Cool! I wonder why balloons have not been used much on other planets? Is it the weight of the gas? The USSR had the the Vega 1 and 2 balloons on Venus, but presumably further missions could be pretty useful for studying planetary atmospheres, even for gas giants.

I don't think it's viable for Mars; the atmosphere there is only 1% of what the Earth's is, so (amateur armchair maths) to carry the same payload they'd need a balloon 100x as large, plus something to fill it with lighter than the surrounding atmosphere.

Funny how there seems to be neither dust on landing or take-off.

Earlier quoted context omitted.

Wouldn't transcoding the video still produce the same amount of heat?

Not that much as it will no doubt be hardware accelerated.

Roughly the start of success from the livestream: https://youtu.be/p1KolyCqICI?t=2265 Video (of the video from Perseverance): https://twitter.com/NASA/status/1384099167832735748 (Better version from the livestream in child comment https://news.ycombinator.com/item?id=26861334 )

I hope that in a little while we get an actual video like we got when the whole thing was descending onto the ground. I am not expecting much from Ingenuity but I would be very disappointed if we didn’t see any video from Perseverance. I know doing video requires a lot of power, but I really feel it is justified for something like this. It would become a historic video.
