According to a white paper on China’s space operations issued Friday, the government will conduct more space research investigation in the next five years.

The State Council Information Office produced a white paper titled “China’s Space Program: A 2021 Perspective.”

China will continue to study and build projects such as the space gravitational wave detection satellite, the Einstein probe satellite, and the advanced space-based solar observatory, according to the report. It will include topics such as the furthest reaches of the cosmos, time and space ripples, a panoramic perspective of the sun and Earth, and the quest for habitable planets.

China will also continue to explore frontier regions and conduct research in space astronomy, heliospheric physics, lunar and planetary science, space-Earth sciences, and space physics, according to the white document, in order to develop more unique scientific results.

China will also perform experiments and research on biology, life, medicine, and materials using space experiment platforms such as the Tiangong space station, the Chang’e lunar probe series, and the Tianwen-1 Mars mission. According to the white paper, it will allow China to advance humanity’s grasp of fundamental science.

China has established several initiatives to explore space and perform tests, progress research on fundamental ideas, and incubate significant research results, focusing on scientific problems such as the creation and evolution of the cosmos and the link between the solar system and mankind.

The energy spectrums of cosmic-ray electrons, protons, and GCR helium were measured precisely by the Dark Matter Particle Explorer (DAMPE) Satellite. Huiyan (Insight) Hard X-ray Modulation Telescope has been launched successfully.

China has made tremendous progress in examining the moon’s geology and underlying structure, thanks to its lunar exploration program.

“Chinese experts have received fresh insights into the evolutionary history of the moon by analyzing the shallow structure of the moon,” said Liu Jizhong, head of the China National Space Administration’s Lunar Exploration and Space Program Center, during the white paper’s press conference.

According to Liu, the researchers investigated lunar materials returned by the Chang’e-5 mission and discovered that the moon is around 1 billion years younger than previously thought.

They dated the moon’s youngest rock at roughly 2 billion years old, increasing lunar volcanism’s “life” by 800-900 million years longer than previously thought.

In terms of matter energy, Chinese scientists have identified new sorts of deep lunar material as well as delicate cosmic ray energy spectrum structures.

In terms of the space environment, they’ve developed new models of the interaction between solar winds and the moon, as well as a new understanding of the radiation dosage of lunar particles, according to Liu.

China has achieved a better grasp of the geological development of Mars by examining its surface structure and soil, as well as the composition of its rocks, through planetary exploration.

China has achieved mammalian embryonic development in space and in-orbit verification of the world’s first space cold atom clock, expanded understanding of the mechanisms behind particle segregation in microgravity, pulverized coal combustion, and material preparation, and achieved international research findings in space science with the help of the Shenzhou spacecraft series, the Tiangong-2 space laboratory, and the Shijian-10 satellite.
