Eberswalde crater, formerly known as Holden NE crater, is a partially buried impact crater in Margaritifer Terra, Mars. The 65.3 km diameter crater, centered at 24°S, 33°W, is named after the German town of the same name, in accordance with the International Astronomical Union's rules for planetary nomenclature. It is a proposed landing site for the future Mars rover, Mars Science Laboratory. A delta located in the crater provides strong evidence of the prior existence of flowing water on Mars. It most likely was formed by flowing water. The delta was discovered by Michael Malin and Kenneth Edgett of Malin Space Science Systems through imagery taken by the Mars Global Surveyor in 2003. The delta likely formed some sedimentary rock. It suggests the climate on Mars during the Noachian epoch was made up of short, wet spells.
