They wanted to send the Martian helicopter on a record voyage, but it did not take off. The reason is named

On April 29, the Ingenuity mini-helicopter did not complete its planned fourth flight at Jezero Crater on Mars. This was announced by a mission operator at NASA’s Jet Propulsion Laboratory.

 

They write that the problem identified earlier is that every time the helicopter tries to take off, with a 15% probability, the watchdog timer will expire, and not go into flight mode.

“The current delay is in line with these expectations and does not hinder future flights,” added NASA. “The helicopter is fine. The findings indicate that it has not entered the required mode for the flight.”

The team is planning a new flight attempt for today, April 30th. The result will be known until 18:00 Kiev time.

The helicopter is planned to be raised by 5 m and sent to the south at a speed of ~ 3.5 m / s at a distance of ~ 84 m. Then it will turn back and land after a total of 133 m of flight. The voyage will take approximately 117 seconds.

Ingenuity uses counter-rotating coaxial propellers. Equipment – HD-camera and camera with solar tracker for navigation, data transmitter to the rover. It takes energy from solar panels. Up to five flights are planned. Weight 1.8 kg, height on supports 0.8 m, propeller diameter 1.2 m (up to ~ 2537 rpm), chassis volume 14 cm3, power 220 W, battery 35-40 Wh; flight time up to 90 s, radius up to 300 m, height up to 10 m; Max. speed: horizontal 10 m / s, vertical 3 m / s. Project cost ~ $ 85 million
