Summary

[edit]
Description
Deutsch: Bei 30 Grad östlicher Länge und 25 Grad nördlicher Breite befindet sich in der Hochlandregion Arabia Terra der 415 Kilometer große Krater Cassini, benannt nach dem bedeutenden italienisch-französischen Astronomen Giovani Domenico (Jean Dominique) Cassini (1625-1712). Es handelt sich um einen sehr alten Krater, der bereits stark von der Erosion eingeebnet wurde. Aufgrund ihrer immensen Dimensionen bezeichnet man solch große Krater auch als Einschlagsbecken. Die schüsselförmige Vertiefung von Cassini ist von mehreren Kilometer mächtigen Lagen aus Sedimenten verfüllt, und der einst zwei bis drei Kilometer hohe Kraterrand ist bereits stark degradiert. Wissenschaftliche Untersuchungen deuten darauf hin, dass die einstmalige Vertiefung des Cassini-Beckens von einem stehenden Gewässer bedeckt war, wie dies auch bei einigen der Krater in der Umgebung angenommen wird. Die Menge des Wassers im Krater Cassini hätte etwa derjenigen des Baikalsees in Sibirien entsprochen, dem größten Süßwasserreservoir auf der Erde.

English: Located at longitude 30 degrees east and latitude 25 degrees north in the highland region of Arabia Terra is the 415 kilometer wide crater Cassini, named after the eminent Italian-French astronomer Giovani Domenico (Jean Dominique) Cassini (1625-1712). It is a very old crater that has already been severely leveled by erosion. Due to their immense dimensions, such large craters are also referred to as impact basins. Cassini's bowl-shaped depression is filled with layers of sediment several kilometers thick, and the rim of the crater, which was two to three kilometers high, is already severely degraded. Scientific research indicates that what was once the Cassini Basin depression was covered by standing water, as is believed to be the case with some of the craters in the area. The amount of water in the Cassini crater would have been about the same as that of Lake Baikal in Siberia, the largest freshwater reservoir on Earth.
