The "Chongqing Star of Two Rivers" rocket is the first private aerospace technology company in ChinazerOne Space Developed commercial rockets.The reason for naming "Chongqing Star of Two Rivers" isLiangjiang New Area, ChongqingIt is the "place of hope" that carries Zero One Space.[1]
At 7:33:31 on May 17, 2018, China's first privately developed commercial rocket, the OS-X "Chongqing Star of Two Rivers", was launched from a base in Alashan League, Inner Mongolia, China.[2-3]
On September 7, 2018, Zero One SpaceJiuquan Satellite Launch CenterIt launched its second commercial suborbital rocket, the OS-X1 rocket and the "Chongqing Star of Two Rivers".[4]At about 17:39 on March 27, 2019, the "Chongqing Star of Two Rivers" OS-M carrier rocket was launched atChina Jiuquan Satellite Launch CenterIgnition.The rocket appeared abnormal dozens of seconds after lift off, leaving a complex trace in the sky and disappearing out of people's sight. The launch mission failed.[5]
On May 17, 2018, the first flight of "Chongqing Star of Two Rivers"
The arrow of "Chongqing Star of Two Rivers" is 9 meters long and has a total weight of 7200 kg. The main body of the arrow is painted with two parts of the curve pattern of "Chongqing Star of Two Rivers" characters and surrounding characters.[3]
The two curve patterns represent the Yangtze River and the Jialing River, that is, the two rivers in ChongqingLiangjiang New Area, ChongqingThe color of the logo makes people feel that this rocket is tailored for Chongqing Liangjiang New Area.[6]

Chongqing Star of Two Rivers
On December 22, 2017, Zero One Space X Seriesrocket engineThe combined commissioning of the whole machine has been successfully completed.The engine was shut down after 35 seconds of operation, and the test was a complete success, which was also the first commercial engine in ChinaSolid rocket motor。
On March 31, 2018,Chongqing Daily It is reported that China's first private rocket will fly in June 2018, and the rocket will be named "Chongqing Star of Two Rivers".[1]
On April 11, 2018, the "Star of the Two Rivers" rocket carried out its first general assembly training in Beijing, which mainly included three processes: indoor general assembly, indoor to outdoor transfer and off-site rocket erection.The successful completion of the final assembly training marked that the first private self-developed commercial rocket in China, the "Star of Two Rivers", was closer to its first flight.[2]
At 7:33:31 on May 17, 2018, the private commercial rocket OS-X "Chongqing Liangjiang Star" was launched from a base in Alashan League, Inner Mongolia, China.[2-3]
At 12:10 on September 7, 2018,Jiuquan Satellite Launch CenterSuccessfully organized and launched the "Chongqing Star of Two Rivers" (OS-X1) commercial suborbital rocket.[7]
First flight of OS-M carrier rocket
At 17:39 on March 27, the zero one space OS-M carrier rocket ignited and launched. The first stage flight of the rocket was normal, and the separation of the first and second stages was normal.After the first and second stage separation, the rocket attitude was unstable, and the launch was unsuccessful. The launch mission was not completed, and debris at all levels fell in the safety zone.In the first time, Zero One Space organized many experts to study the rocketflight testAnalyze the data and locate the fault.After data interpretation and analysis, it is preliminarily determined that the reason is that the rocket's rate gyro failed 45.68 seconds after the rocket flew, resulting in the rocket's attitude divergence.[8]
At 17:05:05 p.m. on February 5, 2021,zerOne Space The new intelligent suborbital rocket OS-X6B&"Chongqing · Liangjiang Star" was successfully launched from a launch site in northwest China under the remote command of the company's Chongqing Liangjiang TT&C Command Center. The test load was successfully separated and the whole flight was normal. It completed two major test tasks, including the verification of key technologies of Linglong series carrier rockets, a new space load and its equivalent flight test key technologies,A large number of real flight environment data were obtained, and the launch was a complete success.[9-10]

Chongqing Star of Two Rivers
Compared with other industries, the aerospace industry is characterized by high technology, high cost and high risk.At the same time, the aerospace industry is closely related to military and national security.Often, countries develop aerospace industry based on the need of strategic security, regardless of cost.This leads to the high cost of existing aerospace products. The commissioning and application of private rockets will greatly reduce the cost of the aerospace industry, shorten the R&D cycle, and promote the vigorous development of China's aerospace industry.
The OS-X series rockets independently developed by Chongqing OneSpace adopt their own researchSolid rocket motorAs power, the engine thrust reaches 350KN, which can achieve a flight speed of Mach 0~20 for the customer load.
The rocket can be flexibly configured with gas rudder, air rudder, attitude control power and other control mechanisms, and has strong control ability. It can be customized according to user needs to meetflight testAll kinds of complex flight trajectories required.[6]
Chongqing Star of Two Rivers
"Relative toLiquid rocket engineAs far as solid rocket motors are concerned, they have the advantages of easy realization of high thrust, high reliability, simple launch operation, convenient use and maintenance, etc. "Hu Jianxin analyzed that because of the use of solid rocket motors as power units, OS-X series rockets have the characteristics of overall storage, simple operation, low launch cost, and short launch cycle. Its biggest advantage is "fast, convenient, and flexible", which can realize the rapid networking and network supplementation of satellites, and can well meet the emergency launch needs of natural disasters, emergencies, and so on.
The core electrical product of "Chongqing Star of Two Rivers" adopts an integrated integrated controller, which takes the lead in realizing the integration, miniaturization and lightweight of the rocket control and measurement system.The weight of the integrated control computer is only 1.8kg, which is one tenth of that of previous products.
