After landing in the South Pole-Aitken (SPA) basin, Chang'e 6 gathered about 2 kilograms of lunar material from the surface and up to 2 meters below ground. These samples are essential for studying the Moon's geological history and development.
The return journey began with the ascent vehicle launching from the lunar surface, carrying the samples into lunar orbit. The ascent vehicle then docked with the orbiter, transferring the sample container to prepare for the trip back to Earth.
Fuel-Efficient Return Trajectory
The trans-Earth injection burn propels the spacecraft from lunar orbit toward Earth, optimizing fuel use by leveraging orbital mechanics. This maneuver allows the spacecraft to coast for most of the journey, conserving fuel and enabling more resources for payload and critical systems. Mission control monitors the trajectory, making adjustments as needed for a precise return.
Reentry and Landing
As Chang'e 6 nears Earth, it performs trajectory corrections to ensure the correct reentry angle and speed. The reentry module, containing the lunar samples, separates from the orbiter and uses parachutes to land safely on Earth. This process ensures the samples remain intact for analysis.
The mission's careful planning and execution highlight China's commitment to efficient and safe space exploration. The lunar samples are expected to provide new insights into the Moon's geology, especially its asymmetrical features compared to the near side.
Chang'e 6 demonstrates China's growing capabilities in space exploration and offers valuable scientific data to the global community. With plans for future lunar missions and a potential crewed lunar base by 2036, the success of Chang'e 6 lays a solid foundation for continued exploration and international cooperation.
