China launched a new Earth-observation satellite from the Jiuquan Satellite Launch Center in northwestern China on April 7. The satellite, Gaofen-3 03, was launched by a Long March-4C carrier rocket at 7:47 a.m. (Beijing Time) and it entered the planned orbit successfully. It will mainly be used to obtain reliable and stable high-resolution synthetic aperture radar images and to provide operational application data support for China's marine development, terrestrial environmental resource monitoring and emergency disaster prevention and mitigation. The launch marks the 414th mission for the Long March series carrier rockets.
