Ultimately I think I'll settle for seeing what impulsive accelerations I need to apply at the two points, and get a quick estimate for minimum deltav thusly. Of course, real engines can't apply Dirac impulses of thrust. So I'll then need some kind of fudge factor applied to the previously...

That's actually looking very good. So then, how much deltav does the hypothetical ship need for the maneuver? There's some deltav to go to the elliptical orbit around the Sun (so that's fine, I think I know how to estimate that, given some target green ellipsis), then there's deltav burn B. How...

Pure brachistochrones seem a bit unwieldy, yes. That's why I want to know what eqs to play with and tune a transfer that's reasonably fast, reasonably cheap. Main issue I have, really, is getting on the parabolic trajectory a bit sooner than perihelion. {EDIT:} and really, that's the ultimate...

That's more useful, thanks again. Any chance I can see the math behind the diagram, and get some deltav values? For example, when you mean first burn at vector 1, you mean just enough to escape Earth ((sqrt(2)-1)*orbitalVelocity(Earth), then for escape vector 3, just enough extra deltav to...

Oh. That sounds like it might actually be useful. I'm intrigued by that idea, can you tell me more about it? As for my goal, it's completely stupid. Basically I encountered a post from "Jules" on the RPGMP3 forums, and it inspired me to write a crossover Prometheus/Rendezvous with Rama ripoff...

Thank you for the time, but it's not quite what I'm looking for. Not interested in flying around in Orbiter just yet. Still at the phase where it's all meaningless buttons and panels ("open another orbit MDF" hth?), and it seems just needlessly complex when there are automatic Hochmann...

Ok, ultimately I'm interested in a rendezvous with an object moving on a parabolic orbit scenario, but baby steps. What options does one have to go from some circular orbit around the Earth to parabolic 'around' the Sun? As in, ways to actually plan to go from one orbit to the other, and compute...
