One of Saturn’s rings does housecleaning, soaking up material gushing from the fountains on Saturn’s tiny ice moon Enceladus, according to new observations from the Cassini spacecraft.

“Saturn’s A-ring and Enceladus are separated by 100,000 kilometers (62,000 miles), yet there’s a physical connection between the two,” says William Farrell of NASA’s Goddard Space Flight Center in Greenbelt, Md. “Prior to Cassini, it was believed that the two bodies were separate and distinct entities, but Cassini’s unique observations indicate that Enceladus is actually delivering a portion of its mass directly to the outer edge of the A-ring.” Farrell is lead author of a paper on this discovery that appeared in Geophysical Research Letters January 23.

Supposedly the slingatron is one of the more sound and more thoroughly reviewed of potential hypervelocity systems, but there are a few problems I cant figure out a way around. Suppose you use conventional or gas bearings. The best Ive seen is .001 for a friction coefficient. At a few km/s (below ..
