APTOPIX China Moon Mission

Flags with the logo of the Communist Party of China fly in the breeze near a launch pad at the Wenchang Space Launch Site in Wenchang in southern China's Hainan province, Monday, Nov. 23, 2020. Chinese technicians were making final preparations Monday for a mission to bring back material from the moon's surface for the first time in nearly half a century — an undertaking that could boost human understanding of the moon and of the solar system more generally.
