Small steps, 41 years later

Still relatively pristine, the first tentative steps on another world are visible under a high sun in LROC Narrow Angle Camera observation M109080308RE, imaged last fall. Gardening by micrometeors, at the very least, may leave these first footfalls intact for the next 2 million years [NASA/GSFC/Arizona State University].
