This discovery is thanks to Perseverance having microphones. It's crazy to think about that 2021 was the first time we had working microphones on Mars. The first Mars Microphone was originally supposed to land in 1999 on the Polar Lander, but that one didn't survive the landing. The next was in 2008 on Phoenix 's Mars Descent Imager, but in integration testing a bug was discovered that made the Descent Imager risky to use, so that was never activated. And on all the rovers since then a microphone wasn't deemed important enough compared to all the other possible payloads | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||

Does that mean Mars' ground is electrically charged (positively or negatively) or what? | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||

Did I? Sorry, it's a pretty peeve of mine to reject inclusion in some sort collective that I have no awareness of. In my world attribution should be stated clearly, so the title should be the far less catchy 'Research Institute in Astrophysics and Planetology in France detected lightning on Mars'. | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
