About the Cover

COVER Rendering from the Gravity Recovery and Interior Laboratory (GRAIL) mission showing free-air gravity anomalies of the Moon's farside. Here, red corresponds to mass excesses and blue to mass deficits. This map resolves spatial scales as fine as 13 kilometers and reveals impact basins, complex craters, and simple craters. For more results from the GRAIL mission, see the Reports on pages 668, 671, and 675.
