Those ships in particular look really well suited to construction in Lego.Now that I give it some thought, this is another advantage of Space Engineers. I should be able to easily replicate any of my ships using real-world LEGO blocks!!!
Granted, I'd probably need a special "NASA" LEGO set for things like thrusters..
The glazing at the front might be a bit tricky / expensive but they may work well in a smaller, non minifig scale.
