About The Cover

Mosaic of three image sets from the Clementine spacecraft ultraviolet-visible camera of the lunar impact crater Tycho (85-kilometer diameter). A color composite is shown in mirror format on the left. The colors emphasize variations in surface units, where blues and greens indicate relatively recently exposed material, and green indicates a higher abundance of iron-bearing minerals. The red area surrounding Tycho is a ring of lower albedo impact melt. See page 1844 and related Reports on Clementine data beginning on page 1835. [Color composite image: produced at Brown University]
