【Abstract】 In 2018, the numbers of world orbital launches has been to over 100 for the first time from the nineties of the 20 th century. The space contries have pushed out the new space policy and defined the future space development direction, with the deep-space exploration being the main direction. The space countries continued to advance the super-heavy launch vehicles, the new heavy and medium-sized launch vehicles and rapidly-launch small launch vehicles’ development, technology verification in launch vehicles’ reusability. This paper mainly reviews the orbital launches of launch vehicle, the development progress of the new launch vehicles, the deployment of foreign countries and the significant events of this field in 2018. At the end of the thesis, it makes a forecast on the future development in 2019.更多还原
