Why NISAR is Important?
🌍 Comprehensive Earth Monitoring
NISAR will scan the entire Earth's land and ice surfaces every 12 days, making it the most frequent global radar imaging mission. It will track even the smallest changes in Earth's surface, including landslides, glacier movements, and vegetation changes.
🔥 Natural Disaster Response
The satellite will be a game-changer for disaster management. It will provide crucial data on earthquakes, volcanic activity, floods, landslides, and tsunamis. Early detection of these events can help minimize destruction and save lives.
🌱 Agriculture and Ecosystem Studies
NISAR will help in monitoring forest cover, soil moisture levels, and agricultural productivity. It will also assist in mapping deforestation and climate-related changes.
❄️ Climate Change Analysis
By tracking polar ice sheets, sea-level rise, and melting glaciers, NISAR will help scientists understand the effects of global warming and climate change.
