This reminds me of the Technology Connections fridge rant video. Similar arguments all around, the dumping effect of cold out of a vertical fridge is pretty crazy to watch with a thermal camera.
Seems like a generally good idea, the satellites already need to use star trackers, they need an almanac of what should be there so deviations need to be tracked.
I can entirely see the military perspective though, this is almost a direct challenge for any adversary that any maneuver you perform, we will know about it.
That could very well be what the quantum uncertainty principal is, floating point non deterministic errors. It also could just be drawing comparisons among different problem domains.
The Parker solar probe gets much closer than the solar orbiter, 0.046 AU vs 0.28 AU respectively. The successive Venus flybys are to drop it increasingly further into the sun's orbit to take solar atmospheric data on quick flybys while the Solar orbiter is more for spectrograph measurements of the sun's corona, just different mission sets.
