About the Cover
ABOUT THE COVER: This mosaic of THEMIS daytime infrared images shows the densely dissected region of Warrego Valles, Mars, located near 43° S, 266° E. The dissection was likely caused by some form of water erosion, possibly due to surface runoff during a period of warmer climate or to subsurface runoff associated with the melting of a layer of snow or ice. This image covers an area of ∼120 x 160 km at a resolution of 100 m per pixel. IMAGE CREDIT NASA/JPL/ARIZONA STATE UNIVERSITY
