China's first high orbit remote sensing satellite, Gaofen-4, was sent into space Tuesday. Gaofen-4 is China's first geosynchronous orbit high-definition optical imaging satellite. It will be used for high-precision observation of China and its surrounding areas, and serving as the source of observation data.
Chinese researchers say H1N1 swine flu viruses, which have circulated in pig populations since 1979, have obtained the ability to infect humans and may "pose the highest pandemic threat" among flu viruses currently in the animal population.
Although collider programs proposed by different countries are always fiercely competitive and can be highly nationalistic in flavor, the whiff of gunpowder is much fainter among physicists working on neutrino projects.
China on Tuesday launched its most sophisticated observation satellite, Gaofen-4, as part of the country's high-definition (HD) earth observation project. Gaofen-4 is China's first geosynchronous orbit HD optical imaging satellite and the world's most sophisticated HD geosynchronous orbit remote sensing satellite, according to Xu Dazhe, head of SASTIND and China National Space Administration.
A trial run of China's first domestically designed and manufactured magnetic levitation line in Changsha, Hunan Province, began on Saturday. The maglev line uses "Zhuifengzhe" (wind chaser) trains designed and manufactured by railway manufacturing giant CRRC in Hunan's Zhuzhou.
A new type of basaltic rock, discovered by Chinese moon rover Yutu (Jade Rabbit) during an unmanned lunar exploration mission, may help shed light on lunar volcanism. The rock was sampled at a fresh crater called Zi Wei, a landing site of Chang'e-3, which reached the moon with the rover in December 2013.
