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.

As Opportunity worked away on its winter science campaign, the Mars Exploration Rover mission quietly completed its eighth Earth year of exploring the surface of the Red Planet last week, and is now roving on into Year 9 of its 90-day mission.

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.

This week's lineup is a largely astronomical crowd so most of the conversation concerned dark matter and boiling exoplanets and imaging the black hole at the center of our galaxy.

Phobos-Grunt has returned to Earth, a lot sooner than it should have. Yesterday, at approximately 17:45 UT, the Russian spacecraft and its passengers, including a Chinese orbiter and the Planetary Society's LIFE experiment, descended into Earth's atmosphere.

We explore space for the noblest goals of science and exploration, and we often persevere in spite of challenges. But space exploration is fraught with bad things happening, or, to use the technical term, ouchies. The Planetary Society's Phobos LIFE biomodule will re-enter the Earth's atmosphere in the next few days with the rest of the Phobos-Grunt mission.

I'm not looking forward to spending the weekend sitting deathwatch on Phobos-Grunt. It's not science, and it's a sad event, so my instincts would lead me to other subjects. But it contains the Planetary Society's Phobos LIFE experiment.

It's the best of times for Mars exploration because we've got three orbiters and a rover studying the Red Planet. It's also the worst of times for my Russian, European, and Chinese colleagues who were part of the Phobos-Grunt mission.
