With the nes period findings, the NH mission disign still remains rather uncomplicated with regards to satellite placement during the flyby. Granted the configuration of the satellites does not repeat exactly every ~70 days or so, with the near resonance exhibited, the 2 new sats will still be constrained in their posible positions. (working this out in my head) it seems the sats will be slightly short of their last position every ~70 days. (imagine the whole system lining up slightly earlier every time the objects 'reclock')
For an apparently narrow range of possible arrival dates (assuming a nominal launch, evaluating the arrival dates consistent with Pluto and Charon optimal positions for good views of the new satellites still should not devolve to a plethora of possibilities. |
