China successfully sent a new ocean-monitoring satellite into orbit as part of its effort to build an all-weather and round-the-clock dynamic ocean environment monitoring system which would provide early warning on marine disasters. The satellite was launched by a Long March-4B rocket carrying the Haiyang-2D (HY-2D) satellite from the Jiuquan Satellite Launch Centre in northwest China.

What

  1. 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.
  2. The constellation will support the country's 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.
  3. The HY-2D was developed by the China Academy of Space Technology, and the carrier rocket by the Shanghai Academy of Spaceflight Technology. This launch was the 370th by the Long March rocket series.
  4. China's space programme made significant advancements last week when it landed a spacecraft on Mars, becoming the second country after the United States to have a rover on the red planet.

Flashback

  1. Currently, ISRO has three dedicated satellites in the orbit viz. Oceansat-2, SARAL and SCATSAT-1 for oceanographic observations.
  2. The data from these satellites is used to generate information on Photo-synthetically Active Radiation, ocean primary production, aerosol optical depth, total suspended sediments, suspended sediment concentration, ocean surface winds, ocean altimetry and ocean state forecast.
