Perhaps the submission was a bit premature. I'll spend some more time playing and start work on something more complex (not that I seem to have much free time lately - University seems to take up far too much of my time these days).
In retrospect, the shuttle probably wasn't the greatest idea to do. I'm still fairly new to creating curved surfaces in Blockland, and as mentioned before shuttles have been tried before without much success. The satellite was also probably a bad idea, but I just felt that as it was an open shuttle it needed one of those arms, and it had to be doing something.
