Doha. As the centre of the Federation, its intergalactic spaceport was also the largest and most luxurious of all the planets in the Federation. The spaceport was built in the outer space of the planet; the room inside it about the size of a city on the planet. Meanwhile, the staff of the spaceport all lived in the spaceport city. Other than a difference in gravity, everything else felt no different from being on the planet itself.
Connecting the spaceport and the planet was a specialised rocket car, while the heart of the spaceport itself was a special platform for it. It would receive the specialised rocket cars from various cities from all over. It could be said that the liveliest and most hectic place in the entire spaceport with the most people was right here. Even during normal periods, it would serve several hundred thousand people every day.
