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?

  1. 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
  2. B
    The satellite is designed to operate in a Geostationary Orbit (GEO) at an altitude of 35,786 km for continuous deep-space solar wind observations.
  3. Its primary payload capability includes high-resolution thermal infrared imaging to evaluate land surface temperature, evapotranspiration, and crop water stress.Cevap
  4. D
    The 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.

Adım Adım Çözüm

1
Analyze the organizational collaboration of the TRISHNA space mission.
TRISHNA is a bilateral joint initiative between India (ISRO) and France (CNES) focused on Earth observation.
Identifying the partnering agencies confirms the organizational framework of the mission.
2
Evaluate the orbital profile and primary operational domain of the satellite.
The satellite operates in a Sun-Synchronous Orbit (SSO) in Low Earth Orbit (LEO) for periodic land surface imaging, rather than Geostationary Orbit (GEO).
Thermal mapping of land surface dynamics requires consistent illumination geometry provided by Sun-Synchronous LEO.
3
Assess the scientific objectives and payload focus of TRISHNA.
The mission provides high-spatial and high-temporal resolution thermal infrared data for quantifying land surface temperature, evapotranspiration, and agricultural water usage.
Understanding the key scientific applications verifies the target parameters evaluated by the mission sensors.
