MARS SURFACE FROM SPACE

FROM:  NASA 

This image of a circular depression on the surface of Mars was acquired on Jan. 5, 2015 by the High Resolution Imaging Science Experiment (HiRISE) camera on NASA's Mars Reconnaissance Orbiter (MRO). The spacecraft has been orbiting Mars since March 2006 and completed its 40,000th orbit around Mars on Feb. 7, 2015.  The target of this observation is a circular depression in a dark-toned unit associated with a field of cones to the northeast. At the scale of an image taken by MRO's Context Camera, which provides wide area views to provide context for high-resolution analysis, the depression appears to expose layers especially on the sides or walls, which are overlain by dark sands presumably associated with the dark-toned unit. The HiRISE camera's resolution, which is far higher than that of the Context Camera and its larger footprint, can help identify possible layers.  HiRISE is one of six instruments on the Mars Reconnaissance Orbiter. The University of Arizona, Tucson, operates HiRISE, which was built by Ball Aerospace & Technologies Corp., Boulder, Colo. NASA's Jet Propulsion Laboratory, a division of the California Institute of Technology in Pasadena, manages the Mars Reconnaissance Orbiter Project for NASA's Science Mission Directorate, Washington.  Image Credit-NASA-JPL-Caltech-University of Arizona.

SHOWING THE DUNES OF MARS WITH HiRISE

FROM:  NASA 

Nili Patera is one of the most active dune fields on Mars. As such, it is continuously monitored with the HiRISE (High Resolution Imaging Science Experiment) camera, a science instrument aboard NASA's Mars Reconnaissance Orbiter, with a new image acquired about every six weeks. By monitoring the sand dune changes, we can determine how winds vary seasonally and year-to-year. This observation is one of the more recent Nili images, acquired on March 1, 2014. Compared to an image acquired on Nov. 22, 2012, changes are obvious. The ripples on the dunes have moved, as well some of the dune boundaries, such as the one at upper left. New landslides on the central dune's lee face are apparent. Such changes, in just 16 months (and finer scale changes have been seen in just a couple of weeks), demonstrate the effectiveness of wind in modifying the Martian landscape. HiRISE is one of six instruments on NASA's Mars Reconnaissance Orbiter. The University of Arizona, Tucson, operates the orbiter's HiRISE camera, which was built by Ball Aerospace & Technologies Corp., Boulder, Colo.

OBSERVING THE ROVER FROM SPACE



FROM:  NASA 

NASA's Mars Science Laboratory rover Curiosity appears as a bluish dot near the lower right corner of this enhanced-color view from the High Resolution Imaging Science Experiment (HiRISE) camera on NASA's Mars Reconnaissance Orbiter.  The rover's tracks are visible extending from the landing site, "Bradbury Landing," in the left half of the scene. Two bright, relatively blue spots surrounded by darker patches are where the Mars Science Laboratory spacecraft's landing jets cleared away reddish surface dust at the landing site. North is toward the top.  For scale, the two parallel lines of the wheel tracks are about 10 feet (3 meters) apart. HiRISE shot this image on June 27, 2013, when Curiosity was at an outcrop called "Shaler" in the "Glenelg" area of Gale Crater.  Subsequently the rover drove away from Glenelg toward the southwest. When HiRISE captured this view, the Mars Reconnaissance Orbiter was rolled for an eastward-looking angle rather than straight downward. The afternoon sun illuminated the scene from the western sky, so the lighting was nearly behind the camera. Specifically, the angle from sun to orbiter to rover was just 5.47 degrees. This geometry hides shadows and reveals subtle color variations. The image is one product from HiRISE observation ESP_032436_1755.  Other image products from this observation are available at http://www.uahirise.org/ESP_032436_1755 .
