With greenhouse gas monitoring becoming a major concern, China has unveiled an ambitious plan for environmental satellite development, vowing to establish a rapid response system as part of a space-ground integrated network by 2035. It comes in response to the urgent need for a remote sensing monitoring system to support the national climate targets of peak carbon dioxide emissions before 2030 and carbon neutrality before 2060, according to the 2021-35 Plan published by the Ministry of Ecology and Environment earlier this month.

With the ambition to tackle the space-junk problem, Chinese aerospace scientists have managed to use a large "sail" to de-orbit spacecraft at the end of their life. The de-orbiter is a sail-like device made of a thin film, the thickness of which is less than one tenth of the diameter of a hair. Folded, it is approximately the size of an adult's palm, but it can cover an area of 25 square meters when unfolded. When a spacecraft is decommissioned, the sail onboard can be automatically opened. Once deployed, it will increase the effects of air friction, slowing the spacecraft in orbit and speeding up its descent into the Earth's atmosphere, where it will burn up. The latest test was done during the launch of the CZ-2D on 23 June.

CNSA on 21 November launched a national platform for remote sensing data and application services in Haikou, on Hainan Island. Also on that day, CNSA held an opening ceremony for both its international satellite data and application cooperation center and the BRICS center for remote sensing satellite constellation data and application (China) in Haikou. CNSA said that the establishment of the platform and the two centers are of great significance.
