In a significant boost to China’s rapidly expanding commercial space sector, Beijing-based launch startup Astronstone has secured $29 million in fresh funding to accelerate the development of its reusable AS-1 rocket. The heavy-lift vehicle notably features a SpaceX-style “chopstick” recovery system designed to catch the booster mid-air. The “Pre-A+” funding round will finance final assembly, testing, and production capacity expansion ahead of a targeted debut flight in the first quarter of 2027.
Shifting Paradigms in Orbital Access
The global aerospace industry is currently witnessing a massive shift toward fully reusable launch vehicles. In China, this transition is accelerating rapidly across both state-owned enterprises and agile commercial startups. The central government heavily supports this push, driven by the urgent need to deploy nascent national and commercial communications megaconstellations that require high-cadence, low-cost orbital access.
Astronstone represents a newer wave of Chinese space startups bypassing the traditional route of developing smaller, solid-propellant rockets first. Instead, these ambitious firms are moving directly toward large-scale, cutting-edge architectures modeled heavily on Starship-like designs. Fellow early-stage entrants like Nayuta Space and Cosmoleap are also pursuing similar large, reusable architectures, intensifying domestic competition.
Financial Backing and Strategic Growth
The $29 million funding round was co-led by GL Ventures—the venture capital arm of Hillhouse Capital—and Xingxiang Capital, an entity affiliated with the Hunan provincial government. Additional participation came from Minghui Zhiyuan, Qiancheng Capital, Tuofeng Capital, and Zhisheng Ruiying.
This diverse investor syndicate highlights a broader pattern in China’s commercial launch sector: the strategic blending of financial, state, and industrial capital to de-risk highly capital-intensive aerospace projects. Since its founding two years ago, Astronstone has now raised nearly 500 million yuan ($72 million) across four funding rounds.
The company plans to use the capital injection to expand its workforce. As of March 2026, Astronstone employs 170 people, with research and development personnel accounting for more than 70 percent of the staff. The startup aims to grow its team to 300 employees by the end of the year.
Technical Specifications and Market Strategy
The AS-1 rocket is designed as a two-stage, stainless steel launch vehicle powered by liquid oxygen and methane (methalox) engines. Measuring approximately 70 meters in length and 4.2 meters in diameter, the vehicle boasts impressive payload specifications. Astronstone claims the AS-1 will be capable of delivering 15,700 kilograms to low Earth orbit (LEO) in an expendable configuration, and 10,000 kilograms when the first stage is recovered.
The choice of methalox is particularly noteworthy. Methalox burns cleaner than traditional rocket-grade kerosene, minimizing soot buildup in the engines and drastically reducing the refurbishment time required between flights. This chemical advantage is critical for achieving rapid reusability.
Astronstone is targeting an aggressive price point to disrupt the commercial satellite launch market. The company aims to provide launch services at approximately 20,000 yuan ($2,900) per kilogram, a highly competitive rate designed to attract megaconstellation operators.
Hardware Progress and Investor Confidence
Astronstone has already demonstrated tangible progress on its hardware and infrastructure. In December 2025, the company successfully completed a second-stage static fire test campaign. Furthermore, it claims to have executed China’s first full-scale ground test of a 100-ton-class “chopstick” capture arm. This complex mechanical system eliminates the need for heavy landing legs on the rocket itself, thereby increasing the vehicle’s overall payload capacity.
The startup is simultaneously building a robust industrial footprint to support its ambitious 2027 launch target. This includes a dedicated research and development center in Beijing, a primary test base in Hebei province, and a partially operational production and assembly facility in Hunan province.
Investors are expressing strong confidence in Astronstone’s specific technological pathway. Private equity firm Qiancheng Capital stated that the company’s stainless steel, methalox, and rapid-reuse approach is essential for surviving the hyper-competitive launch market. The firm highlighted the future potential of space-based solar power and space computing infrastructure, noting that ultra-low-cost, high-capacity rocket transportation is a strict prerequisite for these advanced concepts.
A Crowded and Competitive Landscape
The broader Chinese aerospace ecosystem is gearing up for a flurry of reusable rocket milestones. State-backed entities are preparing for the debut launches of the reusable Long March 10B and Long March 12B in the coming months. Additionally, the Long March 10A—designed for recovery using a drone ship and wire system—could launch later this year, carrying the first orbital test of China’s new Mengzhou crew spacecraft.
On the commercial front, established players are also advancing their reusable programs. Landspace is expected to execute a second launch and recovery attempt with its Zhuque-3 rocket as soon as April. Meanwhile, Space Pioneer and CAS Space are working toward their own debut launches in the near future.
Deep Blue Nebula is preparing for a critical suborbital launch and recovery test of its Nebula-1 vehicle from new maritime launch infrastructure at Lianli island, off the coast of Haiyang. The company is simultaneously developing propulsion systems for the larger Nebula-2.
As Astronstone works toward its critical first-stage static fire tests scheduled for 2026, the company’s progress will serve as a bellwether for China’s next-generation launch startups. The successful validation of its chopstick recovery technology could drastically reduce turnaround times and launch costs, fundamentally altering the economics of Chinese spaceflight. Industry observers should closely monitor the upcoming slate of commercial recovery tests, as these flights will dictate the pace at which China can field a fully operational, reusable launch fleet.
