Well, the camera itself isn't exactly new. But the Juno orbiter containing it just arrived at Jupiter earlier today (US EDT) after a nearly five-year journey. The camera is called JunoCam and was desgined specifically to create visible-spectrum color photos for the general public to download & process. Folks will even have a say in which features of Jupiter's atmosphere JunoCam focuses on.
Juno is in a highly elliptical orbit, allowing it to get very close to Jupiter for brief periods without being fried by the planet's magnetic & radiation fields. We should see detailed JunoCam pics starting late next month or in early September, after the orbiter's first science pass near the planet.

Cool stuff, I gotta say. I watched the orbital insertion last night on NASA TV.
Juno's real intent, however, is to see beneath the clouds. Something I don't think the ParticipantCam can do.
America just keeps giving us these summer blockbusters. Last year, Pluto. A couple of years ago (also on the Fourth of July) Curiosity's Mars landing. Now, this.

Yup, that's correct. JunoCam is a response to public interest and is also intended to encourage more of it. Juno's main purpose, though, is to gather info about Jupiter's atmosphere so we can better understand what's going on there. For example, is the Great Red Spot largely an upper atmospheric phenomenon or does it extend deep? If the latter, how deep? What elements & compounds is the GRS made of? What's happening at the planet's poles? That kind of stuff.
Right now Saturn, Mars & Jupiter are all easily visible at night in the southeast to southwest sky. We've also got cameras on spacecraft orbiting all three. Definitely cool. :D
-Dave-
-
The first cool Juno imagery is coming in. I've attached a photo, by JunoCam, of Jupiter's north pole. The Cassini orbiter took some similar pics years ago during its slingshot flyby en route to Saturn, but this one is looking straight down at the pole. Nifty! Lots more to come. 8)
-Dave-

Mind boggling :)
-
And gorgeous.
-
What a time we live in. On the one hand there's amazing science and discovery and on the other Trump. ;D

Here's a JunoCam pic of what NASA is calling the "Little Red Spot" (not much red to be seen, but it is apparently a Red Spot-like formation), taken February 2nd during one of Juno's close approaches to Jupiter.

I think I see a UHD 4K box in my future.

A video clip created from some of the latest Juno image data:
https://youtu.be/7hoGy2UFgh4
The contrast here is jacked up a bit much for my taste, but the data is available for anyone to process per their own taste. Not a hospitable planet (unless you're a radiation-eating microbe who digs high velocity atmospheric turbulence)!
-Dave-
-
BTW the main target of Juno's next orbital flyby, in early July, is the Great Red Spot. Let's see what this thing looks like at close range! (And what it's composed of in detail, how deep it goes, etc.)

Amazing photos and information, Dave!! Thanks for your posts.

Incredible imagery. I think Jupiter is moving up abreast of Saturn as the most beautiful planet in the solar system.
-
The first JunoCam pics of Jupiter's Great Red Spot are up for download:

Here's the "North North Little Red Spot 1" from the most recent flyby. It's an anticyclone dating back to at least the early 1990s. The pic is "upside down": north at the bottom.

Here's a corker from the latest Juno flyby a few days ago. Includes a storm (in the image's brightest area) the Juno folks are calling Hurricane Rachel. If I find a direct image link I'll put it here.

Juno completed its 8th observing close encounter with Jupiter on October 24. It’s taking time to get the flyby data, including JunoCam pics, from the spacecraft ‘cuz for awhile the Sun was in the way. :) Should be a pic or two to post pretty soon.

Here’s a nifty pic from the October 24th flyby. It’s big so I’ve provided a direct link (http://dgpa5yltyhwbz.cloudfront.net/Vault/VaultDownload?ID=12617&ts=1510261443) rather than insert it.

