The lunar lander, named Lanyue ("embracing the moon"), is a newly developed extraterrestrial descent and ascent vehicle for China's first manned lunar exploration mission. Composed of a landing module and a propulsion module, it will primarily be used to ferry astronauts between lunar orbit and the lunar surface. Capable of carrying two taikonauts on round trips, along with a lunar rover and scientific payloads, it will support crewed missions to and from the moon, serving as a life-support, energy, and data center while its crew is on the lunar surface.

The testing was designed to validate lunar surface landing and takeoff system design, control solutions, touchdown shutdown strategies, and interface compatibility between the GNC (guidance, navigation, and control computer) and propulsion subsystems. The success marks a breakthrough in the research and development of China's manned lunar exploration program.
