Underground caves found on Mars:

Researchers from the US Geological Survey (USGS) have found underground caves on Mars.

Finding such caverns on Mars is important for researchers keen to find a place for humans to build a base on the planet, or for those looking for signs of ancient life.

"Just as on Earth, caves provide shelter from the elements, particularly dust storms and temperature extremes. On the red planet, they also protect from the rain of micro-meteorites, solar flares, ultraviolet radiation and high-energy particles from space," he said.

Such underground caverns might also harbour stable water ice, he added.
