One of the first things Neil Armstrong did after stepping onto the Moon was collect some soil.
Fifty years later, here it is at the Open University in Milton Keynes. In fact, the OU has been testing Apollo moon rock for decades. Incredible as it sounds, in their latest experiment, PhD student Hannah Sargeant is turning lunar dust into water.
Water is one of the most critical resources we need for space exploration. Not just for the life support needs of humans, but also to make rocket fuel, hydrogen and oxygen - it is propellant. So if we can produce that on the surface of the Moon, we can support long-term space exploration missions and produce the rocket propellant we need to perhaps use the Moon as a sort of pit stop for missions on the way to Mars.
