Data taken from Japan's Selene lunar orbiter has confirmed the existence of the 31 mile (50 km) long and 330 foot (100 metre) wide cavern Lava tubes can form in two ways.'Overcrusted' tubes form when thinner lava flows fairly close to the surface, developing a hard crust that thickens to create a roof above the moving lava stream.When the eruptions end, the channel created by the lava is drained leaving a tunnel a few metres beneath the surface.The moon also houses helium-3, a rare isotope on our planet, that could theoretically be used to generate cleaner, safer nuclear energy for Earth.One of the main targets for moon colonies is water, locked up in ice on the moon's poles.The Jaxa announcement comes after Japan in June revealed ambitious plans to put an astronaut on the Moon around 2030.That was the first time the agency had said it aimed to send an astronaut beyond the International Space Station.The idea is to first join a Nasa-led mission in 2025 to build a space station in the moon's orbit, as part of a longer-term effort by Nasa to reach Mars.

Professor Bernard Foing, ambassador of the European Space Agency-driven 'Moon Village' scheme, made the comments at a conference last week.

Potential moon resources include basalt, a volcanic rock that could be used as a raw material for 3D-printing satellites.

These could be deployed from the moon at a fraction of the cost of a launch from high-gravity Earth.

His Ph D thesis was on isotope ratios in meteorites, including surface exposure dating.

He was employed at Caltech's Division of Geological & Planetary Sciences at the time of writing the first edition.
