Moonwalk

Moonwalk

Fig. 5.20 . Charles Duke (1935- ) strolls across the lunar surface during the Apollo 16 mission in April 1972. Small impacting particles have sandblasted the lunar surface, producing smoothed, undulating layers of fine dust and rounding the surfaces of lunar rocks. Larger meteorites have pounded and churned the surface, producing a layer of ground-up rocky debris. (Courtesy of NASA.)
