The "local specialties" brought back by the Chang'e-5 probe

There are new research findings!

Nanjing University and others found

It is expected that the moon soil will produce oxygen and fuel

On May 8, the reporter learned from Nanjing University that the team of Academician Zou Zhigang and Professor Yao Yingfang of the university, in collaboration with the Chinese University of Hong Kong (Shenzhen) and the University of Science and Technology of China, discovered that some components in the lunar soil samples brought back by Chang'e 5 can act as catalysts to convert water and carbon dioxide into oxygen, hydrogen, methane and methanol under the action of sunlight.

Based on this discovery, researchers proposed that in the future, the moon's own resources could be used to build a lunar base to support deep space exploration, research and travel.

Chang'e 5 probe returns from the moon

Bringing back the first batch of lunar soil in the 21st century

Preliminary measurements show that this batch of lunar samples weighs about 1,731 grams

For the first time, my country has achieved the return of samples from an extraterrestrial object

July 12, 2021

Lunar sample scientific research work officially launched

Nearly two kilograms of lunar samples

A total of 17.4764 grams were distributed to 13 scientific research institutions

From "landing on the moon to collect soil" to "soil research"

Scientists come face to face with lunar soil

Asking for answers from the “Priceless Land”

The study of lunar soil has brought these results

13 scientific research institutions

A little more than 17 grams of sample

The "fight for every inch of land" research also brought a series of results

The geological life of the moon has been "extended" by 1 billion years

In the early morning of October 8, 2021, the world's top academic journal Science published an online research paper titled "Age and Composition of Chang'e-5 Young Basalts". This is the first academic achievement published on the Chang'e-5 returned samples.

A team from the Beijing Ion Probe Center of the Institute of Geology, China Geological Survey, has found that magma activity continued on the moon until 1.96 billion years ago, extending the currently known geological life of the moon by 1 billion years.

The youngest basalt on the moon is about 2 billion years old

On October 19, 2021, research by the Chinese Academy of Sciences proved that the Chang'e-5 lunar samples are a new type of lunar mare basalt, and provided new insights into the age and source properties of the magma in the Chang'e-5 landing area.

In the latest study, researchers analyzed more than 50 uranium-rich minerals in the basalt fragments of the Chang'e-5 lunar sample, confirming that the "youngest" basalt on the moon is about 2 billion years old.

Magma activity determines the life and death of a planet. When magma activity stops, it also means the end of the planet's life. This study has delayed the time when the moon's magma stopped by 800 million years.

The Chang'e 5 landing area may have experienced multiple volcanic eruptions

In December 2021, the Purple Mountain Observatory of the Chinese Academy of Sciences and the Nanjing Institute of Geology and Paleontology discovered through research on the Chang'e-5 lunar samples that the Chang'e-5 landing area may have experienced multiple volcanic eruptions in history.

Chang'e 5 reveals lunar surface water content in landing area

A research result was published in Science Advances on January 8, 2022. The planetary science team of the Institute of Geology and Geophysics of the Chinese Academy of Sciences, in collaboration with teams from the Shanghai Institute of Technical Physics, the National Space Science Center, and other teams, obtained for the first time the water content under in-situ conditions on the lunar surface.

The latest research shows that there are about 120 grams of "water" in 1 ton of lunar soil and about 180 grams of water in 1 ton of rock. The research team said that the water detected by the spectrometer refers to water molecules or hydroxyl groups in minerals, which can only be converted into drinkable water under certain conditions.

Establishing a new lunar age function model

On February 15, 2022, a research result was published in the international academic journal Nature.

The Institute of Space Information Innovation of the Chinese Academy of Sciences and its collaborators used the isotopic ages of the Chang'e-5 lunar samples and the statistics of impact craters in the landing area to establish a new and more accurate age function model based on the currently commonly used lunar age function, providing a more accurate time scale for lunar and planetary science research.

Uncovering the mysteries of space weathering

A research team from the Institute of Geology and Geophysics, Chinese Academy of Sciences, in collaboration with researchers from the Beijing High Pressure Science Center and the National Space Science Center of the Chinese Academy of Sciences, obtained information on the space weathering of silicates, oxides, phosphates and sulfides on the surface of individual Chang'e-5 lunar soil particles.

Research shows that the space weathering of Chang'e-5's lunar soil is mainly caused by the combined effects of micrometeorite impacts, solar wind and cosmic ray radiation.

In addition to these research results

13 scientific research institutions are also studying lunar samples

Conduct research in different areas

Related results will also be released in due course

Looking forward to more surprises!
