Targeting the ultimate solution for commercial launch vehicles
"Chopsticks" Catch & Recovery System
01 RECOVERY

"Chopsticks" Catch & Recovery System

In-situ Recovery, In-situ Reuse

Standing 100 meters tall with a 16-meter arm span, the "Chopsticks" Capture and Recovery System covers an area equivalent to half a football field.

During recovery, integrated multi-sensor perception and real-time decision control enable dynamic mid-air capture. This overcomes the rigid constraints of traditional vertical landing on touchdown precision, fuel margins, and structural endurance, allowing all-weather in-situ recovery and rapid reuse in complex environments.

With cross-disciplinary expertise in aerospace and robotics, Astronstone has fully mastered key technologies in capture arm design, computer vision fusion, and real-time structural inspection for stainless steel rockets. In December 2025, Astronstone completed China's first ground validation of a 100-ton class capture arm prototype, redefining the boundaries of rocket recovery through engineering excellence.

Stainless steel launch vehicle

Low Cost, High Efficiency

Custom 30X stainless steel airframes reduce manufacturing costs to one-tenth of aluminum alloys while exponentially boosting production efficiency. With lead times as short as one month, the full lifecycle from design to rollout is no longer measured in years.

As a pioneer in stainless steel rocket airframes in China, AstronsTone built an independent supply chain ecosystem from the ground up. We have mastered end-to-end capabilities spanning raw material production, advanced manufacturing processes, and specialized tooling. Driven by an open collaboration model, we will share our stainless steel airframe manufacturing capacity with industry partners.

Methalox Propulsion

The Ideal Propulsion for Next-Gen Reusable Rockets

Methalox engines feature multi-restart capability and wide-range thrust throttling, ensuring precise control from liftoff to touchdown. With clean combustion products and low maintenance demands, Methalox is inherently suited for high-frequency reuse, serving as the ultimate propulsion for next-generation reusable rockets.
