Sure. How large is the craft?
Erinamese Cosman Units (Supermassive Manufacturing Centers) come back from around the Sun. They lead what appears to be a supermassive spacecraft. The craft passes the Cosman Units and flies at an incredible speed, flying from Mercury to the asteroid belt in six minutes. The craft slows down, and begins to devour unoccupied asteroids like a vacuum cleaner. They are ground up and refined inside of the ship, and the resources are sent to pickup areas where smaller ships begin to take the materials back to TE on Earth in massive quantities.
This processing train takes up 9% of the ship. The ship has a length of 48 miles, is 7 miles wide, and 5 miles high. The ship contains materials harvested from strip mining projects from all throughout the solar system.
The ship's name: Lünå'i.
(In case you were wondering, I started this project decades ago.)
