Astronaut on Moon Fail

Astronaut Charles Duke hammers a core tube into the ground until it meets a rock and won't go any further. Then the hammer flies from his hand and he makes four attempts to pick it up by bending down and leaning to reach for it. He gives up and returns to the rover to get the tongs to pick up the hammer successfully.  During an Apollo 16 Lunar Surface EVA, April 1972.
