How US-Indian NISAR Satellite Will Offer Unique Window on Earth
NASA | January 6, 2025
The NASA-Indian Space Research Organization (ISRO) NISAR (NASA-ISRO Synthetic Aperture Radar) satellite is scheduled to launch in early 2024. It will carry an advanced radar instrument that will measure changes in the Earth’s surface with unprecedented detail.
NISAR will provide a unique window on Earth’s processes, from the movement of tectonic plates to the growth of forests. It will also help us to better understand the impacts of climate change, such as sea level rise and changes in ice cover.
How NISAR Works
NISAR’s radar instrument will emit pulses of radar energy toward Earth’s surface. The radar energy will bounce off the surface and return to the satellite, where it will be processed to create images.
The radar instrument will operate at two different frequencies: L-band (24 centimeters) and S-band (12 centimeters). The L-band radar will be able to penetrate through vegetation and soil, while the S-band radar will be able to provide high-resolution images of the Earth’s surface.
NISAR’s Science Objectives
NISAR’s science objectives are to:
- Measure changes in the Earth’s surface with unprecedented detail.
- Improve our understanding of the Earth’s processes, from the movement of tectonic plates to the growth of forests.
- Help us to better understand the impacts of climate change, such as sea level rise and changes in ice cover.
NISAR’s Benefits
NISAR will provide a wealth of benefits to scientists and policymakers around the world. It will help us to:
- Improve our understanding of the Earth’s system.
- Address challenges such as climate change and natural disasters.
- Develop new technologies and applications that benefit society.
NISAR is a major international collaboration between NASA and ISRO. It is a testament to the power of science to bring nations together to address global challenges.
Additional Information
- The NISAR satellite will be launched into a sun-synchronous orbit, which means that it will pass over the same point on Earth at the same time each day.
- The NISAR satellite will have a mass of approximately 2,800 kilograms (6,200 pounds).
- The NISAR satellite will be operated by NASA and ISRO.
- The NISAR data will be available to scientists around the world.
