随着科技发展，买车的人越来越多，交通越来越堵，人们想到了造飞行汽车，无人驾驶的概念飞行汽车, 比高铁还要快, 未来空中限速吗？相信未来空中会有专业的空中交管，具体限速多少根据不同线路来定速度！
With the development of science and technology, more and more people buy cars, traffic is getting blocked, people think of flying cars, unmanned concept flying cars, faster than the high-speed rail, the future air speed limit? I believe that there will be professional air traffic control in the future, and the speed limit will be determined according to different speeds!
A "space shuttle" between Earth and space
In 2017, SpaceX announced a space travel program that used a Falcon rocket to send a two-passenger "Dragon II" spacecraft to the lunar orbit and return to Earth. Although all this has not happened so far, many space enthusiasts are already eager to try.
"In the eyes of these innovative companies, the space shuttle is a means of transportation." Wang Yiran, vice chairman and secretary general of the China Aerospace Society, attended the conference as one of the theme forums of the conference - the Future Transportation Forum. In his view, "Humans cannot stay on the earth forever, and always have to go out of the earth space. This goal is approaching step by step, and we are looking forward to seeing the earth in the sky." It seems that as space technology continues to mature, in addition to the sea, In the traditional transportation field of land and air, it is also possible to develop a "space shuttle" between Earth and space.
China is also conducting research on related commercial aerospace technology development. For example, China Aerospace Science and Industry Corporation is developing a new generation of world-class round-trip aircraft that can take off and land, and has completed several key technical ground tests such as engines in 2017.
China Aerospace Science and Technology Group Co., Ltd. is also aiming at the re-use of the aircraft to the world, and has carried out research on combined engines and ground integration tests. Once put into use, it will greatly improve the convenience of access to space, and space tourism for the general public may become possible.
At the same time, aerospace technology "sinking" is also changing transportation. For example, the transportation field is one of the most important application areas of the Beidou satellite navigation system, providing stable and reliable positioning and navigation for vehicles. According to Wang Yiran, at present, there are 6 million operating vehicles in China that are connected to the Beidou navigation system, which greatly improves the operational safety of the vehicles.
“In the future, people will have more comfortable, fast and safe transportation, and experience spacecraft with adventurous spirit.” Wang Yiran is full of embarrassment for future transportation.
