A lot has happened and it seemed like a good time to start a new post. We will be staying in 53 day orbits until the project has a full understanding of the risks that may or may not be associated with reducing the orbit period to 14 days per our previous plan.

Well, in order to solve the question about whether relativistic effects might be relevant or not, I did a short SR calculation assuming velocities up to 1e-4 the speed of light, and got a relative effect of about 6.8e-9, which can't explain the offset, which I resolved only up to about 1e-7.
The effects I'm considering are often assumed to belong to SR, but they are better described by GR, like the twin paradox. Eventually, the presumed fluctuations of the angular velocity seem to be of a different cause, either some spacecraft operation, which I've considered as less likely during flyby, interaction with Jupiter's environment, which looked also less likely at that height, unconsidered image processing effects, or some inaccuracies in the data, which I also assumed to be considerably smaller. |
