The mini rotorcraft, which hitched a ride to the Red Planet with the Perseverance rover in early 2021, has already survived well beyond its initial 30-day mission to prove the feasibility of its technology in five test flights. Since then, it has been deployed dozens of times, acting as an aerial scout to assist its wheeled companion in searching for signs of ancient microbial life from billions of years ago, when Mars was much wetter and warmer than today.
