Hello there! I've been playing the demo for a few days now and just recently put Jeb on a decent orbit around Kerbal. I had an attempt at landing on Mun but I messed it up by pressing the space bar accidentally and jettisoning my booster rocket/landing gear/RCS fuel/RCS thrusters so poor Jeb was stuck on an orbit all by himself which he couldn't escape from... Anyway, I'm looking forward to getting the full game soon and expanding my explorations to other planets! Hopefully within a year or so of casual playing I'll have a decent collection of space stations and settlements on land. Cheers!
