ESP_020922_1635_RED_abrowse.jpgProximities of Gratteri Crater (Absolute Natural Colors; credits: Dr Paolo C. Fienga - Lunexit Team)277 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".MareKromium

ESP_020929_1360_RED_abrowse.jpgUplifted Bedrock (Absolute Natural Colors; credits for the additional process. and color.: Dr Paolo C. Fienga - Lunexit Team)352 visiteCaption NASA:"Large Impact Craters expose deep Bedrock. After the transient cavity forms, the Crater Floor rebounds and creates a permanent structural Uplift, typically equivalent to about 10% of the Crater diameter.
A Crater approx. 70 Km (43,47 miles) wide like this one, can raise up and expose Bedrock that was approx. 7 Km (4,34 miles) lower in elevation prior to the Impact.
Deeper rocks are usually older, and on Mars the oldest rocks are interesting because they are more likely to have been altered by water and provide clues to ancient environments and processes. This image reveals good Bedrock exposures with diverse rock types (as indicated by colors and textures)".MareKromium
