I apologize for the long hiatus in this White Rock series, but I hope this entry will be worth the wait.

I thought it would be fun to start the week by taking stock of what's going on with all the active planetary missions out there.

When we last visited White Rock on Mars, both Mars Global Surveyor and 2001 Mars Odyssey were mapping the planet.

The HiRISE instrument on Mars Reconnaissance Orbiter really is a spy camera in space. Check out this sequence of nine images from the HiRISE archives, which Doug Ellison pulled together into an animation covering more than a year of Spirit's mission.

Exploring another planet is an expensive business. We all know this, but sometimes it hits home harder than others. Today was one of those times.

I spent a large portion of the day at the Lunar and Planetary Institute's library and presented my own poster during the poster sessions, so my coverage of Thursday's sessions is limited.

Last week Mars Climate Sounder collected its 20 millionth sounding at Mars. Mars Climate Sounder is scanning without problems, collecting science observations of the atmosphere of Mars. Mars Climate Sounder has now been observing Mars for over 17 months (three quarters of a Mars year and also approximately three quarters of the Mars Reconnaissance Orbiter primary science mission).

In the fourth installment in my look at one spot on Mars as seen through the eyes of different spacecraft, we finally get to a mission that is still operational: 2001 Mars Odyssey.

Last time, I gave some of the background information about my research. Now, armed with that knowledge, we can press forward and talk about what I do.

This is the second installment in my look at one enigmatic feature on Mars as seen by all its orbiters through the more than thirty years of spacecraft observations.

Opportunity is now following a rather leisurely autumn schedule, according to the latest update on the mission website. Some of the work Opportunity is doing involves staring skyward, looking for patterns in the clouds that pass overhead at this time of year. One of the guys at unmannedspaceflight.com has put together some nifty animations of the wispy cloud patterns.

While conversing with Ken Edgett about the smiley face on Mars he remarked to me how different Mars looks at different pixel scales, and in particular that there is a transition somewhere in the neighborhood of six to seven meters per pixel.

There have been so many missions to Mars, which have sent back so much data, that figuring out how to find images of places on Mars can be really overwhelming.

I thought this was a fun image to kick off the weekend. This isn't the first happy-looking crater to be photographed from Mars, but I really like this one; it's more goofy.

The story of a Sasquatch-shaped rock visible in a recent panorama from Spirit is getting a lot of play in the mainstream media, but fortunately, it's not being taken very seriously. (My favorite take on this picture is the lead from the Times Online story about it:

Dust from the sky has settled on both the rover deck and the surrounding landscape. The dust-covered solar cells will not be able to generate as much power as when they were clean. Unless a puff of wind dusts off the solar panels, Spirit may have difficulty surviving the approaching Martian winter.

It hasn't been that long since the Mars Science Laboratory landing site downselection meeting; it was quickly followed by a meeting in Europe on ExoMars, which is currently planned for a 2011 launch.
