China successfully launches new ocean observation satellite ‘Haiyang-2D’

• China successfully launched a new ocean-monitoring satellite Haiyang-2D (HY-2D) into orbit on May 19, 2021, on Long March-4B rocket, from the Jiuquan Satellite Launch Centre in northwest China.
• The HY-2D will form a constellation with the HY-2B and HY-2C satellites to build an all-weather and round-the-clock dynamic ocean environment monitoring system of high frequency and medium and large scale to provide early warning on marine disasters.
• The constellation will support China in detecting early warning and prediction of marine disasters, sustainable development and utilisation of ocean resources, effective response to global climate change as well as ocean research.
