深蓝航天 Deep Blue Limited – Deep Blue Aerospace One of sixty Chinese private space Carrier Rocket Companies in China-People’s Republic of China… As many of sixty plus Private Rocket Deep Blue Aerospace Co., Ltd. was established in 2017. The company is mainly a high-tech aerospace enterprise that focuses on the direction of liquid recovery and reusable launch vehicles and provides users with commercial launch services. Deep Blue Aerospace Co., Ltd. is headquartered in Nantong City, Jiangsu Province. At the same time, the company has rocket general and liquid engine R&D centers in Yizhuang, Beijing and Xi’an, Shaanxi, respectively, and a rocket power system test base in Tongchuan, Shaanxi…..

At 10:00 Beijing time on November 27, 2024, at the 96A workstation in the Dongfeng Commercial Space Innovation Test Area of the Jiuquan Satellite Launch Center, inner Mongolia, China, People’s Republic of China., the “Zhuque-2” improved (Yao-1) carrier rocket carrying the Guangchuan 01 and 02 test satellites ignited and took off. About 8 minutes and 25 seconds later, the satellite and rocket separated, sending the satellite into a low-Earth orbit with a perigee of 300 kilometers, an apogee of 500 kilometers, and an inclination of 50 degrees.












Guangchuan 01 and 02 are low-orbit communication test satellites used to test and verify low-Earth orbit communication satellite constellation technology.

The improved version of the Zhuque-2 (ZQ-2E) launch vehicle uses the basic first stage and a deeply improved second stage. The improvements of the second stage are mainly reflected in the structural system and power system. In terms of the structural system, the improved second stage adopts a single-layer common bottom tank and tunnel delivery pipe scheme, which simplifies the structure and reduces the stage height and rocket body mass.

In terms of the power system, the second-stage main engine was replaced by the vacuum-type “Tian Que-12” (TQ-12) with the vacuum-type “Tian Que-15A” (TQ-15A) liquid oxygen-methane engine. The latter has significantly improved thrust and specific impulse and has the ability to start three times. At the same time, the second-stage “Tian Que-11” (TQ-11) swimming engine was removed and replaced by the “Yun Que 10” (YQ-10) auxiliary power system. “Yun Que 10” is used for the second-stage precise attitude adjustment, terminal speed correction, propellant sinking, orbit change, and deorbit.

The improved version of the “Zhuque-2” (ZQ-2E) rocket is 47.3 meters high, with a first and second stage and fairing diameter of 3.35 meters, a takeoff mass of 219 tons, a takeoff thrust of 282 tons, and a 500-kilometer sun-synchronous orbit (SSO) capacity of 4 tons. Compared with the basic version of the “Zhuque-2”, the improved version has a height reduction of 2.2 meters, a takeoff mass reduction of 1 ton, a takeoff thrust increase of 14 tons, and a 500-kilometer sun-synchronous orbit capacity increase of 2.5 tons.

The improved version of the Zhuque-2 rocket has created many firsts in China’s aerospace industry. This rocket is China’s first dual-cryogenic liquid carrier rocket that uses full supercooling and filling, the first time in China to use a dual-cryogenic single-layer common bottom tank for a liquid carrier rocket, and the first time in China that the Tianque-15A engine uses large-size, high-precision niobium alloy nozzle processing and manufacturing technology for large-scale engines. In addition, this mission is the first time that a Chinese carrier rocket has used a probability-based high-wind area flight load calculation method, a stage separation cancellation forward rocket plan, and a rocket glide stage propellant intermittent bottoming plan.
Since its maiden flight on December 14, 2022, Beijing time, the “Zhuque-2” series of rockets has carried out four launches in less than two years, achieving three consecutive victories since the basic Yao-2 mission. In the process, the “Zhuque-2” rocket became the world’s first liquid oxygen-methane rocket to achieve an orbital launch, the first to successfully launch a payload, the first to launch continuously and the first to achieve three consecutive launch victories. The improved Yao-1 of the “Zhuque-2” is the first rocket of the new batch of the “Zhuque-2” series, and since then, the series of rockets has entered a new stage of normalized commercial launches.

This launch mission is the first launch of the Zhuque-2 carrier rocket in 2024, the 19th launch of the Jiuquan Launch Center, the 58th launch in China and the 224th launch in the world. At the same time, this launch is also the first launch of a private commercial liquid rocket in China in 2024.
