Все чутка проще, это пока(?) не реюз. Видео я так понял не сегодняшнее, а с 27 июня. Надо будет дождаться нормальной статьи на НСФ.

In recent years, with the launch of high-density density of launch vehicles, reports of "rockety wreckage falling into villages" have appeared from time to time, and the safety of rocket wreckage has received widespread attention. Due to the development of society and the increase in population, the rocket wreckage area built around the inland launch site in the 1960s and 1970s is no longer an absolute no-man's land. Although the rocket's flight path is accurately calculated, it will try to avoid the villages and towns. However, since the rocket wreckage is uncontrolled and re-entered after completing the mission, the distribution of the landing point is large, and sometimes it may involve an inhabited area. In order to ensure the safety of personnel, the people in the area must be evacuated to a safe place, which not only brings inconvenience to the local people, but also increases the economic cost and difficulty of the rocket launch.

According to Yang Jianmin, chief designer of the Chang'an 2nd C-launch rocket of the First Aerospace Science and Technology Group of China, in order to reduce the inconvenience caused by rocket launching to the people in the area, the first design department of the hospital has been working on the controllable recycling technology of separated bodies. A re-entry fixed point recovery scheme based on grid rudder and wing-based umbrella is proposed. The fairing of the Long March II C rocket was accurately recovered through the technical solution based on the wing umbrella, which laid a solid foundation for the controllable recycling, soft landing and re-use of the launch vehicle booster and sub-class.

The reporter learned that this technology is the first engineering application in China. Firstly, through the separation and re-entry monitoring system, the attitude and video data of the re-entry reentry process are obtained, and then the parachute-based rectification is verified by the parachute homing system. The cover is accurately recycled. Follow-up China will also carry out tests on the recovery of the booster based on the parafoil, providing solutions for future reusable technologies.

According to Xu Lijie, a rocket designer, the development team boldly adopted commercial-grade components and structural parts processed by private enterprises. The reliability was ensured by dual-mode redundant design and sufficient ground test. It took only 2 months to complete. The entire process of design, production and testing of “Yuyan No.1”. On June 27th, the team completed the development and verification of the first step separation and reentry monitoring system, successfully obtained the high-definition video data of the fairing reentry process, and obtained the re-entry posture and re-entry ballistics through analysis and calculation. Information such as aerodynamic characteristics provides an important basis for calculating the parachute height and opening attitude of the parasol system. This is the first time that China Aerospace has obtained video data on the re-entry process of the separation.

(1) On October 26, the CZ 4B carrier rocket launched the Ocean 2B satellite at the TSLC;
(2) October 27, China's Blue Arrow Space Company Zhuque-1 (ZQ-1, LandSpace-1, LS-1) solid carrier rocket launched the "Future" satellite into the orbit;
(3) October 29, the CZ-2C carrier rocket launched the China-French Marine Satellite (CFOSAT) at the JSLC;
(4) October 31 (no responsibility, guess, don't spray), CZ-3B launches Beidou II navigation system backup star at XSLC. (At present, it is uncertain whether it is Beidou III or Beidou II, and it is not sure whether it is GEO or IGSO)
(5) On November 20, CZ-3B launched the Beidou No. 3 navigation system double star M17 and M18 at the XSLC; (At this point, the Beidou constellation completed the mission in 2018).
(6) November 25, KZ-1A has a launch in Jiuquan.
(7) Before the end of November, Saudi Double Star (SaudiSat-5A and -5B, CZ-2D)
(8) December 8, Xichang 嫦娥 4 launch (Chang'e 4 CZ-3B) (multiple channels confirmed the launch date, high credibility)
(9) December 25th, Xichang CZ-3B, high-probability communication satellite Zhongxing 6C (ZX 6C/ChinaSat 6C) (from the space enthusiast network), Xichang 2018 ending, a total of 17 launches, I drop a day ...... The original time to shoot the head is December 15th, but according to the time interval between the two launching modes of the two launchers in Xichang, it is considered that after the No. 8 hit the No. 4, it is difficult to launch the follow-up mission on the 15th. For a time interval of 17 days, the head is set at 25th.
(10) December 15, Taiyuan Resources No. 1 02D (from Aerospace enthusiasts) (CZ-4B Ziyuan-1 04?)
(11) December 29, Jiuquan closed, the load is unknown

The above total is 11 rounds, plus 28 rounds have been launched, a total of 39 rounds. Broken 40 is still very promising!

In the remaining 70 days of 2018, in addition to the above statistics, it is possible to launch:
1 CZ 11 first flight
2 Lightning Dragon-1’ (Jie Long-1, LD-1 Chinarocket Co.) first flight
3 GF-7
4 small solids in zero space
