USGS releases highly-detailed geologic map of Mars.

Our obsession with Mars continues, but that’s only because we’re learning so much more about it, thanks to scores of recent missions that involve the red planet. The U.S. Geological Survey (USGS) took 16 years worth of data about the planet and put that all together for this gorgeous map, which shows Mars’ geology. The data used came from a variety of Mars-oriented missions, like the Mars Global Surveyor, Mars Odyssey, Mars ExpressMars Reconnaissance Orbiter and Mars rover Curiosity. Sensors from those missions tell us that the surface of Mars is far older than we thought and also shows us a geologic activity that suggests the planet once sustained liquid water.
