He received BSc (2001) and Ph.D. (2007) degrees in geochemistry from the University of Science and Technology of China. After completing his Ph.D., he came to IGGCAS for post-doctoral research and joined the comparative planetary science group as an Associate Professor in 2011. His main interest in the past decade was Mg isotope geochemistry and its application in tracing the deep carbon cycle. He is currently working on the formation and evolution of the Moon based on the exploration data and return samples of the Chinese Lunar Exploration Program.    Prof. TANG, Xuhai Wuhan University   Prof. Xuhai Tang is professor at Wuhan University. He got PhD degree at Imperial College London and was postdoc at Princeton University. Currently, he is the editorial board member of International Journal of Rock Mechanics and Mining Sciences. His group developed the system of Microscale Rock Mechanics Experiment (Micro-RME) and Accurate Grain-Based Model (AGBM), which is able to measure the rock-forming minerals under extreme conditions and determine their influence on the macroscale mechanical property of rocks. This system is especially useful to test the filling materials in fractures and arbitrarily-shaped meteorites. Additionally, his ground developed an Aifrac simulator, to model rock fracturing driven by Hydraulic-Mechanical-Thermal coupling process, such as the shock veins on asteroids. Prof. Tang’s achievement contributes to smarter energy exploitation and space exploration.

Space Instruments for Lunar Sample Acquisition awarded The Science and Technology Progress Award

RCDSE designed and manufactured the state-of-the-art “Surface Sampling and Packing System”, which successfully contributed to the National’s Chang’e 5 mission for lunar sample acquisition. This historical invention was awarded “The Science and Technology Progress Award -  2nd Class” (科學技術進步獎-二等獎) by China Aerospace Science and Technology Corporation (CASC) in recognition of PolyU’s scientific innovation and technological advancement, and also received an appreciation letter from The China Academy of Space Technology (CAST) for the University’s contribution to space instruments. The Chang’e 5 mission in 2020 was not only China’s first undertaking to acquire rocks and soil from the Moon’s surface but also the world's first attempt to do so for more than 40 years. PolyU was the only tertiary institution in Hong Kong to contribute to the Chang'e 5 mission. The PolyU-developed system “Surface Sampling and Packing System” is a highly sophisticated invention that uses robotic technology for lunar sample acquisition – an unprecedented method. It was developed by a research team led by Professor Yung Kai-leung , Sir Sze-yuen Chung Professor in Precision Engineering, Director of Research Centre of Deep Space Explorations, Chair Professor of Precision Engineering & Associate Head, Department of Industrial and Systems Engineering. Prof Yung has also been individually bestowed “The Science and Technology Progress Award -  2nd Class".

Award-winning Project by RCDSE: Camera Pointing System for China’s Lunar Exploration Missions (Chang'e 3 and 4)

Research Team led by Prof. Yung Kai-leung of the Research Centre for Deep Space Explorations which received the Gold Medal with Congratulations of the Jury at the Geneva Inventions Expo lately. The team is the only university in Hong Kong taking part in the Nation’s space missions and actively developing instruments for the national space mission by leveraging its expertise in precision engineering. The awarded project entitled “Camera Pointing System for China’s Lunar Exploration Missions (Chang'e 3 and 4)”. Installed on top of the lunar lander, it facilitates panoramic image capturing and rover movement observation on the moon, and helps construct a precision 3D model of the landscape for safe rovering. With a complex design and a weight of only 2.8 kg, it is sturdy enough to protect the camera against shock and vibration during the space mission and ensure its proper functioning under the extreme lunar environment. The invention was completed and successfully deployed on the Moon front surface with the Chang’e 3 and Moon far side with the Chang’e 4 missions of China’s Lunar Exploration Programme.

RCDSE study found impact remnants on the Moon that may provide source of water

A study led by the National Space Science Center of Chinese Academy of Sciences and joined by Prof. Wu Bo, Associate Director of Research Centre for Deep Space Explorations and Associate Head of Department of Land Surveying and Geo-informatics of PolyU, has found carbonaceous chondrite remnants of an impactor in a young lunar crater formed within one million years, a first-time discovery of such fragments by in-situ investigation on the far side of the Moon. Scientists suggests that carbonaceous chondrite-like meteorites may provide 10 to 20% of the sources of water to the present Moon. Prof. Wu’s involvement in the research was to use innovative 3D mapping technology to create a detailed 3D topographic model of the 2-m size crater from the lunar surface images acquired by the Yutu-2 rover of Chang’e-4. The 3D morphological characteristic of the crater is critical to judge if the crater was resulted from a meteorite impact or not. The results were published in the scientific journal Nature Astronomy ( Please refer to the following links for the media interviews:  Ta Kung Pao - China News - 北京晚報 - The Cover - Sina - Sohu - Toutiao - 一點資訊 -
