Did you know that the Mars rover, Curiosity, recently discovered that Mars once had all the building blocks of life on its surface? It’s true!
The rover was able to drill into a rock, the first time a robot has ever drilled on another planet, and perform a chemical analysis of what it found. What it discovered was carbon, nitrogen, hydrogen, oxygen, phosphorus and sulfur. Scientists believe that microbes could’ve lived, and possibly flourished, in Mars’ environment at some point. They also believe there was water there as well.
While they’ve yet to discover any actual organic molecules, this is the first example scientists have of an extraterrestrial environment that was once capable of supporting life. Though it’s been stated that Curiosity’s mission isn’t specifically to find past or current life, the possibilities are no less exciting!
