Lunar Module Cockpit - Kennedy Space Centre
Interior view of a Lunar Module. Astronaut Neil Armstrong, the first man to walk on the moon, would have stood on the left, and Astronaut Edwin "Buzz" Aldrin stood on the right as they piloted the LEM to the surface of the Moon. This same small space served as the sleeping quarters as well, with Neil sleeping on the floor and Buzz sleeping in a hamock slung across the cabin.
The Main Hatch for egress, can be observed below the control panel. The handle is on the left allowing the door to open to the right. This design feature settled once and for all who would step out of the LEM first to walk on the Moon, that distinction going to Neil Armstrong not only because he was Commander, but because he occuppied the left hand space, making it impossible for Buzz Aldrin to step out first.
The longest duration stay on the Mooon was 3 days, set by Astronaut Gene Cernan and Geologist Astronaut Harrison Schmitt of Apollo 17 the final mission to the Moon.
