Question
A new Earth Observation Satellite “Gaofen-3
03” was recently launched by_______?Solution
China successfully launched a new Earth observation satellite which will become part of its land-sea radar satellite constellation and capture fine-resolution images to help Beijing safeguard its maritime rights and interests. The satellite Gaofen-3 03 was launched from Jiuquan Satellite Launch Center by a Long March-4C rocket and has entered the planned orbit successfully. The satellite will be networked with the orbiting Gaofen-3 and Gaofen-3 02 satellites to form a land-sea radar satellite constellation and capture reliable, stable synthetic aperture radar (SAR) images. It will serve the fields of marine disaster prevention and mitigation, dynamic marine environment monitoring, marine research, environmental protection, water conservancy, agriculture and meteorology, while helping to safeguard maritime rights and interests. The Landsat-9 satellite was launched last September and started operation in January this year.
