Today is Jupiter Orbit Insertion (JOI) minus 180 days. 53.5 days after JOI, Juno will make its next close pass to Jupiter, and that's when we expect to get the first good images from Junocam, although there may be some imaging during approach and earlier on the first orbit.

Coincidentally I took the attached photo at work the same day this topic was created. JOI used to seem so far off, but now it is just around the corner. Lots of test runs to review plus lots of planning work to go. July 4th will be a very long but fun night!

Even if Juno doesn't take many images during approach, the other instruments will be active to detect entry into the magnetosphere, correct? Any idea when that would happened (I know the magnetic field is gigantic, but not sure exactly how large).

Posted by: ZLD Jan 13 2016, 03:58 AM

Using some rough math, I would say late March on into April there should be some detection of the magnetosphere.

Posted by: elakdawalla Jan 13 2016, 03:58 AM

Juno does plan to take some images during approach. They have to turn off all the science instruments 5 days before JOI.

Posted by: mcaplinger Jan 13 2016, 02:55 PM

Certainly, but at a range of 5.2e6 km on JOI-5d, Jupiter is about 40 pixels across, so they won't be great images. [Junocam, maybe JIRAM does better.]

Handy formula: Junocam Jupiter size in pixels ~ 210/d, d in millions of km

Juno just set a new record for solar power distance, beating out Rosetta's hibernation phase. Very impressive!

BTW, I ran across this technical description of JIRAM -- http://www.ifsi-roma.inaf.it/jiram/downloads/JIRAM%20Tech%20note.pdf -- that has some detail about how the instrument works. Its IFOV is about 2.8 times finer than Junocam's, so at JOI-5d Jupiter should be about 112 pixels across.

I haven't seen any inflight imaging from JIRAM yet. According to http://www.lpi.usra.edu/opag/jul2013/presentations/juno_efb_plans.pdf images were supposed to be taken of the Moon during EFB.

A Google tabular site has been created that displays observations planned by the Juno investigations, together with Earth-based supporting observations: https://www.missionjuno.swri.edu/planned-observations.

This will be regularly updated by the Juno science team and by the supporting observers.

Back from the http://www.ajax.ehu.es/Juno_amateur_workshop/pictures/index.html, I see that the http://www.ajax.ehu.es/Juno_amateur_workshop/talks/index.html of the Europlanet workshop: "Juno Ground-Based Support from Amateurs: Science and Public Impact", are already online.

Most of the sessions have been recorded by video. Providing the recordings online is pending.

(As a personal note: This has been a rare opportunity to find out that people you otherwise know only virtually via web are actually real! It seems, most of the participants shared this experience. Thanks to the orga-nice-rs, who made it possible! )

Entering 'Jupiter space' (by the standard of gravitational influence) https://www.missionjuno.swri.edu/news.
Crossing the magnetosphere should be soon as well, I'm assuming? If the instruments are on they should detect the transition.

Posted by: elakdawalla May 31 2016, 03:09 PM

The instruments should be on; they are all working on approach, but every instrument will be turned off 5 days before JOI until after orbit insertion.

I have a lengthy "what to expect" blog post about Junocam imaging coming soon -- it's currently under review.

Superb in-depth article, thank you so much Emily. Expectations-management of the highest order! Can't wait to see the data trickle in.

Posted by: propguy Jun 24 2016, 08:11 PM

Wow, it is getting really close to JOI (10 days, Woohoo). Next Tuesday we get my prop system all ready for JOI by opening valves to repressurize the propellant tanks. We haven't used that hardware since the DSM's in 2012 (but they will open just fine). The steps to JOI effort is summed up pretty well in a recent article. Go Juno!!

At work sitting on console for JOI. Not allowed to state much detail since ops cannot be the source of any original data (it must be released through channels first), but less 6 hours to burn and all things look great. Go Juno! When they show then Lockheed Martin Mission Support Area (MSA) I will be in the Propulsion station 2nd in line from the main camera.

By the way, there should be a new documentary about Juno on the Science Channel tomorrow at 9 PM Eastern/8 PM Central (6 and 9 PM Pacific). If it didn't end up on the cutting room floor there should be some MSSS material in it.

