Speedy Moon Landing
From Kerbal Space Program Wiki
This is a challenge where you have to launch from Kerbin, land on the Mun, plant a flag, and land back at Kerbin in 15 minutes. If you want to go try hard mode, see if you can make it in under 10 minutes. There you are not allowed to use any mods like HyperEdit or MechJeb, and you can not enable any cheats. You are supposed to complete this all by yourself.
