English: Apollo 11 astronaut Edwin Aldrin photographed this footprint in the lunar soil with the 70mm lunar surface camera 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.
The image above was the third in a sequence showing the lunar soil before and after it was stepped on. The previous two images of this sequence (AS11-40-5876 & AS11-40-5877) have been used to make this motion gif: Apollo 11 Buzz Step.gif
