Space launch set a new record, setting a record for China's shortest rocket launch interval

On November 13, China launched two rockets in a row, with a launch interval of only 175 minutes, setting a record for the shortest launch interval in China.

At 11:40 Beijing time on November 13, China successfully put the "jilin-1" Gaogao 02A satellite into the predetermined orbit with the kuaizhou-1 jiayao-11 carrier rocket at the Jiuquan Satellite Launch Center, 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 aerospace Sanjiang group of China Aerospace Science and Industry Corporation. The rocket has the carrying capacity of 200kg / 700km solar synchronous circular orbit and has the characteristics of high reliability, high orbit entry accuracy and low cost. This is the second launch mission of the kuaizhou-1a Solid Launch Vehicle in the year, the first time it has launched many times in a year, and the fourth time it has completed commercial launch.

Good things come in pairs. The wonderful performance of China's aerospace on that day has just begun.

175 minutes later, China launched five satellites with one arrow with a long March 6 carrier rocket at the Taiyuan Satellite Launch Center at 1435, and accurately put five Ningxia No. 1 satellites (also known as zhongzi satellite) into the predetermined orbit.

This is the first low angle launch of the Long March 6 carrier rocket and the third flight of the Long March 6 carrier rocket. According to the mission requirements, the rocket has made a series of technical upgrades, including take-off roll, lateral guidance, new composite double-layer wall mounted launcher and so on.

Experts pointed out that in the same day, the short interval between the relay launch of the kuaizhou-1a solid launch vehicle and the long march-6 launch vehicle has put great pressure on each link, especially satellite measurement and control, but it is not easy for Chinese aerospace workers to successfully complete the task.

By the end of 2019, China's Aerospace will usher in high-density launch again. It is expected that by the end of this year, China will carry out many more space launch missions, and the number of launches in the whole year will exceed 30.
