PSP_002882_0940_RED_browse~0.jpgFresh Craters on the South Polar Layered Deposits (Natural Colors; credits: Lunar Explorer Italia)58 visiteThis image was taken in the Southern Spring, when the surface was completely covered by Carbon Dioxide frost. Therefore, most of the brightness variations in this scene are caused by topography.
The Polar Layered Deposits are broken into blocks by fractures in two directions. Neither set of fractures is parallel to the current scarp face, suggesting that they were not formed as the scarp was eroded, but instead are due to pre-existing weaknesses in the Polar Layered Deposits.
The (small?) craters that can be seen at about 23:00 - approx. in the central portion of the frame - appear to have formed at the same time by an impactor that broke up as it entered the Martian Atmosphere.
The presence of many craters such as these on the South Polar Layered Deposits indicates that they are not as young as the North Polar Layered Deposits, which have very few craters on them.MareKromiumApr 22, 2009
