Indian rockets have taken the tropical weather satellite Megha-Tropiques, jointly produced by South Asia and France, together with 3 smaller satellites, orbiting from the aerospace airport in Sriharikota, Hindustan Times believe. The total weight of 4 satellites is about 1,042.6 kg.

After about 22 minutes of being launched from the ground, Megha-Tropiques satellite began to separate from PSLV-C18 rocket. Other satellites, SRMSAT , VesselSat and Jugnu, do the same thing in turn. The whole process of satellites is launched from the ground and separated from the rocket that lasts about 25 minutes.

Megha-Tropiques satellite will have the ability to study climate and help scientists have new weather forecast models with circular orbit 20 degrees above the equator of the earth. SRMSAT satellites are responsible for monitoring greenhouse gases, carbon dioxide and water vapor in the air. VesselSat satellites are used to monitor vessels on the sea automatically, through the signals that these vessels send. And Jugnu satellite is expected to be used to test a camera system developed by India to capture the earth.

The weather research satellite program is the result of cooperation between India and France, with the aim of gathering more information to assess how global warming affects the rainy season on earth.
