NASA’s Ingenuity Mars Helicopter Completes 50th Flight
The history-making rotorcraft has recently been negotiating some of the most hazardous terrain it’s encountered on the Red Planet.
NASA’s Ingenuity Mars Helicopter has completed its 50th flight on Mars. The first aircraft on another world reached the half-century mark on April 13, traveling over 1,057.09 feet (322.2 meters) in 145.7 seconds. The helicopter also achieved a new altitude record of 59 feet (18 meters) before alighting near the half-mile-wide (800-meter-wide) “Belva Crater.”With Flight 50 in the missionlogbook, the helicopter team plans to perform another repositioning flight before exploring the “Fall River Pass” region of Jezero Crater.“Just as the Wright brothers continued their experiments well after that momentous day at Kitty Hawk in 1903, the Ingenuity team continues to pursue and learn from the flight operations of the first aircraft on another world,” said Lori Glaze, director of the Planetary Science Division at NASA Headquarters in Washington.NASA’s Ingenuity Mars helicopter made history when it achieved the first powered, controlled flight on another planet on April 19, 2021. A little less than two years later, on April 13, 2023, it completed its 50th flight.

Designed as a technology demonstration that would fly no more than five times, the helicopter was intended to prove powered, controlled flight on another planet was possible. But Ingenuity exceeded expectations and transitioned into being anoperations demonstration.Every time Ingenuity goes airborne, it covers new ground and offers a perspective no previous planetary mission could achieve. Imagery from the helicopter has not only demonstrated how aircraft could serve as forward scouts for future planetary expeditions, but it has even come in handy for thePerseveranceteam.Teddy Tzanetos at NASA’s Jet Propulsion Laboratory provides an update on the agency’s Ingenuity Mars Helicopter and discusses how it’s inspiring future aerial exploration of the Red Planet.Credit: NASA/JPL-CaltechBy testing the helicopter’s limits, engineers are gathering flight data that can be used by engineers working on designs for possible future Mars helicopters. That includes the people designing the Mars Sample Return campaign’s proposedSample Recovery Helicopters.Riskier TerrainSince leaving the relatively flat confines of Jezero Crater’s floor on Jan. 19, Ingenuity has flown 11 times, setting new speed and altitude records of 14.5 mph (6.5 meters per second) and 59 feet (18 meters) along the way.Although the deep chill of winter and regional dust events (which can block the Sun’s rays from reaching the helicopter’s solar panel) have abated, Ingenuity continues tobrown outat night. As a result, theHelicopter Base Stationon the rover needs to search for the rotorcraft’s signal each morning at the time Ingenuity is predicted to wake up. And when the helicopter does fly, it now must navigate rugged and relatively uncharted terrain, landing in spots that can be surrounded by hazards.NASA’s Ingenuity Mars Helicopter is seen here at the starting point of its 47th flight on Mars.

And while we recently upgraded the navigation software onboard to help determine safe airfields, every flight is still a white-knuckler.”Frequent FlyerBeyond facing more challenging terrain, Ingenuity will also fly at a greater frequency in the coming days because the helicopter needs to remain within electronic earshot of the rover. With itsAutoNav capability, Perseverance can travel hundreds of meters each day.“Ingenuity relies on Perseverance to act as a communications relay between it and mission controllers here at JPL,” said Anderson. “If the rover gets too far ahead or disappears behind a hill, we could lose communications. The rover team has a job to do and a schedule to keep. So it’s imperative Ingenuity keeps up and is in the lead whenever possible.”Perseverance recently completed exploring “Foel Drygarn,” a scientific target that may containhydrated silica(which is of strong astrobiological interest). It is currently headed to “Mount Julian,” which will provide a panoramic view into nearby Belva Crater.Feats of IngenuityBuilt with many off-the-shelf components, such as smartphone processors and cameras, Ingenuity is now 23 Earth months and 45 flights beyond its expected lifetime. The rotorcraft has flown for over 89 minutes and more than 7.1 miles (11.6 kilometers).“When we first flew, we thought we would be incredibly lucky to eke out five flights,” said Teddy Tzanetos, Ingenuity team lead at JPL. “We have exceeded our expected cumulative flight time since our technology demonstration wrapped by 1,250% and expected distance flown by 2,214%.”Surpassing expectations like this comes at a cost, however. With some helicopter components showing signs of wear and the terrain becoming more challenging, the Ingenuity team recognizes that every great mission must eventually come to an end. “We have come so far, and we want to go farther,” said Tzanetos. “But we have known since the very beginning our time at Mars was limited, and every operational day is a blessing. Whether Ingenuity’s mission ends tomorrow, next week, or months from now is something no one can predict at present. What I can predict is that when it does, we’ll have one heck of a party.”More About IngenuityThe Ingenuity Mars Helicopter was built by JPL, which also manages the project for NASA Headquarters. It is supported by NASA’s Science Mission Directorate. NASA’s Ames Research Center in California’s Silicon Valley and NASA’s Langley Research Center in Hampton, Virginia, provided significant flight performance analysis and technical assistance during Ingenuity’s development. AeroVironment Inc., Qualcomm, and SolAero also provided design assistance and major vehicle components. Lockheed Space designed and manufactured theMars Helicopter Delivery System.At NASA Headquarters, Dave Lavery is the program executive for the Ingenuity Mars Helicopter.
