With reference to the TRISHNA (Thermal InfraRed Imaging Satellite for High-resolution Natural Resource Assessment) mission featured in space technology developments, which of the following statements are correct?
- It is a joint collaborative Earth observation mission developed by the Indian Space Research Organisation (ISRO) and the French National Centre for Space Studies (CNES).Cevap
- BThe satellite is designed to operate in a Geostationary Orbit (GEO) at an altitude of 35,786 km for continuous deep-space solar wind observations.
- Its primary payload capability includes high-resolution thermal infrared imaging to evaluate land surface temperature, evapotranspiration, and crop water stress.Cevap
- DThe mission is an initiative under the European Space Agency (ESA) framework where ISRO acts solely as a launch service provider without payload development roles.
Cevap
The TRISHNA mission is a joint Earth-observation initiative co-developed by ISRO (India) and CNES (France), placed in Sun-Synchronous Low Earth Orbit to monitor land surface temperature, evapotranspiration, and water resources using high-resolution thermal infrared sensors.
The statements highlighting that TRISHNA is a joint ISRO-CNES Earth observation mission and that its primary payload capability measures land surface temperature, evapotranspiration, and water stress are accurate. Both ISRO and CNES jointly developed the instrument suite (TIR and VNIR/SWIR) to deliver actionable data on global hydrologic cycles and eco-climatic monitoring.
