China's Space Program Thread II
- Thread starter Blitzo
- Start date
Galactic Energy has successfully completed a cold flow test on the second stage liquid oxygen delivery system of the Pallas-1 reusable rocket.
Looks like a grave wtf…
I'm skeptical that launch sites on a mountainous and overcrowded island are a good idea in any case.

Some updates on the Hainan Commercial Spaceport.
1) Current progress on the launchpad no. 2 (in the back ground you can see the completed launchpad no. 1):
2) Roof trusses for the Sanping test complex are being installed. The exterior structure should be finished by the end of this month, with focus quickly turning to finishing the interior:
3) Hainan Commercial Spaceport's propellant supply infrastructure project has broken ground. Once finished, it will supply the spaceport with six types of propellants: liquid oxygen, hydrogen, nitrogen, methane, helium, and kerosene:

The first steel beam for the Sanping test complex at the Hainan Commercial Spaceport has been hoisted. Once finished, the complex will occupy some 29 acres and be home to various facilities used to conduct final testing on satellites and then integrate them to launch vehicles. The complex will also host other auxiliary buildings for power generation/distribution and equipment storage.

Some illustrations from a describing a proposal for an astroid defense system. The paper is part of a special issue, which you can .
A brief summary of the proposal:
Upon detecting a threatening astroid via ground based observation, an impactor and an observer satellite are launched together toward the target. The observer satellite arrives first and performs a detailed study of the target astroid, including taking topographical 3D scans and measuring its material composition and orbit. The impactor arrives later at the target and autonomously sets itself on an impact course. The observer satellite records the impact process and again takes detailed measurements of the astroid post impact and then compares the latest measurements with previously recorded data to assess whether the impact has sufficiently altered the astroid's path. The advantage of the proposal is that it eliminates the limitations of ground-based observation on assessing the effectiveness of an impact.
Excerpts from an academic paper (小行星防御试验任务科学目标设计与有效载荷配置/Asteroid Defense Test Mission Scientific Target Design and Payload Configuration). China plans to carry out a technology verification test of the asteroid defense system currently under development, and asteroid 2015 XF261 has been selected as a promising target. The test is expected before 2030.

i-Space/Interstellar Glory will an engine production and rocket assembly base in Anqing, Anhui province. The project will cost ¥5 billion and will occupy more than 400 acres. Once completed, it will have the capacity to produce 20 launch vehicles annually.

An update on the 130-ton YF-100N LOX/Kerosene reusable engine. The engine has accumulated more than 3900 seconds in hot test runs, during which it completed 30 ignitions (15 restarts).
The pace of testing on the YF-100N engine (for the Long March 10 moon rocket) is being stepped up. Only seven days after its last full test run (with restarts), another –– and the 16th overall –– was carried out successfully.
