It is the first cave to be discovered on the Moon and could protect astronauts from radiation.

Scientists have for the first time discovered a cave on the Moon.

At least 100m deep, it could be an ideal place for humans to build a permanent base, they say.

It is just one in probably hundreds of caves hidden in an “underground, undiscovered world”, according to the researchers.

Countries are racing to establish a permanent human presence on the Moon, but they will need to protect astronauts from radiation, extreme temperatures, and space weather.

Helen Sharman, the first British astronaut to travel to space, told BBC News that the newly-discovered cave looked like a good place for a base, and suggested humans could potentially be living in lunar pits in 20-30 years.

    and domes are expensive and time consuming to build

    Also architecturally impossible, since there’s nothing to stop them from flying upwards. Pressure vessels work best when rounded on every side.

    Edit: Unless you count a half-buried sphere as a dome.

    A cave on the moon is a find. Given the potential for neocolonialism in the next decade or three, it’s a boon for whatever program discovers one.

    There’s more of these known BTW. The new thing is just proof that the hole continues underneath like expected.

    There’s nothing but regolith on the surface of the moon-- finely powdered rock of unknown (and likely poor) assay for vital ores and minerals useful to bootstrap a colony.

    That’s just not true, there’s exposed rocky outcrops as well.

    You can get a long way with just the rock-building elements of silicon, iron, aluminum and magnesium, metals-wise (and maybe calcium with no air to bother you). Volatiles are the real prize everyone is after.
