After you research the Rocket Silo techonology, you will be able to craft the Silo Excavation site. Place it where you want to start the excavation process (requires energy - A LOT!):
To build a Rocket Silo, you will have to work on 6 building stages:
Stage 1: excavating : remove enough stone from the site;
Stage 2: Add concrete, stone brick, steel, and iron stick;
Stage 3: deep excavating: remove more stone from the site;
Stage 4: Add concrete, steel, pipe and pipe to ground;
Stage 5: Add concrete, steel, pipe, iron-plate, copper cable, green and red wires;
Stage 6: Add refined concrete, electric engines, processing units, radars, advanced and electronic circuits
After that, the silo will be ready and placed.
-Protect your construction site: aliens may not like the pollution and noises it causes.
-Do NOT remove a silo excavation site. If you do, all progress and expensive materials used will be lost, and the excavation will start again. There is a mod option do make the construction stages non-removable. This prevent losing materials.
Now compatible with Space Exploration and bobs/angels mods: their materials will be required.
