On Thursday, the Chang’e-6 probe achieved a significant milestone by successfully transferring the first-ever samples collected from the far side of the moon from its ascender to the returner module. This marks a pivotal moment in lunar exploration as these samples are set to make their journey back to Earth.
The ascender of China’s Chang’e-6 probe rendezvoused and docked with the orbiter-returner combination in lunar orbit at 2:48 p.m. Beijing Time, according to the China National Space Administration. This complex maneuver is critical in ensuring the safe transport of the lunar samples across approximately 380,000 kilometers back to Earth.
Journey of the Lunar Samples: Step by Step
Step 1: The Chang’e-6 probe began collecting samples after landing on the far side of the moon on June 2. Using advanced drilling and scooping equipment, the probe gathered soil and rock samples, which were carefully packaged in a canister-like container located atop the ascender.
Step 2: After the collection, the ascender lifted off from the lunar surface to rendezvous with the orbiter-returner module waiting in lunar orbit. This mid-space docking is a highly technical feat, demonstrating China’s growing capabilities in space exploration.
Step 3: Upon successful docking, the samples were transferred to the returner module. The ascender’s mission concluded with this handover, and it will remain in lunar orbit.
Step 4: The orbiter-returner module will then adjust its trajectory to prepare for the journey back to Earth. This involves precise calculations to ensure a safe re-entry trajectory through Earth’s atmosphere.
Step 5: As the module approaches Earth, the returner will separate from the orbiter and enter the atmosphere, protected by heat shields to withstand the intense heat of re-entry.
Step 6: Finally, the returner will deploy parachutes to slow its descent and land safely at a predetermined site, where recovery teams will retrieve the lunar samples for scientific analysis.
Significance of the Mission
The Chang’e-6 mission represents a significant advancement in lunar exploration, particularly in studying the far side of the moon, which has been less explored due to its communication challenges with Earth. The samples returned could offer unprecedented insights into the moon’s geology and the early history of the solar system.
This mission not only showcases China’s growing prowess in space technology but also contributes valuable data to the global scientific community, fostering international cooperation in space exploration.
