Unlike its predecessor Curiosity, NASA’s Perseverance rover is explicitly intended to “search for potential evidence of past life,” according to the official mission objectives.
For more than two years, NASA’s Perseverance rover has been roaming Mars, drilling for rock samples that may hold clues to ancient life on the Red Planet, but the six-wheeled robot can only travel so far. Luckily, the rover recently got some extra help from a river that once flowed on the surface of Mars.
