Yea, basically filling rockets with solid propellant is quite hard, a hassle, slow, dangerous and costs quite a lot.
But well, China was able to make some machine so that it can fill DF-17 size missiles with solid propellant like how sausages are made, cutting costs by A LOT and making it safer and faster.
Chinese MSM revealed one more hypersonic research project, the "whistling arrow" multiple speed domain flight vehicle (“鸣镝”宽域飞行器).
The project team, with the honorary title that is named after the venerable Chinese scientist Qian Xueshen (钱学森), has successfully completed 7 flight tests in 5 areas, including "near-space drop release of high speed flight vehicle" (临近空间投放高速飞行器实验) and "international multi-speed domain round-trip flight" (国际宽域飞行器返场实验).
[We have seen this photo before. In this test in 2018, a balloon released models of multi-speed domain flight vehicle in different aerodynamic configurations. This might be the "near space drop release" test mentioned above.]
The team has made breakthroughs in key ares of multi-speed domain flight. A first in the country, they created the "near-space drop release" test model. Their visionary work in multi-speed domain flight and reusable technologies enabled to solve the all-speed domain adaptability problem of near-space hypersonic flight (临近空间高超声速飞行全速域适应性难题).
"宽(速)域飞行器", or multi-speed domain flight vehicles [does anyone have a better translation of it?], are different from any of the existing flight vehicles in that such a vehicle will need to fly in multiple speed domains, including subsonic, transonic, supersonic and hypersonic speeds, and maintain stable and full control of the flight during the course. Tengyun (腾云) will be a typical multi-speed domain flight vehicle.
This is a team of mostly younger scientists. The leader, Li Wenhao (李文皓) a graduate from Northwestern Polytechnical University, himself was born in the 80s. Among the 32 team members, 65% are only 35 years old or younger.

An extremely bright future for China in developing any deadly weapons to protect its territory. They are young, talented, innovative and they love their country. As an example: the teams that develop China's heavy lift rockets, the Tiangong Space Station, bullet trains and infrastructure, ship building and so on...
Damn clickbait
it is a study of using Beidou’s communication capabilities
SCMP ”journalists” have no morals
| In order to solve the uninterrupted space⁃based communication problem in the world，the communication efficiency of the existing space⁃based communication support system in China is analyzed.BeiDou Navigation Satellites has the advantage of global coverage， which can provide all⁃weather and all⁃day TT&C(Tracking Telemetering and Command)， navigation and communication sevices. Based on the application background of BDS ISL(Inter⁃Satellite Link system)，STK(System Toolkit) simulation models are established for three typical application scenarios， the global coverage in three scenarios are analyzed. The simulation results show that the satellite forwarding mode can meet the global uninterrupted communication guarantee，and the communication efficiency can meet the communication requirements of short message and voice. A reasonable and feasible star cutting scheme is given for the communication link interruption problem that may occur when the attitude adjustment of highly maneuvering near space vehicles is too large. The task timeliness of BDS ISL system are theoretically calculated and analyzed. |

why is the glider's belly facing sideways as opposed to facing forward? Or am I seeing things wrong in such a distance?A still screenshot.
Good stuff! Don't say we haven't warned you.
