I'm not sorry to see Moon go. Let's face, s/he was always just a hanger on. Sure, there were the tides and being the object of many a love lorn poet or song writer, but face it, beyond that veneer of a happy go lucky celestial pal to Earth there is the real Moon. No atmosphere, weak gravity, a lifeless, dusty and dead rock, revolving around and sponging off their rich relative. So if that ingrate of a companion thinks the grass is greener in Jovian or Saturnalian orbits, well don't let the door hit your dark side on the way out.
