The mission “involves many engineering innovations, high risks and great difficulty,” the China National Space Administration said, as translated. The craft will collect samples by drilling into rocks and soil on the moon and taking samples from the lunar surface. “Landing on the far side of the moon is very difficult because you don’t have line-of-sight communications, you’re relying on a lot of links in the chain to control what is going on, or you have to automate what is going on,” said Neil Melville-Kenney, according to Reuters.
