Xia ruofei's requests gave Elon Musk the feeling that they wanted to set up a space transportation company, and that their business was bigger than SpaceX.
They were just short of proposing to buy their Falcon rockets. Otherwise, they would have just acquired SpaceX.
Xia ruofei laughed and said,"Mr. Mask...Don't be impatient ... You can understand that we want to do a space survival experiment. We want to simulate the real environment as much as possible!" Of course, we don't need a complete Dragon Ship, at least it doesn't need a power system, uh ... Communication and control system is not really needed. What we need the most is the cabin of the ship. Of course, this needs a cabin that can operate stably in space, and it needs to be able to provide oxygen continuously. "
If he were to use the Dragon Ship, he would naturally just drag it along the back of the black Phoenix flying ship. There was no need for a propulsion system.
