Rosetta arrives at the comet at an altitude of 100 km in the first week of August, and will move progressively closer over the following two months, with the intention to orbit at an altitude of just 10 km, depending on the comet's activity. For Philae's deployment in November, Rosetta will come to within a few kilometres of the surface.

Work on Mars continues:


The sparks that appear on the baseball-sized rock (starting at :17) result from the laser of the ChemCam instrument on NASA's Curiosity Mars rover hitting the rock.

ChemCam's laser zapping of this particular rock was the first time the team used Curiosity's arm-mounted Mars Hand Lens Imager (MAHLI) camera to try and capture images of the spark generated by the laser hitting a rock on Mars. Their efforts were a success.

The video is compiled from single images from the MAHLI camera, taken during the 687th Martian day, or sol, of Curiosity's work on Mars (July 12, 2014).

Since Curiosity landed in Mars' Gale Crater in August 2012, researchers have used ChemCam's laser and spectrometers to examine more than 600 rock or soil targets. The laser itself has been fired more than 150,000 times. The process, called laser-induced breakdown spectroscopy, hits a target with pulses from the laser to generate sparks, whose spectra provide information about which chemical elements are in the target. Multiple laser shots are fired in sequence, each blasting away a thin layer of material so that the following shot examines a slightly deeper layer. In this case, "Nova" displayed an increasing concentration of aluminum as a series of laser shots from the rover penetrated through dust on the rock's surface.

Another successful soft sea landing for spaceX, yet again they couldn't recover it. It went kabbom, when it body slammed into the sea, possibly caused by it's own wave caused by it's engine.

Shame the camera iced up, but still, miles better than the last one.
