In recent years, China has made a big step forward in exploring the Moon. Three important probes (探测器) Chang'e 4, Chang'e 5, and Chang'e 6 were sent by China to the Moon.

2018
Chang'e 4 was launched (发射) on December 8, 2018, from the Xichang Satellite Launch Centre. Its main task was to land on the far side of the Moon. There was no spaceship landing there before. Chang'e 4 studied the Moon's soil and sent back many pictures. This probe helped scientists understand more about the far side of the Moon.

2020
Chang'e 5 was launched on November 24, 2020, from the Wenchang Spacecraft Launch Site, and it reached the Moon seven days later. Its main task was to collect rocks and soil on the near side of the Moon and bring them back to Earth. On December 17, 2020, Chang'e 5 returned with samples (样本).

2024
Chang'e 6 was launched in May, 2024. It collected samples from the far side of the Moon. This is important because it was the first samples from that part of the Moon. Chang'e 6 will help scientists learn more about the Moon's environment and history.

These probes help us understand the Moon better and prepare for future space exploration. And China will send more probes to explore other planets, like Mars.
