TIL Desk/World/Beijing/ China sent a resource satellite and two smaller ones into planned orbits on Thursday. They were launched on a Long March-4B carrier rocket at 11.26 a.m. from the Taiyuan Satellite Launch Centre in Shanxi province.
The resource satellite, ZY-1 02D developed by the China Academy of Space Technology (CAST), will provide observation data for natural resources asset management, ecological monitoring, disaster prevention and control, environmental protection, urban construction, transportation and contingency management.
With an expected lifespan of five years, ZY-1 02D carries a near-infrared camera with a coverage width of 115 km, enabling it to observe large and medium-sized cities, and be used for urban planning, said the satellite’s project manager. The satellite can also be used to observe chlorophyll concentration, water transparency and total suspended matter concentration in lakes to help monitor the environment and prevent water pollution.
