for CR3BP, NASA uses EMR as the term for Earth Moon Rotating Frame. although I like EMB Earth Moon Barycenter or EMBR (EMB rotating) For conversion of EMR units to...

#others using AWP might enjoy this NRHO 9:2 Halo orbit state to play with. gatway92 = [1.021325, 0.0, -0.181619, 0.0 , -0.101736, 0.0 ]# semi-stable Apolune NRHO 9:2 orbit state

planetary data for moon is wrong for mass moon = { 'name' : 'Moon', 'spice_name' : 'MOON', 'SPICE_ID' : 301, 'mass' : 5.972e24, # mass of Earth not moon 'mu'...

For CR3BP problem, most people are using mu=.0121505845 But the value in this code is mu=.012277471 IE. Is there something about this difference I need to understand? NASA has calculated...

I'm building spacecraft controls, called Xcontrols and have created many widgets. I'm willing to move them to the style you use here for Pygame_Widgets I would rather just off load...

Note: Current solve_ivp needs more accuracy near the moon, where the derivatives are changing very fast you will need to break up time evaluation into discrete t_points with t_eval=t_points t_points...
