Context: The Indian Space Research Organisation (ISRO) recently launched INSAT-3DS, a new-generation meteorological satellite designed for enhanced monitoring of the Earth’s surface, atmosphere, oceans, and environment.

INSAT-3DS

  • About: INSAT-3DS Satellite represents a follow-on mission of the Third Generation Meteorological Satellite from Geostationary Orbit.
  • Orbit Adjustment: Subsequent orbit-raising maneuvers will ensure that the satellite is positioned in a Geo-stationary Orbit, optimizing its functionality.
  • Funding and Support: GSLV-F14/INSAT-3DS mission is fully funded by the Ministry of Earth Sciences (MoES), highlighting government support for advanced meteorological endeavors.
  • Enhanced Capabilities: The mission is designed for enhanced meteorological observations and monitoring of land and ocean surfaces for weather forecasting and disaster warning.
  • Augmentation of Services: The INSAT-3DS satellite will augment the Meteorological services alongside the presently operational INSAT-3D and INSAT-3DR satellites, bolstering India's capabilities in weather monitoring.

Why GSLV?

  • Enhanced capacity: GSLV stands out as a more potent rocket in comparison to PSLV due to its enhanced capacity and strength.
  • Payload Capacity to Geostationary Orbits: GSLV demonstrates its prowess by transporting payloads exceeding 2,200 kg to geostationary orbits.
  • Payload Capacity to Low Earth Orbits: The rocket can carry payloads exceeding 6,000 kg to low earth orbits, showcasing its robust performance.
  • Understanding Cryogenics: Cryogenics, the field of science dealing with the behavior of materials at extremely low temperatures, plays a crucial role in GSLV's operation and its engine's performance.
