Juno is set to flyby of Europa on Sept. 29, 2022 (PJ45)
I can't wait to see the results of this flyby! Sadly not much information is available online. Jason Has a beautiful animation of encounter on youtube. https://www.youtube.com/watch?v=r9bx1GcoqEE...nel=volcanopele |

Found a place to put the product I produced (there are subtle differences from what I posted earlier as I worked to improve the control point network(s):
https://flic.kr/s/aHBqjA9D8g Found a much better way of tying these images together in ISIS. First I created control point networks for each observation separately using Autoseed then I registered each point using pointreg. This control point network scheme is similar to what we do with CaSSIS, which makes sense given that both are similar push-frame cameras. so I have four separate control networks for the four images. I then used cnetmerge to combine the two. It was important to make sure that the points in each network have different names, so when they were generated by autoseed, the points have the observation name as a prefix, much like CaSSIS. I then used qnet to interactively tie together the four networks by finding common points between them. The perspective shift and the pointing offsets made it a lot less messy to just do this by hand. This also gave me a chance to fix some points to a Voyager/Galileo basemap. The biggest limitation to this process was the fact that the basemap isn’t perfect and there are clearly offsets between the higher resolution images in the mosaic and the lower resolution background image in the region from Galileo G2/C9. This is something that the JunoCAM observations will be able to remedy to have a better product for Europa Clipper planning. -------------------- &@^^!% Jim! I'm a geologist, not a physicist!