Finally home. What a night! I could do that again many times (the only more exciting time on console was watching Phoenix land on Mars). It was 5 years ago today I was in Cocoa Beach watching fireworks, prepping for Juno propellant load that week (seems like more than 5 years though). Not able to sleep yet but sitting back drinking a Belgium Tripel I bought in Brugge last year, watching my DVR of today's the Tour de France stage (I love to bike). Jupiter is so bright in the West sky at sunset right now, and now each night I and everyone on Juno can look up and know that we have something at that bright point of light. With Mars also bright to the South at sunset of makes a nice pair of spots in the sky. I worked Cassini many years ago (1st interplanetary mission) and cool to know I worked 2 of the 3 outer planet orbit insertions. How long the 7 year Cassini cruise seemed at launch and now it has been at Saturn for 12 years (I am starting to feel old).

Kudos to Mike Caplinger and all of MSS for that approach movie. It was much more awe inspiring that I had imagined. Really made me feel like we were looking out the (albeit spinning) port hole as we came into port Jupiter. The entire ops teams stopped to watch it when it was played in the press conference. Got to get to sleep now since we get playback data tomorrow. Go Juno!

Great to see Aussie news highlighting the Juno mission.
I guess a minor nitpick, they are saying, Juno has entered Jupiter's
orbit. Should be, has entered orbit around Jupiter. No prob, most
people you speak to are very impressed.

Posted by: mcaplinger Jul 6 2016, 04:40 AM

Thank you. There hasn't been much discussion of how the movie was made. We took highly compressed RGB images once every 15 minutes for 17 days (every 30 minutes on day 1), from 12 June to 29 June, with a few multihour gaps. The decompressed and dark-subtracted images were processed through a pipeline I wrote in Python using the OpenCV toolkit, which finds the planet in each color band, subpixel registers the colors to each other, rotates the image to north up, attempts to mask out the planet and then stretches the background harder so that the moons are visible, and then composites everything together. (No spacecraft attitude telemetry was used because we weren't sure when the C kernels would be available.) Images where the planet was split across filter boundaries had to be fixed manually using a GUI I hacked together. Those frames were then handed off to my colleague Mike Ravine, who laboriously fixed all of the remaining stray light, noise pixels, color misregistration, etc by hand. Those were handed off to JPL for production.

Sorry about the lack of release of the raw data. That decision was made above the pay grade of anybody at MSSS.

Posted by: JohnVV Jul 6 2016, 04:51 AM

the only rotation kernels for july is the 2009 original "nominal"
"juno_sc_nom_110807_171016_v01.bc"
and location kernel
"spk_pre_160413_160913_160613_jm0002.bsp"

Posted by: mcaplinger Jul 6 2016, 05:05 AM

I believe that C kernel production is on a weekly cadence; the most recent, http://naif.jpl.nasa.gov/pub/naif/JUNO/kernels/ck/juno_sc_rec_160619_160625_v01.bc was posted on 29 June and I expect the next set to come out tomorrow. This would have been too late for our processing, so it was the right call. Of course it's not clear that using C kernel information would have been better. Instead we just used OpenCV "blob detection".

Posted by: mcaplinger Aug 9 2016, 11:05 PM

Note that two flavors of our processed approach movie images are at https://www.missionjuno.swri.edu/junocam/processing -- I think what they're calling "level 1" is color-registered but unstretched, and what they're calling "level 2" is rotated, stretched and hand-processed to remove noise and other artifacts from the automatic processing.

Posted by: elakdawalla Aug 10 2016, 12:28 AM

This is awesome -- I'm processing new thumbnails from them right now.

I noticed that frames 1154-1493 from the "level 2" set appear to be offset to the left from all the other frames by 150 pixels.

EDIT: I have now added the "Level 1" and "Level 2" images to my https://planetary.s3.amazonaws.com/data/juno/junocam_approach.html, and have replaced Gerald's thumbnails with ones cropped from the Level 2 data.

Posted by: mcaplinger Aug 10 2016, 04:44 AM

Yes, that seemed to creep in during the manual processing phase and would have to be fixed before someone made a movie just from those frames.
