what impressed me more about this video is how earth like an alien world looks like. it may not have vegetation but there's nothing I wouldn't expect to see somewhere on earth.

#63If the rover can stream to the orbiter at 2mb/s, would it be possible stream video to the orbiter and have it save in its buffer? Then it'd transfer to Earth later on?

#64This 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…
Why don't you use Brave browser to get away with those ad?

#65They achieved their goal of monetizing public domain images and getting it promoted on a social network.
Not to mention spreading science wider through promotion is a valuable service to society. Not everyone browses nasa.gov sites. Nor does raw content always hit frontpage of HN.

#66In my youtube quality menu, it only goes up to 1080p. Is this really 4K?
In 9/10 cases you don't see the difference anyway unless you are actually on a very large screen and you don't mind wasting the extra computing power.
But given how aggressively YouTube compresses videos, watching in 4K can provide a huge improvement over 1080p even if your screen only has, say, 1,600 lines like my MBP does, instead of the 2,160 lines that 4K actually produces. It's really about the clarity of textures and how lifelike they are -- it's very noticeable. Of course, this also assumes you have good vision.
I also don't think anyone's too worried about "wasting computing power" here for a short video.

#67Earlier quoted context omitted.
Does this video make them more accessible? It seems to make them less accessible. It's a video composed of readily-available images from https://mars.nasa.gov/msl/multimedia/images
At least they're panning at 60fps, decreasing tearing/seizures

#70Interesting facts that I didn't know before seeing this video: - The opportunity rover captured a barren scene which was named Rub Al Khali (Yes! On Mars!), named after the Rub Al Khali desert area which touches UAE, Saudi, Oman and Yemen. (1) (2) - The video says that Mars rovers send back images (not videos) and then those images are stitched together to create videos, because "nothing ever moves on Mars". But I wo…
Here's a dust devil https://www.youtube.com/watch?v=k8lfJ0c7WQ8 (again, it's still images to make a video) but not because "nothing ever moves on Mars"!
Mars is constantly shifting and changing with its weather and seasons. Ice caps freeze more, and ice caps melt more, water or other liquid flows down hills when it gets warm.
More often than dust storms, a new robot comes down to land on Mars in firey rocket-landing-fueled or bouncing-ball style. Movement.
Mars is constantly hit by rocks from space that create craters and push dust up into the atmosphere.
I've never heard someone say "Nothing ever moves on Mars" because it's really not true and a total lack of imagination. Maybe people think nothing moves because we haven't sent video cameras yet? But...Mars is constantly in motion.
