Updated my image site with PJ60 images (and FINALLY got around to adding the images from PJ55):

https://pirlwww.lpl.arizona.edu/~perry/Juno/

For PJ55 and PJ60, images are magnified by 2x

Some IDs on those plumes. The two seen in Brian’s post from 1:20pm yesterday are Prometheus (left) and Seth Patera (right). Seth has been experiencing an intense eruption with new flow field since late 2022. In the other post, with the Nusku plume deposit, that plume is from Mixcoatl Fluctus.

Oh the one in 45 is Volund.

I will note that the current tour SPICE kernel is on the NAIF kernel site. If you know how to use something like spiceypy, one could create a python script that gives you all the flybys.......

I will say one good thing about this and that they finally solved my biggest complaint: why have another rover/helicopter to deliver samples to the MAV when you have a perfectly good rover that can get you most of the way there. Yes, that depends on Percy surviving until then, but it would eliminate some of the duplication of effort. That being said, why not just have the MAV land at Midway and let the rover complete its mission of collecting samples between where it is now and there?

60_52 and 60_53 done.

So neat to see Xihe in color after 17 years!

Before the deluge, that's Seth Patera. It has been VERY active recently in JIRAM data.

JunoCam paper about the Europa images is out! Congrats to Bjorn on the co-authorship!

Nicely done, Phil! I take it the title and heading font is from the template because I couldn't find a way to edit the formatting of those.

Can you do a plot where the SRU image is one rotation later for PJ57? The one you have plotted would be too far west and right on the terminator for Jupiter-shine. I would think that the SRU image is either the rotation after that one or two rotations, though I personally really hope that it is one rotation to get all of Tonatiuh.

JIRAM M-band composites from two of the sequences. JIRAM stared at Io for several hours during PJ51 so the difference in geometry makes it hard to make a single composite so I'm processing these one sequence at a time. I'm also only going to bother with the 2 ms data, not the 4 ms stuff. Yes, the 4 ms data has better SNR but I can avoid much of the smear with the 2 ms stuff and I have to constrain what I'm working on somehow. Any mismatches you see are due to the fact that I started using my crude (but reasonably well controlled) Io control network with this data set and the background map is still the USGS basemap.



I see past me's comment about serial numbers and this will likely lead me to edit the RDR labels during ingestion on my end so that I can still use my control point network on them because there is NO WAY I am redo'ing all this work...

JIRAM M- and L-band composites from PJ53:

The PDS release calendar is here: https://pds.nasa.gov/datasearch/subscriptio...ndar-2024.shtml

As Mike mentioned, PJ53 (and 51) data was released to the PDS a couple of weeks ago (I'll post my processed versions of that JIRAM data on those pages in a minute). PJ57/58 PDS data (and thus JIRAM data) should be publicly available on the week of September 24. Mike noted that the schedule is a bit variable so that date is approximate though teams seem to be releasing data a few days to a week early. Also they did change up the release cadence a bit... Last year it was 3 orbits every 4 months, and I was prepared for the PDS release at the end of this month (even asked for time off from HiRISE for it...).

Just two different methods of processing the data. I use ISIS which has the issue of it trimming the images off at the limb when you map project them. But on the other hand they are very useful products for dropping them into ArcGIS.

Improved versions using a global control network

Looks like Masubi lives!

First attempt at the second Jupiter shine image. Need to work on the control network a bit more on this one so this is a first draft.

First pair of images complete:

BTW, not the first time we’ve seen specular reflection at Loki:

Full images aren't up yet, but the green filter of one of the crescent sunlit images is now available:



Reflective Loki! the Xihe plume! Jupiter Shine!

Thanks for the heads up Mike. I did let me D&D group know that I might be busy Sunday evening just in case... My legally distinct "Han Solo" character can sit out a session.

LPSC 2024 conference program is now available along with abstracts is now available:

As is typical for me, here is a list of Io-related abstracts:

Abstract obviously focuses on the PJ57 data, remember these were submitted ~January 9

That's right! After 17 years I make my glorious return to LPSC... as a virtual poster but hey that's more than nothing. And the best abstract one can do when one still has RSV or the flu, still not sure which it was

The resolution will roughly match JNCE_2023364_57C00023_V01, so the second of the images from the last encounter, and at a similar emission angle, but at higher phase angles (110° vs 90°). JNCE_2023364_57C00022_V01 had better pixel scale at Loki, but at a higher emission angle.

With the timings and TDI settings Mike provided above, here are preview images (combining USGS basemap with PJ57 data, greyscale is USGS basemap and a simulation of Jupiter-shine):

Even for my simulations, I account for the JunoCam FOV by looking at the predicts in Cosmographia and trimming off the excess in Photoshop from the maps I reproject in ISIS.

as far as the timings go, 17:48:30 is even more marginal than 17:50. It does do some gap fill east of Shamshu Patera but it misses Masubi and barely gets Janus. If that's just how the timings work, I mean, that's still really nice resolution at Shamshu and points east. 17:53:30 looks pretty good though maybe reverse the TDIs? 17:53:30 is good for a nice full global shot in sunlight.

Regardless, I'm sure these will be amazing. I'm so thrilled that we are getting such great sub-Jovian/leading-hemisphere coverage!

comparing 55C00035 with 57C00030 and 57C00022, I get roughly similar pixel values for places like around Fjorgynn Fluctus. Color still looks better for the PJ57 images. No apparent signal in BLUE in the orbit 55 images, it looks to be almost entirely noise. for PJ57, the darkest features like Guawa Patera and Fjorgynn Fluctus and the brightest terrain shows up (bright material near Gauwa and Fjorgynn, and around Acala Fluctus). I presume that this is a factor of noise, reducing effective resolution. So PJ57 data, particularly 57C00022 looks great, but the effective resolution is still reduced by a factor of 2-3 compared to the dayside. but that drop of resolution still makes it better than Galileo/Voyager data.
