Mare Frigoris


Mare Frigoris is a lunar mare in the far north of the Moon. It is located in the outer rings of the Procellarum basin, just north of Mare Imbrium, and stretches east to north of Mare Serenitatis. It is just north of the dark crater Plato.

Geology

The basin material surrounding the mare is of the Lower Imbrian epoch, while the eastern mare material is of the Upper Imbrian epoch, and the western mare material is of the Eratosthenian epoch.

Names

Like most of the other maria on the Moon, Mare Frigoris was named by Giovanni Riccioli, whose 1651 nomenclature system has become standardized. Previously, William Gilbert had included it among the Insula Borealis in his map of c.1600, and Michael Van Langren had labelled it the Mare Astronomicum in his 1645 map. Pierre Gassendi called it the Boreum Mare.

Mare Frigoris is the dark band extending from upper left to lower right. Mare Imbrium and Sinus Iridum are in lower left. Prominent craters include Plato with dark flat floor in bottom center, Harpalus near left edge within the mare, Philolaus at top center, and Aristoteles in lower right within the mare.

In popular culture

This area of the Moon featured prominently in 'Behemoth', the second episode of the 1973 BBC science fiction mini-series Moonbase 3.
Mare Frigoris was intended to be the original landing site of the fictionalised version of Apollo 15 in the Apple TV+ series For All Mankind, although in the show the crew decided last minute to divert the landing to Shackleton crater in the Lunar south pole upon finding out there is a high concentration of water ice in the area.
