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.

This may serve as a small status update.
I'm working on PJ3 map products: In the meanwhile, I've found and resolved two glitches, but there are still several more issues to be resolved. In this version, longitudes have not yet been aligned. I'm currently trying to determine Juno's rotation period from the images. My initial estimate of 30.242 seconds didn't fit well. Therefore I've determined the pointing for each images separately for the above animation, which led to a shift of longitudes as a side effect in this approach. A better preliminary estimate of Juno's rotation period seems to be 30.330 seconds, on the basis of PJ3 images 103 and 104. I'll narrow this further down, before rendering the first set of maps in higher resolution, which will not yet be de-Lamberted. An other issue I've to resolve is a glitch in the rotation matrix for the de-Lamberting model, and a better approximation of the surface normal. |
