Mars Perseverance and Ingenuity

Mars Perseverance and Ingenuity transformed planetary exploration in 2021: Perseverance landed in Jezero Crater to cache 43 sample tubes for future return, while Ingenuity achieved the first powered flight on another planet, logging 59 flights over 11 miles. The helicopter spun its rotors at 2,537 RPM—five times faster than Earth's typical drone—proving controlled flight viable in Mars's thin 1% atmosphere.
