Explanation: Frank Borman, James Lovell, and William Anders journeyed [6] from
Earth to the Moon and back again in December of 1968. From lunar orbit [7] ,
their view of craters in southwest Mare Fecunditatis is featured in this
stereo anaglyph, best experienced from armchairs on planet Earth with red/blue
glasses. Goclenius is the large impact crater [8] in the foreground. About 70
kilometers (45 miles) in diameter its lava-flooded floor is scarred by rilles
or grooves [9] , long, narrow depressions in the surface. Crossing the crater
walls and central peaks the rilles were likely formed after the crater itself.
In the background, the two large craters with smooth floors are Colombo A
(top) and Magelhaens. Magelhaens A, the background crater with the irregular
floor, is about 35 kilometers (20 miles) in diameter.
