Queqiao 2
Queqiao 2 []
Queqiao 2 is a Chinese relay satellite mission in support of the Chang'e 6, 7 and 8 lunar landing missons.
It is a larger, heavier, more capable version of Queqiao-1. The about 1200 kg relay satellite is based on the three-axis stabilized CAST-2000 small satellite bus featuring an 130 N hydrazine propulsion system. It carries a deployable 4.2 m dish antenna for the relay equipment. It provides four 256 kBps X-band links between itself and the lander/rover and one 2 MBps S-band link towards earth.
Besides the relay function, the spacecraft also carries some science payloads:
- Extreme ultraviolet camera
- array neutral atom imager
- Earth-Moon VLBI system
The mission is to be launched in 2024 on a CZ-8 (1).
