Our Moon holds this key to space travel

Apollo-era Moon rocks showed no evidence of water on the Moon, so scientists in the 1960s thought our satellite was dry.

But in the 1990s, the evidence of water started trickling in as lunar orbiters observed traces of hydrogen atoms, which could come from water molecules.

In 2009, NASA sent part of an Atlas V rocket to smash into the Moon and release a plume of dust for a second spacecraft, called LCROSS, to analyze.

LCROSS also found evidence for hydrogen molecules, lending more evidence to the presence of water.

Since then, with data from other missions like NASA’s Lunar Reconnaissance Orbiter and India’s Chandrayan-1 orbiter, scientists now understand where to find the Moon’s water.

On the Moon’s south pole, there are areas in craters that are permanently shadowed from the Sun’s oppressive heat and radiation.

This is where scientists think there could be stores of water ice.

The Moon’s water could provide not only something for astronauts to drink, but also the ingredients to create oxygen and even rocket fuel.

The first phase of Artemis, slated to launch sometime in 2021, will deliver several spacecraft to the Moon to determine how much water there is, and where it is.
