Jezero (Mars crater)
The Jezero crater is located in the northern hemisphere of the planet Mars . It has a diameter of 49 km and was created at the time by a meteorite impact . This hurled sheet silicates or phyllosilicates onto the surface of the planet; they are still there today. Numerous clay minerals formed in the subsurface at 100–200 ° C , which is only possible in the presence of water. On November 19, 2018, NASA selected the crater as the landing site for the Mars 2020 rover mission .
The existence of the Jezero crater lake is assigned to around 4 billion years ago. Its catchment area covered around 15,000 km², and its tributaries brought it numerous suspended matter . The deposition of the material created wide plains that are interpreted as deltas . The crater lake covered around 500 km² and also contained a drain that left deposits of sediments . Open bodies of water probably still existed 3.8 billion years ago.
The crater was named in 2007 by the IAU after the place Jezero in Bosnia and Herzegovina , where "Jezero " means "lake" in Bosnian and other Slavic languages.
