Indian Space Research Organisation (ISRO) has started the final preparation for one of its most highly anticipated global collaborations after a prolonged wait. The joint mission with the United States’ National Aeronautics and Space Administration (NASA) as the NASA-ISRO Synthetic Aperture Radar, or NISAR, is scheduled to take off in June 2025. The ambitious Earth observation satellite will have one of the largest and most advanced radar imaging systems ever to have been launched into space. When in operation, NISAR will offer a new window of the Earth’s surface, with critical information about Earth’s changing systems, natural hazards, and environmental change.

Technical Challenges and Assembly Progress According to the news from NASA’s own NISER blog, the launch was initially planned for 2024. It was continuously postponed because of technical problems, such as concerns over the satellite’s 12-meter radar antenna reflector overheating. To enhance its reflective coating and manage temperature issues …
