SpaceX CEO Elon Musk announced through his Twitter account that he would set up a space airport for the starship, a large rocket and spacecraft.
He plans to use the starship, a large spacecraft targeting the Moon and Mars, as a regular flight connecting major cities on Earth. However, as the launch of the rocket generates a very loud noise, in November 2019, it was revealed that it is necessary to take off and land at a sea of 32 km in order to achieve an acceptable level of noise from flying rockets connecting the entire earth. To install a space airport on the sea also means to secure safety in case of emergency.
Then, how do we set up a space airport on the sea? He replied that it was quite close to the question of what seems like a hyperloop connection of offshore oil platforms on land. The SpaceX is different in size, but it already has sea landing experience in recovering the Falcon 9 booster. It also started hiring technicians to engage in maritime work, as if sincerely thinking about the construction of a marine space airport.
Elon Musk said the starship test flight for intercity operation may be in the next two to three years. However, considering that the Crew Dragon is still in its first flight to the International Space Station with two astronauts on board, and the starship development is also in the middle, it is a story when two to three years later is quite smooth. It would be better to put it. Related information can be found here .
