The Moon - Lunar Orbiter 5

Downslope boulder trail and boulder on the Moon

The Moon
Lunar Orbiter 5 image of a boulder (just right of center) which has rolled and slid down a slope and left a trail on the Moon's surface. This is within the crater Vitello, and demonstrates the small role that such processes, called gravity wasting, have on the lunar surface. The main source of surface modification on the Moon is meteorite and micrometeorite bombardment. North is up. (Lunar Orbiter 5, frame 168-H2)
