How the exam will ask it
ப்ரிலிம்ஸ்
- TRISHNA is a joint ISRO-CNES (France) satellite mission, following Megha-Tropiques and SARAL.
- Megha-Tropiques studies the tropical water cycle and energy exchanges, while SARAL carries an altimeter for ocean surface studies.
- TRISHNA is a bilateral India-France project, not a NASA or ESA mission; NASA's joint mission with ISRO is NISAR.
மெயின்ஸ்
GS-III (Science and Technology) and GS-II (International Relations): India-France space cooperation has moved from Megha-Tropiques and SARAL to TRISHNA, showing a durable bilateral partnership in earth observation. Such missions support climate, water and land-resource monitoring and deepen strategic ties with France. The way forward is to pair joint missions with indigenous capability building, open data use and timely launches.
