ISRO-NASA’s Game-Changing Collaboration, NISAR to Track Earth Surface Motions with Unprecedented Accuracy!

The Indian Space Research Organisation (ISRO) and the National Aeronautics and Space Administration (NASA) are collaborating on a groundbreaking mission to launch the NASA-ISRO Synthetic Aperture Radar (NISAR) satellite. This cutting-edge satellite will enable humans to track Earth’s surface motions with unprecedented accuracy, down to fractions of an inch. In this blog, we will delve into the features, applications, and benefits of the NISAR satellite.

What is NISAR?

NISAR is a dual-frequency radar satellite that will measure the motion of the Earth’s surface, providing valuable insights into climate change, earthquake-prone areas, and volcanic activity. The satellite is equipped with L-band and S-band radar systems, built by NASA and ISRO, respectively.

These instruments enable the collection of measurements during both day and night and can even see through clouds using the L-band. Before proceeding further, take a look at: ITBP Recruitment 2024: Apply Now for 526 SI, Constable, and Head Constable Vacancies! Read All the Details Here!

Key Features of NISAR

Some of the key features of NISAR include:

• High-Resolution Imaging: NISAR will provide high-resolution images of Earth’s surface, enabling researchers to track changes in land cover, land use, and vegetation.
• Dual-Frequency Radar: The satellite’s dual-frequency radar system allows it to penetrate dense vegetation and clouds, providing accurate measurements.
• Global Coverage: NISAR will measure the motion of the entire planet’s land and ice-covered surface every 12 days.
• Accuracy: NISAR’s accuracy will be unprecedented, tracking surface motions down to fractions of an inch.

Earthquake Prediction and Monitoring

One of the primary applications of NISAR is earthquake prediction and monitoring. While It won’t predict earthquakes, it will:

• Identify Susceptible Areas: NISAR will identify areas prone to seismic activity, enabling researchers to focus on high-risk zones.
• Detect New Earthquake-Prone Areas: The satellite will detect new earthquake-prone areas in unmonitored regions.
• Monitor Himalayan Plate Boundary: ISRO’s Solid Earth Science Lead, Sreejith K M, emphasizes the importance of monitoring the Himalayan plate boundary, which has produced significant earthquakes in the past.

Volcanic Activity and Land Movement

NISAR will also detect land movements prior to volcanic eruptions, providing valuable insights into:

• Deformation Patterns: NISAR will track deformation patterns, helping scientists understand why volcanoes deform.
• Signs of Eruption: The satellite will identify potential signs of eruption, enabling early warnings.
• Volcanic Activity Monitoring: NISAR will monitor volcanic activity globally, providing critical data for researchers.

Additional Applications

NISAR’s applications extend beyond earthquake and volcanic monitoring:

• Climate Change Research: NISAR will track changes in glaciers, ice sheets, and sea ice.
• Vegetation Mapping: The satellite will map vegetation changes and understand climate impacts.
• Infrastructure Monitoring: NISAR will monitor structures like levees, aqueducts, and dams.
