The ESA probe lands next December I believe ?

If by land you mean 'scream into the surface at 15,000MPH'*, then it's been delayed because they couldn't sort the parachutes out in time for this launch window. It should arrive in 2023.

*Hopefully it will safely land, but NASA are the masters of Mars!

If a tree falls in a forest, does it make a sound?

No, it vibrates the air, it needs an ear to covert those vibrations to sound and a brain to comprehend them.

What is an ear? Is it a seismograph? Is it a microphone? Is it a speaker? Is it a human ear? Is anything real?

I believe the frequencies recorded by the seismometer had to be sped up and increased in magnitude to create a sound that the human ear can even register.

Nah, they just tweaked the frequencies of the sound waves a bit, because they're dominated by low frequencies, but still within the hearing range. Even the recent ones are tweaked and processed. :emoticon-0105-wink:

Frequency modulation - extreme?

I'm fairly sure that a seismometer won't produce a recording that a human can hear, unlike the microphones on Perseverance, but feel free to find some information that proves otherwise.

The parachutes have been tested and passed at the NASA facility so it sounds good at the minute.

All I said was that they'd recorded sounds. It's stretching things to then try to add the human bit, given that the distance dictates that all noise on there is inaudible to humans, as we're all quite a way from it. It also depends on how you are describing 'audible' as some 'sounds' are also sensed in other parts of the body.

Top and bottom, the earlier recordings are sound, and the current ones are processed. Arguments around that are pretty pointless really though.

Alright, put it this way, the seismometer on InSight can detect the tidal forces from Phobos. Can you hear our moon, which is considerably more massive? The sounds recorded by Perseverance are as they would be if a human were present on the surface.

None of which changes anything I put. :emoticon-0105-wink:

Is there an actual debate going on here ? If there is, it would help if either you or Des Head or .... could articulate what the debate is trying to establish. Exactly what is the question?

I think it's the existence of noise and whether its audible .

I think it's the beginning of another conspiracy theory.

Did they really land a spacecraft on Mars? Or was it just a film crew in the Nevada desert?

tbh Top and Bottom of it , NASA said that the recording from perseverance are the first ever audio recording from another planet , they produced both so I will go on their definition of Audio recording rather than try to argue about what was processed with what and when and just enjoy history as its happening in front of us

Nasa also described the 2018 recording as the first sounds from Mars. :emoticon-0105-wink:

They're both incredible achievements, no matter what the pedantics.

I know it hertz but this is happening with increased frequency, without a sound argument or anything else to pitch, perhaps you should wave this one goodbye and remain mute.

Mic drop.

Cheers Mic, your words will resonate with some who may be on the same wavelength. DMD applies Bow tie correction*. :emoticon-0105-wink:

*I doubt many will get that.

If seismometers count as the first sounds, then the Viking 2 lander in 1976 wins that particular battle.
