Laser "Footprints" on Mars

On the Cover: This image, produced from Mars Orbiter Laser Altimeter (MOLA) data, reveals abundant evidence for the past flow of liquid water on Mars. Shown here is the Chryse outflow region, located 315 to 330 degrees east and 0 to 20 degrees north. Thanks to MOLA, scientists now know the topography of Mars better than they do the topography of many regions on Earth.
