CHANG’E 5 (CNSA Lunar Probe and Sample Return)

And all the rocks from young impact craters have been determined younger than 1 billion years. However, we know less about what happened to the moon in the age gap between 3 billion years and 1 billions. Chang'e-5 mission has set the goal to fill this critical gap. The 1,731 grams of drilled and scooped lunar material will help to reveal more insights of the moon's geological history. In the past two weeks, the studies led by Institute of Geology of Chinese Academy of Geological Sciences have produced 4 high-impact papers published in Science and Nature journals. The results not only refreshed our knowledge of the moon’s geological history, but also proposed new questions. By analyzing the lead isotope ratios of the samples, the researchers found the samples are about 2 billion years old, that is about 1 billion years younger than volcanic samples returned by Apollo missions. Now we can surely say the moon is still geologically active 2 billion years ago. The finding not only sheds light on the history of the moon, but its importance also extends to other rocky planets in the solar system. The new data can improve the accuracy of the predictions by crater statistics. The updated model can then be used to date unsampled surfaces on the moon, and as well other planetary bodies that are hard to reach. Besides the age, we also need to know what is the source that supports the volcanic activities to a longer time. One hypothesis is this region is rich in potassium, rare earth elements, and phosphorus, which in combination called KREEP, which can provide sustaining heat from radioactive elements. Surprisingly, the samples only have a modest KREEP component, far below what is predicted from the model based on Apollo samples. Thus, these results strongly suggest that the idea of KREEP-induced heating for the generation of these youngest lunar magmas requires further investigation or the consideration of other mechanisms. Another theory is higher content of water in the mantle significantly reduced its melting pointing, so less amount of heat was needed for the volcanic activities. After analyzing the samples, researchers derived a maximum water abundance that is notably at the lower end of that derived from Apollo basalts and lunar meteorites, indicating a dry lunar mantle that lacks a reservoir to lower its melting point. By excluding the two major mechanisms, the question is raised on what the actual driving force of the sustained volcanic activity of the moon is. The authors propose to consider alternative explanations such as tidal heating or a distinct source mineralogy supporting lower melting temperature of the mantle.

Through an analysis of detection data obtained by China’s Chang-e 4 lunar probe, researchers have made a series of scientific discoveries of its landing site.

China’s National Museum is actively preparing to exhibit the lunar soil samples its Chang’e-5 lunar probe brought back last December. It marked the first time after 44 years human beings were able to collect lunar samples. The museum has reportedly designed a special container to store the samples. Its design was greatly inspired by ancient Chinese copper goblets.

For more: https://www.cgtn.com/video China's Chang'e-5 lunar probe returned to Earth, without a hitch, on Thursday morning. The probe spent 23 days in space and brought home soil and rock samples from the moon. The samples will be used for space research. They are the first to be collected from the moon in more than 40 years, after the U.S. and the Soviet Union. Chinese President Xi Jinping congratulated the Chang'e-5 team for the mission accomplished. The mission was a lot of firsts for China, including the first lunar surface sampling and sealing, first lift-off from the moon, first rendezvous and docking in lunar orbit, and the first spacecraft carrying samples to re-enter the Earth's atmosphere. Its success bodes well for China's three-step lunar exploration program, which began in 2004, of orbiting, landing, and bringing samples back to Earth. What can be learned from the lunar samples? What's next for China's space missions? And what's the significance of the Chang'e-5 success for space exploration?

China's Chang'e-5 mission has successfully returned to earth after weeks of space travel, bringing back the first fresh samples of rocks and debris from the moon in more than four decades. Lead scientist at The Royal Institution of Australia Alan Duffy has more. #China #Change5Mission #Debris

China's space agency says it's willing to share lunar samples with global community. What are the other possibilities for international collaboration in space exploration?

Other nations have also made achievements in lunar exploration. The former Soviet Union -- now Russia -- the US, India, and Europe have also embarked on multi-billion-dollar missions to discover the secrets of outer space.

China announced details on the successful Chang’e-5 mission in a news conference this afternoon in Beijing. Zheng Yibing files this report from the National Space Administration.

Chinese President Xi Jinping has expressed his congratulations for the success of the Chang'e-5 lunar mission.

The China National Space Administration has announced the Chang’e 5 returner module is set to land in Mongolia later today. On board are around two kilograms of moon rocks and dust. The mission has made China the first country to have retrieved these samples since the 1970s. And for the Chinese government it’s also way of showing the world how advanced it is, when it comes to space exploration. Michael Hartlep has the details.
