On the day Ingenuity Helicopter made its 5th and first one way flight to its new base NASA have released audio and video from the helicopter's 4th flight making this the first sound recorded of an aerial vehicle on another world.

During Ingenuity’s fourth flight, a microphone included with the SuperCam instrument aboard Perseverance captured the humming sound of the blades and the din of wind.

The audio is recorded in mono. Scientists made it easier to hear by isolating the 84 hertz helicopter blade sound, reducing the frequencies below 80 hertz and above 90 hertz, and increasing the volume of the remaining signal. Some frequencies were clipped to bring out the helicopter’s hum, which is loudest when the helicopter passes through the field of view of the camera.



Kinda sounds like a UFO too.
Perfect !

You head ( had) to remind me of Bowie! - God I miss him live

Great thread

Only saw him once but it was a special experience.
I'm sure he would love this.

It's 2021. You'd think they've invent better microphones by now.

*sorry to all the 'better camera' folk... but you know...*

It's a science microphone , it's also the first microphone we've sent that actually works so I'm happy for that.

For sure it was special, saw him twice 1978 and I cant remember the 2nd date. Both in Perth.

Hope he made it to Sirius - creepiest video he's ever made, but beautiful at the same time

Powered, controlled, flight, on another world, not that much longer than 100 years after we achieved the same on our own.

That's quite the feat of engineering.

That’s quite impressive.

After the catastrophic start to getting rovers on Mars, we’re smashing it out of the park now

Really cool !

Because the rotors spin crazy fast,I totally expected the sound to be much higher pitched-kind of like a mosquito rather than the low hum.Would it sound the same on earth I wonder?

Once they suss it all out,I hope they will send a whole fleet of drones to explore some of the deep canyons of Mars.
I bet there is some amazing geology down in the canyons,and hopefully a giant fossilised bone or two.
Good place for a future base as well maybe.

Ingenuity is working great in the New Mexico desert on Mars. Awesome sauce.

Won't be long before they need a salty rotary-wing crew chief on Mars.

Sign me up.

I know man, it was tongue in cheek. I've been watching this as close as I can for what it really means for us. And I hope the day comes I can hear a voice from there, one of ours. That will not be one small step, for sure!!

It could be their plans are even more exciting than that.


kicking off a new demo phase where we test this new tech and see how it can aid future missions on Mars and other worlds.

The only "other world" I can think of with an atmosphere suitable for a helicopter to fly is Venus ... how cool would that be !

For colonisation purposes the upper portions of the Venusian atmosphere may offer far more viable conditions where us humans are concerned than Mars does given the lack of magnetic field/dead core, somewhat extreme radiation exposure, and chromium laced top soil that awaits us on the ground.

It would be cool indeed to see a helicopter fly on Venus, need to be somewhat more of a robust affair than its Martian counterpart all the same with surface temperatures about 470 degrees if its going anywhere near ground level.

Not that im telling you anything you don't know or has already been proposed.

am I missing somethin 698deg K?
wiki


about 698 K
1 gridded map. The global average nightside surface temperature of Venus is about 698 K with a spatial variation of over 230 K. Due to very thick and reflective atmosphere7,8,9,10, Venus surface absorbs about 2.5% of incident solar flux as compared to about 50% on

I think given the density of the Venusian atmosphere perhaps a helicopter could operate in the upper atmosphere where conditions are more temperate and perhaps lower itself to a point where it could return images of the surface in relative safety , while it's there it could also take samples for evidence of life in the atmosphere.

As long as there is atmosphere to accommodate the aerodynamics, lift, drag, and the like, and the drone can withstand the conditions, pressure, and temperature, you can fly one on Venus same as here on Earth or Mars for that matter.

Having anything operating on Venus would be extremely difficult.
450*c ....wow. And solar probably is not feasible.

That and the air pressure is tremendous.
A chopper would need much smaller blades though...lol

As with here on Earth the higher you go the cooler and less dense the atmosphere is , not an expert but I assume the density of the Venusian atmosphere would help the helicopter keep aloft.

Seems the Russians have already thought about it and could attempt to deploy drones to the atmosphere of Venus before the end of the decade.

Space agency Roscosmos is planning to launch the Venera-D mission towards the end of this decade, which would mark the first landing on the planet since the Soviet era.

The Moscow Aviation Institute says one option to carry out the planned surface and atmospheric studies is to use drones to obtain data on cloud layers at different altitudes or explore specific areas of surface interest.

Two senior academics, Viktor Vorontsov and Mikhail Yatsenko, presented the proposal during the 45th Korolev Readings event which specialises in space exploration.

The presentation outlined the prospects for developing a 15kg multi-rotor vertical take-off aircraft capable of lifting 60% of its weight as a payload, but with dimensions small enough to fit into the Venera spacecraft.
