Chinese commercial space firm Light Year Explorer has manufactured a rocket payload fairing featuring a wooden outer skin, aiming to lower production costs and speed up manufacturing for frequent launch vehicles.
The Jiangsu-based aerospace company constructed the protective nose cone shell using low-density plywood formed into a smooth aerodynamic curve. An internal metal framework supports the structure to bear launch loads. The resulting 4.2-meter-wide product is engineered to protect commercial payloads and multiple satellite deployments during ascent through Earth’s atmosphere.
Cutting Costs With Wood
Traditional payload fairings are typically manufactured from aluminum alloys or advanced composite materials, which involve lengthy production cycles and high expenses. Light Year Explorer designed its wooden alternative to cut those expenses while maintaining structural integrity.

This configuration matches traditional composite fairings in key performance areas such as weight, structural rigidity, radio wave transparency and noise reduction, while reducing production costs and shortening manufacturing time markedly,
the company stated in a social media post.
Stainless-steel tanks, wooden fairings, and corrugated cylindrical-conical sections together account for about 60% of a rocket’s mass according to company estimates, driving the firm’s focus on inexpensive structural components.
Testing Wooden Rocket Components
Before delivering the components to customers, Light Year Explorer must complete testing and validation procedures to finalize the design. The development arrives as Chinese aerospace manufacturers pursue lower-cost technologies to support expanding satellite constellations and reusable rocket programs.
The exploration of wood in space applications includes projects like LignoSat, a wooden satellite created by researchers at Kyoto University that was deployed into orbit from the International Space Station in 2024.
