NASA-ISRO $1.5 billion joint satellite NISAR set for launch on July 30: What is its mission and why is ISRO spending so much on it |
The countdown has begun for the launch of NISAR, a groundbreaking Earth statement satellite collectively developed by NASA and ISRO. Slated for liftoff on July 30, 2025, at 5:40 PM IST from Sriharikota, the satellite represents a landmark in Indo-US house collaboration. Weighing 2,392 kg and carrying a price ticket of $1.5 billion, NISAR is the most costly Earth statement mission ever launched. Using a first-of-its-kind dual-frequency radar system, the satellite goals to ship detailed, high-resolution imagery of the Earth’s floor each 12 days. It is designed to assist scientists, catastrophe response groups, and policymakers worldwide.
What is the mission of the NISAR
NISAR, which stands for NASA-ISRO Synthetic Aperture Radar, will orbit Earth in a sun-synchronous orbit, capturing world floor information constantly below equivalent lighting situations. Its major targets embody:
- Monitoring ecosystem adjustments and measuring forest biomass
- Tracking earthquakes, landslides, and volcanic deformation
- Studying glacier retreat and polar ice motion
- Measuring soil moisture and detecting groundwater variations
- Generating 3D floor maps of land and ice with excessive precision
The satellite’s L-band radar from NASA and S-band radar from ISRO enable it to see via cloud cowl, vegetation, and darkness, enabling round the clock, all-weather observations.
Why does NISAR value $1.5 billion?
NISAR’s hefty value stems from its technological sophistication.
- It carries a 12-meter deployable mesh antenna, one of many largest in Earth statement historical past.
- The satellite integrates two superior radar programs, requiring advanced {hardware} and software program integration with out mutual interference.
- It affords centimeter-level precision, able to detecting delicate floor shifts and environmental adjustments.
NASA offered the L-band radar, GPS, solid-state recorder, and antenna. ISRO developed the S-band radar, satellite bus, and launch programs, and will launch NISAR utilizing the GSLV-F16 rocket.
Why is ISRO investing over INR 788 crore?
India’s contribution of INR 788 crore is a strategic funding with far-reaching advantages.
- Disaster response: Rapid detection of earthquakes, floods, and landslides may assist save lives and infrastructure.
- Agriculture and water administration: Accurate information on soil moisture and crop well being can inform drought mitigation and enhance meals safety.
- Climate monitoring: Continuous monitoring of forests, glaciers, and wetlands enhances local weather resilience.
- Technological development: Developing and working dual-band radar expertise strengthens ISRO’s future missions.
- Global information entry: All NISAR information might be freely accessible worldwide, enhancing India’s standing in world Earth science.
The larger image: An emblem of worldwide collaboration
NISAR exemplifies the success of long-term technical cooperation between NASA and ISRO.
- It showcases a trusted partnership in cutting-edge house expertise.
- It positions India as a worldwide chief in Earth statement.
- It opens doorways for future joint missions and high-tech house ventures.
NISAR is greater than only a satellite. It is a logo of scientific ambition, world cooperation, and a step ahead in understanding our quickly altering planet. With unmatched capabilities and broad sensible purposes, it is anticipated to ship insights that far exceed its monetary value. As India takes the lead in launching the mission, the world watches carefully, anticipating a transformative leap in Earth science and local weather preparedness.
