Abstract

We have the nineteenth century astronomers Wilhelm Beer and Johann Mädler to thank for establishing the prime meridian of Mars. They defined a permanent reference point on the planet’s surface which was used for determining an accurate value for the planet’s rotation and to construct accurate maps of Mars. This reference point, centered on a small feature we now know as Sinus Meridiani (Meridiani Planum), is still used today as zero longitude.
