Understanding NISAR Satellite
The NISAR (NASA-ISRO Synthetic Aperture Radar) satellite is a collaborative effort between NASA and the Indian Space Research Organisation (ISRO) aimed at Earth observation. Here’s a detailed explanation of the statements provided:
Statement-I: Precision in Monitoring Tectonic Movements
- NISAR is designed to monitor Earth's tectonic movements with remarkable precision.
- It can achieve accuracy down to the centimeter, which allows for detailed analysis of land deformation and seismic activity.
Statement-II: Use of Synthetic Aperture Radar (SAR)
- NISAR employs Synthetic Aperture Radar (SAR) technology.
- SAR is effective in generating high-resolution images of the Earth's surface, utilizing radar waves instead of optical sensors.
- This technology enables the satellite to collect data regardless of weather conditions or light levels, making it a powerful tool for Earth observation.
Conclusion: Correctness of Statements
- Both statements are correct.
- Statement-II provides the technological foundation that enables the capabilities outlined in Statement-I.
- Thus, Statement-II explains how NISAR achieves its precision in monitoring tectonic movements.
In summary, the correct option is (a): Both Statement-I and Statement-II are correct, and Statement-II explains Statement-I. The integration of SAR technology is critical to the effectiveness of the NISAR satellite in monitoring Earth's geological changes.
