Change 6 is Chinas second lunar soil sample return mission similar to Change 5 which launched in late 2020. China is set to launch a first ever attempt to collect samples from the far side of the Moon. Launch is currently expected in May 2024, with a relay satellite set to fly in the preceding months to support the mission.This mission aims to grab samples containing material ejected from the lunar mantle and thus provide insight into the history of the Moon, Earth, and Solar System.The mission is a more ambitious followup to China's Chang'e-5 2020 sample return mission.The mission will attempt to obtain the first-ever soil and rock samples from the lunar far side and return it to the Earth.The primary phase of the mission is expected to last about 53 days.Like its predecessors, the spacecraft is named after the Chinese moon goddess Chang'e.
