深蓝航天 Deep Blue Limited – Deep Blue Aerospace Landspace 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…..
LandSpace Zhuque-2 Improved Y7 Launch Successfully At 14:26 Beijing time on September 15, 2026, the Zhuque-2 improved Y7 carrier rocket (ZQ-2E Y7) was successfully launched from the LandSpace liquid oxygen-methane carrier rocket launch pad in the Dongfeng Commercial Aerospace Innovation Test Zone, sending 10 Qianfan Polar Orbit 19 satellites from Shanghai Yuanxin Satellite Technology Co., Ltd. into their predetermined orbits. The flight test mission was a complete success.
The Zhuque-2 E-2 carrier rocket, also known as the Y7, was launched from the Dongfeng Commercial Space Innovation Test Zone at the Jiuquan Satellite Launch Center on September 15, 2026, sending ten satellites of the Qianfan constellation into their predetermined orbits. This marks the first time a privately-owned commercial carrier rocket in China has carried out a batch launch mission for a giant satellite internet constellation, and also signifies that the Zhuque-2E has officially entered a phase of routine, high-density commercial launches.
This mission marks the third consecutive success for Zhuque-2E, following the successful return to flight in May (Y5) and the launch of two satellites, Qianfan DTC01 and China Mobile 02, in June (Y6). From the failure of Y3 in 2025 due to a level-two malfunction, resulting in a nearly year-long absence from the commercial payload market, to gradually restoring launch capabilities after completing technical reset in nine months, the success of Y7 signifies that LandSpace has regained the trust of the commercial market and will usher in an era of large-scale network launches
The modified Zhuque-2 is a two-stage, cryogenic, extended liquid oxygen-methane launch vehicle with a body diameter of 3.35 meters and a maximum fairing diameter of 4.2 meters. It has a payload capacity of 6 tons to low Earth orbit and 4 tons to a 500-kilometer sun-synchronous orbit. The Zhuque-2 series previously achieved the world’s first successful orbital insertion using a liquid oxygen-methane rocket in July 2023. The success of this Y7 mission further validates the rocket’s mass production and delivery capabilities and its engineering maturity.
The Qianfan constellation is a large-scale low-Earth orbit satellite internet constellation planned and deployed by my country. According to the phased network target of 324 satellites by 2026, there is currently a shortfall of 86 satellites. The Zhuque-2E rocket, launched at a high frequency of one launch per month, will significantly alleviate the pressure on the Qianfan constellation’s network deployment schedule, and private rockets will be formally incorporated into the national satellite internet supply chain system
At 14:26 on September 15, 2026, the Zhuque-2 improved Y7 carrier rocket was successfully launched from the Dongfeng Commercial Aerospace Innovation Test Zone, sending the Qianfan Polar Orbit 19 satellites into their predetermined orbits in a “one rocket, ten satellites” manner. This marks the first time that a private commercial aerospace company in my country has undertaken a large-scale satellite internet constellation networking mission, signifying that the private aerospace industry has officially entered a new stage of batch networking.
I. Launch Overview and Mission Core
- Launch details : The Zhuque-2 improved Y7 (ZQ-2E Y7) was launched from the LandSpace liquid oxygen methane launch pad in the Dongfeng Commercial Aerospace Innovation Test Zone at 14:26 Beijing time on September 15
- Payload into orbit : The rocket successfully sent 10 Qianfan Polar Orbit 19 satellites from Shanghai Yuanxin Satellite Technology Co., Ltd. into their predetermined orbits, marking a complete success for the flight test mission.
- Milestone in the series : This mission marks the 9th flight of the Zhuque-2 series carrier rockets and the first time this type of rocket has carried out a large-scale satellite internet constellation networking mission
II. A Historic Breakthrough for Private Aerospace
- This marks the first time a private commercial aerospace company in China has undertaken a large-scale satellite internet constellation networking mission, signifying that private rockets have risen from “substitute players” to “main players.”
- Technical verification : The improved Zhuque-2 rocket, with its two-stage configuration, achieved a launch capacity equivalent to a three-stage rocket. It was the first in the private aerospace sector to achieve an orbital insertion at an altitude of 900 kilometers and to precisely deploy 10 communication satellites in one go.
- Mature capabilities : The mission has completed the entire engineering process of launching multiple satellites with a single rocket, satellite-rocket coordination, batch deployment of satellites, and deorbiting of the rocket’s final stage, while taking into account both networking efficiency and space debris management requirements
III. Rocket Performance and Constellation Construction
- Rocket parameters : The improved Zhuque-2 rocket is 55.9 meters long, has a takeoff mass of 267 tons, a low Earth orbit payload capacity of 6 tons, and a 500-kilometer sun-synchronous orbit payload capacity of 4 tons.
- Qianfan constellation progress : With this launch, the number of Qianfan constellation satellites in orbit has increased to 248, bringing it close to the goal of completing the first phase of global networking with 324 satellites by the end of 2026..
- Routine launch capability : LandSpace has achieved routine commercial launches of the improved Zhuque-2 satellite. This mission was only 27 days after the Zhuque-3 Y2 flight test, demonstrating its high-density launch organization capability
