Jason Davis put together this neat summary of the checkered history of Mars exploration.

The Mars Climate Sounder team has recently confirmed a prediction of a weather phenomenon on Mars that we haven't been able to observe before.

The Mars Climate Sounder instrument provides routine nightside observations of atmospheric temperature and opacity that document the presence of rapidly evolving water ice cloud layers in the Martian tropics during the northern summer season.

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.

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

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.

I don't think there's any question what the big event of this month will be: MESSENGER is finally, finally entering orbit at Mercury on March 18 at 00:45 UTC (March 17 at 16:45 for me).

I dug around and found something unique: this cool heart-shaped feature on Mars -- my Valentine to you all!

In the past couple of months I've received several emails from scientists offering clarifications, corrections, or alternative points of view to previous posts, which is awesome and something that I enthusiastically encourage. Here's one of them.

Mars Reconnaissance Orbiter has just snapped another photo of Opportunity sitting on the ground on Mars. These pictures never get old.

Each day until the New Year, I'll be opening a door onto a different landscape from somewhere in the solar system. Where in the solar system are these squirrely spots?

Opportunity is on a kilometers-long eastward road trip across Meridiani Planum toward the rim of a large ancient crater named Endeavour; it'll be many months yet before she gets there.

Time to open the eleventh door in the advent calendar. Until the New Year, I'll be opening a door onto a different landscape from somewhere in the solar system. Where in the solar system are these sinuous ridges?

Time to open the fourth door in the advent calendar. Where in the solar system is this crater-specked mound?

Adrian Lark has posted several new flights over gorgeous Martian landscapes to his Youtube channel. My favorite of his recent ones is this dive into Zumba crater.

I left the first day of the Fourth Mars Science Laboratory Landing Site Community Workshop on Monday just as they were getting in to the site-specific presentations. I left with no concern that I'd miss anything, though, because I knew that once he got done presenting his own work on Gale Crater, Cornell grad student Ryan Anderson would be taking notes and blogging the presentations on the other three sites.

Two weeks ago Mars Reconnaissance Orbiter and Mars Climate Sounder (MCS) started a four-week campaign to support entry, descent, and landing phase for the next Mars rover, Mars Science Laboratory (or

I apologize in advance for the expanse of text, but I hope that some of you will find the details interesting.

Today, tomorrow, and Wednesday, about 200 scientists and engineers will sit in an over-air-conditioned room in Monrovia, California to participate in what is officially titled the
