Frequently Asked Questions

QWhat exactly is Chang'e 4?

Chang'e 4 is a robotic spacecraft mission, part of the second phase of the Chinese Lunar Exploration Program. It's known for being the first spacecraft to land on the far side of the Moon, a feat that hadn't been accomplished before. This mission includes a lander and a rover, which have been exploring the Moon's surface since January 2019.

QHow did Chang'e 4 get its name?

Named after the Chinese moon goddess, Chang'e, this mission follows a tradition of naming lunar exploration missions after this mythological figure. The number 4 in its name signifies its place in the series of Chinese lunar missions.

QWhy is the far side of the Moon so special?

Often called the "dark side" of the Moon, though inaccurately, as it receives just as much sunlight as the side facing Earth, the far side remains largely unexplored due to communication challenges. It's special because its terrain is rugged with many more craters, providing a unique scientific opportunity to learn about the Moon's history and geology.

QWhat did Chang'e 4 discover?

Among its discoveries, Chang'e 4 found evidence of materials from the lunar mantle on the surface, providing insights into the Moon's geological history. It also conducted radiation and soil composition measurements, offering valuable data for future manned missions to the Moon and beyond.

QCan Chang'e 4 communicate directly with Earth?

No, due to the Moon blocking direct communication with Earth from its far side, Chang'e 4 relies on a relay satellite, Queqiao, positioned in a stable orbit beyond the Moon. This setup allows for a communication link between Chang'e 4 and mission control on Earth.

QHow long was Chang'e 4 expected to operate?

Initially, Chang'e 4 was designed to last for about three Earth months. However, it has far exceeded expectations, continuing its mission and sending back data for several years now, thanks to its robust design and successful management of the harsh lunar environment.

QWhat makes Chang'e 4 different from previous missions to the Moon?

Its landing on the far side of the Moon, an area never before explored up close by humanity, sets Chang'e 4 apart. This unique vantage point allows scientists to study lunar surface features and phenomena not observable from Earth or the near side of the Moon, making its contributions to lunar science particularly significant.
