Lanyue is China’s two-person lunar lander, engineered to transport astronauts from lunar orbit down to the surface of the Moon and return them safely to orbit. Developed by the China Academy of Space Technology under the civil lunar exploration framework, the vehicle serves as the dedicated descent craft for the national objective of landing astronauts on the lunar surface before 2030.
Operating as a core element of the broader China space program, Lanyue relies on a split-vehicle architecture designed to balance heavy propellant requirements against rocket lift capacity. The spacecraft divides its nearly 26-metric-ton operational mass between a reusable crew landing stage and an expendable propulsion stage, while reserving payload room for surface gear and a mobile rover.
Following an integrated landing-and-ascent test conducted in Hebei Province in August 2025, flight engineers are working toward an uncrewed lunar test flight targeted for 2027. Successful execution of that uncrewed rehearsal will establish whether the vehicle can support a crewed landing attempt before the end of the decade.
What Lanyue Is
Lanyue is China’s crewed lunar lander under development by the China Academy of Space Technology (CAST), designed to land two astronauts on the Moon before 2030. According to Wikipedia, the vehicle’s name originates from a poem written by former Chinese leader Mao Zedong and translates roughly as “embracing the Moon.” Operating as a central flight element of the national lunar initiative, the craft takes over flight operations once astronauts reach lunar orbit inside their crew transport vehicle.
The spacecraft is built to support surface exploration rather than long-duration transit from Earth. Chinese flight designers engineered Lanyue to perform the powered descent from lunar orbit, provide environmental shelter on the surface, and execute the powered ascent back to rendezvous altitude. The lander operates in direct coordination with the Mengzhou crew capsule, which carries the astronauts between Earth and lunar orbit.
Developing a specialized lunar lander allows Chinese mission planners to avoid launching a single, massive spacecraft directly from Earth to the lunar surface. By splitting deep-space transit from the landing job, the China lunar lander program limits the mass required on each individual booster. Lanyue functions as the surface taxi for the broader China Moon landing initiative, maintaining life support systems, communications links, and surface exploration gear during operations on the Moon.
How the Lanyue Lander Is Built
The Lanyue lander weighs nearly 26 metric tons at operational mass and divides its systems across two distinct hardware modules: a landing stage and a propulsion stage. According to design specifications published on Wikipedia, the landing stage houses the crew compartment, the primary avionics, the surface communications antennas, and the landing legs that absorb ground impact. The propulsion stage carries the heavy propellant mass needed to slow the spacecraft down from orbital velocity during lunar descent.
Separating the propulsion stage during final descent reduces the mass the landing stage must control as it maneuvers toward touchdown. The propulsion stage fires its engines through the initial braking phase to cancel orbital speed, and then separates once its propellant is spent. The landing stage then completes the terminal descent, using its own variable-thrust engines to guide the vehicle down to a soft landing on the surface.
Beyond accommodating its two-person crew, Lanyue provides dedicated volume and structural mounting points for surface exploration equipment. The vehicle carries a lunar rover alongside specialized scientific payloads, giving the two astronauts ground mobility away from the landing site. The rover and equipment stow on the landing stage during transit, deploying after the vehicle settles onto the lunar soil.

Proving the Landing and Takeoff Sequence
China conducted the first integrated landing-and-ascent test of the Lanyue lander on 6 August 2025 at an outdoor test facility in Huailai County, Hebei Province. Reporting published by SpaceNews confirmed that the ground trial simulated a full lunar descent and landing sequence followed directly by a surface takeoff.
The test verified the vehicle’s flight control algorithms, structural landing gear, and engine throttle response across realistic operating transitions. Detailed test coverage from Space.com reported that the trial validated four specific engineering elements: landing and takeoff systems, flight control loops, subsystem interface compatibility, and automatic engine shutdown logic at ground contact. The contact shutdown procedure is critical because rocket engines must shut down at the exact instant the footpads contact the lunar soil to prevent thrust deflection from destabilizing the lander.
Validating that the guidance computer can command engine cutoffs while maintaining vehicle orientation clears the path for dynamic atmospheric and orbital testing. Engineers used data collected during the August 2025 trial to refine control software governing the transition between powered deceleration and surface contact.
How Lanyue Works With Mengzhou to Land a Crew
China’s mission flight profile relies on a two-rocket launch sequence to deliver Lanyue and its crew to the lunar surface. The architecture avoids requiring an unproven super-heavy launcher by splitting the spacecraft stack across two identical flights. As outlined in program reporting, the Long March 10 heavy-lift rocket launches Lanyue on one flight, while a separate Long March 10 launches the Mengzhou crew transport craft carrying the astronaut crew.
Both vehicles enter translunar trajectories independently and travel to lunar orbit. Upon reaching lunar orbit, Lanyue and Mengzhou perform an automated orbital rendezvous and dock. Two astronauts then open the transfer hatch, move out of Mengzhou, and enter Lanyue to prepare its flight systems for the landing attempt. The remaining crew member stays aboard Mengzhou to monitor orbital operations from space.
Lanyue undocks from Mengzhou and begins its orbital descent maneuver:
- The propulsion stage fires to slow the vehicle down from orbital velocity, absorbing the primary kinetic deceleration required for lunar approach.
- The propulsion stage separates from the stack during the final phase of descent once its onboard propellant is spent.
- The landing stage engines ignite to guide the vehicle through terminal approach, hazard detection, and a vertical touchdown on the surface.
- The two astronauts deploy the rover, set up scientific payloads, and conduct surface exploration operations.
- The landing stage ascent engine fires from the surface, lifting the crew back into lunar orbit while leaving the lower landing platform behind.
- Lanyue docks with Mengzhou in lunar orbit, transfers the two astronauts and collected samples, and separates before Mengzhou fires its propulsion system for the return trip to Earth.
Testing Timelines Ahead of the 2030 Landing Target
China has organized its crewed lunar development program around intermediate uncrewed flight tests to validate hardware before putting astronauts aboard. According to reporting from IEEE Spectrum, space officials have targeted an uncrewed flight of the Mengzhou spacecraft for 2026, followed by an uncrewed test flight of the Lanyue lander in 2027. Both orbital flights must succeed to keep the overall program on schedule for a crewed Moon landing before 2030.
Meeting the uncrewed test milestones requires parallel development across propulsion, ground facilities, and spaceframe manufacturing. A delay in the Long March 10 test program, or an anomaly during either the 2026 Mengzhou flight or the 2027 Lanyue orbital dress rehearsal, would force mission planners to adjust the crewed landing target. Each test verifies a separate set of operational dependencies, from high-speed atmospheric reentry to autonomous orbital docking in cislunar space.
If flight teams complete the uncrewed Lanyue mission in 2027 without major revisions, subsequent flights will focus on end-to-end integration across the two-rocket architecture.
