They might look like leopard spots, but to NASA the marks on a rock collected by the Mars Perseverance rover are the clearest sign yet of ancient life on Mars.
Scientists say it could possibly be a meteorite.
The Mars rover launched about three years ago and has been exploring the red planet for signs of life since then.
