Anonymous Explorer writes "The Cassini-Huygens probe is set to fly by the largest outer Saturn moon of Phoebe today. Cassini will be roughly 2000 km from the surface of Phoebe at 1:56 Pacific time Friday, June 11. Thats pretty darn close. The newest images of Phoebe are already thousands of times better than the previous ones taken by the Voyager 2 mission in 1981. Phoebe is interesting in that it maintains a retrograde orbit around Saturn. This has lead to the hypothesis that it is an ancient asteroid that has been captured by the gravitational pull from Saturn. Phoebe may provide some important insights into the composition of early building blocks of our planets. Phoebe was discovered in 1898 by American astronomer William Pickering. As always, discussion about this mission can be found at #cassini on irc.freenode.net."
