A groundbreaking new study has indicated that there could be habitable salt glaciers situated beneath the planet's surface.
The ice, which is thought to descend almost 330ft, could help to support a future manned presence on Mars.
A 'vortex' of cold air over the Karakoram mountain range has been causing glaciers to continue growing.
A secret US facility hidden beneath the ice is believed to contain significant amounts of nuclear waste.
The Red Planet is home to a large volume of glacial ice buried beneath a layer of surface dust.
