Pass 5 completed without malfunctions. Not that many more left now.

We knew Jupiter was weird. Now we're finding out HOW weird.

Juno did an especially close flyby of Jupiter's great red spot on July 11th.



And that's just the optical instruments. I wonder what all the rest saw!

From the article Kyuss posted:
Quote:
Or maybe. Maybe not. The result scientists found after that first orbit is that Jupiter may have a core, but it’s ... fuzzy. Dilute. It may be bigger than first thought, too, containing 7-25 times the mass of Earth (Jupiter’s total mass is 318 times Earth’s). I had to laugh when I read that; I can imagine groups of scientists on either side of this issue arguing for years over whether Jupiter has a core or not, and then finding out that, in a way, they may both be right.
Hydrogen is an invasive gas which forces its way into crystalline materials and makes them brittle.

Juno has completed pass 10/14. After 14 they'll review how well its still functioning and hopefully apply for a mission extension. NASA wanted 36 passes originally before they decided to not risk activating its engine and take things slower. So far so good, anyway, the "titanium bucket" is shielding the computers well and the instruments are holding up. We haven't seen defects on junocam yet, which surprises me. Most important will be the solar panels though. They're its only power source, and must be getting cooked the worst. If those go bad, they'll have to command the engines and dump while they still can.

Juno reveals, Big Red Spot extends hundreds of km below the clouds:


Juno has also detected a new and unusual radiation zone:


The zone includes energetic hydrogen, oxygen and sulfur ions moving at almost light speed. "The closer you get to Jupiter, the weirder it gets," said Heidi Becker, Juno's radiation monitoring investigation lead at JPL. "We knew the radiation would probably surprise us, but we didn't think we'd find a new radiation zone that close to the planet. We only found it because Juno's unique orbit around Jupiter allows it to get really close to the cloud tops during science collection flybys, and we literally flew through it." The new zone was identified by the Jupiter Energetic Particle Detector Instrument (JEDI) investigation. The particles are believed to be derived from energetic neutral atoms (fast-moving ions with no electric charge) created in the gas around the Jupiter moons Io and Europa. The neutral atoms then become ions as their electrons are stripped away by interaction with the upper atmosphere of Jupiter. Juno also found signatures of a high-energy heavy ion population within the inner edges of Jupiter's relativistic electron radiation belt -- a region dominated by electrons moving close to the speed of light. The signatures are observed during Juno's high-latitude encounters with the electron belt, in regions never explored by prior spacecraft. The origin and exact species of these particles is not yet understood. Juno's Stellar Reference Unit (SRU-1) star camera detects the signatures of this population as extremely high noise signatures in images collected by the mission's radiation monitoring investigation.

...intricate cloud patterns in the northern hemisphere of Jupiter in this new view taken by NASA's Juno spacecraft.

The color-enhanced image was taken on April 1, 2018 at 2:32 a.m. PST (5:32 a.m. EST), as Juno performed its twelfth close flyby of Jupiter. At the time the image was taken, the spacecraft was about 7,659 miles (12,326 kilometers) from the tops of the clouds of the planet at a northern latitude of 50.2 degrees.

I almost keep forgetting about Juno because I'm so used to flyby or crash into missions.
So I looked up it's end date and July is as far out as they have officially planned but it will still be orbiting for longer.
It's the little Jupiter orbiter that could!
