The Ingenuity helicopter achieved a lot in its almost three years on Mars. | Supply: NASA/JPL-Caltech
The Ingenuity helicopter, the primary ever plane to fly on one other planet, ended its almost three-year journey on Mars, stated NASA yesterday. The helicopter, initially meant as a expertise demonstration, has surpassed all of NASA’s expectations and accomplished dozens extra flights than initially deliberate.
Whereas the Ingenuity stays upright and in communication with floor controllers, it won’t be able to fly once more. NASA acquired pictures of its Jan. 18 flight this week displaying that a number of of its rotor blades had sustained harm throughout touchdown, making the helicopter not able to flight.
“The historic journey of Ingenuity, the primary plane on one other planet, has come to finish,” stated NASA Administrator Invoice Nelson in a launch. “That exceptional helicopter flew greater and farther than we ever imagined and helped NASA do what we do greatest – make the inconceivable, doable. Via missions like Ingenuity, NASA is paving the way in which for future flight in our photo voltaic system and smarter, safer human exploration to Mars and past.”
On Jan. 18, Ingenuity’s staff deliberate for the helicopter to make a brief vertical flight to find out its location. The helicopter had executed an emergency touchdown on its earlier flight, leaving NASA’s engineers not sure of precisely the place it touched floor.
NASA’s knowledge reveals that, because it had deliberate, the helicopter rose to a most peak of 40 ft. (12 m) and hovered for 4.5 seconds earlier than beginning its descent at a velocity of three.3 toes per second (1 meter per second). At about 3 ft. (1 m) above the Martian floor, Ingenuity misplaced communication with the Perseverance rover, which serves as a communications relay for the helicopter.
Ingenuity’s staff reestablished communications with the helicopter the next day, and NASA Jet Propulsion Laboratory (JPL) was in a position to collect extra details about the flight. A number of days later, new pictures confirmed {that a} rotor blade had been broken.
The staff remains to be investigating the reason for the communications dropout and the helicopter’s orientation when it touched down.

Ingenuity survived the journey to Mars
When Ingenuity began its journey on Mars, strapped to the stomach of the Perseverance rover, NASA hoped it might carry out a minimum of 5 experimental check flights over 30 days. It first lifted off the Martian floor on April 19, 2021, proving that powered, managed flight on one other planet was doable. It was not designed to hold payloads or execute different missions.
After finishing its preliminary mission, Ingenuity grew to become an operations demonstration. Throughout this part, it served as an aerial scout for Perseverance scientists and rover drivers. In 2023, the helicopter expanded NASA‘s data of its aerodynamic limits when it accomplished two profitable flight exams.
“At NASA JPL, innovation is on the coronary heart of what we do,” said Laurie Leshin, director of NASA JPL. “Ingenuity is an exemplar of the way in which we push the boundaries of what’s doable day by day. I’m extremely happy with our staff behind this historic technological achievement and wanting to see what they’ll invent subsequent.”
Helicopter pushed the boundaries of flight on Mars
Ultimately, Ingenuity’s mission lasted virtually 1,000 sols (Martian days or 24 hours, 39 minutes, 35 seconds), greater than 33 occasions longer than NASA initially deliberate. Due to this, Ingenuity’s staff needed to continuously innovate to maintain the helicopter working so long as doable.
Whereas on Mars, Ingenuity was upgraded with the power to autonomously select touchdown websites in treacherous terrain. It additionally handled useless sensors, cleaned itself after mud storms, operated from 48 completely different airfields, carried out three emergency landings, and survived a Marian winter.
The helicopter was solely designed to outlive throughout spring. To maintain it working via the coldest elements of winter, Ingentity powered its heaters all through the evening. This, nonetheless, brought about the flight laptop to periodically freeze and reset. These energy “brownouts,” as NASA known as them, pushed the staff to revamp Ingenuity’s winter operations to stick with it and working.
In its almost three years on Mars, the Ingenuity helicopter carried out 72 flights, flew greater than 14 occasions farther than deliberate, and logged greater than two hours of complete flight time.
Now that flight operations have concluded, the Ingenuity staff will carry out remaining exams on the helicopter’s techniques and obtain the remaining imagery and knowledge in Ingenuity’s onboard reminiscence. Proper now, the Perseverance rover is simply too distant for it to seize pictures of the helicopter at its remaining airfield.
