Chang’e 6 Mission

About Chang’e 6 Mission
Chang’e 6 is a lunar lander and sample return mission that successfully reached the Moon’s far side, landing in the South Pole-Aitken Basin. It was launched on May 3, 2024, at 09:27 UT (5:27 p.m. Beijing Time) using a Long March 5 rocket from the Wenchang Satellite Launch Center. The mission returned lunar samples to Earth on June 25.
Spacecraft and Components
With a design resembling the Chang’e 5 mission but some payload modifications, Chang’e 6 weighs around 8,200 kg. The spacecraft consists of four main parts: an orbiter, a return vehicle, a lander, and an ascender. The entire system enters lunar orbit, where the lander and ascender separate to land on the Moon. The lander weighs roughly 3,200 kg when it touches down. Lunar samples are gathered and stored in the ascender, which lifts off and reunites with the orbiter-return vehicle, transferring the sample container to the return vehicle. This return capsule then travels back to Earth, reentering the atmosphere and landing safely with the samples.
The propulsion system for entering lunar orbit uses a 3,000 N engine. Solar panels generate power for the spacecraft. Chang’e 5 had a robotic arm equipped with a scoop, a coring drill, and a sample chamber, while the Chang’e 6 mission features several additional instruments: a landing and survey camera system, the Detection of Outgassing RadoN (DORN) device from France, the Negative Ions at the Lunar Surface (NILS) instrument contributed by Sweden and the European Space Agency (ESA), and a laser retroreflector (INRRI) from Italy. A Pakistani cubesat, ICUBE-Q, and a small rover are also part of the mission’s equipment.
Mission Timeline
Chang’e 6 entered lunar orbit on May 8, 2024, at 02:21 UT, achieving an initial altitude between 200 km and 380,000 km, and gradually circularized its path. On May 8, it also released the ICUBE-Q cubesat. The spacecraft spent 20 days orbiting to pinpoint a suitable landing site before the lander separated. The lander touched down on June 1 at 22:23 UT (6:23 a.m. Beijing Time, June 2) in the southern Apollo crater, located at coordinates 41.6385° S, 153.9852° W. Following the landing, solar panels, antennas, and scientific instruments were deployed, with communication established via the Queqiao-2 relay satellite for consistent data transmission from the Moon’s far side.
The mission aimed to retrieve about 2 kg of lunar material, utilizing a robotic scoop and drill to collect samples from the surface and up to 2 meters deep. The samples were loaded into the ascender, which took off on June 3 at 23:38 UT (7:38 a.m. Beijing Time, June 4). The ascender docked with the orbiter-return vehicle on June 6 at 06:48 UT, transferring the samples by 07:24 UT. The ascender was subsequently discarded to crash on the Moon. The orbiter-return vehicle departed lunar orbit on June 21, employing a skip reentry maneuver to deliver the samples to Earth on June 25. The capsule successfully landed in Siziwang Banner, Inner Mongolia, at 06:07 UT (2:07 p.m. Beijing Time), returning 1.9353 kg of lunar material.
