Surface impressions of Rosetta’s comet

Images of comet 67P/Churyumov-Gerasimenko taken on July 14, 2014, by the OSIRIS imaging system aboard the European Space Agency’s Rosetta spacecraft have allowed scientists to create this three-dimensional shape model of the nucleus. Image credit: ESA/Rosetta/MPS for OSIRIS Team/MPS/UPD/LAM/IAA/SSO/INTA/UPM/DASP/IDA Surface structures are becoming visible in new images of comet 67P/Churyumov-Gerasimenko taken by the scientific imaging system OSIRIS onboard the European Space Agency’s Rosetta spacecraft.

NASA Rover’s Images Show Laser Flash on Martian Rock

NASA’s Curiosity Mars rover used the Mars Hand Lens Imager (MAHLI) camera on its arm to catch the first images of sparks produced by the rover’s laser being shot at a rock on Mars. Credit: NASA/JPL-Caltech/MSSS Flashes appear on a baseball-size Martian rock in a series of images taken Saturday, July 12 by the Mars Hand Lens Imager (MAHLI) camera on the arm of NASA’s Curiosity Mars Rover. The flashes occurred while the rover’s Chemistry and Camera (ChemCam) instrument fired multiple laser shots to investigate the rock’s composition. The images, strung together as a video, are available online at: http://www.jpl.nasa.gov/video/?id=1317…
