China Unveils Reusable Five‑Meter Composite Propulsion Module for Long March 10

Context Composites reduce structural weight, allowing rockets to carry more payload or fuel for reentry burns. China’s space program has been accelerating reusable‑rocket development to narrow the gap with leaders like SpaceX. The module was designed by the China Aerospace and Technology Corporation at its First Academy, marking the nation’s largest integrated composite aerospace structure to date.

Key Facts The propulsion module contains over 60 % composite material, so it is not fully composite but represents a major step toward that goal. A prototype Long March 10 first‑stage booster launched successfully a few weeks ago, executed a controlled descent, and splashed down in the South China Sea. Both achievements were announced in an April 11 press release from the state contractor.

What It Means The new module could enable heavier payloads or longer missions for the Long March 10, which is slated to support crewed lunar landings in the 2030s. Successful booster recovery shows China’s progress in mastering reentry and landing techniques, though the module’s composite share still leaves room for weight‑saving improvements. Observers should watch upcoming tests of the Long March 10’s net‑assisted and vertical‑landing recovery systems to see which method China adopts for routine reuse.
