00:08 <queqiao--> <P​im​ie​nt​o> Thanks for the feedback. I have actually just finished the mission (Skopos satellite, now in maintenance mode). I simulated different peri & apos and I could have reduced the apsidal precession , but this value is good enough right now for this mission. It will drift around 70 degrees, but given the position it is right now, it will keep covering the area with good signal. Rising the periapsis required one extra maneuver,

00:08 <queqiao--> so I discarded that option to make the mission easier. Maybe I will try for the next one. Thanks again !

03:33 <queqiao--> <T​in​km​an​> I’m looking to try to solve a problem where I move from 1 orbit to another orbit through 1 or 2 burns and reach the 2nd orbit at a specific position and speed at the end of the burn. Where would I start to be able to run those calculations? (Probably by brute force)

04:12 <queqiao--> <C​la​ye​l> like a hohmann transfer? can you clarify?

05:16 <queqiao--> <K​ag​a> is it just me or is mechjeb's circularization feature not reliable in orbit with principia? it always overshoots and points backwards and repeat

15:34 <queqiao--> <G​oF​or​PD​I ​(l​es​s ​dr​ag​=m​or​e ​fa​st​er​)> Google Lambert’s Problem, that’s what you have described

17:54 <queqiao--> <P​im​ie​nt​o> My 200km x 40150km, almost 12 hours orbital period, 63.4 inclination, Molniya orbit satellite has disappeared after 9 months providing TV services. Is this possible in Principia? If so, what would be a "safe" periapsis in this case? Also, Increasing the orbital parameters simulation to, for instance, 365 days, would I have detected this? Thanks !!

17:57 <queqiao--> <e​zs​na​ck​> 200 is very low, the higher the pe the better xd

18:01 <queqiao--> <P​im​ie​nt​o> I am launching it again, actually now 2 of them, with 350km, to be in the safe side. So, regarding my question, given that low orbit and enough time, a crash is a feasible explanation for it disappearance, right?

18:03 <queqiao--> <C​la​ye​l> or the russians took it

18:07 <queqiao--> <e​zs​na​ck​> (typical molniya orbits have an eccentricity of around .7 btw, a lot higher PE than you :V)

18:21 <queqiao--> <P​im​ie​nt​o> I have answered my own question, indeed had I simulated longer I would have seen that it can actually crash. I love Principia, I am enjoying these new challenges very much :-). https://media.discordapp.net/attachments/480397772248580098/1387135510119448767/image.png?ex=685c3e1d&is=685aec9d&hm=fc98256fdfe26106f50d88ece6a95901b31344bed4c2204db3def57c8fe278da&

18:22 <queqiao--> <r​ap​to​p ​| ​²³​⁹P​u ​po​we​re​d> Imagine the shuttle trying to nab a satellite in that sort of orbit

18:30 <queqiao--> <P​im​ie​nt​o> That would make a good program/missions . Randevouz, capture and either deorbit or eject to the sun a competitor's satellite
