The Nostromo is a heavy towing ship used to pull mobile refineries between distant mines and Earth, a journey that takes many months. It is somewhere in the neighborhood of 1000 feet long, and the refineries pulled are several miles square.
I have made my model as small as I felt I could while preserving the essential details, because I plan to build the refinery it pulls at this scale as well.
About this creation
The Nostromo is a massive ship. At this scale, the 1 x 1 cone on the front represents the bridge area. You can also see the forward lift engines and the braking engines in this picture.
The three massive main engines and 4 smaller drive engines on the back.
I have been having something of a Lego Alien 'thing' of my own going on recently and was planning on trying my hand at a micro-scale Nostromo but really, after this, there is little point trying - I am not going to come up with a better micro-design that this; this is pretty much perfect!
I hate to tell you this, Joe, but this isn't the shuttle; the entire Nostromo (detached from the refinery that it was towing) did land on the planet's surface. The shuttle is much smaller and docked with the Nostromo; it doesn't have nearly as much detail as this ship.
