00:01Is there water on the Moon?
00:04At first glance, the Moon looks a bit like a desert,
00:07and for a long time scientists were sure there was no water on it.
00:12Now though, we know that there is.
00:14But where is it? And could we use it?
00:19Most of the Moon's water is found at its south pole.
00:23Many craters there have no access to sunlight,
00:26and, says NASA, are some of the coldest parts of the entire solar system.
00:31The water here is permanent ice.
00:34Some has been frozen for 3.5 billion years.
00:37Temperatures are as low as minus 240 degrees Celsius.
00:41The LRO Lunar Orbiter revealed that there is ice lying just below the surface here,
00:47either as solid deposits or mixed with lunar dust.
00:50And there's a lot of it.
00:52Estimates suggest hundreds of millions of metric tons.
00:57There's also water in Moon dust, what's known as Lunar Regolith.
01:03NASA's LADEE mission showed that when rocks from space strike the Moon's surface,
01:09they kick up not only dust, but also traces of water,
01:13even in areas subject to sunlight.
01:16And they are traces.
01:17The Sahara Desert contains around 100 times more water than lunar dust.
01:26Can we access it?
01:28That's something for future lunar missions to find out.
01:32Either way, it won't be easy to extract.
01:35Temperatures are very low, the terrain is difficult, and it'll take a lot of tech.
01:42Water access will be crucial for future lunar missions.
01:46It could be treated and turned into drinking water.
01:50Or broken down into its components, hydrogen and oxygen, using electrolysis.
01:57These could be used for breathing or for rocket fuel.
02:02Until then, however, astronauts will still have to bring their water with them from Earth.
