Taiji 1 space-based gravitational wave detection test satellite
20 September 2019
Taiji 1 satellite, launched on 31 August, has conducted in-orbit experiments on the key technologies related to space-based gravitational wave detection, the Chinese Academy of Sciences (CAS) announced on 20 September. The satellite is China's first such kind of satellite, and has completed its first stage tests in orbit, laying a solid foundation for future gravitational wave observation in space, said Xiangli Bin, vice president of CAS. "This is the first step of China's space-based gravitational wave detection. But there is still a long way to go to realize detecting gravitational waves in space. Chinese scientists will continue to contribute Chinese wisdom to the exploration and human progress," Xiangli said.

Chinese researchers conduct in situ measurement of lunar dust at Chang'e-3 landing site
20 September 2019
Chinese researchers have successfully conducted an in situ measurement of lunar dust at the landing site of the country's Chang'e 3 probe. Using a temperature-controlled sticky quartz crystal microbalance onboard the Chang'e 3 lander, researchers from the Lanzhou Institute of Physics determined that the total deposition mass at a height of 190 cm above the lunar surface during 12 lunar daytimes in the northern Mare Imbrium was about 0.0065 mg/cm2.

Chinese quantum satellite used to test basic theory in physics
20 September 2019
An international team led by Chinese scientists used the Micius quantum satellite to test why quantum mechanics and the general theory of relativity, two bedrocks in modern physics, don't work together. The study published on 19 September online in the journal Science partially ruled out a hypothesis that the entangled particles would decorrelate from one another as they passed through separate gravitational regions of Earth.

China launches five new remote-sensing satellites
19 September 2019
Five new remote-sensing satellites were sent into planned orbit from the Jiuquan Satellite Launch Center in northwest China's Gobi Desert on 19 September. The five satellites were launched by a Long March-11 carrier rocket at 14:42 h (Beijing Time). The satellites belong to a commercial remote-sensing satellite constellation project "Zhuhai-1," which will comprise 34 micro-nano satellites, including video, hyperspectral, and high-resolution optical satellites, as well as radar and infrared satellites.
