In summer 2024, the rover collected a sample from the “Chevaya Falls” rock which was found to have potential biosignatures — clues that suggest past life may have been present, but that require more data or further study before any conclusions about the absence or presence of life.

In addition to making discoveries on Mars, the rover itself is demonstrating technogical advances: A new technology developed at NASA’s Jet Propulsion Laboratory in Southern California enables Perseverance to figure out its whereabouts without calling humans for help. Dubbed
