PASADENA, Calif., Aug. 8, 2012 /PRNewswire-USNewswire/ -- Remarkable image sets from NASA's Curiosity rover and Mars Reconnaissance Orbiter (MRO) are continuing to develop the story of Curiosity's landing and first days on Mars. (Logo: http://photos.prnewswire.com/prnh/20081007/38461LOGO) The images from Curiosity's just-activated navigation cameras, or Navcams, include the rover's first self-portrait, looking down at its deck from above. Another Navcam image set, in lower-resolution...

Mars Reconnaissance Orbiter Catches Mars Sand Dunes In Motion

Images from NASA's Mars Reconnaissance Orbiter (MRO) show sand dunes and ripples moving across the surface of Mars at dozens of locations and shifting up to several yards. These observations reveal the planet's sandy surface is more dynamic than previously thought. "Mars either has more gusts of wind than we knew about before, or the winds are capable of transporting more sand," said Nathan Bridges, planetary scientist at the Johns Hopkins University's Applied Physics Laboratory in Laurel,...

NASA's Mars Exploration Rover Opportunity has nearly completed its three-month examination of a crater informally named "Santa Maria," but before the rover resumes its overland trek, an orbiting camera has provided a color image of Opportunity beside Santa Maria. The High Resolution Imaging Science Experiment (HiRISE) camera on NASA's Mars Reconnaissance Orbiter acquired the image on March 1, while Opportunity was extending its robotic arm to take close-up photos of a rock called "Ruiz...

About four billion years ago, there were lakes on Mars which may have been fed by short-lived rivers that were, in turn, fed by precipitation. These lakes filled craters that were formed by the impact of meteorites. Water accumulated in places where rivers broke through the crater rims. Deltas were formed at the mouths of the rivers, similar to how they are formed where rivers flow into lakes or seas on Earth. These are the findings of an international team of researchers led by Ernst Hauber...

Clay deposits found in one of the oldest riverbed-like channels on Mars shows some unusual signatures that may shed light on the history of water -- and possibly life -- on the red planet. Observations made by an instrument onboard NASA's Mars Reconnaissance Orbiter (MRO), currently circling the planet, already have shown substantial clay deposits that formed about 4 billion years ago in two regions of Mars, Mawrth Vallis and Nili Fossae, that indicate that water was more...
