This Pluto mosaic was made from New Horizons LORRI images taken on July 14, 2015, from a distance of 49,700 miles (80,000 km). This view is projected from a point 1,118 miles (1,800 km) above Pluto’s equator, looking northeast over the dark, cratered Cthulhu Regio toward the bright, smooth expanse of icy plains called Sputnik Planum. Pluto’s North Pole is off the image to the left. This mosaic was produced with panchromatic images from the New Horizons LORRI camera, with color overlaid from the Ralph color mapper onboard New Horizons. Image credit: S.A. Stern et al.

This thrust fault is one of thousands discovered on the Moon by NASA’s Lunar Reconnaissance Orbiter. These faults resemble small stair-shaped cliffs, or scarps, when seen from the lunar surface. The scarps form when one section of the Moon’s crust (left-pointing arrows) is pushed up over an adjacent section (right-pointing arrows) as the Moon’s interior cools and shrinks.
