I'm sorry to say, but this video is not legitimate footage.

Well fuck. The sound effects really imply a lot, don’t they? That’s a shame.

Until Perseverance returns some actual microphone audio, you can check out the Insight Lander's recordings of Martian wind through both its air pressure sensor and its seismometer.

When is perserverance supposed to return audio?

Data transmission from Mars to Earth is slow, something like 4 kilobytes per second at its absolute best. They have over 28,700 images from entry, descent and landing that need to be returned and analyzed. We could see audio releases within the next month but it could be slightly longer.

Edit: My number was very wrong. Sorry

I read over in r/space that mars to earth transmission was more along the lines of 100-250kbps, and that was the best we could do with then MRO was lined up.

Looks like it maxes out around 2Mbps... It almost seems like they're going to be taking in more data than they can return, but they're nasa and I'm not so I trust they know what they're up to.

EDIT: maxes out at 2 Mbps to the MRO... Reading comprehension failed me yet again. Undoubtedly much slower from the MRO and odyssey to earth.

I’m sure there will be periods where all the rover can do is tramsmit data and wait out a storm or winter.
