If you’re asking about blueprints: The cyclops has three different things to scan, the hull, bridge and engine. The hull and bridge can be found in mushroom forests and I think some other places, and the engine can be found in the mountains and the underwater floating islands (And maybe somewhere else that I don’t know about).
The blueprint for the rocket will be found in Aurora’s captain’s quarters, which you get the code for in the message from Alterra HQ.
