Milankovič (Martian crater)

Milankovič is a crater in the Diacria quadrangle of Mars, having a diameter of 118.4 km. It is located at 54.7° north latitude and 146.7° west longitude. The crater is easy to see on Mars photographs because it lies north of Olympus Mons and sits by itself in the flat plain of Vastitas Borealis.

Exposed ice sheetsEdit

Many triangular shaped depressions are visible in Milankovič Crater. According to a team of researchers, these depression display water ice in the straight wall that faces the pole. Eight sites were found with Milankovic Crater being the only one in the northern hemisphere. This discovery is important because the ice lies under only a meter or two of cover. Research was conducted with instruments on board the Mars Reconnaissance Orbiter (MRO).[2][3][4][5][6]

The following images are ones referred to in this study of subsurface ice sheets.[7]

In cultureEdit

Milanković Crater is the setting of the short story King of Mars, part of the Mars Mars 2194 by Canadian author Jack Stornoway.

Coloring of the base map indicates relative elevations, based on data from the Mars Orbiter Laser Altimeter on NASA's Mars Global Surveyor. Whites and browns indicate the highest elevations (+12 to +8 km); followed by pinks and reds (+8 to +3 km); yellow is 0 km; greens and blues are lower elevations (down to −8 km). Axes are latitude and longitude; Polar regions are noted.
