Hello all,
I have spent an hour searching the forums and cannot find an answer to my question. Maybe those with more experience can help. First, I will say that I have successfully used transX to go from the earth to: the Moon, Venus, Mercury, Mars, Jupiter, Pluto, and Saturn via a Jupiter sling. I am pretty confident with using transX in general.
Now here is my problem: I used transX to get from Earth to Venus. I am now in a polar around around Venus with a 90 degree inclination relative to the equator, with an altitude of 300km (I'm doing the Venus Weather DG-IV mission). Now I am having trouble using transX to plan my return trip from Venus orbit. I have used transX from LEO, so I am familiar with the differences between that and a ground set up.
For the life of me, I cannot figure it out. In step one, I set target to escape, with Venus as the maj. Second step, I set target to Earth. Now it tries to set up a sling-direct! With the sling direct plan, I cannot change the usual variables of outward V and plane V. So I disable autoplan. I choose no plan, and I am able to access the usual variables. However it does not give me any information on when to and where to burn! It does not change step 1 in any way (with the time to Pe, dV, time to burn.....) and it does not allow me to view the target with the "x" in normal maneuver mode. I have tried changing every option in an attempt to fix this, and it seems to be almost random in its effects...none of which give me my burn plan. The only time I was able to get the program to act "normally," I entered maneuver mode, and my dV sudden was increased by 30,000 m/s! :blink: I assume this has to do with my orbit around the sun, as I cannot see any other body that would require such a large change in energy!
Then, I thought that I had found a magic combination....turns out changing the parameters in this case had NO visible effect on my trajectory what so ever. So I turned the MFDs off, quicksaves, and restarted Orbiter to reset the MFD. Same thing, over and over and over.
I got so frustrated I attempted to "eyeball" my return :suicide: Yes, this did not work out very well. I feel like I am missing something so simple. Something like: one cannot return to earth in a polar Venus orbit, so the program wont function. Either that or transX borrows its logic from wireless network technology (IE based on voodoo).
So if anyone has done this before, and could give me a little advice on what I am doing wrong, it would be much appreciated!
Good day, fair orbiteers.
