India Achieves Milestone With Successful Launch Of Nisar Satellite In Collaboration With NASA

Indian Space Research Organisation (ISRO) successfully launched the NISAR satellite, a collaborative effort with NASA, from Sriharikota's Satish Dhawan Space Centre. The NASA-ISRO Synthetic Aperture Radar (NISAR) was carried into space by the GSLV-F16 rocket at 5:40 pm. This mission marks a significant milestone in earth observation technology.

Union Minister of Science and Technology, Jitendra Singh, praised India's role in this collaboration with NASA. "Through this biggest collaboration with NASA-an agency established long before its Indian counterpart-we are contributing as equal partners in the game-changing experiments," he stated. Singh highlighted that this achievement follows closely after the Axiom-4 mission.

Technological Advancements and Benefits

The NISAR satellite, weighing 2,392 kg, took nearly ten years and over USD 1.5 billion to develop. It is designed to scan the entire planet every 12 days using two radar frequencies-L-band and S-band. These systems will monitor both large-scale and minute changes on Earth's surface, enhancing our understanding of climate dynamics.

The L-band radar, developed by NASA, can detect subtle land shifts and penetrate dense vegetation. Meanwhile, ISRO's S-band radar captures broader surface features and can see through cloud cover. This dual-radar system will provide high-resolution images under all weather conditions, day or night.

Applications Across Various Sectors

NISAR's data will be invaluable for sectors like aviation, shipping, and agriculture by offering navigation data even in challenging conditions such as fog or dense clouds. The satellite's ability to penetrate ice layers will also benefit research in regions like Antarctica.

NASA has indicated that NISAR will offer crucial insights into changes in ice sheets, glaciers, and sea ice. It will also enhance scientific understanding of how deforestation, permafrost loss, and fires impact the carbon cycle. This data will be accessible through ISRO's website as an open-access resource.

Global Impact and Future Prospects

This mission is expected to extend benefits beyond disaster response for floods, cyclones, and landslides. By capturing detailed images of natural hazards like earthquakes and volcanic eruptions, scientists can better understand these phenomena's underlying processes.

The launch was witnessed by a team of NASA scientists who travelled to India's southeastern coast for the event. The GSLV-F16 rocket successfully placed NISAR into a sun-synchronous orbit at an altitude of 747 km approximately 20 minutes post-liftoff.
