ArcadiaPlanitia-PIA12215.jpgFresh Impact in Arcadia Planitia (Natural Colors; credits: Lunexit)61 visiteThe team operating the Context Camera (CTX) aboard NASA's Mars Reconnaissance Orbiter frequently discovers new dark spots on Mars that, upon closer examination, turn out to be brand new impact craters. Sometimes only a single crater is present, but often there is a cluster of several craters.
Depending on the patterns and size, Crater Clusters are interpreted as indicating that the incoming meteorite broke apart before it hit the Surface.
In some cases, clusters could be formed by ejecta from other, larger impact craters.
Shown above are subframes of two Context Camera images of terrain in Western Arcadia Planitia (near 46,7° North Latitude and 183,2° West Longitude). Each covers an area about 6,5 Km (about 4 miles) across.MareKromium
