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 giants cloud tops on Aug. 27, NASAs Juno spacecraft has sent home unprecedented images of the planets north pole, revealing a stormy fluid-scape that looks as if it could be from a totally different planet.
Last weeks flyby was the spacecrafts 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, theres surprisingly little known about its polar regions and so Junos close-up camera work was bound to deliver a few surprises.
As the JunoCam imager revealed, Jupiters 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.

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

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 .

(10,857 posts)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.

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.
