#2"The download of six megabytes of data collected during the six-hour transit, from above Jupiter’s north pole to below its south pole, took one-and-a-half days."
...surely that's a typo and they mean gigabytes?

Nope, it just takes this long for the data to travel 588 million kilometres [1]. Also the space craft will have a low powered transmitter.

The solar panels that Juno has produce only 500 watts of power. You would need a lot more then that to be sending gigabytes of data in any meaningful timeframe. So yes it really is just six megabytes of data taking 30h+ to download. Btw the panels would produce 14kW at earth orbit but suns power goes down quite fast as you move away from it. Also the farthest from the Sun we've ever used solar panels. Traditionally missions this far from the Sun have used some kind of a nuclear power source (RTGs). Though I don't think they could produce 500 watts without being very big.

#5“Saturn has a hexagon at the north pole,” said Bolton. “There is nothing on Jupiter that anywhere near resembles that. The largest planet in our solar system is truly unique. We have 36 more flybys to study just how unique it really is.”
This is the first I've heard of Saturn's hexagon, very interesting: http://www.space.com/30608-mysterious-saturn-hexagon-explain...

#6Absolutely breathtaking.
Interesting that they phrase the headline almost as if to imply uniqueness. My impression was that Saturn's hexagon was the unique situation (occurring, hypothetically, only under very specific conditions). Is it expected then that Uranus and Neptune's poles will look different still?

Transmission is one thing, but collection is another: did they really only collect 6 megabytes of data over the course of a 6 hour flyby?
Off topic, ish: does anyone know how large a solar panel array would have to be to supply all of our current energy use, if the array orbited the Sun at the same distance Mercury does?

>The largest planet in our solar system is truly unique.
Hold on -- how much do we know about the poles of gas giants in other solar systems? I'm guessing we can't get a good look or anything...
Edit: added quote to clarify what I was responding to.

Why "surely"? One of the main things about the Juno probe is how underpowered its tech is.
