It might be a bit premature for private cargo services to the Chinese space station, but then again, maybe I'm wrong. What do others think?

Eventually, it has to go to private companies. If you make the commercial satellite launch space of your country open to private companies, sooner they will become reliable enough and cheap for some components of National space missions. Cargo supplies is one such area of overlap.

National resources are better devoted to novelty and high technology / science endeavors.

I would be bolder to say a lot premature. I will give at least 5 years before they can deliver the same payload with the same reliability as CZ rockets for a competitive price. The reason I say so is because so far after years development, there is only one entering LEO (300kg) followed by two failures of the very same rocket (Hyperbola-1).

I don't object non-state players to compete, but looking from their current state and past performance, another 5 years is a realistic estimation for any meaningful payload (many tonnes) into LEO. CSS is not something that can be risked, so another 2 or 3 years of continuous success would be needed to allow the rocket to do the job. Also the cargo spacecraft and docking device must be developed if not using Tianzhou. All these put together, I would say 10 years. Just look at how long time does it take SpaceX to dock their spacecraft to ISS with Falcon 9.

Problem with the private space companies in China is that the big players with actual capital are unwilling to invest.

The capitals in China are not specifically interested in space industry which is very risky investment compared with other areas. This is natural.

If we look at US, Blue Origin and SpaceX are different that their founders have a deep pocket and they are devoted in the business, they make up a big portion of the investment. Another big difference is that NASA relies on (old) private companies for its rocket, even SLS and Space Shuttle are made by private companies. NASA and the air-force have the incentive to break monopoly of the old players (price negotiation) by guaranteeing some contracts to new players, essentially NASA the state is paying for the risks. Look back at China, CNSA and PLA directly control CASC and CASIC who do not have the right to negotiate price, so CNSA and PLA do not need to bring up competition therefor no investment to the private sectors.

In a way, the Chinese private space companies are REAL private, the American companies even SpaceX is semi-state with state subsidies and guarantees.

The joke in Silicon Valley has been rockets are a great way to make a small fortune...from a large one. I can imagine this is echoed in China.

508 Institute of the 5th Academy of CASC has successfully completed a preliminary parachute drop test for the next generation crewed spacecraft. The test was conducted to verify results obtained from wind tunnel testing of an improved parachute design. Further drop tests on full-size parachutes will be carried out in the future.

近日,中国航天科技集团有限公司五院508所新一代载人飞船缩比群伞空投试验顺利完成并取得圆满成功。该试验的主要目的是通过多架次空投的迭代验证来评估风洞试验后优选的改进伞型效果,从而为后续开展全尺寸降落伞性能空投试验奠定技术基础。

本次新飞船空投试验共进行了包含预试验在内的共11个架次的投放试验,由直升机携带航弹模型飞行至预定高度,以预定速度到达预定区域后进行投放,模型按照程序开始工作,稳定伞脱离,群伞同步开伞,直至模型落地。同时,模型内安装的测量和控制设备进行数据测量和记录。

本次空投试验充分验证了优化改进设计的降落伞组成群伞的工作性能,为后续开展全尺寸降落伞性能空投试验奠定了扎实的基础。

The airdrop test of the 508 new generation manned spacecraft of the 5th Academy of Aerospace Science and Technology achieved a complete success


Recently, China Aerospace Science and Technology Corporation Fifth Academy 508 of the new generation manned spacecraft downscale group parachute airdrop test successfully completed and achieved complete success. The main purpose of the test is to evaluate the effect of the optimized umbrella shape after the wind tunnel test through the iterative verification of multiple airdrops, so as to lay the technical foundation for the subsequent full-size parachute performance airdrop test.

In this new spacecraft airdrop test, a total of 11 sorties including pre-tests were carried out. The helicopter flew the air bomb model to a predetermined height, reached the predetermined area at a predetermined speed, and then launched the model. The model began to work in accordance with the procedures. The stable umbrella is separated, and the group umbrellas are opened synchronously until the model falls to the ground. At the same time, the measurement and control equipment installed in the model performs data measurement and recording.

This airdrop test fully verified the working performance of the optimized and improved parachute group parachute, and laid a solid foundation for the subsequent full-size parachute performance airdrop test.
