Sending a man to the moon will drive a series of scientific and technological innovations, such as materials and technology, and then create many jobs to improve China's competitiveness, blabla. Scientifically speaking, machine sampling is a bit stupid, not as flexible as human beings. Moreover, we don't know much about the moon at present, and the types of samples are not representative. If you send someone up, you can point to where to hit, without complicated program statements, and you can take it back for research and study when you see anything interesting. A famous example is that an astronaut of Apollo17 is a geologist. After landing on the moon, he saw an orange lunar soil, which was so special, so he put some back. Later, he took it to the laboratory and saw that it was volcanic glass. It was fun. The moon was not only gray and black, which made a group of scientists excited. The scientific research value of orange volcanic glass is certainly great, but I haven't read the relevant articles and I don't know.
