Juno spooks NASA, sends back wild images from Jupiter
Updated 6:06 pm, Wednesday, March 1, 2017
The Junocam is a color-imaging eye pointed at the Jovian planet. Its gaze is be mostly directed by the public via a public-voting platform. The camera then takes raw images of areas both directed by the public and scientists. Once the images are uploaded, citizens with little to read or watch or otherwise distract themselves with other than news about the new U.S. president are invited to modify the images and upload them to the NASA website. Here are some to enjoy.
Citizen image (NASA caption): NASA’s Juno spacecraft skimmed the upper wisps of Jupiter’s atmosphere when JunoCam snapped this image on Feb. 2 at 5:13 a.m. PT (8:13 a.m. ET), from an altitude of about 9,000 miles (14,500 kilometers) above the giant planet’s swirling cloudtops. Streams of clouds spin off a rotating oval-shaped cloud system in the Jovian southern hemisphere. Citizen scientist Roman Tkachenko reconstructed the color and cropped the image to draw viewers’ eyes to the storm and the turbulence around it.

From this unique vantage point we see the terminator (where day meets night) cutting across the Jovian south polar region’s restless, marbled atmosphere with the south pole itself approximately in the center of that border.

Risk averse NASA has decided to keep its spacecraft Juno on the looonnnggg orbit of Jupiter.
Earlier in February, the agency said it didn't want to risk firing the spacecraft's engines and bring it in for a closer zip around the mega-planet because of a slight glitch in two helium check valves. I know!
Yeah, NASA. Apparently the valves opened later than expected during a system charge and since they are "part of the plumbing for the spacecraft's main engine" ... well, better safe than sorry.
Faced with a new POTUS and some subtle give and take in the nation over the man and his executive orders, the agency was quick to point out the silver lining of the situation:
Juno's larger 53-day orbit allows for "bonus science" that wasn't part of the original mission design. Juno will further explore the far reaches of the Jovian magnetosphere – the region of space dominated by Jupiter's magnetic field – including the far magnetotail, the southern magnetosphere, and the magnetospheric boundary region called the magnetopause. Understanding magnetospheres and how they interact with the solar wind are key science goals of NASA's Heliophysics Science Division.
"Another key advantage of the longer orbit is that Juno will spend less time within the strong radiation belts on each orbit," said Scott Bolton, Juno principal investigator from Southwest Research Institute in San Antonio. "This is significant because radiation has been the main life-limiting factor for Juno."
Meanwhile, one unique feature of the human-made object zooming around the largest planet in our solar system, of which nearly no conspiracy theories of alien life or government coverups exist (even fevered brains know it's too chaotic of a place for such things, though its moons are another thing all together ... ) is the Junocam.
After launching back in 2011, NASA's Juno spacecraft arrived at it's destination last June. Set on a course for Jupiter, the craft took years to reach the gas giant, but June is in the planet's orbit and taking stunning images. One of the latest released by NASA depicts the planet's swirling and stormy atmosphere. The close-up image captures streams of clouds spinning off a rotating cloud system shaped like an oval. The storm is in Jupiter's southern hemisphere.

In the gallery above, you can see images that NASA has produced from the camera, which are presumably representative of how the planet would look if you were floating just above it in the cold vacuum of space while being cooked by radiation.** And, just after those, you can see some of the images citizens have made of that rarest of vantage points.
* "Since the mission's beginnings, Junocam was intended almost entirely as a public outreach tool, in contrast to the spacecraft's other instruments that will address Juno's core science questions. Juno scientists will ensure Junocam returns a few great shots of Jupiter's polar regions, but the overwhelming majority of the camera's image targets will be chosen by the public, with the data being processed by them as well," NASA said.
** "Scientists believe that the combination of this metallic hydrogen along with Jupiter's fast rotation -- one day on Jupiter is only 10 hours long -- generates a powerful magnetic field that surrounds the planet with electrons, protons and ions traveling at nearly the speed of light. The endgame for any spacecraft that enters this doughnut-shaped field of high-energy particles is an encounter with the harshest radiation environment in the solar system," NASA wrote.
