SubsurfaceIce-PIA12218.jpgSubsurface Ice (Natural Colors; credits: Lunexit)56 visiteThis 6-meter-wide (20-foot-wide) Impact Crater located in Mid-Latitude Northern Mars was created by an impact that occurred between Jan. 22, 2008, and Sept. 15, 2008, as bracketed by before-and-after images (not shown here).
The images shown here were taken by the High Resolution Imaging Science Experiment camera on NASA's Mars Reconnaissance Orbiter on Oct. 29, 2008, (left) and on Jan. 4, 2009. Each image is about 35 meters (115 feet) across.
The crater's depth is estimated to be 1,76 meters (5,8 feet).
The impact that dug the Crater excavated water ice from beneath the Surface. It is the bright material visible in this pair of images. A change in appearance from the earlier image to the later one resulted from some of the ice sublimating away during the Northern-Hemisphere Summer, leaving behind dust that had been intermixed with the ice. The thickening layer of dust on top obscured some of the remaining ice.
This crater is at 45,05° North Latitude and 164,71° East Longitude.MareKromium

Home_Plate-PIA12205.jpgSpirit at Home Plate59 visiteIn this view from orbit, the pale circular shape in the center is a low plateau called "Home Plate", about 80 meters (about 260 feet) across. The bright dot just to the left of Home Plate at the 9 o'clock position is NASA's MER Spirit. North is toward the top.
The view is a portion of an image taken on June 13, 2009, by the High Resolution Imaging Science Experiment (HiRISE) camera on NASA's Mars Reconnaissance Orbiter. At that date, Spirit had been embedded for more than a month in a patch of soft soil called "Troy".
During the subsequent 3 months, Spirit studied the unusually layered soil at the site while engineers used test rovers at NASA's Jet Propulsion Laboratory to assess possible maneuvers for getting Spirit away from Troy.
The site is at 14,6° South Latitude and 175,5° East Longitude. Home Plate is in the inner basin of the Columbia Hills range, inside Mars' Gusev Crater. Spirit has been exploring the Columbia Hills and nearby features since January 2004.MareKromium
