On Thursday, China bolstered its ocean observation and environmental monitoring capabilities with the successful launch of the Haiyang-2E (HY-2E) marine satellite. This latest addition to China’s satellite constellation was launched aboard a Long March 4B rocket from the Jiuquan Satellite Launch Center in northwest China at 7:46 a.m. Beijing time. This mission marks the 654th flight of the Long March rocket series, underlining China’s growing expertise in space technology.
The HY-2E satellite, crafted by the China Academy of Space Technology (CAST), joins the Haiyang-2 series, China’s pioneering satellite network dedicated to marine dynamic environment monitoring. HY-2E is set to replace the HY-2B satellite, which was launched in 2018, and will work in tandem with the existing HY-2C and HY-2D satellites. Together, this constellation provides a continuous stream of data crucial for marine observation and forecasting, playing a vital role in enhancing environmental monitoring services.
Equipped with four state-of-the-art microwave remote sensing instruments, the HY-2E satellite is designed to collect comprehensive data on sea surface conditions. Its payloads will measure sea surface height, wave height, wind fields, and sea surface temperature. This data is invaluable for improving marine weather forecasts, conducting climate research, and studying phenomena like El Niño, thereby increasing the accuracy and reliability of oceanic observations.
Since its inception, the Haiyang-2 satellite program has been instrumental in areas such as disaster prevention, maritime safety, and scientific research. The satellites have provided critical data for tracking typhoons, supporting tsunami early warning systems, and enhancing global numerical weather prediction models. They have also contributed significantly to marine resource management and efforts to bolster national maritime security.
Beyond its primary weather and climate applications, the Haiyang-2 satellite series offers tangible benefits to the fishing and shipping industries. By providing data on ocean currents, wind, and wave conditions, the satellites help identify productive fishing grounds, enabling vessels to operate more efficiently and cost-effectively. Additionally, since the launch of HY-2B, the satellites have been outfitted with an Automatic Identification System (AIS), which allows for continuous tracking of vessel positions, speeds, and identification details, thus improving navigation safety along busy sea routes.
