The Korea Superconducting Tokamak Advanced Research or KSTAR has taken a major leap forward in the development of a working nuclear fusion reactor. Unlocking the power of nuclear fusion has been the dream of scientists since the early 20th century but has proven a tough puzzle to crack. Nuclear fusion, which works by combining two atomic nuclei into a larger nucleus to release energy, promises to unleash more energy than it consumes.
China’s first independently-developed 3.2-meter three-segment solid rocket motor for civil space completed its first ground test in Xi’an, Northwest China’s Shaanxi Province on Wednesday, marking China’s largest and the most powerful segment-type solid rocket engine tested to date. The segmental solid rocket buster is a solid fuel rocket engine divided into several sections and each section has its own shell, adiabatic structure and propellant charge column.
The engine can be applied to large & heavy rockets to meet the needs of space equipment, manned moon landing & space exploration.
China successfully launched remote-sensing satellite No. 33 on a Long March 4C carrier rocket from the Jiuquan Satellite Launch Center in Northwest China late Sunday. The mission also launched a micro-nano technology test satellite.
Scientists in NE China’s Liaoning made a breakthrough on low temperature plasma disinfection technology amid a rise in imported cold chain food threats. Lab tests show 99.99% of the COVID19 virus is eliminated.
12-26-20 The world’s strongest nuclear astrophysical accelerator was initiated in the deepest underground laboratory in the world, 2,400 meters underground, in Jinping, China on Saturday.
China has completed the world’s largest ultra-low coal-fired power plant emssions system, with coal consumption in energy mix dropping to 57.7%, according to Ministry of Ecology and Environment.
China’s new generation medium-sized launch vehicle Long March-8 made a successful maiden flight from the tropical island province of Hainan in South China on Tuesday, sending five satellites into designated orbit at the same time.
The 50.3-meter-long Long March-8 has a 3.35-meter-diameter core stage and two 2.25-meter-diameter side boosters. Weighing 356 tons at launch, it has a 480-ton take-off thrust and is capable of sending payloads weighing more than 4.5 tons into the SSO 700 kilometers above the ground.
A rocket engine needs to be throttleable to achieve zero velocity at the same time as it reaches the ground, which is a core technological requirement for building a reusable launch vehicle system.
This technology was tested for the first time in the Long March-8 maiden flight, which is also an experimental flight for the new rocket type, paving the way for further study and development for the reusable rocket system.
Construction has begun of the world’s first 100,000-tonne fish farming ship in Qingdao, E. China’s Shandong Province on Sat, pioneering a new mode of intelligent industrial fish farming in distant seas.
