The solid sample can be analyzed without being dissolved. In the past, if we dissolved material, we would need at least 10 or tens of milligrams sample. Now we need only one nanogram."

Storyline


The first batch of lunar soil samples, which were sent to 31 labs of 13 Chinese research institutions in July, were returned by those who have completed their preliminary studies.

The first batch contained 31 samples, totaling 17.4764 grams, including powder, lithic fragment and polished sections.

Li Xianhua, a professor of the Institute of Geology and Geophysics under the Chinese Academy of Sciences, returned 1,916 milligrams of soil. He said technology breakthrough ensured minimum sample loss.

"Now there is huge development in technologies. We use an ion microprobe to sputter [on sample], leaving a very tiny trace for direct instrumental analysis. The solid sample can be analyzed without being dissolved. In the past, if we dissolved material, we would need at least 10 or tens of milligrams sample. Now we need only one nanogram," said Li.

Li said he is very excited to do experiments with samples brought back by China's Chang'e-5 probe in last December. For him, the soil samples play an essential part in his research.

"I mainly study the age of the Moon, its geochemical isotope characteristics and the formation of lunar basalt," said Li.

The lunar samples could hold the key to telling the Moon's exact age. Scientists might also be able to determine the age of the youngest magmatic activity on the Moon and master clues to explore secrets of Earth.

"We use Moon as a comparison to study Earth. The Earth is still an active planet but there is few records of its ancient times. Records of Moon are quite old, so studying its evolution can supplement the Earth's evolution history," said Li Chunlai, deputy chief designer of the third phase of lunar exploration project, and chief engineer of the ground application system.

The second batch of samples is now open for applications.
