London, June 20 : Besides courage, determination and little bit of fear - American astronauts took soft porn pictures with them to the Moon!

Steamy pages from Playboy magazine were smuggled by pranksters at NASA into ring-bound checklists attached to the wrists of two spacemen on the Apollo 12 second manned landing in November 1969, reports The Sun.

But that was not all, shocked Pete Conrad and Al Bean found jokers had added captions to the naked girls, like: "Seen any interesting hills and valleys?"

Mission commander Conrad recalled: "I didn''t find them until we were on our first Moonwalk." (ANI)
