The upcoming NISAR satellite, jointly developed by NASA and ISRO, is exposing stark contrasts in their operational models. Set to launch on July 30, 2025, from Sriharikota aboard an ISRO GSLV rocket, the mission will use dual-frequency radar (L-band by NASA and S-band by ISRO) to monitor Earth’s surface changes globally every 12 days.While NASA invested over $1.15 billion, ISRO delivered its share at just $100 million, highlighting its cost-effective, in-house approach. The mission underscores both India’s rising global space profile and the growing reliance on frugal innovation for cutting-edge science. (PC: NDTV)
