I wish this was breaking news but sadly it is not. This video making the rounds on the internet shows an Astronaut (Charles Duke of Apollo 16 to be precise) hammering a tube into the ground when he drops the hammer. Due to the limitations of the space suit, and of the moons gravity maybe, he has to go through some crazy space manuevers to pick it up. Some say the hammer is still there to this day... others say he eventually got the tongs and picked it up.
He drops the hammer at around 30 seconds, and his reaction shows Astronauts are just like us sometimes.
