Milankovic Crater

Milankovič is a impact crater in the Diacria quadrangle. It has a diameter of 118.4 km and is located at 54.7° north latitude and 146.7° west longitude (213.3 E). The crater is easy to see on Mars photographs because it lies north of Olympus Mons and sits by itself in the flat plain in the North. It is named after Milutin Milanković (1879–1958), a Serbian geophysicist and astrophysicist.^[1] There is also an asteroid and a crater on the moon named after Milutin Milanković. Milanković Crater is the setting of the short story King of Mars, part of the Mars Mars 2194 by Canadian author Jack Stornoway.

Depressions in Milankovic Crater

The triangular depressions visible in Milankovic Crater contain water ice in the straight wall that faces the pole, according to a new study. This discovery was hailed as a big deal because it means pure water may be easily acquired for future cities on Mars.^[2] 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).^[3] ^[4] ^[5] ^[6] ^[7]
