Sad Space Boy on Saturn didn't really have any family left to say goodbye to when we departed Earth, they were all either gone to the dust of time or so very distant and remote as to be beyond his grasp. This is not to imply a lack of caring on his part, it's just well...he was cold before he ever left for that heavy world of Lead. The few remaining "family" members he had should be spared the burden of knowing he is parting anyway. Space railway hopping on Orbital Launchpads is a sad affair for some, but there is great promise and great loss alike in Space.
Symptoms of leaving Saturn's orbit include, but are not limited to:
Sudden Elation
Body Spasms
Abnormally high body temperature
Violent fits of Nausea
Radiation burn
