The Lunae Palus quadrangle is one of a series of 30 quadrangle maps of Mars used by the United States Geological Survey Astrogeology Research Program. The quadrangle is also referred to as MC-10. Lunae Planum and parts of Xanthe Terra and Chryse Planitia are found in the Lunae Palus quadrangle. The Lunae Palus quadrangle contains many ancient river valleys. The quadrangle covers the area from 45° to 90° west longitude and 0° to 30° north latitude on Mars. The Viking I Lander landed in the quadrangle on July 20, 1976, at 22.4°N 47.5°W / 22.4; -47.5. It was the first robot spacecraft to successfully land on the Red Planet.
