raptop changed the topic of #principia to: READ THE FAQ: http://goo.gl/gMZF9H; The current version is Fréchet. We currently target 1.5.1, 1.6.1, and 1.7.x. <scott_manley> anyone that doubts the wisdom of retrograde bop needs to get the hell out | https://xkcd.com/323/ | <egg> calculating the influence of lamont on Pluto is a bit silly… | <egg> also 4e16 m * 2^-52 is uncomfortably large

Acer_Saccharum. — I generally would go about that by launching into the plane of the moon, and from there planning an approximate ejection burn in ECI
<discord->
Acer_Saccharum. — Then switching to SCI to reach the appropriate final aphelion or perehelion
<discord->
Acer_Saccharum. — Then switching to the destination-planet centered inertial frame to fine tune the approach
<discord->
Acer_Saccharum. — Note, the maneuvering frame is always ECI, I'm changing the plotting Grand frame to give me the best views
<discord->
Acer_Saccharum. — Midcourse corrections, if needed, can be done in the SCI reference frame
<discord->
Acer_Saccharum. — Alternatively if your launch site is at a high latitude, launch at sunrise or sunset into an orbit that follows the terminator

Acer_Saccharum. — Alternatively if your launch site is at a high latitude (more than ten degrees greater than the moon's current inclination), launch at sunrise or sunset into an orbit that follows the terminator (edited)

egg. — @Falcon @Acer_Saccharum I recommend using the <B>CSA reference frame, where <B> is the planet to which you want to get
<discord->
egg. — this is the equivalent for solar orbits of the target LVLH frame which you use for rendez-vous
<discord->
egg. — using <B>CSA means that you can see whether you reach the target planet trailing/leading it, you can understand where the sun is at that point, etc.
<discord->
egg. — which you cannot see in <B>CI
<discord->
egg. — @Damien, @lpg, any interplanetary advice?
<discord->
Falcon. — I did barycentric and attempted to launch into the plane of Mars like you would the moon
<discord->
egg. — don't use the barycentric frame, it's mostly useless tbh
<discord->
Falcon. — Will do

egg. — you probably want to launch into the plane of the ecliptic, so the reference plane of the ECSA frame
<discord->
egg. — I should rename the <secondary>C<primary>A frame, it's a terrible name
<discord->
egg. — maybe ECSO, for Earth-centred Sun orbit?
<discord->
Falcon. — Once I get home I will have to see which reference modes that is and such
<discord->
Damien. — It's been a while since I last did an interplanetary mission tbh but using the navball midline in BCSA is better than using the moon imo
<discord->
egg. — yeah definitely the moon is irrelevant here
