This process involves the rover drilling about 2 meters deep into the moon’s surface and extracting around 2 kg of regolith (lunar soil). The sample container is then sealed, purged with nitrogen gas to prevent contamination, and transferred to the ascender module.
Storing Samples:
The container storing the lunar samples undergoes a rigorous heating and cooling process to ensure the preservation of pristine conditions. This procedure helps prevent any potential contamination from Earth’s environment during the return journey. Once sealed, the container is stored inside the ascender module, which separates from the lander and ascends to join the orbiter, Orbiting Palaeolithic Explorer-1 (OPE-1).
Returning Samples from the Far Side of the Moon:
The far side of the moon, also known as the “dark side,” is a significant challenge when it comes to returning samples. This area doesn’t have direct line-of-sight contact with Earth, which complicates communication between the mission team and the spacecraft. To overcome this obstacle, China opted for a relay satellite named Queqiao to facilitate communication. Queqiao is positioned at Earth-Moon L2 Lagrangian point, enabling it to transmit data between the Chang’e-5 spacecraft and the ground control team.
The Return Journey:
The return journey begins with the orbiter, OPE-1, launching the ascender module containing the samples into lunar orbit. The orbiter then docks with the service module, releasing the ascender and transferring control to it for the journey back to Earth. The ascender uses a powerful engine for its return trajectory towards Earth, leaving the orbiter behind.
Re-entry Process:
Upon approaching Earth’s atmosphere, a heat shield protects the sample container from the intense heat generated during re-entry. The spacecraft then parachutes down into the ocean where it is retrieved by a recovery team, securing the precious lunar samples for further analysis. Finally, these samples will be shared with the international scientific community to expand our understanding of the moon’s geology and history.
Chang’e-6, China’s upcoming lunar mission, is set to make history with its planned landing on the
