Astronauts definitely have the coolest job ever. Not only is it demanding and only plucks the best of the best,
they also get to experience phenomena that is literally impossible for other humans to experience.
While some of these phenomena are explained by science, other things are simply unexplainable.
Like this bizarre sound heard during an Apollo moon mission.
Freaky. Rockets? Gravity? Rocks on the moon? Something ELSE!?
