On February 21, 1972, Luna 20 soft landed in the rugged highlands between Mare Fecunditatis and Mare Crisium. The next day a sample return capsule blasted off carrying 55 grams of lunar soil. The Luna 20 descent stage still sits silently on the Moon, clearly visible in LROC NAC image M119482862RE [NASA/GSFC/Arizona State University].

Seeing small areas of the Moon at 50 cm per pixel often presents unexpected views, and sometimes it is hard to interpret the geology at first glance, much less what is up and what is down! What are the white streaks? How did they get there? Image is 600 meters wide, from NAC frame M109624226L [NASA/GSFC/Arizona State University].

Most mountains on the Earth are formed as plates collide and the crust buckles. Not so for the Moon, where mountains are formed as a result of impacts. Images taken looking across the landscape rather than straight down really bring out topography and help us visualize the lunar landscape. However such images can only be taken as the spacecraft rolls to the side, in this case about 70°, so the opportunities are limited. Foreground is about 15 km wide, view is northeast across the north rim of Cabeus crater [NASA/GSFC/Arizona State University].

As the Apollo 11 Lunar Module (LM) neared the surface, Neil Armstrong could see the landing area was right on the rough bouldery ejecta of West crater. He had to change the flight plan and fly the LM westward to find a safe landing spot. Image 742 meters wide, north is up [NASA/GSFC/Arizona State University].
