Johann Heinrich Mädler produced the first reasonably good maps of Mars in the early 1830s. When doing so, they selected a particular feature for theprime meridian of their charts. Their choice was strengthened whenGiovanni Schiaparelli used the same location in 1877 for his more famous maps of Mars. The feature was later called "Sinus Meridiani" ("Middle Bay"), but following the landing of theNASA probe MER-B "Opportunity" in2004 is perhaps better known asMeridiani Planum .Beer crater lies in the southwest of
Meridiani Planum , about 8° from the prime meridian and about 10° west from Mädler crater. Schiaparelli crater is also in the region.External links
