[Chang’e 5 series #2] No second chance for the lunar sampling!

(Reference: China`s Chang e 4 lunar probe landed on the surface of the moon.) Talking about the challenges of the Chang'e 5 project, Professor YUNG Kai-leung, Sir Sze-yuen Chung Professor in Precision Engineering, Chair Professor of Precision Engineering and Associate Head of Department of Industrial and Systems Engineering of the Hong Kong Polytechnic University (PolyU) said, “As our system needed to operate on the sun-facing side of the Moon where the ground temperatures could be as high as 110 degree Celsius, this innovation had to be highly sophisticated and capable of functioning under extremely high temperatures. It also needed to withstand the extreme space environment during travel to and landing on the Moon which meant enduring impact and shock during lift-offs and landings, high vacuum on the moon, exposure to solar wind and cosmic rays, as well as high-speed re-entry to Earth’s atmosphere.”“To meet the limited payload requirement, we had to be innovative in our mechanism design and be stringent in weight control. For example, the two samplers are more than a tool to acquire lunar regolith. They are also used to pick up and move the sample container from the lander to the ascender atop,” Professor Yung continued.(The video is broadcasted in Cantonese) For details about PolyU-made space instruments complete lunar sampling for Chang’e 5, please visit the PolyU website.

[Chang’e 5 series #1] Why the lunar sampling is related to Hong Kong?

In support of the Nation’s first lunar sample return mission, a research team at The Hong Kong Polytechnic University (PolyU) developed and manufactured one of the key systems for this historic undertaking, namely the “Surface Sampling and Packing System”, in collaboration with the China Academy of Space Technology. The PolyU-developed system accomplished the tasks of automatic sample collection and packaging on the lunar surface following the soft landing of the Chang’e 5 probe on 1 December 2020. Chang'e-5 is the world’s first lunar-sample return mission in more than 40 years, aiming to bring back a large amount of lunar samples of up to two kilograms via robotic means. The probe adopts two methods of moon surface sampling: one uses a robotic arm for multiple-point surface sample collections, and the other is to drill underground. The team led by Professor YUNG Kai-leung, Sir Sze-yuen Chung Professor in Precision Engineering, Chair Professor of Precision Engineering and Associate Head of Department of Industrial and Systems Engineering, PolyU, was tasked in 2011 to develop the “Surface Sampling and Packing System”, a comprehensive system for lunar surface sampling, packaging and sealing.
