China has successfully launched two environmental monitoring satellites from the Taiyuan Satellite Launch Centre in northern Shanxi Province on 27 September. A Long March-4B rocket carrying the HJ-2A and HJ-2B satellites took off at 11:23 BJT, according to the launch centre.
They will replace the HJ-1A and HJ-1B, the previous generation of environmental monitoring satellites, to provide services concerning environmental protection, natural resources, water conservancy, agriculture and forestry, according to CAST - the satellite developer.

The Chang'e-4 lunar lander touched down on the far side of the Moon on 3 January 2019, with a German instrument for measuring space radiation on board. Since then, the Lunar Lander Neutron and Dosimetry (LND) instrument has been measuring temporally resolved cosmic radiation for the first time. Earlier devices could only record the entire 'mission dose'. In its current issue, the scientific journal Science Advances reports on the work of the international group of scientists involved with the LND, including researchers from the German Aerospace Center (Deutsches Zentrum für Luft- und Raumfahrt; DLR). Their investigations have involved more precise radiation measurements on the Moon.

The launch of the CZ-4B rocket on 21 September included the use of re-used grid fins to guide and locate fallen parts of the first stage more accurately. Those grid fins were recovered from a CZ-4B launched in 2019. After ensuring that the structure was complete, scientists repaired its heat-resistant coating to make it reusable, sources with the China Aerospace Science and Technology Corporation said. According to the company, the grid fins used in the 21 September launch narrowed the range of the landing areas by more than 85 percent.
