CICLOPS' Rev 49 Looking Ahead page is up. Highlights include a fourth monthy Voyager-class encounter with Tethys with 500m resolution over Odysseus (finally!)
Detailed mosaics of Rhea's prominent ray crater and points west are on tap for Old Scabby's second closeup. This should be a really cool periapsis passage to tide us over until the 10th of September. -------------------- ...if you don't like my melody, i'll sing it in a major key, i'll sing it very happily. heavens! everybody's all aboard? let's take it back to that minor chord...

i have to admit im short in the theory department. im only interested if they land someplace!
this all goes back to shoemaker-levy 9 days, now almost 15 years ago. breakup requires passage within about 1.5 jupiter radii of the surface of the planet, and something similar for saturn, except the density plays in somehow. the articles by asphaug, benz and others back in the mid-1990s tell all, otherwise start with the Schenk paper in Icarus in 1996 which includes such references. i dont have a copy with me at the moment, alas! cheers, paul -------------------- Dr. Paul Schenk, Lunar and Planetary Institute, Houston TX
