11-29-21 At 12:47, China successfully launched the Remote Sensing 31 Group 02 satellite with a Long March 4C carrier rocket from the Jiuquan Satellite Launch Center, and the satellite entered the predetermined orbit. The satellites are mainly used to carry out electromagnetic environment detection and related technology tests.
1-20-21 China successfully conducted the year’s first space launch from
Xichang Satellite Launch Center in SW China’s Sichuan,
The satellite Tiantong 1-03 was launched at by Long March-3B carrier rocket and entered planned orbit successfully.
1-14-21, National Astronomical Observatory Beijing-Arizona BASS survey team and the Dark Energy Spectral Survey DESI International Collaboration Project team jointly released the latest giant two-dimensional sky map of the universe. This is the largest cosmic sky map obtained by human measurement so far. 200 researchers from all over the world have spent 6 years on joint observation and data analysis, covering 20,000 square degrees of the sky, which is about half the area of the whole celestial sphere, accommodating 10 trillion digital pixels and containing 2 billion celestial objects.
China’s hack-proof quantum communication technology is “primarily ready” for practical use after a 4,600km (2,858 mile) network was put through two years of experimental service, researchers announced.
When fully developed, quantum communication can be applied in fields such as finance, defence, government administration and electronic information, according to scientists. This network consisted of the Micius satellite – the world’s first quantum communication satellite launched in 2016 – and more than 700 optical fibres covering 2,000km and connecting 32 nodes across four provinces and three municipalities in China. It was completed in 2017 and has realised communication up to a distance of 4,600km.
China built a high-temperature superconducting maglev train prototype in the SW city of Chengdu. The maglev, which can reach speeds of 620 km per hour, is expected to be the fastest land vehicle.
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.
