Apollo 11 Lunar Module pilot Buzz Aldrin's bootprint. Aldrin photographed his bootprint about an hour into their lunar extra-vehicular activity on August 12, 1969 as part of investigations into the soil mechanics and regolith of the lunar surface. This photo also shows the undisturbed patch of ground before he placed his boot there.Photo credit: Buzz Aldrin
