India's ISRO to Launch NISAR Satellite on July 30, First Joint Earth Observation Mission with NASA

The NASA-ISRO Synthetic Aperture Radar (NISAR) satellite will be launched on July 30, 2025, aboard an Indian GSLV-S16 rocket. Weighing 2,392 kg, NISAR is a unique Earth observation satellite with a dual-frequency Synthetic Aperture Radar (NASA's L-band and ISRO's S-band) and will observe the Earth with a swath of 242 km and high spatial resolution. The satellite will aid in disaster management, monitor climate change, and benefit India, the US, and the world.

The NASA-ISRO Synthetic Aperture Radar (NISAR) satellite is set to launch on July 30, 2025, aboard an Indian GSLV-S16 rocket. This unique Earth observation satellite, developed jointly by NASA and the Indian Space Research Organisation (ISRO), weighs 2,392 kg and is equipped with a dual-frequency Synthetic Aperture Radar (NASA's L-band and ISRO's S-band) [2].

NISAR will observe the Earth with a swath of 242 km and high spatial resolution, utilizing SweepSAR technology for the first time. The satellite is designed to aid in disaster management, monitor climate change, and benefit India, the United States, and the entire world. It will be launched from the Satish Dhawan Space Centre, Sriharikota, at a distance of 740 km [2].

The launch of NISAR marks a significant milestone in the growing collaboration between NASA and ISRO. The satellite will provide high-resolution data to help decision-makers, communities, and scientists monitor major infrastructure, agricultural fields, and the movement of land and ice surfaces [1].

The NISAR mission is part of a broader effort to enhance U.S.-India civil space cooperation. It is expected to contribute to areas such as agriculture and the preparation and response to disasters like hurricanes, floods, and volcanic eruptions [1].

NASA will provide live coverage of the launch activities on its website and social media platforms, allowing the public to engage with the mission in real-time. The launch broadcast begins from NASA’s Jet Propulsion Laboratory in Southern California [1].

In addition to NISAR, ISRO has announced that a humanoid called Vyommitra will be sent into space in December 2025 as part of India's human spaceflight mission, Gaganyaan [2].
