Mission description
Queqiao-2 is a Chinese artificial satellite to serve as a communications relay for future Chinese lunar far side missions that cannot communicate directly with the Earth, beginning with the Chang'e 6 lunar sample return mission in 2024. It will operate from a Distant Retrograde Orbit (DRO) of the Moon. The launch also carries the Tiandu-1 & 2 small satellites testing cis-lunar space navigation and inter-satellite communication techniques for CNSA’s Deep Space Exploration Laboratory (DSEL).
