After hours of building of a whackjobian-esque 1000 ton rocket, finally got it into orbit, separate orbital stage, approaching space station...closer...closer...closer...activate RCS...uhm...RCS? Symmetry why you put one RCS when I want four? CRASH. If in doubt blame the game. I know failing is half the fun of Kerbal but its the lesser half. http://i.imgur.com/HvW8utr.jpg
