you obviously got a kick out of this!

Thanks for the experience sharing. I haven't tried it in a planned way before, I only managed to

get it right occasionally. I really got the idea from Dan's IO scenario with the DG, when you need to

pick up Joe Drunk from orbit.

What I would like is to come up with some sort of theoretical model, equipped with sufficient

formulae to be able to calculate the thing for any planet and any orbit. So I guess we're talking

angular velocity of a target vessel, which depends on it's orbit, which in term depends on the its

altitude and the mass of the planet.

Now the real challenge as you also said is to get the orbital planes aligned (which can be easy

enough, with the right launch time and azimuth) and to put the ship into a proper orbit. Which is

my next question. How do you go about targeting your periapsis and apoapsis? I usually just

takeoff and take whatever orbit I get into, or use the dg's launch program. I don't have an

adjustable pitch program to be able to get into any kind of circular orbit (fuel permitting of course).

I tried to, but I end up with a need for an iterative formula for pitch adjustment, because the pitch

angle determines the vector of the thrust and this has to be constantly adjusted depending on the

current state of the ship (alt, pitch, vertical and longitudinal component of speed).

I'm low on time, but I will give all this a try, as soon as I can.

Thanks again,

Janez
