NASA-ISRO NISAR Satellite: Uniting Space Agencies



  Jan 24, 2024

NASA-ISRO NISAR Satellite



1. What is the NISAR satellite?

NISAR (NASA-ISRO Synthetic Aperture Radar) is a collaborative satellite mission between NASA and ISRO. It is designed to monitor Earth's landscapes and study the impacts of climate change.

2. What are the key features of NISAR?

NISAR will scan Earth's surface using two different synthetic aperture radar (SAR) systems. NASA is developing the L-band SAR, while ISRO is developing the S-band SAR. These systems will provide detailed observations of Earth using different wavelengths.

3. What is the primary goal of the NISAR mission?

The main goal of NISAR is to track changes in Earth's landscapes over time. It will focus on forests and wetlands, which are crucial carbon sinks, to understand their role in carbon sequestration and the impacts of human activities.

4. How often will NISAR scan the Earth?

NISAR is designed to scan all of Earth's land and ice surfaces every 12 days. This frequent monitoring will provide up-to-date data on changes in the Earth's surface.

5. Why are forests and wetlands important for the NISAR mission?

Forests and wetlands are vital for the study because they act as significant carbon sinks. Understanding how these ecosystems are changing due to human activities like farming and urban expansion is crucial for assessing their capacity to store carbon dioxide.

6. What are the benefits of the NISAR mission for climate science?

NISAR will enhance our understanding of carbon sources and sinks from terrestrial ecosystems, especially forests. This data is critical for developing strategies to mitigate climate change impacts.

7. When and where is NISAR scheduled to launch?

NISAR is set to launch in early 2024 from ISRO's Satish Dhawan Space Center in southern India.

8. What makes the NISAR mission unique?

This mission marks the first time the U.S. and India have cooperated in developing hardware for an Earth-observing mission, representing a significant step in international space collaboration.
