Ingenuity Mars Helicopter damaged BOTH rotor blades during latest 72 flight: https://youtu.be/BhNnzmyvPcE . The rotor blades of the Ingenuity Mars helicopter are crafted from lightweight and durable carbon fiber composite to withstand the harsh Martian conditions. With four blades, each 1.2 meters long and 4 centimeters wide, arranged in counter-rotating coaxial rotors, they spin at 2,400 revolutions per minute due to Mars' thin atmosphere. To optimize lift in the low-density atmosphere, the blades are designed with a high angle of attack, tapered shape, and smooth surface to minimize drag. Their twist along the length helps distribute lift evenly and reduce torque on the rotor hub. Flexible hinges enable flapping motion for stability, while independent pitch control via a swashplate mechanism allows for intricate maneuvers. During latest flight 72 on Jan 18, 2024 Ingenuity helicopter grounded, damaged rotor blades. NASA ended the Ingenuity Mars Mission and performed this info on Jan 25, 2025.
