Shadows cast from Victoria's capes and bays
This is from the "just plain cool" department. Among the many tasks assigned to the Mars Reconnaissance Orbiter imaging team is to create "digital elevation models," otherwise known as DEMs, for current and future landing sites on Mars. DEMs are,... More»

It's so crazy it just might work: Send Cassini between the rings and the planet

Beautiful Phobos photos
Today I got sidetracked from other projects by some amazing photos of Phobos released by the Mars Reconnaissance Orbiter HiRISE team. The images were captured in three filters, so they produced beautifully colored views of this moon. For reasons I... More»

Opportunity update: Approaching Cape Verde
As A. J. S. Rayl reported in her latest rover update, Opportunity is now driving toward Cape Verde, the steep cliff on Victoria crater's rim that borders the shallow ramp that the rover used to enter the crater. Cape Verde looks absolutely gorgeous... More»

Does Venus Express smell volcanoes?
One of the goals of ESA's Venus Express mission is to hunt down clues to the question of whether Venus is currently volcanically active or not. Although it doesn't have a handy catchphrase, the question of the timing of Venus' volcanism is kind of... More»

Playing around with Cassini images of Janus
Today's release from the Cassini imaging team was this one of Janus, a still from the sequence that I animated back in February. Just to orient you, Janus is one of Saturn's smaller moons; it orbits just outside the most visible part of the ring... More»
