What happens when you conquer a city where a spaceship is under construction?

What happens when you conquer a city where a spaceship is under construction? Can the conquered civilization continue construction in its new capital? Does the conquered civilization retain its already-constructed modules? Do you get to capture the already-constructed modules as your own?

Note : I am talking about modules that have already been added to the spaceship, not ones who are still walking around as units.

The conquered civilization can continue constructing the spaceship in its new capital - an appropriate spaceship model will actually appear in the new capital as well.

The conquered civilization retains all its already-constructed modules, and does not need to build them again.

The conquering civilization does not get access to any of the constructed modules.
