Detection of triboelectric discharges during dust events on Mars

Yes, and don't forget that you need to modify & certify it to work in 1% of Earth atmospheric pressure and down to -75C, and get it integrated into flight software running on a RAD750.

This doesn't require anything fancy. I haven't used my sound engineering qualification in 14 years and I could do it by hand. You can visually scan through the recorded waveform and look for shapes that stand out. Simple audio processing techniques like using a noise gate to shut off the volume whenever the input level is below some configured threshold can make this even easier.

Listening to hours of recording doesn't even seem like a lot considering this is the only microphone we have on another planet. You would need like 4 people doing this full time, which is a drop in the bucket for a project on this scale.

Of course this is not how it's done and almost all of the recording will just be wind or noise from the rover itself, which can easily be filtered out.

If you have enough RAM, start with a ring buffer.

On interesting event: compress and transfer the relevant chunk of audio from the ring buffer back to Earth.

Interesting event trigger ideas:

1) loud sound after quiet time

2) manual timestamp request from control

3) video clip recording

4) midnight, sunrise, noon, sunset. These are mostly so you have some daily baseline.

5) science package running

6) rover moving

7) abrupt camera change

Well, there are these things called computers, and they’re really very good at this stuff. It’s not exactly rocket science (heh) to write a program to listen to an audio stream and mark and log every occurence of something else than background noise and ambient wind sounds (if Martian winds are even loud enough to make sound). Everything else that the rover has to do automatically is way more complicated.

It’s pretty likely that the entire stream of silence isn’t being stored, or sent to Earth, only the interesting parts. There isn’t any way for people to listen in real time anyway, because communications (can) only happen at specific times of the day. Every interplanetary mission works by sending a preplanned sequence of commands one day, then coming back the next day to see what the probe/rover/whatever sent back, then planning the next set of commands, and so on.

Lightning is static electricity that builds in an atmosphere.

I assume it is essentially more about if it includes the author of the article. In the specific case, the author is a journalist not a scientist part of the actual group that did the work, so their "we" seems to forcingly include everybody in the planet, thus also OP here. I dont think OP would have an issue if one of the scientists in this case used "we".

It's specially annoying when people use it to latch on to achievements they had no part in. Like Americans today going "We stopped Hitler" etc.

The journalist writing the article starts with

> Scientists analyzed 28 hours of recordings over two Martian years, listening for electrical signals.

Not with

> We analyzed 28 hours of recordings over two Martian years, listening for electrical signals.

Nor

> Humanity analyzed 28 hours of recordings over two Martian years, listening for electrical signals.

Somehow it would be weird to assume that "everybody" put the effort into this, but "we" all reap the success.

On the other hand, this is done with taxpayer money, and even if not, it is done in the context of the whole global economy and we are all interconnected and everybody steps on the shoulders of giants anyway, so, in the grand scale of things, a use of "we" can make sense for everything that happens.

Moreover, OP's argument holds also for the france case anyway.

I did not think much of the title before reading the parent comment as I also read "humanity", but now it's the lack of consistency and double standards that annoy me. "France detected Lightning on Mars", fine, let's stop cutting the funding of public research so we can keep on saying we. Also let's title "We released GPT-5", "We landed a rocket on a barge".

> Whenever it's a space topic

It relates "us" to "earthlings". We, as in "humans", live on Earth. Space is "outside". We humans look outside to space and discover things there.

I feel it's more that sense of making clear that it's "us", humans, doing the discovery vs some other species or entity out there.

Imho it's a quirk due to English's hate for the passive voice. Most languages would just go with "Lightning was detected on Mars". Naming the institute does not add any value to the average reader here, nor does the word "Scientists". "France" adds a bit of value, so that'd be the next best thing after the passive voice
