Jovian Galilean Moons, Europa Flyby, Cassini State and Resonance Solver
Solve Galilean satellite positions with Meeus/Lieske E5 series, chart the Laplace-resonance libration, scan mutual events and eclipses, model a Europa Clipper-style flyby with patched-conic Δv, and solve Jupiter Cassini states from J2 oblateness precession.
