China's Space Program Thread II

CNSA/DSEL: Two small satellites, 61 kg Tiandu-1 and 15 kg Tiandu-2, will be launched together with Queqiao-2 in 2024 to test technologies for a future lunar navigation and positioning constellation..

Queqiao-2 with Tiandu-1 and Tiandu-2 will be launched by Long March 8 in 2024. The new commercial launch pad currently under construction in Wenchang should be ready by then..

now this mission extended to next level. insane

CNSA plans to make Queqiao an international asset of planetary comm., navigation & remote sensing constellation & calls for global proposals:-

1. 50Mbps earth-moon communication & 100m positioning
2. 1~10Gbps & 50m, full lunar coverage
3. 10Gbps & 10m, Mars Venus & solar system

The above goals by 2030, 2040 and 2050 respectively.

The launch of Gravity-1 will take place by the end of 2023.

I didn't follow this company very carefully. Is the short rocket (1st photo) solid? At least the boosters look like solid. The long rocket (right side of the last photo) seems to have liquid core with solid boosters.

All stages are solid, made by CASC's solid booster department. From what I heard (not confirmed), the core and booster stage are 2.65m in diameter, CASC's generic design.

The long rocket has a kerelox core stage, and two solid boosters.

May I ask if you have entered the wrong data？ Because the date on the PPT is around 2030.

yes. that was a typing error.

ZHANG Rongqiao: "Tianwen-3 Mars sample return & Tianwen-4 are very challenging. We expect 2/3 more years to make breakthroughs of the key technologies." Both planned for 2030. The latter includes flybys of Venus, Earth before orbiting Jupiter & Callisto & a separate Uranus probe

official Timeline of Tianwen-4:-

2030 launch
2035 orbiter arrives at Jupiter and Callisto
2046 Uranus flyby

Gravity-1 is all solid. Not sure about Gravity-2, which is the longer rocket, but it doesn't look like it.

From the look YL-2 and YL-3 having landing legs the core and common cores are liquid. @Kalec has also pointed that out.

The core stage consists of seven YL-85 engine, which uses LOX / RP-1, with a vacuum thrust of 85 tons and a sea-level thrust of 70 tons, a vacuum specific impulse of 325s and a sea-level specific impulse of 278s, a thrust adjustment range of 50%-110%, a thrust-to-weight ratio of 115, and a gas generator cycle.

Basically a YF-102? I wouldn't be surprised that it is just a variant of YF-102 tbh.

A satellite jointly developed by China and Egypt, called Egypt-2 (埃及二号), is undergoing final assembly at the Egyptian Satellite Assembly Integration Test Center (AITC) located in New Cairo, Egypt. Both the Egypt-2 and the AITC were part of a

Chang'e-6 lunar sample return mission is planned to be launched in May 2024. I will take a sample in the area located at 43º (±2º) S, 154º (±4º) W on the far side of the moon, just southwest of the Apollo crater (see circled area in 2nd image).
