Shijian-18 was a Chinese communications and technology demonstration satellite developed and launched by the China Academy of Space Technology on 2 July 2017. It was the maiden flight of the DHF-5 satellite bus, which is designed with 16-year lifespan. Shijian-18 carried 18 experiments on board involving communications and space telescopes.
Shijian-21 [ edit ] In December 2021 - January 2022, China's Shijian-21 space debris mitigation satellite has docked with the defunct Beidou-2 G2 navigation satellite to drastically alter its geostationary orbit, demonstrating capabilities only previously exhibited by the United States.

The code is designed to help scientists and civil protection authorities assess the risk of, and mitigate, hazards due to dry debris flows and avalanches. TITAN2D combines numerical simulations of a flow with digital elevation data of natural terrain supported through a Geographical Information System (GIS) interface such as GRASS .
The first attempt to launch an FSW-0 satellite into orbit on 5 November 1974 failed with the rocket exploding approximately twenty seconds after launch and debris crashing 300 meters from the launch pad. Analysis of the recovered debris led Chinese scientists to blame copper wire damage in the rocket during the second stage. [13] [15]
Debris flows tend to move in a series of pulses, or discrete surges, wherein each pulse or surge has a distinctive head, body and tail. A debris flow in Ladakh, triggered by storms in 2010. It has poor sorting and levees. Steep source catchment is visible in background. Debris-flow deposits are readily recognizable in the field.
He accused Beijing of not doing enough to stop the flow of illicit drugs into the U.S. from Mexico. China's commerce ministry said on Thursday the tariffs would not resolve U.S. internal issues.
Tongxin Jishu Shiyan (TJS, Chinese: 通信技术试验; pinyin: Tōngxìn Jìshù Shìyàn; lit. 'communication technology test') is a Chinese military satellite program operating in geostationary orbit (GEO).
