Now you can moonwalk in your very own NASA Saturn V Rocket Socks. The Saturn V rocket is best known today as the rocket that took Americans to the Moon, but when it was developed, it was intended to be much more. With the ability to put 118,000 pounds of cargo in low earth orbit, the Saturn V rocket had the largest payload of any American launch system, dwarfing even the later Space Shuttle with its 24,400-pound payload.
