Compared with the production modules that are divided into different production areas, the maintenance module is a "iron tube" with a length of tens of meters and a diameter of eighteen meters.

The bulkhead on one side can be opened, and the inside is a "big belly" with a diameter of 14 meters, which can accommodate various spacecraft.

A "little guy" like the "Penyue-class" spacecraft with a diameter of 5 meters and a total length of 10 meters can accommodate several ships at the same time, let alone various types of satellites smaller than it.

Close the large cabin door by closing the maintenance module to form a pressurized space. Astronauts can wear light maintenance work clothes to inspect the equipment, which is many times better than wearing heavy outdoor space suits to operate outside the cabin.

At that time, the "Benyue Class" spacecraft can be converted into a space garbage collection ship and a faulty spacecraft towing ship.

The former collects space waste and sends materials to the orbital manufacturing module, while the latter pulls a faulty spacecraft to repair and maintain the module for maintenance.

Behind the "industrial zone" is the track filling station. Groups of spherical fuel tanks are fixed by metal structures, and the combined diameter will exceed 30 meters.

Because the spacecraft currently needs a large number of fuel, the number of spherical fuel tanks is also relatively large, and it is easy to separate them one by one for fear of accidents.

In case a fuel tank leaks, just turn off the channel connecting other fuel tanks, and it is relatively easy to repair.

Because controllable nuclear fusion reactors cannot be used on spacecraft, the second phase of the project still uses solar panels to provide electricity, and they are all concentrated in industrial areas.

Even though practical technology is very advanced, its solar array is still very huge after it is unfolded.

Since the main body of the second phase project is a central axis structure with a length of 300 meters and the widest one is two large wheels with a diameter of 100 meters, the large solar array in the industrial area can reach 400 meters after it is unfolded, and the "wingspan" will instantly exceed the length.

In this way, it looks like some kind of weird bird.

Well, the huge mechanical bird with a length of 300 meters and a wingspan of 400 meters can be seen on the ground!
