A closer and better view of #ZK1A's liftoff. It would be better without the music..

Some photos of the transportation & assembly of #ZK1A. CAS Space is China's first commercial launch provider who has its own launch facility in operation.

Look the lower left of this photo. There's another #ZK1A on site, but I guess it should be the pathfinder.

Of the 6 payload on board, 5 are built by CAS’ Shanghai Engineering Center for Microsatellites, with a 6th (“Southern Guangdong Scientific Satellite”, TBC) from SAST probing soil moisture & ocean surface wind.

时隔 6 年,中国第二颗量子通信卫星成功发射升空

After 6 years, China's second quantum communication satellite was successfully launched into space

At 12:12 on July 27, the world's first quantum micro-nano satellite "Jinan-1" was successfully launched on the "Lijian-1" carrier rocket at the Jiuquan Satellite Launch Center. At present, "Jinan No. 1" has entered the established orbit, the solar panel has been successfully opened, and the on-orbit test work will be carried out soon. The successful development of the "Jinan No. 1" quantum micro-nano satellite will enable my country to realize real-time satellite-to-ground quantum key distribution between micro-nano satellites and miniaturized ground stations for the first time in the world, and build a low-cost and practical space-earth integration Quantum secure communication network.

The "Jinan No. 1" micro-nano quantum satellite was led by Hefei National Laboratory, and was jointly developed by the University of Science and Technology of China, the Jinan Institute of Quantum Technology, the Institute of Microsatellite Innovation of the Chinese Academy of Sciences, and the Shanghai Institute of Technical Physics. With the support of the Jinan High-tech Zone Management Committee, the Jinan Institute of Quantum Technology is responsible for organizing the development of ground application systems, and as a user, it conducts the overall verification of quantum key distribution application technology.

The "Jinan-1" quantum micro-nano satellite is the second quantum communication satellite launched by China after the launch of the "Mozi" quantum science experimental satellite in 2016. Based on the research and development and experiments of the "Mozi" quantum science experimental satellite, the research team successfully tackled key technologies such as low-cost miniaturized quantum key distribution technology, real-time key extraction technology, etc. The nano-satellite platform is developed to reduce the weight to about 1/6 of the Micius, increase the frequency of the light source by about 6 times, and improve the timeliness of key generation by 2-3 orders of magnitude. With the miniaturized ground station system, real-time satellite-to-earth quantum can be completed. Key distribution experiment, and carry out technical verification and application promotion.

The successful launch and in-orbit operation of the "Jinan No. 1" quantum micro-nano satellite will be followed by a demonstration of commercialized wide-area quantum communication network applications through a miniaturized satellite ground station in Jinan, which will help my country expand its international presence in the field of space quantum communication. Leading position, realizing the leap-forward improvement of national information security and information technology level.

At 1:40 on August 16, 2016, my country successfully launched the world's first quantum science experimental satellite "Mozi" with the Long March 2D carrier rocket at the Jiuquan Satellite Launch Center. Then humans completed quantum communication between satellites and the ground for the first time.
The Diguidao Liangzi Mishifenfa Shiyan (低轨道量子密钥分发试验) is also named Jinan-1 (济南一号).

SAST (Shanghai Academy of Spaceflight Technology) logo is very similar to SpaceX logo.

Yet this is another SAST.

The stack of satellites that were launched on July 27 - all but SATech-01 are Chinese Academy of Sciences payloads.

All but F, the GNSS-R..

China Focus: Chinese scientists detect brightest gamma-ray burst to date
Source: Xinhua Editor: huaxia 2022-10-19 16:05:00
BEIJING, Oct. 19 (Xinhua) -- Chinese scientists have detected the brightest gamma-ray burst (GRB) to date through combined observations from both Earth and space, according to the Institute of High Energy Physics (IHEP) of the Chinese Academy of Sciences.
The combined observations were made on Oct. 9, 2022, by China's Large High Altitude Air Shower Observatory (LHAASO), the High Energy Burst Searcher (HEBS) -- an all-sky monitor for gamma-ray transients -- as well as China's X-ray astronomy satellite Insight-HXMT (Hard X-ray Modulation Telescope), achieving multi-spectral measurements of the gamma-ray burst, coded as GRB 221009A.

[👀Must-watch] ~1 month after the maiden launch of #ZK1A 力箭一号, CAS released an impressive documentary that includes every key moment of a rocket launch. Great thanks, CAS, though it's not a live stream.
Note: I made some cuts for this short
