Enough people have asked me when we'll see Curiosity's first images from the surface of Mars that I sought out an answer. The short version: it depends.

Curiosity is equipped with seventeen cameras. One of them, the Mars Descent Imager (MARDI) will capture a movie as the rover descends to the surface.

Even robots deserve a break once in a while, and when the Mars Odyssey orbiter went into safe mode in June, Opportunity got the chance to hang out and leisurely take in her surroundings at the Red Planet, while the Mars Exploration Rover (MER) mission downshifted into lower gear.

Welcome to my monthly roundup of the activities of our intrepid robotic emissaries across the solar system! Curiosity is about to land; Opportunity has rolled through sol 3000; Odyssey is back online, having switched to a spare reaction wheel; Dawn is now in High-Altitude Mapping Orbit 2; and Cassini is taking advantage of its newly inclined orbit to get spectacular series of images of Saturn's rings.

Earlier today, unnoticed by the vast majority of the world, Opportunity reached and then silently passed a major milestone in her great adventure on Mars. At just before 3am, UK time, Opportunity began her 3000th sol, or martian day, on Mars.

A newly published paper shows trans-Neptunian object Salacia to be unexpectedly large; it's somewhere around the tenth largest known thing beyond Neptune. It has a companion one-third its size, making it appear similar to Orcus and Vanth.
