THEMIS: Jezero Crater delta landing site

Jezero Crater delta landing site (THEMIS_IOTD_20190812)THEMIS Image of the Day, August 12, 2019. At the top of today’s VIS image is a delta deposit that was created by the flow from the rim channel into the crater. Deltas form when sediments settle out due to a decrease in speed of a river system.

Deltas often form where large rivers flow into the ocean, like the Mississippi and Nile deltas. This can also occur where rivers flow into large lakes, such as the Great Salt Lake and Lake St. Clair river deltas. It is believed that the Jezero Crater delta formed this way.

The delta in Jezero Crater has been chosen as the landing site for the Mars 2020 rover mission.
