The purpose of this challenge is to create real life rockets/missions that launched or didn't.(Looking at you, Constellation!) It would be nice to have it stock, but it's no matter, I have a list of approved mods below. KW Rocketry TweakScale Kerbal Alarm Clock Kerbal Engineer Outer Planets (for New Horizons, Juno, Cassini-Huygens etc.) I have an Atlas V with new horizons that may be posted on imgur. What will you build? Happy Ship building!
