NASA has successfully conducted tests for future Mars helicopter designs on two different planets. These tests included advanced rotor examinations on Earth, as well as exceptional flights by the Ingenuity Mars Helicopter. This innovative work in rotorcraft technology is improving our understanding of flight under varying atmospheric conditions, representing a crucial advancement in Mars exploration.

Engineers are pushing the limits to enhance the performance of future Mars helicopters.
For the first time, Earth and Mars have been utilized simultaneously for aircraft design testing. At NASA’s Jet Propulsion Laboratory (JPL) in Southern California, a new rotor for potential use in upcoming Mars helicopters was tested, achieving near-supersonic speeds (0.95 Mach). Concurrently, the Ingenuity Mars Helicopter on Mars set new records in altitude and speed for experimental flight testing.

Ingenuity: Linking Earth and Mars
Teddy Tzanetos, the project manager for Ingenuity and Mars Sample Recovery Helicopters, explains, “Our testing of the next-generation Mars helicopter literally enjoys the best of both worlds. Earth offers extensive instrumentation and direct interaction for testing new aircraft components. Mars, on the other hand, provides authentic extraterrestrial conditions unreplicable on Earth, including a thin atmosphere and lower gravity.”
Advanced Rotor Technology for Mars Missions
New carbon fiber rotor blades, tested on Earth, are nearly 4 inches longer than those of Ingenuity, with increased strength and a unique design. These blades might enable larger, more proficient Mars helicopters. However, as blade tips near supersonic speeds, managing the resulting vibration and turbulence becomes a significant challenge.
Simulating Martian Conditions on Earth
Engineers turned to JPL’s massive 25-foot by 85-foot space simulator, which previously served the Surveyor, Voyager, and Cassini missions, to recreate Martian conditions on Earth. Over three weeks in September, a team closely monitored sensors, meters, and cameras as the blades were tested at increasing speeds and pitches.

Tyler Del Sesto, Sample Recovery Helicopter deputy test conductor at JPL, mentioned, “We accelerated our blades to 3,500 rpm, 750 revolutions per minute faster than Ingenuity’s blades. These efficient blades are now more than theoretical; they are flight-ready.”
Simultaneously, about 100 million miles away, Ingenuity was performing maneuvers beyond initial expectations.
Ingenuity’s Remarkable Achievements
Initially intended for a maximum of five flights, Ingenuity has now flown 66 times, far surpassing its planned 30-day mission. These flights have provided unprecedented perspectives and data, with the team pushing Ingenuity to new limits in speed and altitude.
Håvard Grip, the chief pilot for Ingenuity, records each flight in The Nominal Pilot’s Logbook for Planets and Moons. Notable achievements include doubling the maximum airspeed and altitude, enhancing acceleration rates, and experimenting with slower landing speeds.
Facing Martian Flight Challenges
Ingenuity’s flights, constrained by energy and motor temperature, typically last two to three minutes. To cover more ground, the team has been instructing Ingenuity to fly at higher altitudes, allowing for longer visibility of ground features, essential for its navigation system. Flight 61 set a new altitude record, and Flight 62 established a speed record, aiding in scouting locations for the Perseverance rover.
Future Prospects for Ingenuity
Ingenuity will continue its groundbreaking flights, with plans for high-speed tests and special maneuvers to refine data on rotorcraft performance on Mars.
Travis Brown, Ingenuity’s chief engineer at JPL, emphasized the importance of this data for future Mars helicopter designs, acknowledging the unique challenges of remote operation.
More About Ingenuity
Originally a technology demonstration, Ingenuity’s initial flight on Mars was on April 19, 2021. It has since transitioned to demonstrating aerial scouting’s potential for future Mars and interplanetary exploration.
The Ingenuity Mars Helicopter project, managed by JPL for NASA Headquarters, involves significant contributions from NASA’s Ames and Langley Research Centers, as well as collaboration with AeroVironment Inc., Qualcomm, SolAero, and Lockheed Space. Dave Lavery at NASA Headquarters serves as the program executive for the project.
