intro

1.Long March 8 (code: CZ-8) is a new generation of medium medium and low orbit two-stage liquid-strapped carrier rocket developed by China.

2.The first stage of Long March 8 rocket uses liquid oxygen/kerosene as propellant and two YF-100 engines with 120 tons thrust. The second sub-stage uses liquid hydrogen/liquid oxygen as propellant and two 8-ton thrust YF-75 engines with secondary starting capability; two bundling 2. 25 m diameter liquid boosters, liquid oxygen/kerosene as propellant, each using a 120-ton thrust YF-100 engine. Total length of rocket: 50. 3m, core primary diameter 3. 35 m, secondary diameter 3 m, single booster diameter 2. The rocket, which has a take-off mass of about 356 tons, is mainly used to launch low-earth orbit or sun-synchronous orbit payload, and can send a payload of 5 tons to 700km sun-synchronous orbit.

1.Queqiao 2 (English: Queqiao-2), a relay communications satellite developed and launched by China.

2.Queqiao 2 relay communications satellite weighs 1. 2. 2 tons, equipped with a diameter of 4. Two meters of X-band parabolic antenna, used to communicate with probes landing on the far side of the moon, and a diameter of 0. 6 m S/Ka dual-band parabolic antenna for data transmission to the ground station. The satellite mainly provides a public relay platform for China 's Phase IV lunar exploration project to carry out lunar sample collection missions on the far side of the moon. Provide relay support for four Chang'e-4, Chang'e-6, Chang'e-7 and Chang'e-8 missions.
