NASA's Ingenuity helicopter, the first powered and controlled aircraft to take flight on another planet, survived a "stressful" navigation glitch that sent it oscillating off-course during a cosmic flight on Mars.
The chopper, which arrived on the red planet strapped to the Perseverance Rover in February, took to the air for its sixth test flight last Saturday when an anomaly occurred that led it on an unexpected flight path, engineers at NASA's Jet Propulsion Laboratory (JPL) said on Thursday.
