The U.S. “Witty” Mars helicopter encountered a failure in flight but fortunately landed safely.

The American Mars Helicopter “Witty” completed its sixth flight on Mars on the 27th. Due to a malfunction of the navigation system during the flight, the “wit” suffered a large and continuous shaking, but it landed safely.

According to NASA, the mission of “Gizwits” is to expand the flight envelope and demonstrate aerial imaging capabilities by taking three-dimensional images of specific areas.

According to the flight plan, after takeoff, the “Gizwit” rose to an altitude of about 10 meters, then moved 150 meters to the southwest, and then 15 meters to the south. During this process, images were taken, and then it flew for 50 meters to the northeast before landing and landing.

Telemetry technology showed that the first 150 meters of the “wit” flight were completed, but after that, its speed began to change, and it continued to tilt and shake. The onboard sensors showed that the “Wizwit” encountered a rollover and a large amount of power loss before landing safely.

Harford Gripp, the chief controller of the “wit” said that there are two main reasons why the “wit” can finally land safely. One is that its flight control system has sufficient stability; the other is in the final stage of its landing. Stop using the image navigation captured by the camera to ensure a smooth and continuous assessment of the movement status of the “wit” at this critical stage.

On February 18 this year, the “Wiz” landed on Mars with the “Perseverance” rover. It weighs about 1.8 kilograms and has four rotors. Solar panels charge the lithium battery. To fly in the thin Martian atmosphere, compared with helicopters flying on the earth, the rotors of the “wit” rotate at a much faster speed.
