Rerources FROM THE MOON
As well as metals – such as titanium, iron and magnesium - the Moon contains a rare gas called helium-3 that may, one day, solve. Earth's energy shortage. This false-colour image, taken from the Galileo spacecraft, shows the titanium-rich soils of the Sea of Tranquillity in blue. Most of the lunar highlands appear orange/red, indicating a low titanium and iron content.
