NASA’s Ingenuity Mars Helicopter Reaches a Total of 30 Minutes Aloft
With its recent 17th flight, the Red Planet rotorcraft reaches an airborne milestone the team never considered achievable.
The 17th flight of NASA’s Ingenuity Mars Helicopter on December 5 pushed the total flight time past the 30-minute mark. The 117-second sortie brought history’s first aircraft to operate from the surface of another world closer to its original airfield, “Wright Brothers Field,” where it will await the arrival of the agency’s Perseverance Mars rover, currently exploring “South Séítah” region of Mars’ Jezero Crater.
Along with accumulating 30 minutes and 48 seconds of flight time, the trailblazing helicopter has traveled over the surface a distance of 2.2 miles (3,592 meters), flying as high as 40 feet (12 meters) and as fast as 10 mph (5 meters per second).
The rotorcraft’s status after the December 5 flight was previously unconfirmed due to an unexpected cutoff to the in-flight data stream as the helicopter descended toward the surface at the conclusion of its flight. Perseverance serves as the helicopter’s communications base station with controllers on Earth. A handful of data radio packets the rover received later suggested a healthy helicopter on the surface but did not provide enough information for the team to declare a flight success.
But data downlinked to mission engineers at NASA’s Jet Propulsion Laboratory in Southern California on Friday, December 10, indicates that Flight 17 was a success and that Ingenuity is in excellent condition.
The 30-minute mark far surpasses the original plans for the 4-pound (1.8-kilogram) rotorcraft. Designed as a technology demonstration to perform up to five experimental test flights, Ingenuity first flew on April 19, 2021, with a short up-and-down hop to prove powered, controlled flight on Mars was possible. The next four experimental flights expanded the rotorcraft’s flight envelope, making increasingly longer flights with more complicated maneuvering, which further helped engineers at JPL better understand its performance.
With the sixth flight, the helicopter embarked on a new operations demonstration phase, investigating how aerial scouting and other functions could benefit future exploration of Mars and other worlds. In this new chapter, the helicopter has operated from airfields well south of Wright Brothers Field, scouting rocky outcrops and other geologic features of interest to the Perseverance rover’s science team.
“Few thought we would make it to flight one, fewer still to five. And no one thought we would make it this far,” said Ingenuity Team Lead Teddy Tzanetos of JPL. “On the way to accumulating over a half-hour aloft Ingenuity has survived eight months of bitter cold, and operated out of nine unique Martian airfields. The aircraft’s continued operations speaks to the robustness the design and the diligence and passion of our small operations team.”
Flight 18 is scheduled for Ingenuity to cover another 754 feet (230 meters) at a speed of 5.6 mph (2.5 meters per second) over 125 seconds. The new airfield, close to the northern boundary of Séítah, will be the rotorcraft’s 10th on Mars.
As with the previous effort, Flight 18 will push the limits of Ingenuity’s radio range and performance. To provide it with the best chance of maintaining a link throughout landing, the Mars Helicopter team has modified the flight sequence to communicate in a low-data-rate mode, which will provide an additional signal-strength boost to the radio link.
“If we do lose radio link on landing, it may be several days or weeks until the line-of-sight between Ingenuity and Perseverance improves enough to attempt a communication session,” said Tzanetos. “While delaying our post-flight data analysis is an inconvenience, it is not unexpected and becoming the new normal as we continue to operate in challenging terrain in the weeks ahead.”
More About Ingenuity
The Ingenuity Mars Helicopter was built by JPL, which also manages this technology demonstration project for NASA Headquarters. It is supported by NASA’s Science, Aeronautics, and Space Technology mission directorates. 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 in designed and manufactured the Mars Helicopter Delivery System.
At NASA Headquarters, Dave Lavery is the program executive for the Ingenuity Mars Helicopter.
More About Perseverance
A key objective for Perseverance’s mission on Mars is astrobiology, including the search for signs of ancient microbial life. The rover will characterize the planet’s geology and past climate, pave the way for human exploration of the Red Planet, and be the first mission to collect and cache Martian rock and regolith (broken rock and dust).
Subsequent NASA missions, in cooperation with ESA (European Space Agency), would send spacecraft to Mars to collect these sealed samples from the surface and return them to Earth for in-depth analysis.
The Mars 2020 Perseverance mission is part of NASA’s Moon to Mars exploration approach, which includes Artemis missions to the Moon that will help prepare for human exploration of the Red Planet.
