tallbear: "....However, the Cassin Tour will be altered in early 2006 and these opportunities may go away while others may appear.....
Uh... Say WHAT?....is this a branch to an entirely different series of encounters than the second half of the primary mission that they've been designing in (necessarily) obsessive-compulsive detail for the last decade? Did they have to retarget to make a close flyby of a Vogon Mothership? Or did they find a spinning blue telephone call-box floating in Saturn orbit? <grin!> |

Actually, rings folk really want to be in the ring plane... in the rings....
But that requires a Prometheus-Class nuclear/electric Ring Rendezvous Mission. I have a xeroxed article, probably from Journal of Spacecraft and Rockets, maybe from 15 years ago, describing such a mission. Spiral inwards, reach the rings, tilt the ion-engines out of plane and levitate about 10 km above the rings, continuing to spiral inwards. Mission to end 1,000 km above Saturn's equator. There was various discussion on ways to lower probes directly into the ringplane without risking the main spacecraft. I want... I want... <whimper> |
