars Exploration Rover mission rolled through its 100th month of exploration.

In a channel near a pedestal crater on the plains of Cerberus Palus, Mars, there are wacky swirl patterns.

A. J. S. Rayl has just posted her monthly update on the goings-on at Meridiani planum, noting that the update recaps the 99th month of the Mars Exploration Rover mission. There's a lot of detail on how the radio-tracking campaign is going. While she's not driving, Opportunity's acting like a lander, with radio antennas on Earth performing Doppler tracking to allow very fine measurement of Mars' orbital motion.

There's no hail or snow or sleet, though it is the depth of winter at Meridiani Planum and a cold unimaginable to us has gripped the landscape.

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

I'm not encouraging people to search individual images for the Mars Polar Lander anymore, for three reasons.

There's been a bit of buzz on the Web this week regarding an ESA press release titled

It appears that Phobos-Grunt was doomed before it launched on November 9, 2011. Cheap parts, design shortcomings, and lack of pre-flight testing ensured that the spacecraft would never fulfill its goals.

Roscosmos, the Russian Space Agency, has released its official report concerning the failure of the Phobos-Grunt spacecraft, which fell back to Earth from orbit on January 15 after failing to ignite the engines that were to take it to the largest Martian moon.
