ESP_020922_1635_RED_abrowse.jpgProximities of Gratteri Crater (Absolute Natural Colors; credits: Dr Paolo C. Fienga - Lunexit Team)271 visiteCaption NASA:"Gratteri Crater, located about 150 Km to the South-East, ejected rocks that created millions of Secondary Craters over a Region at least 500 Km wide.
Many of these Secondary Craters are concentrated in "Rays", or lines extending radially from the Primary Impact Area (such as the "Gratteri Crater" Area).
Crater Rays on the Moon are typically bright at visible wavelengths, but on Mars they are often best seen in the Thermal InfraRed wavelengths, from temperature contrasts. This image confirms that this Ray contains many Secondary Craters (they are the small, sharp-rimmed Craters). Since millions of Secondary Craters form at once, they all have the same age and same degree of modification over time. Understanding the distribution of secondary craters provides information about impact processes, including escape of rocks that could become Martian meteorites on Earth".MareKromiumFeb 27, 2011

ESP_020793_1935_RED_abrowse-PCF-LXTT.jpgElliptical Impact Crater or Crater Chain? (Natural Colors; credits for the additional process. and color.: Dr Paolo C. Fienga - Lunexit Team)318 visiteCaption NASA:"This image shows what appears to be a highly Elliptical Crater, which would be unusual. Closer examination reveals that it is probably two overlapping Craters that formed concurrently, plus several smaller Craters aligned with the Long Axis of the elliptical depression.
This type of "Crater Chain" can form from a highly oblique impact, in which the Impactor (Bolide) trajectory is almost parallel to the Surface".MareKromiumFeb 27, 2011
