Astro-Calendar: July / 50th Anniversary: Humans Land on Moon !

This is a photograph of the boot-print on the lunar surface of Apollo 11 Lunar Module Pilot Buzz Aldrin, the second man to walk on the Moon 50 years ago this month. This particular boot-print was part of an experiment to test the properties of the lunar regolith. This boot-print occurred about an hour after he and Apollo 11 Commander Neil Armstrong set-foot on the Moon on Sunday Evening, 1969 July 20. This photograph has become one of the iconic images of this historic space mission.
