Left: Apollo 11 astronaut Edwin Aldrin photographed this footprint in the lunar soil as part of an experiment to study the nature of lunar dust and the effects of pressure on the surface. The dust was found to compact easily under the weight of the astronauts leaving a shallow but clear impression of the boots, characteristic of a very fine, dry material. The footprint image has also become one of the enduring symbols of the first visit to the Moon. (Apollo 11, AS11-40-5878). Right: Scientist-Astronaut Harrison H. Schmitt is photographed standing next to a huge, split boulder during the third Apollo 17 extravehicular activity (EVA-3) at the Taurus-Littrow landing site on the Moon. Schmitt is the Apollo 17 lunar module pilot. This picture was taken by Astronaut Eugene A. Cernan, commander. (Apollo 17, AS17-140-21496, 12 December 1972)
