Ice geysers 'discovered on Mars'

[Rick]

Geysers spewing sand and dust hundreds of feet into the air have been discovered on Mars, scientists say.

Images from a camera orbiting Mars have shown the 100mph jets of carbon dioxide erupt through ice at the planet's south pole, Arizona State University says.

The orbiting camera, called the Thermal Emission Imaging System (Themis), is on the Mars Odyssey probe.
