So my plan was to blow a hole into the planet and start from the hole. When building with the build block on a planet you will notice that the blocks placed do not load right away, well to solve this just move inside the planet (shift+a,w,s,d,e, or q) while in build mode and move back into open space. this should show the new blocks. Anyhow this is what ive finished so far. =)
