After 44 years, China once again brought the lunar soil back to the earth, which is nearly 10.8 times heavier than the Soviet Union.

Chang'e-5 is the most complex spacecraft system developed by China to date, and has achieved five "first" initiatives in China's aerospace engineering, including sampling on the lunar surface, taking off and landing on the lunar surface, unmanned rendezvous and docking in lunar orbit, and carrying the moon Return the samples to the earth and establish a storage, analysis and research system for Chinese lunar samples.

PolyU research team develops sampling and packaging device

The scientific research team of the Hong Kong Polytechnic University is the only institution in Hong Kong to participate in the "Chang'e 5" mission. The team is responsible for the development of a "surface sampling execution device" so that the sampling device can successfully complete the lunar surface sampling and packaging.
