New findings from NASA’s Curiosity rover provide evidence that suggest Mars could have once sustained organic life.
According to NASA, “tough” organic molecules containing carbon and hydrogen have been found inside three-billion-year-old sedimentary rocks known as mudstone, located inside Gale Crater. A press release from NASA notes that while these organic molecules might suggest life, they are not definitive proof of life.
Curiosity has not yet determined the origins of the molecules, but past data has suggested that the site of its find, Gale Crater, was once host to a lake on the surface of Mars billions of years ago. A liquid lake like the one in question would have held the “ingredients” to sustain life, according to scientists.
