GAOFEN- 502 EARTH-OBSERVING SATELLITE BY CHINA

Context:

On September 07, 2021, China successfully launched a new Earth observation satellite, Gaofen-502, into space.

About the Launch:

  • The China Aerospace Science and Technology Corporation (CASC)announced the success of the launch of the satellite once it entered its planned orbit.
  • It was launched using a Long March-4C rocket, from the Taiyuan Satellite Launch Centre in north China’s Shanxi Province.
  • According to the U.S. space tracking the satellite is in a roughly 426 mile (685 kilometres) altitude orbit inclined by 98 degrees.

Gaofen-5 02:

  • It is a hyperspectral satellite that will be used for comprehensive environmental monitoring, to improve the country’s hyperspectral observation capacity of the atmosphere, water and land.
  • Hyperspectral imaging means the satellite will monitor hundreds of very narrow channels of light, from ultraviolet to long-wave infrared, allowing the satellite to produce images indicating the chemical-physical composition of objects in the image.
  • It is the 2nd of two identical Gaofen 5 satellites developed by the Shanghai Academy of Spaceflight Technology (SAST), one of the major arms of CASC.
  • The satellite is based on a SAST3000 platform and carries seven instruments for hyperspectral monitoring of the atmosphere, water and land.
