How China is sending man back to the Moon to mine safe nuclear power and become the world’s energy giant - Telegraph
A fully-loaded spaceship’s cargo base could power a quarter of the world for a year. This means that helium-3 has a potential economic value in the order of about £1 billion a ton, making it the Moon’s most valuable commodity except perhaps for astronomy and promoting tourism.
China’s lunar exploration programme is proceeding fast, strongly attracted by the prospect of helium-3 mining. In 2013 China managed to land a lunar robot lander. The final stage of their current programme intends sending a robotic craft to the Moon that will return lunar rocks to the Earth.
