JIUQUAN, Sept. 19 (Xinhua) -- Five new remote-sensing satellites were sent into planned orbit from the Jiuquan Satellite Launch Center in northwest China's Gobi Desert Thursday.

The five satellites were launched by a Long March-11 carrier rocket at 2:42 p.m. (Beijing Time).

The satellites belong to a commercial remote-sensing satellite constellation project "Zhuhai-1," which will comprise 34 micro-nano satellites, including video, hyperspectral, and high-resolution optical satellites, as well as radar and infrared satellites.

The carrier rocket was developed by the China Academy of Launch Vehicle Technology, and the satellites were produced by the Harbin Institute of Technology and operated by the Zhuhai Orbita Aerospace Science and Technology Co. Ltd.

Thursday's launch was the 311th mission for the Long March series carrier rockets.

The newly launched satellites comprise four hyperspectral satellites with 256 wave-bands and a coverage width of 150 km, and a video satellite with a resolution of 90 centimeters.

The Zhuhai-1 hyperspectral satellites have the highest spatial resolution and the largest coverage width of their type in China.

The data will be used for precise quantitative analysis of vegetation, water and crops, and will provide services for building smart cities, said Orbita, the largest private operator of hyperspectral satellites in orbit.

The company aims to cooperate with government organizations and enterprises to expand the big data satellite services.

Full article can be found at the above link but the gist is below:

China successfully launched a new pair of navigation satellites on Sunday. The launch of Beidou-3M19 (Beidou-47) and Beidou-3M20 (Beidou-48) took place from the LC2 Launch Complex of the Xichang Satellite Launch Center, Sichuan province, using the Long March-3B/YZ-1 (Y65) – Chang Zheng-3B/YZ-1 – launch vehicle. Launch time was 21:10 UTC and it took four hours to complete the mission.

China launched a new meteorological satellite on September 25 using a Long March-2D launch vehicle. Launch of the second Yunhai-1 satellite took place at 00:54 UTC from the LC43/94 Launch Complex of the Jiuquan Satellite Launch Center. This was the fifth Chinese orbital launch in less than a month.

China launched a new remote sensing satellite on Friday, with a Long March 4C lofting Gaofen-10’s replacement.

The launch took place at 18:50 UTC from the LC9 launch complex at the Taiyuan Satellite Launch Center.

The Chinese media is referring to the new satellite as a new remote sensing bird that will be used for “land survey, urban planning, crop yield assessment, and disaster prevention, mitigation and monitoring”.

It is possible that this new satellite might be a direct replacement for the previously lost Gaofen-10 satellite. Gaofen-10 was lost on August 31, 2016 when problems developed with its launch vehicle. The exact nature of that satellite was never disclosed.

Gaofen (“High Resolution”) is a series of civilian Earth observation satellites developed and launched for the state-sponsored program China High-definition Earth Observation System (CHEOS).

a step towards Mars.....



Mars-1 probe consist of an orbiter and a Mars rover. Because of the multitude of missions, the whole payload will be a record setting 5 tons. It will be the most challenging mission yet. Thanks to the foundation laid by the Chang'e lunar program, around 40% of the technology are common with the Mars mission.


Mars-1 probe will make use of seven orbital transfer to travel nearly 300 million km to reach Mars. The signal will be seriously attenuated. Chinese deep space network including the 66 m radio antenna in Jiamusi station, 35 m radio antenna in Kashgar station within the country and other overseas site will provide spacecraft communication support to the Mars mission.

The year 2018 was the busiest one for launches in decades. There were a total of 111 completely successful launches out of 114 attempts. It was the highest total since 1990, when 124 launches were conducted.

China set a new record for launches in 2018. The nation launched 39 times with 38 successes in a year that saw a private Chinese company fail in the country’s first ever orbital launch attempt.

...

The United States was in second place behind China with 34 launches. Traditional leader Russia launched 20 times with one failure. Europe flew eight times with a partial failure, followed by India and Japan with seven and six successful flights, respectively.

I found this image via twitter, in your opinion is this the product of GF geostationary earth observantion satellite? If the answer is yes, i think that chinese can in many circustances attack us carriers in south china sea with asbm and hypersonic weapons without many "kill chain arguments" in between
