The next time you’re walking on the Moon don’t be surprised if you come across a family photo, after a snap was revealed to have been left there by the youngest man ever to make the trip.
Apollo 16 pilot Charles Duke put the picture in a plastic folder and dropped it on the surface when he travelled there in 1972.
The photo, which features him, his wife Dottie and two sons, Charles and Tom, was apparently intended for intelligent life forms that would potentially come across it.
‘This is the family of Astronaut Duke from Planet Earth. Landed on the Moon, April 1972,’ the spaceman wrote on the back of the picture.
The snap was revealed when Mr Duke’s own photo of it was discovered at the Project Apollo Image Archive in America.
Robert Jacobs, Nasa’s deputy associate administrator for communications, said: ‘A lot of astronauts left some sort of personal memento.
Ok, so now we wait for the aliens to drop there own family photos, abi na!
