China has successfully sent two satellites of BeiDou Navigation Satellite System (BDS) into space from the Xichang Satellite Launch Center in Sichuan Province at 05:10 h on 23 September. Launched on a Long March-3B carrier rocket, the two satellites entered the orbit. They are the 47th and 48th satellites of the BDS satellite family. The new satellites and the carrier rocket were developed by the China Academy of Space Technology and the China Academy of Launch Vehicle Technology, under the China Aerospace Science and Technology Corporation.

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 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.

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.

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.

Two Russo-Chinese agreements on cooperation in lunar research were signed on 17 September 2019 in Saint Petersburg as part of the 24th Meeting of the Russian and Chinese Heads of Government. The documents were signed by Roscosmos Director General Dmitry Rogozin and the Head of China National Space Administration Zhang Kejian. One of the signed agreements is connected with creating and operating a joint Data Center for Lunar and Deep Space Research. The second document deals with the cooperation to coordinate the Russian Luna Resurs-1 spacecraft with the Chinese Chang'e 7 Moon polar research mission.
