Hualong One nuclear power plant put into commercial operation
Unit 5 of China’s Fuqing Nuclear Power Plant, the world’s first Hualong One nuclear power plant was put into commercial operation on Saturday using China’s Hualong One third-generation nuclear power technology.
Remote Sensing 31 Group 02 satellite
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.
The largest two-dimensional map of the universe ever released, including 2 billion objects
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 quantum communication network
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.
High-temperature superconducting maglev train prototype
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.
South Korean artificial sun sets world record, runs for 20 seconds at 100 million degrees
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.
Three-segment solid rocket booster
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.
Remote-sensing satellite No. 33
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.
