Kaiser (Martian crater)

Kaiser is a crater in the Noachis quadrangle of Mars, located at 46.6° S and 340.9° W. It was named in 1973 after Frederik Kaiser, a Dutch astronomer (1808–1872). Debris flows have been observed on some of the dunes in this crater. Some researchers believe that they may be caused by liquid water. Liquid water could be stable for short periods of time in the summer in the southern hemisphere of Mars. These gully-like debris flows may be denivation features caused by small amounts of ice melting. The dunes have been observed multiple times at high resolution by Mars Reconnaissance Orbiter and are actively eroding in the present day.

Within Kaiser is the small crater Moni.
