A Chinese Long March-4B carrier rocket carrying two environmental monitoring satellites was launched from Taiyuan Satellite Launch Center in north China’s Shanxi Province at 11:23 a.m. Sunday.
China successfully sent the Gaofen-9 04 高分九号04星 high-resolution satellite into orbit on Thursday. Launched by a Long March-2D rocket, the satellite will be used for land survey, city planning, land rights confirmation, disaster prevention and mitigation, among other tasks.
8月6日12时01分，我国在酒泉卫星发射中心用长征二号丁运载火箭，成功将高分九号04星送入预定轨道，发射获得圆满成功。
据了解，这次任务还搭载发射了清华科学卫星。
高分九号04星是一颗光学遥感卫星，地面像元分辨率最高可达亚米级，主要用于国土普查、城市规划、土地确权、路网设计、农作物估产和防灾减灾等领域，可为“一带一路”建设等提供信息保障。
搭载发射的清华科学卫星由清华大学负责研制，将在轨对重力卫星系统设计方法、基于双频GPS的精密轨道大气密度测量方法等理论与技术进行飞行验证。
这次任务是长征系列运载火箭的第342次飞行。
The Space X Starship SN5 prototype completed its first ever 150-meter-high test flight in South Texas, US, on Wed. “Mars is looking real” Elon Musk tweeted after the flight. Looks like a fake, a large empty shell powered by a single engine, it is not carrying any weight.
NASA confirmed that Perseverance slipped into “safe mode” due to an unexpected temperature difference.
“Data indicate the spacecraft had entered a state known as safe mode, likely because a part of the spacecraft was a little colder than expected while Mars 2020 was in Earth’s shadow,” NASA officials said in a statement. “All temperatures are now nominal and the spacecraft is out of Earth’s shadow.”
China sent a new high-resolution mapping satellite into space on Saturday from the Taiyuan Satellite Launch Center in the northern province of Shanxi.
The Ziyuan III 03 资源三号 satellite was launched by a Long March-4B rocket at 11:13 a.m. Beijing time, according to the center. It was the 341st flight mission by the Long March rocket series.
Also on board the rocket were two satellites used for dark matter detection and commercial data acquisition respectively. They were developed by the Shanghai ASES Spaceflight Technology Co. Ltd.
All three satellites have entered preset orbits
China successfully launched its first Mars probe, named Tianwen-1, via a Long March-5 Y4 carrier rocket from Wenchang Space Launch Center in South China’s Hainan Province into planned orbit on Thursday. The move heralds a new era in China’s deep-space exploration, which has steadily progressed beyond moon probes to interplanetary missions, mission commanders and developers said.
After a flight of around 2,000 seconds, the probe entered the planned Earth-Mars transfer orbit, officially embarking on its journey to the Red Planet, according to the China National Space Administration (CNSA)on Thursday.
China’s Tianwen-1 Mars probe is expected to reach Mars’ gravity field in February 2021, about seven months after the launch. If it succeeds, Tianwen-1 will be the first Mars expedition to complete orbiting, landing and roving in a single mission in humanity’s history.

UAE’s Mars probe “Hope”, the first interplanetary Hope Mars Mission in the country and in the Arab world, was successfully launched from a spaceport in Japan on Monday morning. https://www.theguardian.com/science/2020/jul/20/uae-mission-mars-al-amal-hope-space
https://www.yicaiglobal.com/news/galaxyspace-to-build-east-china-super-factory-to-mass-produce-low-cost-satellites New infrastructure greets a boom. Chinese satellite start-up Galaxy Space announced Thursday it will build a satellite mega factory in Nantong, East China’s Jiangsu Province, which will be able to achieve mass production with a relatively low cost, producing one satellite a day.
GalaxySpace, which started operating in 2018, has low-orbit broadband satellite communication technology capabilities. The GalaxySpace Star it successfully launched on Jan. 16 is China’s first low-orbit broadband private communications satellite with a communication capacity of 10 gigabytes per second, and its signals can beam over 300,000 square kilometers.
The launch star of GalaxySpace has verified low-orbit Q/V/Ka and other frequency band communications for the first time in the world, and recently achieved the country’s first low-orbit satellite internet fifth-generation wireless communication network test. The company’s latest value is likely to be over USD1 billion.
China sent a new commercial communication satellite code-named Apstar-6D into planned orbit via a Long March-3B carrier rocket on Thursday. https://spacenews.com/apstar-6d-launches-on-long-march-3b-rocket/
The first satellite for a Chinese company planning a global system of geostationary satellites launched July 9 on a Long March 3B rocket.
Apstar-6D, a high-throughput satellite with a total capacity of 50 gigabits per second, launched at 8:11 a.m. Eastern from China’s Xichang Satellite Launch Center in Sichuan China. China Great Wall Industry Corporation, the arm of China Aerospace Science and Technology Corporation (CASC) tasked with conducting commercial Long March launches, confirmed mission success in a press release after the launch.
