I had been wondering why no new information had been coming from spacecraft Juno. The reasons are now clear.

Juno went into safe mode Oct 18. Information from the next pass of Jupiter was lost. The trouble has been identified as a sticky check via in the main thruster system. (much less trouble than Galileo had). This makes orbit change iffy, so Juno is staying in it’s long period 53 day orbit for now. The smaller thrusters use for changing the spacecraft orientation and stabilising the orbit are still in perfect condition.

Junocam has been off since Oct 18 and will be switched on again at perijove at Dec 11.

The only way you could get me to watch it would be sever my spinal chord and point my eyes in that direction.

I was just trying to help out… you’re the one that wanted to know..

Thanks for the correction.
Cee sharp diminished?

Still don’t see any new news from the Dec 11 Juno flyby of Jupiter.

“ On Sunday, December 11, at 9:04 a.m. PST (12:04 p.m. EST, 17:04 UTC) NASA’s Juno spacecraft will make its third science flyby of Jupiter.”

“The spacecraft team continues to weigh its options regarding modifications of Juno’s orbital period—how long it takes for the spacecraft to complete one orbit around Jupiter. At present, Juno’s orbital period is 53.4 days. There had been plans to perform a period adjustment maneuver with the spacecraft’s main engine on Oct. 19 to reduce the orbital period to 14 days. The team made the decision to forgo the maneuver in order to further study the performance of a set of valves that are part of the spacecraft’s fuel pressurization system. The period reduction maneuver was the final scheduled burn of Juno’s main engine.”

“This will be the first time we are planning to operate the full Juno capability to investigate Jupiter’s interior structure via its gravity field. The auroral mapper will not be on during the encounter.”

Juno flyby of Jupiter successful.

https://www.nasa.gov/feature/jpl/nasa-juno-mission-prepares-for-december-11-jupiter-flyby

NASA’s Juno mission completed a close flyby of Jupiter on Sunday, Dec. 11, its latest science orbit of the mission. Seven instruments and the spacecraft’s JunoCam were operating during the flyby to collect data that is now being returned to Earth. Juno is currently in a 53-day orbit, and its next close flyby of Jupiter will occur on Feb. 2, 2017.

No new images yet, I think.

still a great movie

I remember when the first high resolution pictures were published from Galileo … blew my mind.

Latest raw images from Juno are available, but not particularly interesting. Eg.
