Ancient Organics Discovered on Mars

Since arriving at Mars in 2012, NASA's Curiosity rover has drilled into rocks in search of organics molecules containing carbon. Organics are the building blocks of all life on Earth, though they can also come from non-living sources. The surface of Mars readily destroys these molecules, making them difficult to detect. Now, Curiosity has discovered ancient organics that have been preserved in rocks forbillions of years. This finding helps scientists better understand the habitability of early Mars, and it pavesthe way for future missions to the Red Planet.
