• A. To support low-earth orbit operations at reduced altitude
• B. To enable cost-efficient satellite passes through optimized fuel consumption
• C. To ensure consistent caching of data before transmission to ground stations
• D. To achieve temporal resolution for global coverage and land deformation monitoring

Answer 1

Answer:

D. To achieve temporal resolution for global coverage and land deformation monitoring

Mission Purpose: The NISAR mission is a joint collaboration between NASA and ISRO, utilizing a sophisticated dual-frequency Synthetic Aperture Radar (SAR) system.
