Mars is infested with robots, orbiting the planet and roaming the Martian surface on a mission to uncover its secrets; now, Perseverance joins this dedicated group of machines to uncover if there is, or was ever, life on the Red Planet.

Past missions suggest that Mars was once a very different world. The Mars we see today has completely changed from the Mars of a few billion years ago.
