NASA 's Perseverance rover found a rock with features and chemistry that could have been produced by ancient microbial life on Mars .
Cheyava Falls rock is speckled with white spots with black rims, in which the rover's instruments detected iron phosphate molecules.
These features are a potential biosignature — intriguing signs that the rock was once home to conditions typically linked to microbial life.
The discovery of life beyond Earth is so profound, so paradigm-shifting, you have to get it right.
For the first time in our history of Mars exploration, we really have a good chance of being able to say something about whether there is evidence for ancient life on Mars or not.
When you bring samples back, depending on what they're made of, we should be able to tell something about when water was flowing on Mars .
Williams : "These samples will be revolutionary. They're volumetrically small, but their importance dwarfs their size" He predicts that if you bring a Mars sample home, scientific energy will turn in the direction of how you can separate out the gray areas of abiotic and biotic.
The rover is performing fantastic, says Williams .