NASA has released a summary of data Juno has collected so far on Jupiter's Great Red Spot.
https://solarsystem.nasa.gov/news/2017/12/11
The *GRS extends down more than 300km (200 miles) into the planet's atmosphere!
Also, you'll find a bunch of cool Jupiter images here: https://solarsystem.nasa.gov/news/2017/12/04/10-things-dec-4-awe-inspiring-jupiter-images-not-to-be-missed
-Dave-
*Originally typed GRB and didn't catch the mistake 'til just now. GRB stands for Gamma Ray Burst, a somewhat more energetic thing than the Great Red Spot. :D
-
Dave,
thanks for keeping track of NASA imaging updates and posting them here. I love seeing them.
Brad
-
You're welcome, Brad.
There are a bunch of very cool thermal images of both Jupiter and its geologically active moon Io being shown and discussed today at the fall meeting of the American Geophysical Union. The images come from Juno's Jovian Infrared Auroral Mapper (JIRAM). Hopefully they'll get publicly released soon so I can link to 'em here.
-Dave-
-
Seàn Doran, one of the folks most active in processing JunoCam images, has posted the attached three today via Twitter. Thought I'd just grab 'em and repost here as they're "not bad."
-Dave-
-
Stupefying, as usual. Thanks!
-
BTW, Juno made its latest flyby yesterday evening (US time). Dunno if JunoCam was even active for this one as it was an "orientation pass," used for precisely measuring the spacecraft's position & trajectory relative to Jupiter with (I surmise) the aim of tweaking its orbit if necessary or desired.
-Dave-
-
JunoCam was in fact operating during the latest flyby ("Perijove" #10). Another of the active JunoCam data processors, Kevin Gill, has tweeted these three just-transmitted images. I like that they're less worked than typical, more like what we'd see if we were there ourselves.
-Dave-
-
Dave what's the highest pixel dimension version of these images that's publicly available? I'd like to try a big print of one of these. A gallery wrap canvas.
Thanks!
Peter
-
Peter, have a look here: https://www.missionjuno.swri.edu/junocam/processing
JunoCam images are put together from 1600x155 pixel strips and can be a variety of different composited sizes.
-Dave-
-
Thanks, Dave. Quite the process that camera goes through.
-
One more from the latest flyby, processed by Gerald Eichstädt. These folks have refined and automated their workflows very nicely.
-Dave-
-
Awesome stuff (in the true sense of the word). Thanks for sharing!
-
Here's another pic from the latest flyby, processsed by Gerald Eichstädt. This is looking toward Jupiter's south pole (in shadow) from below.
-Dave-

This one's OT but it's so pretty I had to post it here. It's a recent UV-spectrum photo of Venus taken by the Japanese Akatsuki orbiter. The story (https://en.m.wikipedia.org/wiki/Akatsuki_(spacecraft)) of how Akatsuki, after being pretty much written off as a failed mission, was brought back into play (and is now doing fruitful science) is fascinating all by itself. Akatsuki's orbit is highly elliptical, not unlike Juno's.
Pic processed into "RGB" by Damia Bouic from 283–365nm source data.
Edit #1: I've found out from Kevin Gill, one of the prominent JunoCam image processors, that this photo also uses infrared data captured by Akatsuki.
Edit #2: I've added a second pic, also processed by Damia Bouic. Look at the cloud detail. Lovely!
-Dave-
-
Shown today at the current American Astronomical Society meeting: this thermal infrared Juno image of Jupiter's south (I think) pole. Taken off a large screen projection. Yow, look at all those storms!
-Dave-
-
And here's the north pole. These are both JIRAM (Jovian InfraRed Auroral Mapper) images.

More OT re. Venus images from JAXA's Akatsuki orbiter: an explanatory piece at the Planetary Society website by Damia Bouic, the person responsible for reviving interest in the images.

This thread has a new home, and so here's a new JunoCam image from the most recent "Perijove" (flyby). Looking down at (relative to us) the planet's northern hemisphere. Initial RAW processing and compositing by Gerald Eichstädt with further processing, mostly color/tonal, by Seán Doran. Among the initial processing tools used is Mathematica (for scripting).
-Dave-
-
Good to see this got a new home!
Where can I book a trip there?

Me too!
Where can I book a trip there?
Maybe ask Elon Musk when (and how) he plans to get rid of his current personal Tesla. ;D ;D
Just to note: if you got as close to Jupiter as Juno gets you'd be fried into something with a charcoal outer crust and the inner consistency of marzipan. :o
-Dave-
-
Also from Perijove #11, the latest Juno flyby. Taken February 7th by JunoCam at an altitude of 12195 km above Jupiter's atmosphere, 49.2° North latitude. Processing by Matt Brealey and Gustavo B C.
-Dave-
-
One more from Perijove #11. Processed by Seán Doran after pre-processing by Gerald Eichstädt & Matt Brealey. "True color" according to Seán. Same location as previous pic here.
-Dave-

Here's a bit of Jupiter artwork derived from a JunoCam image taken during Perijove #10. Created by a fellow named Rick Lundh.

