For the last of our month-of-Sputnik space art posts, here’s more imagery of the hematite plains of Mars.
This false-color infrared image from the Thermal Emission Imaging System (THEMIS) on NASA’s Mars Odyssey orbiter shows the presence of hematite – a kind of iron oxide indicating the presence of water – on a section of Meridiani Planum, about 400 kilometers northeast of where the rover Opportunity landed.
