How do I get a communication satellite into a highly eccentric polar orbit around the sun, oriented orthogonal to the ecliptic in the most efficient manner?
The idea is that this orbit would create a relay that would be outside of the ecliptic and would have a direct line of sight to almost anywhere inside the ecliptic.
Thoughts so far:
- How can I use Jool to put a spacecraft into a solar polar orbit?
- I need a high altitude to efficiently perform the inclination change
- I can use gravity assists only while I'm more or less still in the ecliptic ... so I should do the inclination change starting with the last gravity assist
- If my eccentricity is not circle-ish after I do the inclination change I have to rotate the argument of the periapsis around the sun
Which leads me to the following order of maneuvers:
- use Duna to get into a highly eccentric solar orbit that encounters Jool
- use Jool to assist with the inclination change to solar polar orbit
- make orbit circle-ish
- fly over the sun and reduce the periapsis until the orbit is highly eccentric again - this time its orthogonal to the ecliptic though
- optional: fly to periapsis and reduce the apoapsis to around 30% of the maximum range of the used communication antennas.
My actual question: Is this the most efficient way and if not what could I do to reduce the ΔV cost even more?
