China's hyperspectral satellite for Earth observation has gone into use after completing in-orbit tests, the Ministry of Ecology and Environment, the primary developer of the spacecraft, announced on Tuesday. The satellite, Gaofen-5 02, was launched into space on Sept. 7, 2021. Designers mounted seven payloads on it, including short-wave infrared hyperspectral cameras. The onboard devices will monitor air, water, and land, strengthening China's environmental protection efforts to fight pollution and provide support for achieving the carbon peaking and neutrality goals, said the ministry.
