ESA celebrated the tenth anniversary of Mars Express' launch with a several-day science meeting during which they issued lots of press releases and numerous spectacular photos. My favorite of them all is this enormous image of Kasei Valles on Mars.
Mars gives up its secrets through the unseen colors of its rocks.
Виталий Егоров (Vitaliy Egorov) is a Russian space enthusiast who enlisted help of fellow enthusiasts to search for -- and maybe find -- the Russian Mars 3 hardware on the Martian surface. Here he explains how he did it.
Curiosity is inching her way through her first use of the drill on a Martian rock. She paused in the proceedings to capture a second Martian "selfie."
Mars Reconnaissance Orbiter captured a new view of Curiosity on Mars on January 2 (sol 145). Curiosity was in the same location as the one from which it shot the sol 137 panorama I posted earlier. You can see the rover's tracks leading all the way back to the landing site!
I asked Mars Reconnaissance Orbiter to take a photo, and it turned out better than I had imagined: an incredibly fresh, well-preserved, dramatically rayed oblique impact crater.
Welcome to my monthly survey of the activities of robots across the solar system! Tomorrow is the equinox at Mars; both Curiosity and Opportunity will be spending the month actively analyzing Martian rocks. It'll be a less active month for Cassini, as Saturn passes through solar conjunction late next month.
In 2008, Mars Reconnaissance Orbiter snapped an amazing photo of Phoenix descending to the surface of Mars under its parachute. Now it's repeated the feat, with Curiosity.