Not shabby. Via Eichstädt and Doran.
-Dave-

Really not shabby. This one is a blend of three exposures, also via Eichstädt and Doran. Makes Jupiter look like the eyeball of someone really hung over. :D Like the previous pic this is from Perijove #12.
-Dave-
-
Here's a Perijove #12 JunoCam image from the southern hemisphere, close in taking time to an Eichstädt/Doran image above. This one processed by Kevin Gill.
-Dave-
-
And here's an entire sequence of JunoCam pics from Perijove #12, processed by Gerald Eichstädt and Seán Doran. "Jupiter Descending," Seán calls it. Gonna be hard to top the images from this latest flyby, I think. They're almost too good.
-Dave-
-
Here's Kevin Gill's take on a Perijove #12 image of Jupiter's south equatorial belt. This belt occasionally disappears from view, as during 2009-10, due to clustering of ammonia ice clouds high in Jupiter's atmosphere.
-Dave-
-
Here's an example of a different take on JunoCam images, by a fellow named Don Davis with pre-processing by Mattias Malmer. I really like his gentler processing approach. From Perijove #12.
-Dave-
-
A pic from Perijove #7 (Sept. 2017), newly processed by Mattias Malmer and showing Jupiter's moons Europa & Io just above the planet's limb.

Juno's 13th flyby (Perijove) of Jupiter happened on May 23. Rather than directly post pics this time, here's a link (https://www.flickr.com/photos/seandoran/sets/72157694074056992/) to Seán Doran's Flickr page of initial image processing passes.
Perijove #14 will be Juno's last unless it gets a mission extension. Given its success so far I imagine the Juno team will get the extension if they request it.
-Dave-
-
Truly amazing images! Thanks for your postings, Dave.
-
Glad you're enjoying 'em, Mike. :) The JunoCam citizen scientists/image processors are all working on the Perijove #13 images. I'll probably post some of the more eye-catching renditions directly here.
-Dave-

Here's a contrasty take on a Perijove #13 JunoCam image of Jupiter's "South South Temperate Belt." Processed by Kevin Gill.

Perijove (Juno flyby of Jupiter) #14 happened on July 16. Lotsa great versions of new images floating around already, as processing techniques and workflows get further refined. I've attached one I particularly like, processed by Jason Major.
-Dave-

Perijove #15 was a couple days ago. Here's a pic from Seán Doran via a processing pipeline created by Brian Swift. And also a version from the same source data processed by Kevin Gill.
-Dave-
-
Another pic from the latest flyby (Perijove #15), processed by Kevin Gill. He says, "Map projected view of a white oval, an associated jet and a lot of WTF-type turbulence."
-Dave-
-
I see an interesting problem surface (to use a really ambiguous sentence); due to the popularity of the clearance slider in modern imaging, they may be applying a similar function inappropriately on these images as well. This results in added depth and drama, which, while cool for the general public, unfortunately is not so useful in analyzing the surface compound.
Would be useful if they also release 3d pictures to see if the suggested depth shadowing actually corresponds with reality.
-
The JunoCam images are mainly for the general public. Juno has other imagers that the planetary scientists use, mostly looking at wavelengths outside the visible spectrum. Some folks working with JunoCam pics do use processes that "kick it up a notch" while others go for a more subtle look. Some do both and also put both versions online.
There are 3D renderings of JunoCam images too, some using depth data from other JunoCam instruments. I haven't seen any of these so far that haven't looked overcooked, but I've heard the processes are getting more refined. We shall see…
-Dave-
-
JunoCam pics in 3D, you ask? Well lookee here: https://juno.observer/#/
;D
This is in beta. Texture mapping to come in a later release.

Perijove #16 was a couple days ago. Images were slower coming in this time, but here's one as processed by Kevin Gill.

OMFG! "Perijove 16" !
-
Perijove #17 happened on December 21st. Here's a sequence of images from it, in "true" and "enhanced" versions, processed by Gerald Eichstädt, Brian Swift and Seán Doran. (The former two provide automated processing pipelines that Seán uses as starting points.)
-Dave-
-
Here's a first (I think): a JunoCam image processing collaboration between Kevin Gill & Seán Doran. This is from Perijove #16.
-Dave-
-
Here's a Perijove #17 image, lightly processed by a fellow named Justin Cowart. "Taken from an altitude of 97,000 km over the south pole on December 21, 2018. The Great Red Spot is on the horizon, while the 'Little Red Spot', although devoid of color at this time, is passing immediately to its south."
-Dave-
-
And here's Kevin Gill's more enhanced take on a JunoCam image from the same sequence as the pic directly above. Lotsa lovely detail in this one.
-Dave-
-
Amazing image, the last one. You really feel like it's floating above you.

