What countries have been to the moon?

Could you elaborate on the historical achievements of space exploration, specifically focusing on which countries have successfully sent missions to the moon? This remarkable feat represents a significant milestone in the evolution of space technology and human exploration. The question begs to know not just the names of these pioneering nations but also the significance of their lunar missions in terms of scientific discovery, technological advancement, and global impact. I am interested in understanding the context and implications of these lunar landings, as well as the potential for future exploration of our celestial neighbor.
