I'm on KSP 1.11.2 (Since mods stopped my game from loading in 1.12) and I have a bunch of the near future mods (specifically near future spacecraft, propulsion, electrical, and solar). I think I have all of the required other mods to keep those running, but they just aren't showing up in-game. Any reasons/fixes for this? To add on, I think the near future stuff is on the latest version (not 1.11.2), but is there any way to find older versions on the Near Future mods that are compatible w/ 1.11.2? Another edit, I found a mod on Curseforge in version 1.11.2 called "KNES-1" and downloaded that. It doesn't work for some reason.

Ok, I think I have a better idea of what to do now. Thanks for the help! I got the contract done!

I think you misunderstood a bit. I can easily get into low orbit around KERBIN, but I mean getting into low orbit around KERBOL (the sun) that's difficult.

So, I'm trying to get to a low-Kerbol orbit since I have a contract asking me to get a bunch of scientific measurements from there and also because if a process all of that science in a mobile lab, I can probably upgrade everything I can on my R&D facility level. My current problem is that I run out of fuel on my last stage when my peristalsis is around 3-4 million meters. Whenever I add more fuel, I just use more getting to orbit around Kerbol since my craft is already like 500 tons. I have more then enough funds and leveled-up facilities to build things, but I started playing KSP around a month ago, so I don't know what my best options are for this. Just to add: In all of my attempts I just burnt prograde until I was on an escape trajectory from Kerbin, then warped to my Kerbol orbit apoapsis, and when I was there, I would burn retrograde as long as I could.
