  • Two spacecraft orbiting Mars have discovered water frost atop towering volcanoes near the Red Planet's equator.
  • They found the frost on the Tharsis volcanoes, the tallest volcanoes in the Solar System.
  • The frost is only as thick as a human hair - about one-hundredth of a millimetre thick - but covers a vast area.
  • This amounts to about 150,000 tonnes of water freezing and evaporating during the cold seasons on Mars.
  • It is equivalent to roughly 60 Olympic swimming pools.
  • The Tharsis region of Mars is home to numerous volcanoes.
  • It is including the Olympus Mons, and the Tharsis Montes: Ascraeus, Pavonis and Arsia Mons.
  • Many of the volcanoes in this region are as big as or much bigger than Mount Everest on Earth.
  • Olympus Mons is three times as tall as Everest.
