The physics of orbiting bodies is about to take away our communication with Mars for a couple weeks.
The atmosphere of Mars is thin, but it still transfers sound.

See https://mars.nasa.gov/resources/25790/perseverances-selfie-with-ingenuity/ for info on how the image was taken.
Stop a moment and look at this image. The human eye loves a vanishing point image and this is a good one. Look at the way the tracks interact with features of the surface. Look at the other set of tracks to the right. Perseverance has been busy looking for just the right spot. Finally, look at Ingenuity, newly set on the surface of its new home, waiting for its chance to rise up and explore on its own.
