1. Has anyone sorted out why the hexagon persists? and are there any similar features on other gas giants?
2. How far ahead is Cassini's orbit plotted? and how (and how often) is an adjustment made to the trajectory? It is mostly empty space, but it must be an amazingly complex calculation to make sure you don't hit anything, yet still swing close to your targets.
even when i have a terrible week, like the one i just had, coming to this site and looking at the breath taking images helps. the technology we have that lets us see these vistas, and the remarkable skill of the team that brings them to us is mind boggling. in the grand scheme of things Saturn is one of our closest neighbors. yet so much was hidden from us until we sent our remote eyes and ears out there. contemplating the detail of this huge vortex makes a really bad day better for me.
