In case anybody was wondering "Why is the frame rate so lousy?" the answer is that the probe only has about 325 bits per second of downlink on average. https:/

- sgt 4y agoWould it be possible to extrapolate frames in between to give one smooth flyover?
- giantrobot 4y agoYes but it will look like there's extrapolated frames. I'm sure you'll see something like that in a YouTube video or something on the Discovery channel but I don't see the point of NASA doing that.
- Cthulhu_ 4y agoAnd are there additional images in the probe's storage that will be transferred over the coming... years?
- shrx 4y agoNitpick: you interpolate data between two known points (frames), and extrapolate beyond the first or last known datapoint.
- sgt 4y agoThanks for the correction
- scrollaway 4y agoYou just blew my mind. Thanks for pointing this out, what seems obvious in hindsight :)
- sgt 4y agoI guess extrapolation is quite simple: just pitch black
- abrichr 4y agoHere's an attempt: https://youtu.be/RgvxLEYeb3g https://youtu.be/RgvxLEYeb3g
- sgt 4y agoReally cool - if you could also change the shape of the planet it would look even better.
- skohan 4y agoWhat's the limiting factor on bandwidth constraints for probes like this? Is it the power of the probe? Is it the distance from earth? I wonder if you could build a mesh network of satellites/probes out farther into the solar system to get better connectivity for projects like this.
- rich_sasha 4y agoThe limiting factor is power/distance^2 basically, which determines the signal/noise ratio, which determines the bandwidth. A mesh network sounds fun, though you'd have to have a fair few probes, as their orbits wouldn't be in sync. Also that far from the sun, solar panela don't cut it and you need nuclear thermal generators, which have a finite lifespan.
- credit_guy 4y agoAlso the power. Juno does not have nuclear power, only solar panels. The Sun is quite dim at Jupiter’s distance. From wikipedia: Power: 14 kW at Earth,435 W at Jupiter Overall the strangth of the signal coming from a solar powered spacecraft in the outer Solar system should go down with the 4th power of the distance.
