Hey everybody, I want a flag on Pluto (using RO,RSS,TAC-LS,RT,kOS etc) and started by calculating different scenarios. It turned out, that Pluto is giving me some serious headaches. The biggest problem is the unneglectable inclination relative to the eclipse of 17° combined with Pluto`s excentricity. ---- I`m German, hope you understand what I write, feel free to correct me --- Scenario 1 is just a Hohmann Transfer to meet Pluto when he crosses the ecliptic. Scenario 2 is about meeting him at his Periapsis. I do not consider any swing-by maneuvers, because there would be to many odds... So in order to calculate Scenario 1 I need to know my speed relative to Pluto, when I meet him at the Ascending Node so I can calculate the burn that keeps me in Pluto-orbit. But here`s the problem: how do I know Pluto`s distance from the sun and his speed when he crosses the Eclipse? Is there any "general" equation that would be usable for other inclinded planets, such as Mercury as well? Scenario 2 would require to burn my spacecraft`s apoapsis to Pluto`s Periapsis. His speed and my speed at that point are easy to calculate. The advantage of this scenario would be a much shorter flying time, and therefore less weight (less life support). What I save on Life support could be added as fuel and increase the Delta-V for the "Flip-burn". On the way back to Earth I wouldn`t have to do the flip burn and use the Delta-V to reduce speed just before Earth-reentry and keep g-forces lower, since I would not have to dive too deep into Earth`s atmosphere. But how do I calculate the "Flip-Burn"? Flip-Burn", because I would stay at the Eclipse until intersecting Pluto`s orbital plane and change the inclination ("flip" my trajectory) there. How do I calculate my speed and my distance from the sun when intersecting Pluto`s orbital plane with my AP at his PE ? Any hints are welcome. Maybe someone has done and posted their math before, but so far I couldn`t find any. Cheers, Whateverest
