The National Astronomical Observatory installed the 70-meter Mars antenna reflector in Tianjin Wuqing 天津武清 yesterday 4-25-20. The largest single aperture fully movable antenna in Asia, provides a solid foundation for China’s deep space exploration. The high performance receiving antenna with a total weight of about 2,700 tons, 72 meters high, the diameter of the main reflecting surface is 70 meter, composed of 16 laps of 1328 high-precision panels, has an area equivalent to nine basketball courts.
As many satellite startups plan to launch small satellites into low-Earth orbit (LEO) to provide global broadband internet services, a Chinese satellite provider now suggests the use of 5G speeds for the purpose.
The call comes as China attaches more importance to the development of the satellite-enabled mobile internet and includes the area in its “new infrastructure” construction plan, which could offer both short-term relief and a long-term boost to the economy.
Beijing-based private aerospace company Galaxy Space recently held an experimental 3-minute video call by connecting to Wi-Fi hotspots provided by a satellite terminal. Galaxy Space launched China’s first LEO 5G broadband satellite that went into orbit earlier this year.
The clear picture and swift response in the video call on Friday proved that the LEO 5G broadband satellite developed by the private startup is reliable, while a race between the world’s top economic superpowers to roll out 5G networks goes on.
The National Development and Reform Commission included the satellite internet into the “new infrastructure” list on April 20, ramping up its efforts to develop the technology.

This week, China will officially launch a major new blockchain initiative called the Blockchain-based Services Network (BSN). The BSN is a critical part of China’s national blockchain strategy that was announced by President Xi in late November 2019, but went largely under the radar as the simultaneous announcement of China’s digital RMB currency, called the DCEP, swept the world by storm. Only recently has the Western media recognized the significance of the BSN, which sees its mainland commercial launch April 25. The portal’s global commercial launch is scheduled for June 25.
Huawei will reportedly launch on April 24 a new DC fast-charging module product, which will act as a solution to NEV charging infrastructures.
The upcoming solution, dubbed “Huawei HiCharger”, has partnered with several Chinese companies, such as State Grid, Star Charge, China Southern Power Grid Electric Vehicle Service Co.,Ltd., Huashang Sanyou, Titans as well as Dalian Luobinsen, according to a local media outlet. The release of HiCharger signals Huawei’s beginning of the offensive into NEV charging domain. The leading smart device supplier has repeated in the public its ambition to be a core “increment parts” supplier for intelligent-connected vehicle (ICV) rather than a car manufacturer.
Although China’s bearing industry has developed rapidly for many years, it has now become the third largest bearing country in the world in terms of bearing output and sales, but the key technology areas still need to be strengthened, especially the gap between the aerospace bearing technology and the first bearing is obvious. It is speculated that hybrid ceramic bearings have been initially applied in the field of China’s new turbofan 15 aero engine and transmission.
Scientists in southwest China on Tuesday said they had built the world’s second biggest solar telescope, which they say will provide more accurate data and improve forecasting.
With a 1.8-metre aperture, the Chinese Large Solar Telescope (CLST) was developed by the Institute of Optics and Electronics at the Chinese Academy of Sciences in Chengdu, Sichuan province.
Supercapacitors can charge almost instantly, and discharge enormous amounts of power if needed. They could completely erase the Achilles heel of electric vehicles – their slow charging times – if they could hold more energy. And now Chinese and British scientists say they’ve figured out a way to store 10 times more energy per volume than previous supercapacitors.
A team split between University College London and the Chinese Academy of Sciences has released a study and proof of concept of a new supercapacitor design using graphene laminate films and concentrating on the spacing between the layers, the researchers discovering that they could radically boost energy density when they tailored the sizes of pores in the membranes precisely to the size of electrolyte ions.
Using this design, the team says it’s achieved a massive increase in volumetric energy density. Where “similar fast-charging commercial technology” tends to offer around 5-8 watt-hours per liter, this new design has been tested at a record 88.1 Wh/l. The team claims it’s “the highest ever reported energy density for carbon-based supercapacitors.”
The world’s first large, three-engine utility drone recently made its first flight. Developed by Chengdu-based Tengden Technology Co, the drone is a three-engine variant of Tengden’s twin-engine TB Twin-tailed Scorpion, as this design is a world first for drones. The drone has a width of 20 meters and a length of 11 meters. It is equipped with three piston engines, with one under each wing and one on its tail, enabling it to have a maximum takeoff weight of 3.2 tons and an endurance of 35 hours.The drone has a flight ceiling of 9,500 meters, a max climb rate of 10 meters a second and a top speed of more than 300 kilometers an hour.
China has finished building the world’s most powerful ion thruster and will soon use it to improve the mobility and lifespan of its space assets, according to a state media report this week.
Researchers at the 502 research institute, which operates under the China Aerospace Science and Technology Corp. in Beijing, have delivered a new-generation Hall-effect thruster unit to Chinese customers in the space industry, the report by the Science and Technology Daily stated.
The machine will outperform all of the ion thrusters used on satellites or spacecraft that are currently in use, it added. The daily is run by the Ministry of Science and Technology.
A self-elevating wind turbine installation vessel has been delivered Thursday to a subsidiary of China Communications Construction Company.
The vessel, developed by Shanghai Zhenhua Heavy Industries Co., Ltd., integrates multiple functions such as large equipment hoisting, installation and transportation.
It is 90 meters long and 40.8 meters wide. With a deck area of 2,400 square meters and a variable load of around 3,200 tonnes, the ship can accommodate three six-megawatt wind turbines or two eight-megawatt wind turbines.
