NASA's Ingenuity Mission Is Over (nasa.gov) 73

cusco writes: After three years and 72 flights of its 5-flight mission the mission of the Ingenuity helicopter on Mars is finally over. Images show that Ingenuity suffered damage to one of its rotor blades and will not be able to take off again. NASA's press release, also shared by cusco: Ingenuity landed on Mars Feb. 18, 2021, attached to the belly of NASA's Perseverance rover and first lifted off the Martian surface on April 19, proving that powered, controlled flight on Mars was possible. After notching another four flights, it embarked on a new mission as an operations demonstration, serving as an aerial scout for Perseverance scientists and rover drivers. In 2023, the helicopter executed two successful flight tests that further expanded the team's knowledge of its aerodynamic limits.

[...] Over an extended mission that lasted for almost 1,000 Martian days, more than 33 times longer than originally planned, Ingenuity was upgraded with the ability to autonomously choose landing sites in treacherous terrain, dealt with a dead sensor, cleaned itself after dust storms, operated from 48 different airfields, performed three emergency landings, and survived a frigid Martian winter.

Designed to operate in spring, Ingenuity was unable to power its heaters throughout the night during the coldest parts of winter, resulting in the flight computer periodically freezing and resetting. These power "brownouts" required the team to redesign Ingenuity's winter operations in order to keep flying.

With flight operations now concluded, the Ingenuity team will perform final tests on helicopter systems and download the remaining imagery and data in Ingenuity's onboard memory. The Perseverance rover is currently too far away to attempt to image the helicopter at its final airfield.

    Sadly, the environment will not keep it intact, but we'll remember it fondly.

    This is a sad day, but the mini robot did a great job over there.

    It was the first time we flew something on Mars. At first, noone was sure it would even properly unfold and set up, let alone work. But it worked beyond its most optimistic mission parameters.

    Did I wish it continued forever? Yes.
    But everything has an end.

    The good thing is, its success will enable future missions to have more and better flying machines over there.

    It sure looks like something bit off the end of that rotor blade...

    Exactly one human being is known to have been alive for both the Wright Flyer's first flight and Ingenuity's.

    Kane Takana [wikipedia.org] was 11 months old when Orville first took off; and 118 years old when Ingenuity first took off. She passed away on the first anniversary of its maiden flight.

    Ingenuity - overengineered to near perfection. Completed 72 out of 5 planned missions! I love to learn about it, even though it leaves me somewhat disappointed when I get back to our every day devices, cars, apps, etc. Mass production - race to market engineering done by people who do it for a paycheck, rather than because they are passionate about it. For example, think how good out EV's or the charging infrastructure would be if it was designed by people with a passion for engineering, user experience design, etc. Tesla came the closest, as Elon insisted on hiring geeks (he burned them out quick, but they still lasted 1-3 years and while never wanting to do it again, do not regret their experience there). This is probably the reason all other car companies abandoned their charging infrastructure engineering and all agreed to use Tesla's - geeks just do it so much better. Now think about all the other products which malfunction every day you use them, or simply work in a way which makes you think "who designed this and what were they thinking?!?".

      I wonder how many more missions that run 10 times the expected lifetime NASA has to do before certain people give up on the whole "only private companies can do anything right" thing.

      It reminds me of the Opportunity rover, which ran for 5,111 days of its 90-day mission.

        Or Voyager, which was only funded as far as Saturn, or Hubble, which was supposed to be replaced with a more modern telescope after a decade, or Sojourner, which was designed for 7 days and lasted 95, or Galileo which was finally deorbited 8 years after entering Jupiter orbit, or . . .

      Ingenuity - overengineered to near perfection.

      I wouldn't say overengineered. It was largely using commodity parts. The visual navigation was done on a Qualcomm Snapdragon 801 - little different than a Samsung smartphone from 5-10 years ago - definitely not space-rated! The altimeter was a Garmin LIDAR product that you can buy from Sparkfun Electronics [sparkfun.com]. The IMU was built around a Bosch BMI-160 - typically found in smartphones. The cameras (color for interesting stuff, B&W for navigation) were like

      • Overengineered does not have to mean using expensive parts. You could overengineer a paper airplane. It just means works well beyond the minimum viable product envelope. You do have a point that a technology demonstrator being easier to overengineer, as it is ultra low volume (a lot less users to consider, no volume manufacturing engineering).

    Sigh. I always get disappointed watching and listening to Bill Nelson as NASA administrator.

    For my money, I'd much rather have the deputy director, Pam Melroy, have the lead job. She came up through the Air Force as a test pilot, is a combat veteran, worked in the Columbia accident recovery and investigation teams, was Shuttle pilot on two flights, and Shuttle commander on a third flight.

    I suppose as a political appointee for a high-profile government agency, it makes sense to have a political animal in that role: a well-connected Beltway insider, a Congressman who managed to bully his way onto a Shuttle flight, followed by a long stint as Senator. Maybe it's best to have the politician out in front, while the more qualified deputy tries to get things done out of the spotlight.

    I regularly fly R/C coaxial-rotor things with entire blades missing (quadcopters too). It just takes some software tweaking if your flight controller isn't very good. If it is good then you don't need to do anything, it just works and the microcontroller can compensate for the imbalance. This was part of my research before building rescue craft so I could make sure they could continue to work even if damaged.

    Sounds like they just need better software developers to get it back in the air.

      Keep in mind that Ingenuity was designed in 2014, and had to use hardware able to exist in the radiation of transit and on the surface. The CPU for example is a Qualcomm Snapdragon 801 processor, which not only has to run the avionics and cameras and do the navigation and recognize a safe landing place, etc. There's not a lot of room for flexibility in hardware that old, plus it's running Linux rather than a custom OS so there's that overhead as well. By the time a fix could be designed that squeezed in

  • Are they saying it was too cold to fly, they did it anyway, then the computer lost power, reset, and it crashed, losing the asset for all time?

    I mean, it wasn't O-rings this time, but come on, NASA!

    • by cusco ( 717999 )

      No, you misunderstand. It wasn't designed to survive the cold nights of the Martian winters, which would have required auxiliary heaters that the solar panel and batteries couldn't support. That it did was a big surprise, and an important finding for future missions. They aren't sure yet what caused the damage to the rotor, they can still communicate just fine with the craft but the damage is extensive enough that it will never lift off again.
