China sent five satellites into orbit aboard a Long March-11 carrier rocket at 11:30 a.m. on Saturday from a platform in the East China Sea. The new Earth-observation satellites have since successfully entered their predetermined orbit and will provide commercial service for natural resource surveys, urban planning, disaster monitoring and other tasks, according to reports. They are part of the Jilin-1 Gaofen satellite series – gaofen is an abbreviation for "high resolution" in Chinese. The series is expected to have 138 satellites by 2025 and become the largest commercial observation constellation in China.
