And about 50 years ago, three astronauts on the United States Apollo 8 mission became the first people to see it with their own eyes.Lunar orbiters have shown the moon's tw▓o sides are very different: the near side is re▓latively flat, while the far side is thickly dotted with impact craters of different sizes.Scientists believe that ▓the lunar crust on the far side is much thic▓ker than the near side. However, the reason is still a mystery. Only on site exploration might reveal th▓e secrets.The moon and Earth shared a similar "childhood." But traces of the remote past on Earth ▓have been erased by geological activities.
