Development of Sampling and Encapsulating Technologies for China's Deep Space Probes
The sampling and encapsulating technologies of deep space probe primarily study the collection of samples such as soil and fragmented rocks from the surfaces of extraterrestrial bodies.These samples,which carry a wealth of scientific information,are then reshaped and en-capsulated as necessary.The practice and research situations of China's sampling and encapsula-ting technologies are reviewed for deep space probes.The development of sampling and encapsu-lating technologies at domestic and foreign are introduced firstly.Then,the key technical break-throughs in the successful lunar sampling and encapsulating missions in China,such as profile lu-nar soil collection,surface lunar soil collection,sample encapsulation,ground verification and on-orbit operation,are described in detail.Furthermore,the applications of related technologies in China's subsequent deep space exploration missions are discussed such as lunar polar region ex-ploration,small celestial body exploration and sampling return,Mars exploration and sampling return.Finally,the future development trends and research directions of the technologies are looked forward.
