The successful controlled recovery of a launch vehicle's first stage in China represents a pivotal technological and economic milestone for its commercial space industry.
On July 10, 2026, at 12:15 PM, a rocket lifted off from the Hainan Commercial Space Launch Site. Eight minutes later, its first stage descended in a controlled manner from high altitude to a sea-based platform, where it was securely captured by a cross-shaped, high-strength buffer and arresting net system. This event marked China's first successful controlled recovery of a launch vehicle and the world's first net-based recovery of a rocket stage.
Huatai Securities has characterized this event as a "DeepSeek moment" for China's commercial space sector.
In a recent report, the institution stated that just as the emergence of DeepSeek reshaped market valuation logic for the AI industry chain, the successful recovery of the Long March 10B (CZ-10B) signifies a shift in the investment thesis for the commercial space sector—from "technology validation expectations" to "verification of reusability economics." This breakthrough substantially addresses the bottleneck of launch cost for satellite constellation deployment.
With a clear path now open for reducing launch costs, the pace of low-Earth orbit (LEO) constellation deployment, the frequency of commercial rocket launches, orders for satellite payloads and terminals, and the application of space-based data and computing power are all expected to accelerate.
A Landmark Achievement: CZ-10B Sets Two Global Firsts
The technical sophistication of this mission exceeded market expectations. The CZ-10B is a two-stage, tandem-configured rocket with a 5-meter diameter, developed under the leadership of the First Academy of the China Aerospace Science and Technology Corporation (CASC). Its core first stage uses the same configuration and liquid oxygen/kerosene propellant as the CZ-10A's first stage. The core second stage debuted a newly developed high-thrust liquid oxygen/methane engine. With a liftoff thrust of approximately 890 tons and a launch mass of about 760 tons, its reusable configuration offers a low Earth orbit payload capacity of 16 tons.
This mission established two historic records. First, it was China's inaugural successful controlled recovery of a launch vehicle, making the CZ-10B the first Chinese reusable launch vehicle to achieve recovery and the 657th launch of the Long March series. Second, the cross-shaped, high-strength buffer and arresting net recovery system represents a globally pioneering technical approach, an original innovation by China's space program with no existing precedent worldwide.
From a technology validation perspective, this maiden flight successfully completed a full-process, closed-loop verification of a series of core technologies. These included optimized design of the combined configuration, large-thrust force transmission via the tank bottom, propellant management in partitioned tanks, methane self-pressurization, as well as multiple engine restarts, high-altitude ignition, and high-precision navigation and control. According to CASC's official website, the recovered first stage is scheduled for a re-flight before the end of the year.
Net-Based Recovery: A Disruptive Engineering Rationale
Unlike SpaceX's Falcon 9, which uses vertical landing legs, the CZ-10B has chosen a completely different technical path, underpinned by a distinct engineering logic.
As reported, the return phase was divided into four stages: coasting and attitude adjustment, powered deceleration, aerodynamic deceleration, and landing. The most critical landing phase innovatively employed the world's first cross-shaped, high-strength buffer and arresting net system, working in concert with onboard latching mechanisms to capture the rocket body. Chen Muye of CASC stated that the net-based recovery system offers advantages by eliminating landing legs. This simplifies the rocket's structure, reduces its weight, increases payload capacity, and offers strong adaptability to landing point deviations. The system can effectively "enlarge" the capture window through coordinated net movement.
The recovery platform supporting this system, named "Pathfinder," was developed and delivered by the China Academy of Launch Vehicle Technology in November 2025. It measures 144 meters long and 50 meters wide, with a full-load displacement of 25,000 tons.
The CZ-10B also features innovations in separation technology.
Research from Guotai Haitong points out that traditional separation between stages on expendable rockets relies on pyrotechnics, whose shock loads can damage the structure. The CZ-10B employs a "gas-driven push-rod separation scheme," where high-pressure gas drives push-rods to gently separate the second stage from the first. After separation, the rods retract, aiming to leave the first stage in the most ideal, undamaged condition possible for subsequent reuse. Furthermore, the CZ-10B utilizes a "three-horizontal" test and launch mode (horizontal integration, horizontal testing, horizontal transport), which can compress launch preparation time to under 14 days, effectively increasing launch frequency and mission response speed.
The Next Catalyst: Zhuque-3 Yao-2
The success of the CZ-10B is not an endpoint but the starting point for a series of successive catalysts.
On the private rocket front, the Zhuque-3 Yao-2 rocket completed a static fire test at the Dongfeng Commercial Space Innovation Test Zone on June 29. All key pre-launch ground verification work has been finished, and the rocket is now in a ready-to-launch state. It will make another attempt at a vertical landing recovery of its first stage. Zhang Xiaodong, chief designer of the Zhuque-3, previously stated at the 2026 Space Computing Industry Conference that if recovery succeeds, they aim to attempt the first re-flight of a recovered stage in the fourth quarter.
Orient Securities notes that a primary market concern regarding commercial space has been its lengthy industry cycle. The breakthrough in rocket recovery technology, coupled with plans for a re-flight test of the recovered stage by year-end, suggests the node for large-scale reusable launches could arrive earlier than anticipated. Post-reusability, rocket launch frequency is expected to increase significantly, thereby accelerating constellation deployment.
Catalysts on the satellite side are advancing simultaneously. Experimental satellites for China's satellite internet projects continue their validation, while new technologies like high-speed laser communication terminals and 5G NTN are undergoing accelerated evaluation. The deployment and R&D progress for major domestic constellations are also speeding up, potentially making high-frequency launches a norm.
The Space Race Intensifies: Countdown to Securing Spectrum and Orbital Resources
The backdrop to the CZ-10B's successful recovery is a global satellite internet competition that has entered a white-hot phase, where the strategic value of frequency and orbital resources is becoming increasingly prominent.
SpaceX recently formally applied to deploy its third-generation Starlink (Gen3) constellation, with a planned scale of up to 100,000 satellites, positioned as a global AI communication backbone network. In January 2026, SpaceX submitted an even more ambitious "Starmind" space-based AI computing constellation plan to the FCC, with a maximum planned scale of 1 million satellites. Its primary satellite model, the AI1, is designed with an average computing power of 120 kW per satellite.
Facing SpaceX's million-satellite plans, China submitted an application to the International Telecommunication Union (ITU) in December 2025 for an ultra-large-scale satellite constellation plan totaling over 200,000 satellites, covering approximately 14 constellations—a new record for domestic application volume. The ITU operates on a "first-come, first-served" principle for frequency and orbital resources. After filing, applicants have 7 years to launch their first satellite and have it operate normally for 90 days, and 14 years to complete 100% constellation deployment.
This means China must complete its constellation deployment at a faster pace. The successful recovery of the CZ-10B arrives at a critical juncture within this timeframe, effectively breaking through the launch capacity cost bottleneck.
