About The Cover

Cover image expansion

COVER A view of the 930-kilometer Orientale impact basin on the Moon. A simulated digital terrain model is rendered 1 day after full moon. Overlain in color are gravitational anomalies measured by the Gravity Recovery and Interior Laboratory (GRAIL) spacecraft. Red indicates stronger-than-average gravity (blue, weaker), due to the topography and density of the underlying rocks. See pages 438 and 441.
