Abstract: A LM-4C carrier rocket lifted off from the Jiuquan Satellite Launch Center at 06:45 Beijing time on March 31, 2021, successfully sending the Gaofen 12-02 satellite into its preset orbit. This was the 73rd mission of LM-4B series launch vehicle, also the 364th flight of LM series launch vehicle. 
The satellite, developed by the Shanghai Academy of Spaceflight Technology (SAST) under CASC, was designed to be use in areas such as land survey, city planning, confirmation of land right, route and network design, crops yield estimation and disaster prevention and mitigation. 
The LM-4C is a conventional liquid three-stage carrier rocket developed by SAST. It is capable of launching various types of satellites with different orbit requirements and carrying out single satellite or multiple-satellite launch missions with one rocket. Its launch capacity into a 700 km sun-synchronous orbit is up to 3 tons.
