NASA-ISRO to launch advanced NISAR satellite on July 30 for global climate and Earth monitoring: Key timings, how to watch live and other important information |

The Indian Space Research Organisation (ISRO), in collaboration with the National Aeronautics and Space Administration (NASA), is making ready for considered one of its most vital house ventures to date—the launch of the NASA-ISRO Synthetic Aperture Radar (NISAR) satellite. Scheduled for liftoff on July 30, 2025, at 5:40 PM IST, the mission will use the GSLV-F16 rocket from the Satish Dhawan Space Centre, Sriharikota. NISAR represents a landmark in worldwide house collaboration, integrating NASA’s experience in L-band radar expertise with ISRO’s advanced S-band radar techniques. The mission is designed to produce high-resolution, all-weather, day-and-night imaging of Earth, enabling scientists to monitor crucial environmental adjustments reminiscent of land subsidence, glacier motion, and ecosystem well being with unmatched precision. This makes NISAR some of the advanced Earth remark missions ever developed.

NASA-ISRO’s NISAR launch: Schedule timings and how to watch live

The NISAR launch occasion will probably be streamed live on ISRO’s official YouTube channel, beginning at 5:10 PM IST to enable global audiences to witness the historic second. Following liftoff, the GSLV-F16 rocket will place the NISAR satellite right into a Sun-synchronous polar orbit at an altitude of 740 kilometers inside 19 minutes of flight. This orbit will allow steady protection of Earth’s floor below constant lighting circumstances, which is essential for correct knowledge comparability over time.This launch is notable as it’s ISRO’s 102nd general mission and its first GSLV launch devoted to a radar-based Earth remark satellite. The mission underscores India’s rising position in global house science and its means to execute extremely advanced worldwide collaborations.

What will NISAR research

The NASA-ISRO Synthetic Aperture Radar (NISAR) mission is designed to research Earth’s altering dynamics in unprecedented element, offering important knowledge for the global scientific group. According to ISRO, the satellite’s major targets embody:

NISAR can even focus on seasonal adjustments in forest cowl, detect mountain shifts, and monitor glacier actions in crucial areas such because the Himalayas, Antarctica, and polar areas. This knowledge will enhance climate modeling, catastrophe preparedness, and pure useful resource administration.

How lengthy did it take to develop NISAR

The NISAR mission has been a decade within the making, taking 8–10 years to design, develop, and combine its advanced payloads and techniques. Scientists from ISRO and NASA labored in shut collaboration, combining their radar applied sciences and engineering experience to construct some of the refined Earth remark satellites ever developed.Following its launch, scientists will conduct an preliminary part generally known as satellite commissioning, making certain all techniques operate optimally earlier than full-scale Earth remark operations start.

Why NISAR is a game-changer for Earth remark

NISAR is considered essentially the most advanced radar imaging satellite ever developed by NASA and ISRO. It carries two refined radar techniques:

This dual-band functionality offers NISAR an unparalleled benefit in offering all-weather, day-and-night knowledge, unaffected by cloud cowl or atmospheric circumstances. The knowledge will allow steady monitoring of Earth’s ecosystems, serving to predict pure disasters like earthquakes, floods, and landslides. Scientists can even use it to research crop well being, city growth, and the affect of climate change on polar ice caps and sea ranges.(*30*)

GSLV F16: Three-stage rocket with cryogenic higher stage

The Geosynchronous Satellite Launch Vehicle (GSLV) F16 is a three-stage rocket engineered for heavy-payload missions. Standing 51.7 meters tall and weighing roughly 420 tons, it includes:

This marks the ninth use of an indigenous cryogenic stage, showcasing India’s self-reliance in high-end house propulsion expertise. The cryogenic engine’s effectivity is crucial in reaching exact orbital insertion, permitting NISAR to operate at its full potential for Earth remark missions.

Global Impact of NISAR knowledge

NISAR is designed to scan the whole planet twice each 12 days. Over its three-year baseline mission, it’ll present high-resolution imagery of Earth each six days, enabling near-real-time environmental monitoring. Unlike earlier Indian Earth remark satellites that primarily centered on home purposes, NISAR’s global mission profile means its knowledge will profit scientists, governments, and industries worldwide.Applications of NISAR knowledge embody:

By delivering steady, high-quality radar knowledge, NISAR is predicted to remodel global environmental administration and climate analysis, making it some of the influential Earth science missions of this decade.Also Read | NASA alert!
