The Hyperion gravity data wasn't obtained through recorded data that could be played back -- it was obtained through extremely precise two-way Doppler tracking, and thus cannot be retrieved. Fortunately, they did manage to get the earlier gravity tracking session at 8 to 6 hours before closest approach, although the second, more precise session at about 2 to 3 hours after CA has been lost -- so they'll still get data in Hyperion's mass, but just not as precise as had been hoped. (Something similar happened during Galileo's flyby of Amalthea -- with the result that they got good data on Amalthea's density, but lost their hoped-for data on its internal distribution of mass.)

I took dilo's great animation of the Hyperion approach and modified it slightly, so that it plays constantly on a loop - backwards and forwards. This allows the viewer to get a better appreciation of the moon's complex topography.
Well, it works for me anyway!

Quite the dancing Hyperion a couple of posts up. I've updated my Tethys map now to include the excellent CICLOPS mosaic that Volcanopele had worked on. The current version is at http://laps.fsl.noaa.gov/albers/sos/sos.html#TETHYS.

Great work!
I always save every update you make and compare the differences with mapping done on the moons. I love seeing this puzzle started by Voyager and Completed by Cassini. |
