NASA's Perseverance rover successfully lands on Mars, bridging 300 million miles and 'seven minutes of terror' before touching down. After completing the months-long journey, the rover landed on Mars with the "Explicit goal of searching for signs of ancient life," according to NASA. After about three months of equipment checkouts, the 10-foot vehicle will then roam the surface at 0.1 mph, looking for answers to science's oldest questions. Ref. USAToday.
