I thought that it was time to start a new thread devoted to the JUNO Jupiter
Orbiter mission. This New Frontiers Mission #2 seems to be a "stealth" project with little information available on the Web. In fact, the official NASA JUNO web site is quite pitiful. It contains the minimal amount of information on what seems to be an intriguing mission, in terms of both science and engineering. Does the UMSF community have information on this mission that has not been widely seen before? Another Phil |

for those close-approach tables, you really need spice kernel files, but I believe that JPL Horizons also has this capability Currently I am using custom "brute force"method. It has moderate accuracy but still suitable for event search. I can summarize my results as following "Top Lists", 5-10 closest approaches for every Galilean.

Most promising encounter is one with Callisto (2016-Dec-22), close enough and just within first eight Juno's orbits. Assuming 3 degree FOV and 1024x1024 CCD, we may expect a spectacular view of that moon. Something like this: ![]() |

Assuming 3 degree FOV and 1024x1024 CCD, we may expect a spectacular view of that moon. Sorry, but since Junocam has a 70-degree FOV none of these approaches is going to be spectacular. (All this was discussed upthread.) If there happened to be one closer than, say, 50,000 km, it might be worth doing, but even that's 40 km/pixel, only a 2-3x better than HST can get. -------------------- Disclaimer: This post is based on public information only.
