Chang'e 6

• 1. Mission Architecture And Design

  ›

  The Chang'e 6 spacecraft launched from Wenchang Space Launch Site on Hainan Island at 09:27 UTC on the 3rd of May 2024. It was built as a copy of and backup to the earlier Chang'e 5 mission. The four-module configuration included a lander, an ascender, an orbiter, and a returner capsule. Engineers designed the lander to separate from the orbiter before touching down on the lunar surface. This lander carried both a drill and a scooping device for collecting samples. An ascent vehicle sat atop the lander portion of the probe. The estimated launch mass reached approximately 8,200 kilograms. The lander itself weighed about 4,800 kilograms while the ascent vehicle measured around 1,200 kilograms. These figures reflect the engineering relationship between the two missions.

• 2. Historic Far Side Landing

  ›

  Chang'e 6 touched down on the lunar far side at 22:23 UTC on the 1st of June 2024. This location lay within the southern mare of Apollo crater inside the South Pole-Aitken basin. Scientists chose this area because it might contain lunar mantle material ejected by the original impact that created the massive basin. The landing used autonomous obstacle avoidance systems with visible light cameras and laser 3D scanners. A cushioning system handled the freefall touchdown after engine cut-off during final approach. The Queqiao-2 relay satellite provided support for communication since direct contact is impossible from Earth's perspective. This marked the first successful soft landing on the lunar far side in human history. All previous sample returns came from the near side of the Moon.

• 3. Sample Collection Mechanics

  ›

  The robotic scoop and drill collected a total mass of 1935.3 grams from the lunar surface. Surface soil and rocks were gathered using the scooping device while subsurface samples required the drill mechanism. The hole left behind took the shape of the Chinese character zhong which means middle or center. This symbol represented China's name Zhōngguó and went viral on social media platforms like Weibo. The ascender module carried these samples into lunar orbit starting at 23:38 UTC on the 3rd of June 2024. It then docked with the orbiter module in space at 06:48 UTC on the 6th of June 2024. Sample transfer to the return capsule finished by 07:24 UTC that same day. The entire operation demonstrated unprecedented precision for robotic operations on the far side.

• 4. International Scientific Payloads

  ›

  Four international partners contributed instruments to the Chang'e 6 mission during its scientific payload phase. France provided DORN to study volatile transport between regolith and exosphere including water cycles. Italy supplied INRRI retroreflectors measuring distances from lander to orbit similar to Schiaparelli missions. Sweden offered NILS detectors for negative ions reflected off the lunar surface. Pakistan delivered ICUBE-Q CubeSat carrying optical cameras for magnetic field data collection. A mini-rover named Jinchan weighed approximately five kilograms with gold-sheeted insulation. This autonomous robot used micro solar panels and imaging infrared spectrometers for research. Jinchan detached after sample collection to photograph the lander from multiple angles. These collaborations expanded China's reach beyond domestic capabilities.

• 5. Orbital Rendezvous And Return

  ›

  The ascender entered circumlunar orbit at 23:38 UTC on the 3rd of June 2024 before docking with the orbiter. Orbital rendezvous occurred at 06:48 UTC on the 6th of June 2024 followed by sample transfer completion at 07:24 UTC. The service module fired engines around the 21st of June 2024 to begin Earth return. An atmospheric re-entry module weighing about 300 kilograms separated just before arrival. It performed skip reentry bouncing off the atmosphere once over the Atlantic Ocean. Final descent ended with parachute landing at 06:07 UTC in Siziwang Banner Inner Mongolia on the 25th of June 2024. Search teams reached the capsule within minutes using helicopters. The mission lasted roughly 53 days from launch to recovery. This sequence proved autonomous orbital operations possible without human intervention.
