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.
Our neighbor, Mars, fascinates us. It's a planet that is similar to Earth but with some big differences. Mars is rusty, dusty, frigid, and frozen. 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. Without a time machine to explore ancient Mars, we employ a team of high-tech robot investigators, an entire fleet of robotic spacecraft exploring the planet. Working together, they dig into Mars's past to answer the ultimate question -- did Mars once have life?
