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！
往返于地球与太空之间的“太空班车”
2017年，SpaceX宣布了一项太空旅游计划，用一枚猎鹰火箭将载有两名乘客的“龙二”飞船送往月球轨道并返回地球。尽管到目前为止这一切都还没有发生，但很多太空爱好者已经跃跃欲试。
“在这些创新的企业眼里，太空班车就是交通运输工具。”中国宇航学会副理事长兼秘书长王一然作为报告人出席了本届大会的主题论坛之一——未来交通论坛。在他看来，“人类不可能永远停留在地球上，总要走出地球空间。这个目标在一步步接近，我们期待能在天上看地球。”看来，随着航天技术不断成熟，除了海、陆、空这些传统的交通运输领域，开发出往返于地球与太空之间的“太空班车”也成为可能。
我国也在开展相关的商业性航天技术开发研究。例如，中国航天科工集团有限公司正在研发水平起降、可重复使用的新一代天地往返飞行器，并且已经于2017年完成了发动机等多项关键技术地面试验。
而中国航天科技集团有限公司也瞄准了天地往返重复使用飞行器，开展了组合发动机的研究和地面集成试验，一旦投入使用，将大大提高进出空间的便捷性，面向大众的太空旅游也许将成为可能。
与此同时，航天技术“外溢”也在改变着交通运输。例如，交通运输领域是北斗卫星导航系统最重要的应用领域之一，为车辆提供着稳定可靠的定位和导航。据王一然介绍，目前我国已经有600万辆营运车辆接入北斗导航系统，很大程度上提高了车辆的运行安全。
“未来，人们既能拥有更舒适、快捷、安全的交通运输，还能体验带有冒险精神的太空交通工具。”王一然对未来的交通运输充满憧憬。

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.
