ESP_019570_2240-MF-LXTT-1.jpgPits and Fractures in Deuteronilus Mensae (EDM; credits for the additional process. and color.: Elisabetta Bonora - Lunexit Team) 115 visiteAcquisition Date: 29 September 2010
Mars Local Time (M.L.T.): 15:31 (middle afternoon)
Latitude (centered): 43,8° North
Longitude (East): 25,2°
Range to Target Site: 310 km (such as 193,7 miles)
Original image scale range: 31 cm/pixel (with 1 x 1 binning) so objects ~93 cm across are resolved
Map Projected Scale: 25 cm/pixel
Map projection: EQUIRECTANGULAR
Emission Angle: 14,4°
Phase Angle: 43,0°
Solar Incidence Angle (S.I.A.): 57°, with the Sun about 33° above the Local Horizon
Solar longitude: 156° (Northern Summer)MareKromiumDic 21, 2010

Santa_Maria_Crater-PIA13706-PCF-LXTT.jpgOrbital View of Santa Maria Crater (Absolute Natural Colors; credits for the additional process. and color.: Dr Paolo C. Fienga - Lunexit Team)115 visiteCaption NASA:"NASA's Mars Exploration Rover Opportunity approached Santa Maria Crater in December 2010. With a diameter of about 90 meters (295 feet), this Crater is slightly smaller than Endurance Crater, which Opportunity explored for about six months in 2004.
This image of Santa Maria Crater was taken by the High Resolution Imaging Science Experiment (HiRISE) camera on Mars Reconnaissance Orbiter".MareKromiumDic 20, 2010

PSP_005349_0930_RED_abrowse-0.jpgCircular Feature in the South Polar Residual Cap (Absolute Natural Colors; credits for the additional process. and color.: Dr Paolo C. Fienga - Lunexit Team)117 visiteThis 4 Km-diameter Circular Surface Feature near the Edge of the South Polar Residual Cap was recognized in Mariner 9 and Viking Orbiter images taken in the '70s, but its origin could not be inferred. It was therefore targeted for HiRISE stereo imaging.
The bright areas in this image are covered by CO2 frost, and the "Swiss Cheese" terrain typical of the South Polar Residual Cap covers much of the imaged area.
The Dark Walls of the Circular Depression do not have as much Frost on them, and are fractured in a polygonal pattern. Apparently the Surface of the Walls has been extensively modified by thermal expansion and contraction of water ice. It also appears that the "Swiss Cheese" Terrain of the Residual Cap has buried the Floor of the Circular Depression, as well as the Terrain surrounding the Feature, making it difficult to infer its origin.
Its circular symmetry is consistent with an impact origin, but there is no evidence of a Crater Rim or Ejecta Blanket (perhaps because they have been buried).
The Depression may also have formed by collapse, but there is little evidence of extensional fractures that would be expected around a Collapse Pit. Analysis of HiRISE stereo data may help the interpretation of this Feature.MareKromiumDic 19, 2010
