Chang'e 7

Like its predecessors, the spacecraft is named after the Chinese moon goddess Chang'e. The mission will include an orbiter, a lander, a mini-hopping probe, and a rover.

The Chinese Lunar Exploration Program is designed to be conducted in four phases of incremental technological advancement: The first is simply reaching lunar orbit, a task completed by Chang'e 1 in 2007 and Chang'e 2 in 2010. The second is landing and roving on the Moon, as Chang'e 3 did in 2013 and Chang'e 4 did in 2019 (The rover still being active as of 2023). The third is collecting lunar samples from the near-side and sending them to Earth, a task accomplished by Chang'e 5 in 2020 and to be met by the future Chang'e 6 mission. The fourth phase consists of development of a robotic research station near the Moon's south pole. The program aims to facilitate a crewed lunar landing in the 2030s and possibly build an outpost near the lunar south pole.

The official scientific objectives of Chang'e 7 mission are:

• Investigation and study of lunar surface environment and water ice in its soil.
• High-precision investigation and study of morphology, composition and structure of the Moon.
• Investigation and study of interior structure, magnetic field and thermal characteristics of the Moon.
• General investigation and study of surface environment of the south pole of the Moon.
• Moon-based observation and study of the Earth's magnetotail and plasmasphere.

Chang'e-7 will carry a total of 21 scientific payloads, including 6 international payloads, aiming to conduct detailed exploration of the environment and resources in the south polar region of the moon. Mission objectives include fixed-point landings. In situ observations of the permanently shadowed crater will be made by the mini-hopping probe, which will carry water molecule and hydrogen isotope analyzers.
