Key Details of Agreement:
Background: The ISRO–ESA partnership, which began in 1978 and was renewed in 2002, has expanded to areas such as Earth observation, navigation systems, ground station support, human spaceflight, Chandrayaan and Aditya missions, and deep-space communications.
Impact: The collaboration will contribute significantly to global climate monitoring, environmental research, and disaster management by providing more actionable and precise data.
Key Mission: The agreement specifically supports the upcoming Fluorescence Explorer (FLEX) mission, an ESA Earth Explorer satellite designed to monitor global vegetation health by measuring chlorophyll fluorescence.
