We’ve known for a decade or more that there is water, albeit frozen, on Mars. Now, a new analysis of satellite images reveals the whereabouts of eight substantial ice deposits. The US Geological Survey has published the findings in the journal Science, saying that there’s ice under a third of the surface of Mars. Some of the ice is just a few feet below the surface, while other deposits are under 300 feet of rocks and dust. This is important information for those who are working on sending humans to Mars. It could also be a trove of information about the climate history of the red planet. We talk with the lead author of the study, USGS scientist Colin Dundas.
