I heard about a peak on Iapetus that may be taller than Olympus Mons on Mars. I was wondering if the RADAR instrument will be used in the January encounter to verify this. What is the maximum distance the RADAR can be used?

QUOTE (BruceMoomaw @ Dec 29 2004, 10:44 PM) (1) Ah. So, judging from the Planetary Society's description, radar scatterometry of Iapetus WILL be obtained during this flyby. (By the way, Jason, you never did confirm for us that Cassini missed some of its planned measurements -- including the radar -- during its recent Dione flyby, or explain what caused the problem.) (2) It turns out that some researchers have been WAY ahead of us in noting both Iapetus' nonspherical, lumpy shape and the apparent implication that this moon has had the very devil knocked out of it at some point -- and that its whole developmental history has been radically different from that of Saturn's inner moons: http://protostar.aas.org/publications/baas...dps2000/329.htm http://www.lpi.usra.edu/meetings/lpsc2000/pdf/1596.pdf http://www.lpi.usra.edu/meetings/lpsc2000/pdf/1660.pdf Bruce, thanks for the excellent links! You've got to love the internet...during the Voyager days I waited patiently for every issue of Sky & Telescope and Astronomy magazine to come out so I could see the new images and read about the exciting discoveries. Now it's a matter of hours / days before we get the information. And not just that, we get to converse with some of the people who are working with the craft / data! My sincerest thanks to all of you who are making this happen and keeping us informed! And thanks to Doug and Bruce for the best forum on the web!
