I've had a fun morning of noodling around learning how to write KML files, and have produced one for Google Mars that shows you all of the Mars Orbiter Laser Altimeter tracks that cross the area Opportunity has driven through already, as well as the area of Endeavour crater.
OK, it's time to look silly in your red-blue glasses again! When Tanya Harrison sent me those awesome 3D views of Olympica Fossae from Mars Reconnaissance Orbiter's CTX camera, she sent me two other sets of 3D landscapes on Mars.
The latest HiRISE images of the Phoenix polar lander, taken near Mars' northern summer solstice, show why we haven't heard from the spacecraft since it fell silent on November 2, 2008: it appears the solar panels have collapsed.
A recent entry by Bethany Ehlmann from the blog of the Planetary Geomorphology Working Group of the International Association of Geomorphologists demonstrates how you can combine the power of different types of data to tease out a rich story of the past history of one spot on Mars.
Yesterday was the Mars Reconnaissance Orbiter HiRISE team's latest flood of archived images, 1,025 of them. I skipped forward to page 42 (what other number would I pick?) and started browsing from there.
I saw this image at the Lunar and Planetary Science Conference so am happy they released it: a view of Opportunity sitting on the north rim of the little, fresh Concepción crater, taken on sol 2153 (February 13, 2010).