Forgot to post this last week. It's off-topic: the full "best so far" LORRI image of MU69 (aka "Ultima Thule"). Once New Horizons re-emerges from behind the sun relative to us (should happen later today, I think) the NH team will start bringing back higher res images. Because the spacecraft is so far away from us now (over six light hours) retrieving data from the recent flyby is both trickier in technical terms and just takes longer than it did with Pluto. I do like the bonus stars in this pic. :)

Yes! JunoCam and its team of citizen science image processors have delivered the goods for sure. Lots more to come too!
-Dave-
-
OT again: the highest-res full image of 2014 MU69 ("Ultima Thule") captured by New Horizons during its New Years Day flyby. I believe there may be some higher-res partial images yet to come… I've also included a colorized version of another image in the sequence based on early MVIC color data via the Planetary Society. NASA's own official color images will come later.
The bright line at the point where MU69's two lobes join together appears to be caused by the lobes pulling away slightly from each other, exposing cleaner underlying material (likely ice).
-Dave-
-
Fantastic.
-
More Perijove #18, this time via Eichstädt and Doran. This is a composite of three frames.
-Dave-
-
Here's a new one from Perijove #17 via Gerald Eichstädt & Seán Doran.
-Dave-
-
If somebody had shown me that image a few years ago and said "This is what Jupiter looks like", I'd have said "Do you have any of that stuff left?" :)
-
Yep, this last one does have a "lysergic pastel" vibe. ;D All kinds of small storms swirling around the closer (to the poles) we look.
-Dave-
-
I personally think they are going completely overboard with the local contrast adjustment. It suggests layered swirls in a more or less clear medium (like earth has a clear atmosphere) and yet the planet's sillhouette suggests nothing like that, and instead looks like completely dense, gaseous materials or fluids.
It's a giant, gaseous, comet eating monster is what it is. All the swirls are impact craters with the comets completely evaporated to their bare materials.
-
If you scroll through the images here, or at NASA's JunoCam site, you'll see a mix of heavily- and lightly-processed ones. Some of 'em go overboard to my taste but others, while still obviously processed, IMO look great nonetheless. I like this latest one a lot…the high contrast reveals atmospheric structure that's otherwise easy to miss.
The storms are very much that: hurricane/cyclone-like systems. Jupiter does get hit with plenty of asteroids and meteroids along with the occasional comet, but when they leave visible traces it's typically in the form of dark "bruises" as with pieces of comet Shoemaker-Levy 9 in 1994.
-Dave-
-
Another OT post. Due to Apollo 11's upcoming 50th anniversary, the space-centric image processing folks have been working with fresh high-res scans of the photos taken during that mission.
Here's one of 'em as processed by Seàn Doran.
Edit: totally messed up here. The attached pic is actually from the Apollo 17 mission. T'was processed by Seàn Doran, though. It's not just Apollo 11 images being re-archived digitally. Oy…
-Dave-
-
Lovely new rendition of the iconic image. I'd love to be able to purchase a 50MB file of that image. My HP 3200 would LOVE it. :)
Looking forward to seeing "Apollo 11". A pal just viewed a 70mm print in Vancouver. Envious doesn't cover it.
-
Probably gonna see Apollo 11 tomorrow. I'm glad all the high-res footage NASA shot is finally being presented properly!

Brief Twitter conversation on JunoCam image processing approaches:
Q: Do you know what the process re. colors is? I am never sure w/ "space pictures." Are the colors as the camera percieved them? As we would perceive them?
Seàn Doran: These colors exist in the source data but they are enhanced to assist details. In reality Jupiter is more muted.
Kevin Gill: Right. Here's a comparison I put together showing approximate true color and enhanced. While both are beautiful, I tend to like to bring out the hidden details and hues. [See attached pic.]
-Dave-

JunoCam image processor Björn Jònsson: "An orthographic mosaic from images PJ18_28 and PJ18_29 from Feb 12, 2019. Approx true color/contrast version and a version with enhanced contrast and colors. North is up. The circular spot slightly above the image center is at planetographic latitude 51.5 deg north."
