I have sim tested the Apollo 8 project at this point pretty well.  There are some hairy edges but I think it is time to take some risk; it is a complicated mission. There are many parts; duration in Kerbin orbit, retrograde orbit of Mun, return.  I will also be testing the LM for docking and such.  Lot's of sim failures there that were eventually corrected  by using the current RCS thrusters (FASA ones were behaving oddly). Here we go... Apollo 8 (Tamphia[p], Irra[p], Zellenna[e]) Ascent: 200km, 0 deg 50% Reached orbit.  The clock is not counting for some reason (may be a bug or require Munar orbit).  Also, the Fuel cell seems to not be happening as well.  This could pose a great problem. I have turned on the LM fuel cell and at least stopped losing power.  Very odd. On our way to Mun, although the power issue remains.  Unknown what may be causing this since they worked fine in the sim. Going to warp to Mun SOI (worried about this since that is when they would die from power problem).  Than adjust for incline and periapsis. We have a 179 deg incline (good) and a 125 kmn periapsis.  So I am going to release the 3rd stage and go into orbit with the CM Module. That worked.  Need to be careful to turn off RCS before warp, it used up a LOT of monopropellant. It does not appear the countdown clock is working in  this orbit either, so I will just approve the contract if I have to.  Let me hang out a bit here.  After all, I am in Munar orbit! 255dV to Return from 125 km orbit of Mun. Mission was accomplished but did not complete so I completed it manually, but it was a solid mission! <Apollo 8> We now have the Apollo 11 Mission.  The Mun landing is upon us.  I left the Apollo 8 LM in orbit to test with it before I launch 11.
