The narrator explains why getting HD video would be impractical, but I disagree that we get the same experience from panning stills. imagine seeing the swirling dust, shifting sands, the bumps and parallax from a moving rover. that would be so cool!

Parallax, maybe, but no wind = no swirling dust or shifting sands, no?

But there is wind, and storms.

A lot of people bashing on this, but I think overall it's pretty impressive just showcasing to more people what Mars looks like. I for one was impressed and enjoyed the panoramic effect.

Crazy to think Earth might eventually look like Mars.

Would be great to add a quality binaural microphone and listen to the sound of Mars.

Apparently the Mars 2020 Rover (https://mars.nasa.gov/mars2020/spacecraft/rover/microphones) will have that capacity when it lands in February 2021 but the microphones may break after landing: "Engineers are optimizing this microphone for space from easily available, store-bought hardware. It is unlikely it will work beyond landing. If it does survive, we may be able to hear the sounds of the Martian winds and sounds of the working rover, such as the wheels turning, or the motors that turn its head, and the heat pumps that keep it warm."

There is in fact wind. Only ~1% as much air as Earth, but it's sufficient to support phenomena like dust devils.

Of course, it's very weak, so it couldn't push over a spacecraft or building like in "The Martian", but I suspect sands shifts on a very slow timescale. I'm not sure.

This is a really cool video and I don't mean to detract from it, but seeing how its 10 minutes and 8 seconds long annoyed me so much (and not for the reason you think). "10 minutes" is an ad milestone for videos on youtube. I systematically click away and hide videos that are between 10:00 and 10:20 minutes long: They'll almost certainly have been artificially slowed down to match the ad requirements. It's infuriatin…

YouTube just changed the ad milestone to 8 minutes, and this was posted after this change.

On the same topic, who determines the '10 minute' and '8 minute' time scale perfect for engagement and how did they end up with these numbers?

10 minutes is the the milestone for "mid-roll" ads. As far as I can tell, this video has no ads in the middle.

It's the minimum length of time a video must be in order to enable mid-roll ads.

The 10 minutes one seems pretty arbitrary, but to arrive at 8 mins I suspect that Google studies how much time there needs to be so that mid-roll ads don't negatively affect engagement.

(Shout-out to all the wonderful, brilliant engineers working on figuring out how to minimize the user's reaction to cramming AS MANY ADS as possible down their brain)
