This doesn’t mean that Mars has organic, carbon-based life. In fact, NASA has an idea that this came from previous missions on Mars’ surface, but the fact of the matter is that several organic comounds were found on Mars. What’s Mars made of? Well, after scooping up some loose sand, Curiosity’s Sample Analysis at Mars (SAM) suite and the Chemistry and Mineralogy (CheMin) instruments found a couple of chemicals, including sulfur, chlorine, and traces of carbon-based materials.
NASA will continue to work to determine of the carbons Curiosity detected are actually indigenous to Mars, and not something that slipped off of the Curiosity rover and into the sand by conducting a drill test before the rover travels to Mount Sharp early next year.
