Chang'e 6 lunar sample return mission returns with samples from moon's far side

China's Chang’e-6 lunar probe successfully returned the world's first samples from the far side of the moon, marking a significant achievement for China's space program. The re-entry capsule carrying the lunar material landed in Inner Mongolia after being released from the uncrewed probe. This mission, named after the Chinese moon goddess, involved collecting rock and soil from the South Pole-Aitken basin, one of the moon's largest craters. The samples could provide insights into the moon's early history and shed light on Earth's impact history. China's success in retrieving material from the far side of the moon distinguishes it from previous missions by the US and the former Soviet Union, which focused on the near side. The scientific community anticipates that analyzing these samples will deepen our understanding of the moon's geology and potentially reveal information about the lunar mantle. China's future lunar missions aim to establish an International Lunar Research base and eventually land a Chinese astronaut on the moon, further advancing exploration and research in space.

One thing they seems to have got working fairly reliably is the lunar landing of the probe using image processing to guide the final approach and touch down. It seems to have worked well in this and the previous mission, there are videos on youtube of that.

The other component is the autonomous docking of the return probe in lunar orbit.

Soviets have done a lunar sample return, but they had a probe that would lift off directly into a earth return trajectory, but that seems to have limited both the liftoff mass and the possible zones in moon from which it can lift off. This seems a much more complex mission than that.

Also some animated videos of the misson show a skip re-entry back to earth, don't know if it is the case during this particular flight.

They only linked to other articles of the guardians but not to the official announcement.

Official announcement by the CNSA: https://www.cnsa.gov.cn/n6758823/n6758838/c10565180/content....

Congratulations for such an achievement!

Super impressive. A return mission from the far side is very technically difficult, and pulling it off paves the way for a staffed lunar lander on the far side.

I sincerely hope there's no moonseed in it.

What are they expecting to be different about samples from the moon's far side to those previously collected?

Do either China or the US have plans to attempt a Mars sample return? Does China have the rocket power to attempt such a mission? The US seems focused solely on the return moon missions, with any Mars mission presumably behind at least 5 more major Artemis missions that are scheduled through 2031.

Now let's see China accomplish the same with all-analog circuitry

The international moon base plan is fascinating.

(nuclear power plans by Russia not so much)

Is there enough gravity on the moon to prevent the long-term health problems from the space station like bone, muscle and vision loss?
