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…..

At 16:23 on June 9, 2026, at Workstation 96A of the Dongfeng Commercial Aerospace Innovation Test Zone Inner Mongolia China, People’s Republic of China., LandSpace’s Zhuque-2 improved Y6 carrier rocket (ZQ-2E Y6) successfully launched two satellites in a single launch: Qianfan DTC 01 and China Mobile 02. The Qianfan  DTC 01 satellite, developed by the Innovation Academy for Microsatellites of the Chinese Academy of Sciences, will conduct on-orbit verification of key technologies such as direct mobile phone connection services and integrated space-ground networking, providing technical support for the deep integration of satellite communication with 5G/6G. The China Mobile 02 satellite was developed by GalaxySpace (Beijing) Technology Group Co., Ltd.

The Zhuque-2 improved Y6 carrier rocket has a diameter of 3.35 meters and a maximum fairing diameter of 4.2 meters. Its technical specifications and launch/testing procedures largely inherit the mature solutions from the Y5 mission, and it has the capability to reach a low Earth orbit of 6 tons and a solar eclipse at an altitude of 500 kilometers. With a 4-ton payload capacity to orbital orbit, the Y6 rocket is the mainstay of China’s current liquid oxygen-methane medium-lift launch vehicle fleet. It can flexibly be configured to meet diverse mission requirements, such as launching multiple satellites in a

single launch with a traditional configuration, and high-frequency multi-satellite networking of flat-panel satellites. It can also form a combined launch service solution with the Zhuque-3 reusable launch vehicle. This mission, while fully inheriting the mature technologies of previous launches, has completed several engineering improvements

The Qianfan DTC01 satellite is an experimental satellite for Direct to Cell (DTC) communication within the Qianfan constellation, and it is also the first satellite in the constellation to support direct cell communication. Developed by the Innovation Academy for Microsatellites of the Chinese Academy of Sciences, the satellite adopts a flat-panel design. It is used for verifying key technologies such as direct cell communication application services and integrated space-ground networking, providing technical support for the deep integration of satellite communication with 5G/6G.

. Regarding the interstage separation system, the Y6 rocket adopts the same aerodynamic pusher separation scheme as the Zhuque-3 reusable launch vehicle, using a high-pressure gas source to drive the pusher to achieve interstage separation. While maintaining a roughly equivalent overall weight to the original scheme, this scheme reduces the use of pyrotechnics and supports pre-launch unlocking and actuation testing, further improving installation and operational safety, pre-launch detectability, supply chain self-control, and flight reliability.

In terms of structural manufacturing, the Y6 rocket’s second-stage engine frame adopts a 3D-printed integrated structure. The structure adopts a hollow truncated cone configuration and a Y-shaped main beam design to achieve efficient transmission of engine thrust. While improving the overall structural rigidity and load-bearing capacity, it also reduces weight and cost, and effectively shortens the manufacturing and assembly cycle. This reflects the model’s continuous exploration in the direction of upgrade design schemes and advanced manufacturing processes.

In addition, the adjustment controller has been replaced with a self-developed product, further enhancing the degree of independent control of key core products. The second-stage engine’s throttling condition was reduced to 50%, effectively lowering the overload level in the later stages of second-stage flight and providing a more stable flight environment for precision payloads.

Just 26 days after the Y5 mission, the Zhuque-2 improved Y6 carrier rocket entered the launch phase, demonstrating LandSpace’s continuously improving batch delivery and high-density launch capabilities.

⚙️ Technological Breakthrough of the 20-Ton “Capacity Champion”

• Powertrain :
  • It uses liquid oxygen and kerosene propellant . The first stage is equipped with nine YF-102R engines with a thrust of 100 tons each (90 tons at sea level, supporting variable thrust at depths of 50% to 105%), and the second stage is equipped with one YF-102RV vacuum engine (710 kN vacuum thrust), with a takeoff thrust of 800 tons.
  • By integrating nine engines into a large-diameter common-bottom tank and an integrated tail section design , the rocket body achieves systematic “weight reduction and slimming,” thereby improving carrying efficiency.
• Intelligent control :
  • Equipped with dual flight control computer systems (one for primary and one for secondary flight control), it has fault diagnosis and reconfiguration capabilities, and can monitor the status of nine engines in milliseconds and automatically “coordinate and compensate”
  • For the first time, Time-Sensitive Networking (TSN) technology was applied to achieve microsecond-level synchronous transmission of more than 8,000 parameters across the entire rocket.

• Recycling Design :
  • Although the rocket was not actually recovered during its maiden flight, it has been equipped with four grid fins, four landing legs, and an attitude control system , which provides a foundation for technical verification in subsequent vertical recovery tests

🏭 “Archery range integration” creates a closed business loop

• Self-developed launch pad : The mission utilizes China’s first self-built test and development pad for commercial rockets , capable of supporting the launch of 1,000-ton thrust rockets and achieving compatibility and rapid recovery capability with multiple propellants such as liquid oxygen and kerosene
• Low-cost strategy : Innovative application of mature products such as automotive-grade components and industrial-grade flexible cable networks reduces the weight of cable networks by 30% to 40% , significantly reducing manufacturing costs.3140

🔮 Reusable technology verification and follow-up plans

• Step-by-step iterative path : The maiden flight focuses on verifying the reliability of orbit insertion. Subsequently, a vertical recovery test of the first stage will be carried out at an opportune time, with a target of ≥10 recovery and reuse times and a near-ground carrying capacity of approximately 12 tons in the recovery mode.
• Market positioning : Targeting China’s low-Earth orbit constellation networking needs (such as the “China Star Network” plan of 12,000 satellites), it supports large-scale constellation deployment with high-frequency and low-cost launches , and the cost per launch is expected to be more than 40% lower than that of traditional rockets.

The successful maiden flight marks China, People’s republic of China  entry into the field of heavy-lift launch vehicles for commercial rockets. Subsequent breakthroughs in recovery technology and routine launch capabilities will become key variables in breaking the bottleneck of “many satellites but few rockets” and reshaping the global commercial launch landscape…
