back to article You can listen right here to the whir of a robot helicopter flying on an alien world

One of the microphones on Perseverance, NASA’s latest and greatest Mars rover, has recorded the sounds of its autonomous helicopter Ingenuity flying on the Red Planet, providing scientists with the first ever audio samples of an aircraft operating on another planet. You can hear the recording in the video below. Make sure to …

      If you listen really carefully, you can hear the Ride of the Valkyries coming out of the helicopter's speakers.

        That would be Golden Earring's Radar Love, Shirley, followed immediately by Twilight Zone.

        Or perhaps the 9 minute live version of Frankenstein featuring both Winter brothers, recorded in Copenhagen(??) in ~1970 before the tune even had a name. Raw. Awesome. Find a copy. Listen to it. Really.

    The idea of a little helicopter flying around on Mars is just so utterly charming. I can't help but smile every time I see the videos.

    It's lovely to see it take off, then move horizontally, bravely disappearing out of camera range, then waiting patiently - and there it is, back again, to where it started. You almost feel that it's proud of its achievement !

      OK, I was being a bit sentimental, I agree. But to be downvoted for that? Really?

    "Sounds below 80Hz and above 90Hz have been turned down in volume"

    Almost disappointed. I think I would prefer listening to the actual recording.

    Don't misunderstand me, this was another awesome video, but I would like to hear what is really happening, not just what NASA wants me to hear.

    The untouched audio is reality. This is great, but I prefer reality.

      I'd like to listen to the unfiltered track as well but suspect that you'd need to listen very carefully and have some quality speaker or better headphone.

        Yes, but you'd probably need to adjust your audio settings to erm... filter sounds below 80 Hz and above 90 Hz. I'll get my cost.

      I agree this is adds a new dimension to our experience of Mars.

      My concern is that we will only hear the fundamental component of the complex waveform without the harmonics, so it is bound to sound like a sine wave.

      What I really want to hear next is the Doppler shift as the helicopter does a close fly-by. Just hope that the resulting sound isn't beyond the limits of the filter.

      Re: "Sounds below 80Hz and above 90Hz have been turned down in volume"

      Well it is pretty far away and the atmosphere is VERY thin. Maybe if they do a flight where it is only 20 feet away they won't need to filter out the background noise so much.

      Re: "Sounds below 80Hz and above 90Hz have been turned down in volume"

      That's interesting, because the Martian police growlers on their cars are very low pitch and Martian voices are rarely lower pitched than about 100Hz.

      I suspect the filtering is due to the embarrassment at being nicked for parking and flying in a slither only zone, so soon after landing.

    Ho hum

    and its own machinery cranking away as it drives around the Jezero crater

    One of the nicest things about all the recent lockdowns, particularly the first one, has been the quiet. I've been able to sit outside in the sun, and listen to the wind in the trees, the birds, the stream, the animals - and minutes pass without any mechanical sounds at all. No cars, lorries, revving motorbikes, airliners, chain-saws, lawn-mowers, strimmers.

    So what do we do on this peaceful alien planet? Rev up the engines and rattle the machinery. Next off - sound of Perseverance doing a wheelie and handbrake turns. (Robotarm-brake turns?) The locals will be getting seriously pissed off.

    Breaking News!

    Ingenuity just completed its Fifth flight!

    It's now moved to a new 'airfield' and is waiting for Perseverance to catch up.

    Assuming this is successful, it will begin a new life as Perseverance's scout.

      Real question, can the rover pick up the drone to move to another location?

      1. DS999 Silver badge

        It can barely lift itself off the ground in Mars' thin atmosphere, it would be lucky to pick up anything that weighed more than a pebble.

          Re: Breaking News!

          Might want to re-read the question, DS999.

          And the answer to Trigonoceps occipitalis is a simple "no". It's not designed for that, no general purpose grasping tool. Might be able to nudge it back onto it's feet if the wind manages to blow it over, though.

    "Alien world"??? There aren't any aliens on Mars.

    Despite what you may have heard from centuries of fiction, Mars does not have alien life.

    And if there aren't any aliens, it is by definition not an alien world. It's just a hunk of rock with a thin, non-breathable atmosphere.

    1. Throatwarbler Mangrove Silver badge

      In this case, the definition is:

      unlike one's own; strange; not belonging to one

            noun

            - the earth or globe, considered as a planet.

            - (often initial capital letter) a particular division of the earth: the Western world.

            - the earth or a part of it, with its inhabitants, affairs, etc., during a particular period: the ancient world.

            - humankind; the human race; humanity: The world must eliminate war and poverty.

            - the public generally: The whole world knows it.

            - the class of persons devoted to the affairs, interests, or pursuits of this life: The world worships success.

              We don't know what is on the barren lifeless rock, or if indeed it is barren or lifeless - beneath the surface or was in the past.

              Hence the curiosity and perseverance robot probes and all the history making achievements you seem to not care about.

      I'd hate to alienate you, or otherwise show you something alien to your current education, but the term "alien" doesn't mean "little green (grey, whatever) men, nor does it imply the existence of life. What it means in this context is strange or foreign. Both of which Mars is, at least compared to yer mum's basement.

      From the Latin alienus: of or belonging to another, not one's own.

      Despite what you may have heard from centuries of fiction, Mars does not have alien life.

      Well, it's nice of you to let us all know from your position of no doubt vast (but, somehow, anonymous) wisdom. Perhaps it would have been kinder of you to tell NASA that before they spent a few billion dollars sending a rover there to look for signs of life.

    Duty Free on Mars ?

    What is the situation regarding duty free purchases while on Mars? I assume that as there is no tax authority or customs & excise there, that any purchases (such as booze or fags) would be supplied tax free. Although perhaps there might be duties to pay when you brought your purchase back to Earth?
