Coord. (centered): 20,1° North Lat. and 250,3° East Long.
Spacecraft altitude: 274,9 Km (such as about 171,8 miles)
Original image scale range: 55,0 cm/pixel (with 2 x 2 binning) so objects ~ 1 mt and 65 cm across are resolved
Map projected scale: 50 cm/pixel
Map projection: EQUIRECTANGULAR
Emission Angle: 0,6°
Sun-Mars-Spacecraft (or "Phase") Angle: 39,1°
Solar Incidence Angle: 40° (meaning that the Sun is about 50° above the Local Horizon)
Solar Longitude: 34,7° (Northern Spring)

Dunes-PIA14879-PCF-LXTT.jpgMoving Rippled Dune-Front in Hershel Crater (Enhanced Absolute Natural Colors; credits for the additional process. and color.: Dr Paolo C. Fienga - Lunexit Team)197 visiteA Rippled Dune-Front in Herschel Crater on Mars moved an average of about 1 meter (such as about o1 yard) between March 3rd, 2007 and December 1st, 2010. Herschel Crater is located just South of the Equator, in the Cratered Highlands.
This is one of several sites where the MRO has observed shifting Sand Dunes and Ripples. Previously, scientists thought sand on Mars was mostly immobile. It took the mission's High Resolution Imaging Science Experiment (HiRISE) to take sharp enough images to finally see the movement. While Dust is easily blown around the Red Planet, its thin Atmosphere means that strong Winds are required to move Grains of Sand.MareKromium

Claritas_Fossae-PIA14461-PCF-LXTT.jpgFeatures of Claritas Fossae (Absolute Natural Colors; credits for the additional process. and color: Dr Paolo C. Fienga - Lunexit Team)196 visiteThe Claritas Fossae Region is characterised by systems of "Graben" running mainly North-West to South-East. A Graben forms when a block of the Planet's Crust drops down between two Faults, due to extension, or pulling, of the Crust itself.

Fienga - Lunexit Team)189 visiteA Rippled Patch of Sand in Becquerel Crater on Mars moved about 2 meters (such as about 2 yards) between November 24th, 2006 and September 5th, 2010. Becquerel Crater is located just north of the equator in the Arabia Terra region.

They are a few hundred meters to kilometers in diameter, but their heights are still unknown.MareKromium
