Two rockets flew into the sky one after another, and the two rockets were launched one after another

At 11:40 on November 13, the kuaizhou-1 jiayao-11 carrier rocket named "kuaizhou our space" was launched from Jiuquan Satellite Launch Center with "jilin-1" Gaogao 02A satellite. The satellite successfully entered the predetermined orbit and the mission was a complete success.

The kuaizhou-1a solid launch vehicle is developed by the aerospace science and industry Rocket Technology Co., Ltd. affiliated to the Fourth Academy of China Aerospace Science and industry group. The rocket adopts an international common interface, mainly provides launch services for low orbit small satellites, has a 200 kg / 700 km solar synchronous circular orbit launch capacity, and has the characteristics of high orbit entry accuracy, short preparation cycle and low launch cost. This is the second launch mission of the kuaizhou-1a Solid Launch Vehicle this year. Previously, it successfully completed three commercial launches in January 2017, September 2018 and August 2019 respectively.

Gaogao 02A satellite of "Jilin No. 1" is a new optical remote sensing satellite independently developed by Changguang Satellite Technology Co., Ltd. The satellite fully inherits the mature stand-alone and technical basis of "Jilin No. 1" satellite, and has the characteristics of high resolution, large width and high-speed data transmission. After the satellite goes into orbit, it will be networked with the 13 previously launched "Jilin No. 1" satellites to provide richer remote sensing data and products and services for users in agriculture, forestry, resources, environment and other industries. This mission is the seventh launch of the "jilin-1" satellite project.

The kuaizhou-1 jiayao-11 carrier rocket launched this time was named by the 'our space' new media center. The center is committed to condensing the soul of aerospace, praising astronauts, talking about aerospace affairs, transmitting Aerospace feelings, building a solid Aerospace dream, and managing the 'our space' new media matrix of operation and maintenance, which has become an important information source of China's aerospace.

Good things come in pairs. The performance of China's aerospace day is not over. At 1435, China successfully launched Ningxia No. 1 satellite (also known as zhongzi satellite) with a long March 6 carrier rocket in Taiyuan Satellite Launch Center.

The five satellites of Ningxia No. 1 are commercial aerospace projects independently invested and constructed by Ningxia Jinsi Information Technology Co., Ltd. Satellites are mainly used in remote sensing and other fields.

Ningxia No. 1 satellite and long march No. 6 carrier rocket were developed by China Aerospace Science and Technology Group Dongfanghong Satellite Co., Ltd. and Shanghai Aerospace Technology Research Institute respectively.

This mission is the 318th space flight of the long march series of launch vehicles.

It is understood that the launch time of the two rockets is only 175 minutes apart, setting a record for the shortest launch interval in China.
