Wing Ip just had an interesting Iapetus-related paper published in GRL.

Speaking of New Horizons, how far out can it productively study a KBO? I understand 2 additional flybys after Pluto are possible, if we get real lucky and have a larger choice of follow on targets, how far out can we go?
It seems the larger objects would be preferable to the smaller ones, but if 2 objects are situated fairly close do we take the surer bet and visit them, or would we gamble on a much larger object right at the limits of New Horizons power supply and camera light levels? With the fascination of the Iapetan ridge system, and only spherical (ie. large) KBOs having even a tiny chance of having a comparable ridge system, can we 'nudge' the acceptable maximum range of NH a tad? (lower data rate back to earth, using the NH attitude control system to track the dimmer objects for longer exposures, etc. ? Voyager II learned new tricks on the way to Neptune, can NH do the same out to 200 AUs?) |
