Long March 10B Demo Flight: Launch Recap for 10 July 2026

What happened?

The Long March 10B completed its inaugural demonstration flight successfully on 10 July 2026 at 04:15 UTC, lifting off from Commercial LC-2 at the Wenchang Space Launch Site in the People's Republic of China. The rocket is a single-stick, next-generation heavy-lift launch vehicle developed by the China Aerospace Science and Technology Corporation (CASC) as the core variant of China's crewed lunar rocket family.

The Long March 10B is the reusable-oriented, single-core configuration of the broader Long March 10 program, distinguished from the three-core variant designed for lunar missions. This demonstration flight validated the vehicle's core stage, propulsion, and flight systems ahead of operational service.

Did the launch succeed?

Yes. The mission is officially listed as a Success. The demonstration flight met its primary objectives, marking a key milestone for CASC's next-generation launch fleet and China's ambitions to land astronauts on the Moon before 2030.

Mission at a glance

What is the Long March 10B?

The Long March 10 series is China's heavy-lift launch system engineered primarily for crewed lunar exploration. The three-core version is designed to send a crewed spacecraft and a lunar lander toward the Moon, supporting a landing target before 2030. The Long March 10B is the single-core derivative, intended for launches to low Earth orbit, including crewed missions to China's future space station operations and next-generation crew vehicles.

According to CASC, the Long March 10 family uses clustered YF-100K kerolox engines derived from the proven YF-100 family that powers the Long March 5, 6, 7 and 8 rockets. The design incorporates provisions for booster recovery and reuse, aligning China's flagship rocket with the reusability trend led globally by operators such as SpaceX.

Why does this launch matter?

This demonstration flight is a foundational step toward China's crewed lunar landing goal. Validating the single-core Long March 10B first reduces risk for the far more complex three-core configuration, which must lift substantially heavier payloads on translunar trajectories.

• It confirms the performance of the new YF-100K engine cluster in flight.
• It qualifies Wenchang's Commercial LC-2 pad for next-generation heavy-lift operations.
• It advances the timeline for China's stated goal of a crewed Moon landing before 2030.

Wenchang, located on Hainan Island near the equator, is China's newest and southernmost spaceport. Its low latitude provides a performance advantage for launches to equatorial and geostationary transfer orbits, and it is the only Chinese site capable of handling the country's largest rockets.

What comes next?

With the demonstration flight complete, CASC is expected to proceed toward operational Long March 10B flights and, ultimately, the three-core Long March 10 that will underpin crewed lunar missions. Each subsequent flight builds confidence in the hardware ahead of high-stakes human spaceflight.
