The Jet Propulsion Laboratory has posted a short video showing some recent testing of an engineering model of the Mars Science Laboratory in their outdoor Mars Yard; they're testing the performance of the rover's driving capability over slopes of varying steepness and covered with bedrock, compacted sand, and very loose sand.

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.

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).

The Mars Exploration Rover (MER) mission emerged from its third solar conjunction this month and, as March roars in, is embarking on its 86th month on the Red Planet. While Opportunity roved away from a surface target it had been studying at Santa Maria Crater and on to an intriguing blue boulder, JPL engineers on Earth stepped up their efforts to recover Spirit, which has been silent, ostensibly in hibernation mode, since late March, nearly one year ago.

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.

It's always a relief when conjunction passes. Opportunity has gotten right back to work, sending down data acquired just before the moratorium, which spanned from January 27 to February 11.

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

Thanks to the work of several amateurs, Google Mars is a great tool for following the past and future peregrinations of the Mars Exploration Rover Opportunity.

Today Mars made its closest approach to the Sun -- as seen from Earth, that is. Why is this important?

Seven years ago this month, Spirit bounced down onto the surface of the Red Planet, rolled to a stop upright, and beeped home, ready to roll. Three weeks later, Opportunity not only bounced down safely and right into a small crater, but opened its

I've spent the day noodling around in the current issue of Icarus, following up some of the more interesting stories within its table of contents, and came across a picture of this very cool crater -- actually, set of craters -- on Mars.

Daniel Macháček has colorized some terrific images of Phobos and run them through some morphing software to make a seamless animation that appears to show Phobos rotating before you.

The Mars Express High-Resolution Stereo Camera (HRSC) team has just released several images from the most recent series of Phobos flybys to the Mars Express blog.

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.

Today the 365 Days of Astronomy podcast aired my contribution, Unmanned Space Exploration in 2011, about what to look forward to in solar system exploration this year.

In a lovely talk, in his uncommonly engaging way, Steve Squyres presents the portrait of him that now hangs in the Smithsonian's National Portrait Gallery.

These two movies were posted to the JPL website a couple of weeks ago, and they are just amazing.

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

While I was writing yesterday's blog entry on Mars Express' Phobos flybys I realized that I didn't understand Mars Express' orbit very well. So I sent an inquiry to the Mars Express blog, which they answered in a blog entry today.
