2160p also shows up for me on Firefox & Brave. Golden rule: don't use Safari for Youtube.
Is this about VP9 support?
Of course Apple refuses to add VP9; Google demands that Apple would never sue them over any patent. Any. It looks like Google/YouTube caved in, and has/will start encoding (the most recently uploaded) videos in AV1 codec, which will work on tvOS. Hopefully that will translate to Safari on macOS and iOS for those who use it.
Calling it “video” may be technically true, but lees interesting than Google Street View (which is not video, but more interactive).

You're not really paying for the ads, you're really paying for an incredibly crappy music streaming service (Youtube Music).

Earlier this year I made a video[0] where I took two images which are frequently posted on reddit that show the movement of martian sand over a day and interpolated (with python and opencv) the movement into a smooth video. I'm currently working on restoring some Apollo footage, but one of the pending projects is taking the Curiosity descent sequence (at 4 frames per second) and give it a shot at some nice quality, X…

I take a different approach and I can't say I haven't found issues (I have, many, I'm working on them).
My goal is to reach a level where there are almost none artifacts (there are a couple in that video at the start, when the shield is released and when there are many large movements of the camera due to Curiosity dangling off the parachute). As I said, I'm still working on it, and in between my other side projects, work and quarantine I've been on a less-than-ideal situation.
In time, if I pull it off, I'll post it and I guess you'll see it.

The movement shown in this video[0] happened over the span of a martian day. Do not dismiss the winds of Mars, as they have also killed[1] a couple of rovers already. [0] https://youtu.be/k7pfdFMVj-o [1] They have also breathed new life on one of those (before killing it, yes) by cleaning the solar panels. I'm referring to the MER Rovers Spirit & Opportunity.
As you said, that movement of was over a day and the camera was pointing downwards towards very tiny details of fine grained powder next to a wheel. You wouldn't notice anything in real time video. The problem with Mars dust is that it's electrostatic and sticks to surfaces like solar panels. https://www.nasa.gov/feature/goddard/the-fact-and-fiction-of... >It is unlikely that even these dust storms could strand an as…

"There is a beautiful selfie at timestamp 6:41" Where's the camera in that selfie? Perhaps edited out of the mosiac?
There's an explanation and video[1]; I remember thinking the same a few years ago. [1] https://www.nasa.gov/feature/jpl/nasas-curiosity-mars-rover-...
That's probably a great example of one of the benefits of these rovers running for so long. They'd never have scheduled something so non-science-oriented if they only got the few weeks they expected, but when your mission exceeds expectations by several thousand percent, you have time for such things.

I believe the images are quite aggressively recolored and cleaned up. The narrator states that the original images would be reddish and hazy.
The cameras on the rovers are not the same as the camera on your phone or a DSLR. Each camera has specific sensors for different wavelengths of light [0]. The images are really just the wavelength reflection intensity measurements (think of it like RAW images on a DSLR but for more than just RGB). The colorization is done by taking several of these images for wavelengths and adding them together. For example blue is…
But you are right that many times scientific missions will have monochrome CCDs with a filter wheel on top (Cassini, Galileo, Rosetta, Dawn to name a few).
