NASA stated on Thursday its Mars robotic helicopter Ingenuity, the primary automobile to realize powered, managed flight on one other world, has been grounded for good after flying dozens of instances over three years, ending a landmark mission that far exceeded all expectations.
The destiny of Ingenuity was sealed when imagery beamed again to Earth after its 72nd and last flight on Jan. 18 confirmed {that a} portion of one of many miniature whirligig’s twin rotor blades had damaged off, leaving it incapable of additional operation, NASA officers stated.
“It is bittersweet that I must announce that Ingenuity, the ‘little helicopter that could’ – and it kept saying, ‘I think I can, I think I can’ – well, it has now taken its last flight on Mars,” NASA Administrator Bill Nelson stated in a video posted on social media.
What was deliberate as a 30-day know-how demonstration of not more than 5 brief flights ended up stretching properly past the expectations of engineers who designed and constructed the helicopter at NASA’s Jet Propulsion Laboratory (JPL) close to Los Angeles.

NASA’s Ingenuity Mars helicopter has made its last flight after sustaining harm to “one or more” of its rotor blades, the US area company stated on January 25, 2024. The mini-aircraft made historical past by attaining the primary powered, managed flight on one other planet on April 19, 2021, and the final of its 72 flights came about on January 18, a press release stated.

Ingenuity finally buzzed over the Martian terrain 14 instances farther than initially deliberate, logging greater than two hours, eight minutes of flight time and protecting a distance of 10.5 miles (17 km) by way of all 72 flights. Its peak altitude was measured at 78.7 toes (24 meters).
The rotor-craft was carried to the Red Planet strapped to the stomach of NASA’s Perseverance rover, which landed three years in the past on the ground of an enormous Martian basin known as Jezero Crater on a separate mission aimed primarily at accumulating floor samples for eventual return to Earth.

When the 4-pound (1.8-kg) rotor craft carried out its modest, debut takeoff and touchdown within the skinny Martian ambiance on April 19, 2021 – a flight of 39 seconds – it was hailed as an seminal feat of interplanetary aviation.

NASA likened Ingenuity’s achievement at Jezero Crater to the historic first managed flight of the Wright brothers’ motor-driven airplane close to Kitty Hawk, North Carolina, in December 1903.
Over time, JPL continued to ship the helicopter on progressively extra bold flights, pushing its capabilities.
The finish got here after JPL groups started flying Ingenuity into a very barren, featureless space of Mars, testing the bounds of an auto-navigational system that will depend on seen landmarks for aviation steerage, in line with Teddy Tzanetos, JPL’s Ingenuity venture supervisor.
The U.S. area company stated Ingenuity made an “emergency landing” throughout what turned its penultimate flight on Jan. 6, apparently setting itself down extra abruptly than deliberate as a result of navigational disorientation.
When JPL controllers sought to carry out a brief, vertical flight 12 days later to find out Ingenuity’s location, information exhibits it rose off the bottom, hovered briefly, then started a descent earlier than shedding contact with the rover, which serves as its communications relay with Earth.
(*72*) the helicopter despatched days later captured the shadow of its broken rotor blade, apparently damaged throughout its last landing, Tzanetos instructed reporters.
Engineers imagine steerage difficulties posed by the “bland” terrain the place Ingenuity was flying resulted in a lack of equilibrium that prompted the automobile to instantly tilt or transfer sideways, which in flip led to the rotors hanging the floor, Tzanetos stated.
Ingenuity, resembling a field with 4 legs and parasol of rotor blades and photo voltaic panel, will stay out its last days idle however emitting periodic blips of knowledge earlier than shedding contact with the rover as Perseverance strikes farther away.
Still, NASA officers celebrated Ingenuity’s exploits as paving the way in which for a brand new mode of aerial exploration on Mars and elsewhere within the photo voltaic system, reminiscent of Saturn’s moon Titan, for which a rotor-craft known as Dragonfly is beneath improvement.
Building a helicopter to fly on Mars posed main engineering hurdles.
While Mars possesses a lot much less gravity to beat than Earth, its ambiance is just one% as dense, making it particularly exhausting to realize aerodynamic elevate. Thus, Ingenuity was fitted with rotor blades which are bigger and spin way more quickly than can be wanted on Earth for the same craft of its measurement.
The small, light-weight automobile additionally needed to face up to punishing chilly, with nighttime temperatures dipping as little as 130 levels under zero Fahrenheit (minus 90 Celsius).
Engineers will run last checks on Ingenuity and obtain remaining photographs from its onboard laptop, NASA stated.
