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?

I can't get JPL's solar sysyem simulator to work for Cassini after July 2 so I found another way to simulate the view. View from sun gives sunlit side
http://space.jpl.nasa.gov/cgi-bin/wspace?t...vmul=-1&bfov=30 view from saturn gives phase angle of 110 degrees. http://space.jpl.nasa.gov/cgi-bin/wspace?t...vmul=-1&bfov=30 110-90=20 which should be longitude where terminator crosses equator on your map (sunlit to left) View from Titan has phase angle of 95 degrees which is close to phase angle at closest approach (94 degrees) So the view from Titan should be close to what Cassini will see at closest approach. http://space.jpl.nasa.gov/cgi-bin/wspace?t...vmul=-1&bfov=30 Would be simpler if they updated the simulato so you could use Cassini as the viewpoint after July |
