In space, no one can hear you scream "Rats!" – unless the video cameras are rolling, of course.
When Apollo 16 landed on the moon back in 1972, astronaut Charlie Duke had one job: Hammer a core tube into the lunar surface.
What should have been an easy job turned into a nightmare of logistics reminiscent of Gravity, minus the whole life-threatening part.
First, the tube hit a rock and wouldn't budge. Then Duke dropped his hammer, and due to the bulkiness of his space suit, he just couldn't pick it up no matter how hard he tried.
Eventually, Duke had no choice but to give up and return to the rover to get some tongs so he could pick up the hammer and start over.
So, is this where Alfonso Cuarón found inspiration for his Oscar-contender film? One can only speculate.
The video was originally posted in 2011, but recently gained attention on Reddit.
