Bernard is a large crater in the Memnonia quadrangle of Mars, located at 23.4° south latitude and 154.2° west longitude.

It is 128 km in diameter and was named after P. Bernard, a French atmospheric scientist.

As craters get larger (greater than 10 km in diameter) they usually have a central peak.

[3] If one measures the diameter of a crater, the original depth can be estimated with various ratios.

Because of this relationship, researchers have found that many Martian craters contain a great deal of material; much of it is believed to be ice deposited when the climate was different.
