If signs of life really do exist on Mars, there's a chance the Perseverance rover has already rolled over them.

Already, Percy has drilled and captured several sediment samples from this very region. Its inventory is 60 percent full.

Some of the rocks and dust Percy has collected even show intriguing signs of organic compounds. But until a mission is sent to collect the fruits of the rover’s labor, it’s impossible to say if these compounds come from biological or geological sources.
