On February 24, 2007, the Rosetta spacecraft passed by Mars, the second of four planetary gravity-assist flybys on its long route to a 2014 rendezvous with comet Churyumov-Gerasimenko. At the time, they released two photos from the main science camera, OSIRIS.

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.

In celebration of the 40th anniversary of Mariner 9's November 13, 1971 arrival at Mars, Daniel Macháček has produced a morphed animation of the images that Mars' first orbiter took while approaching the planet.

With a new rover, Curiosity, on its way to Mars, Jason Davis takes a look at what we knew - or thought we knew - about the planet back in 1935.

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

November has already been a very good month for me in the print publication realm. I've had published not one, but two, feature articles on Curiosity, the Mars Science Laboratory rover.

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.

I'm preparing a talk for the Pacific Astronomy and Telescope Show here in Pasadena on Sunday afternoon at 1:45. I have spent the morning putting together a slide that I have long wanted to have for presentations.

There's one Mars landed mission for which there is a long 3D film, and that's Viking. Grab your 3D glasses, and be prepared to be transported to Mars.

Today and tomorrow I'm attending the New Horizons Workshop on Icy Surface Processes. The first day was all about the composition of the surface and atmosphere of Pluto, Charon, Triton, and other distant places.

Two weeks ago I posted an awesome video of Martian clouds in motion. Last week I explained how I accessed the Mars Express images that comprise the animation. Today I'm going to explain how I turned the five-frame animation of Mars Express images into a smooth movie.

Last Friday I posted an awesome video of Martian clouds in motion. This week I'll tell you how I made it. The how-to is split up into two parts. The first, today, is how to access Mars Express HRSC image data and process it into the individual animation frames, from which you can make an animated GIF.

Behold an amazing (if I do say so myself) video of Martian clouds in motion.

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's wheels are on a whole new different kind of rock: she has arrived at the rim of Endeavour crater, on Cape York.

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.
