TRISHNA Indo‑France Satellite to be Launched in Next 12‑16 Months
Syllabus: Space technology and international cooperation in science and technology
The news
The Indo‑French satellite TRISHNA (Thermal Infra‑Red Imaging Satellite for High‑resolution Natural Resource Assessment) is in the advanced realisation stage and is slated for launch in the next 12‑16 months. It is the third joint satellite project between India and France after Megha‑Tropiques and SARAL. ISRO's URSC will build the satellite bus while CNES will supply half of the payloads; data will be processed jointly in both countries. The mission will carry a Thermal Infra‑Red payload from CNES and a Visible‑Near Infra‑Red Short Wave Infra‑Red payload from ISRO, aimed at high‑resolution monitoring of surface temperature, emissivity and water resources. An open data policy will make the scientific data freely available worldwide.
Background in one line: Conceptualisation (≈10 yrs) → Formalisation → Realisation stage → Bus built by URSC + payloads from CNES & ISRO → Joint data processing → Launch (12‑16 months)
Static syllabus linkage
- ISRO – Indian Space Research Organisation (established 1969)
