Juno reveals that Jupiter's north pole is 'like nothing we have seen or imagined'

Source: LA Times

Seen from a different angle, Jupiter looks like a whole new world.

After flying within about 2,500 miles of the gas giant’s cloud tops on Aug. 27, NASA’s Juno spacecraft has sent home unprecedented images of the planet’s north pole, revealing a stormy fluid-scape that looks as if it could be from a totally different planet.

Last week’s flyby was the spacecraft’s first such pass with all its science instruments turned on, as well as the closest of the 36 orbital flybys that the spacecraft is set to make during its mission. While Jupiter is the largest planet in the solar system by far, there’s surprisingly little known about its polar regions — and so Juno’s close-up camera work was bound to deliver a few surprises.

As the JunoCam imager revealed, Jupiter’s north pole is bluer than better-known areas of the planet, which are often dominated by red-brown hues. Gone are those iconic bands of light and dark; in their place, a whole lot of storms.

Seems reasonable. Data at that distance is pretty slow FrodosPet Sep 2016 #5

I'd have to believe it's 6GB of data. 6mb seesm rather tiny for this collection of data.

Limited power plus loooooonnnnnggggg distance - You definitely cannot run broadband that far.

I wonder if they can even compress the data or if they send it raw in case of what seems like inevitable data errors.

.... and reliably transmit it, although I don't know if they do in this case.

FYI: the first transmission of the now famous Pluto picture showing the "heart shaped feature was JPEG compressed - although it was subsequently down linked with lossless compression .

Not only is it extremely difficult to accurately transmit data at any speed over that distance, the JunoCam is a public relations instrument that the scientists are frankly a little hacked off about--they were effectively compelled to put the camera on by Congress.

The camera is limited to a maximum of 40 mb of uncompressed pictures per orbital pass, which is probably not more than two percent of the total amount of data that can be sent in one 53-day orbit. Project managers expect (read: hope) that the camera will be killed by Jupiter's radiation within the first six or seven close orbital passes.

"The instrument will be used for education and public outreach and scientific studies conducted by students."

Education, student envolvement, and public outreach are very important components of our space programs. It is very important that the public be involved and engaged in our scientific endeavors and especially our up and coming scientists and engeneers. Frankly, any scientist that fails to support public outreach or providing substantive oportunities for tomorrow's scientists and engineers doesn't understand the foundations that the institution of science is built upon.
