China’s CMSA Tests Long March 10 Reusable Booster and Mengzhou Spacecraft in Single Dramatic Flight

China Manned Space Agency Long March 10 reusable booster propulsive landing South China Sea after Mengzhou launch abort test.
CMSA tested the Long March 10 reusable booster and Mengzhou spacecraft abort system in a single flight on February 10, 2026, successfully landing the rocket at sea after capsule escape at Max-Q.

China Manned Space Agency has executed a single, extraordinary test flight combining a launch abort system demonstration for the new Mengzhou crew capsule with a fully successful propulsive landing of the Long March 10 booster—the country’s most advanced reusable rocket test to date. Conducted on Tuesday, February 10, 2026, from Wenchang Space Launch Site on Hainan Island, the subscale booster climbed through maximum aerodynamic pressure, released the capsule in a simulated emergency, then reignited its YF-100 engines to descend precisely onto the South China Sea. The achievement brings China’s 2030 lunar landing goal measurably closer.

The problem China Manned Space Agency and its engineering contractors set out to solve is not whether China can reach the Moon—it already landed rovers there. The problem is whether it can land humans there safely, repeatedly, and affordably. Every crewed lunar program in history has faced the same bottleneck: rockets are expensive, capsules are complex, and the margin between success and catastrophe is measured in milliseconds.

What the CMSA team demonstrated on Tuesday is a system designed to break that bottleneck. The Long March 10 is not a single rocket but a family of configurations. For lunar missions, it will fly with three first-stage cores clustered together—21 engines burning kerosene and liquid oxygen—capable of lifting 70 metric tons to low-Earth orbit and pushing the 26-ton Mengzhou spacecraft toward the Moon. But the test this week used a subscale single-core version to validate something more fundamental than thrust: the ability to survive failure.

The basic function of the launch abort system is simple to describe, excruciatingly difficult to engineer. At the moment of Max-Q, when aerodynamic forces claw most violently at the vehicle, the abort motors must fire with enough instantaneous thrust to tear the crew capsule away from a rocket that may be seconds from disintegration. The Mengzhou capsule did exactly that, pulling clear, deploying parachutes, and splashing down in the sea. NASA and SpaceX performed similar tests with Orion and Dragon. Both expended their boosters in the process. The Long March 10 did not.

Remarkably, after the capsule escaped, the booster continued its ascent as if nothing unusual had occurred. It climbed into space, reentered the atmosphere, reignited its engines at altitude, and flew itself to a pinpoint landing next to a recovery barge. According to China Aerospace Science and Technology Corporation, the state-owned giant that builds both the rocket and spacecraft, this marks the first time China has successfully demonstrated vertical takeoff, vertical landing on a booster of this scale under realistic abort conditions.

Still, the achievement carries an honest limitation that the engineers themselves do not obscure. This was a subscale test. The booster flown Tuesday is a pathfinder for the full Long March 10, not the vehicle itself. The Mengzhou capsule tested was a prototype, not the human-rated production version scheduled for its first orbital flight later this year. CMSA explicitly states that the test verified “functional performance” and “interface compatibility”—engineering language that translates to: we have proven the concept, but the path from here to human certification is measured in additional test flights, not weeks.

What makes this matter, ultimately, is not the spectacle of a rocket landing itself in the ocean—though the footage released by Chinese state television is genuinely stunning. What matters is the convergence of capabilities. Mengzhou is designed to be reusable. The Long March 10 booster is designed to be reusable. The lunar lander, still unnamed but already in ground testing, will be reusable in its ascent stage. China is not building an Apollo-style architecture, where almost everything is discarded after one use. It is building something closer to what NASA envisions for Artemis, but with a compressed timeline and a different set of industrial partners.

The innovator of this integrated architecture is, institutionally, China Manned Space Agency, which sets the requirements and manages the program. But the engineers who made Tuesday’s test possible are distributed across CASC’s sprawling enterprise: the designers at the China Academy of Launch Vehicle Technology who adapted the YF-100 engine for deep-throttling reentry burns; the software team at the Shanghai Academy of Spaceflight Technology who wrote the guidance algorithms that landed a 20-story structure on a moving barge; the technicians at Wenchang who mated the abort test article to the booster in half the time such integrations usually require. According to CMSA’s post-mission statement, the flight accumulated “valuable flight data and engineering experience” that will inform “subsequent manned lunar exploration missions.”

Reported by Xinhua News Agency, the test comes as NASA prepares to launch Artemis II, a crewed lunar flyby, as soon as March 2026. The contrast in schedules is often framed as a race, but the engineering reality is more layered. The United States has Orion and SpaceX’s Starship under development. China now has Mengzhou and a reusable booster that just proved it can survive an abort. The competition is not who lands first; it is who can land sustainably, with hardware that flies again.

What comes next is documented in CMSA’s roadmap. Mengzhou will attempt its first orbital test flight later this year, launching on a Long March 10A—the single-core reusable variant—to dock with the Tiangong space station. That flight will carry no crew but will validate life support, navigation, and reentry systems. If successful, China will have human-rated its new spacecraft in roughly half the time the Orion program required.

For the rest of us, watching from a distance, the significance of Tuesday’s test is not that China is catching up. It is that China is choosing a different path. Reusable rockets, abort-on-the-pad capability, in-flight escape validation, propulsive landings at sea—these are not legacy Apollo technologies. They are the tool kit of a spacefaring nation that intends to stay on the Moon, not just visit. The booster that landed in the South China Sea on Tuesday will be inspected, refurbished, and flown again. That is the actual breakthrough.
