Non-communicable diseases have become increasingly prevalent in India due to several factors:
Front-of-pack labeling could significantly influence consumer behavior and public health outcomes:
Conclusion: The Access to Nutrition Initiative report emphasizes the urgent need for healthier food portfolios in LMICs (Low- and Middle-Income Countries), equitable pricing, and front-of-pack labeling to combat non-communicable diseases. These steps align with SDG 3 (Good Health and Well-being), promoting healthier lives globally.

| Collaboration | • Joint mission between NASA (United States) and ISRO (India). |
| Purpose | • Designed to monitor Earth’s natural processes and environmental changes, contributing to disaster preparedness, climate research, and sustainable management. |
| Launch Date | • Planned for early 2025. |
| Launch Location | • Satish Dhawan Space Centre, Andhra Pradesh, India. |
| Launch Vehicle | • ISRO’s Geosynchronous Satellite Launch Vehicle Mark II (GSLV Mk II). |
| Orbit | • Low Earth Orbit (LEO). |
| Dual-Band Radar System | • L-band radar (provided by NASA): Penetrates dense vegetation and tracks ground motion. • S-band radar (provided by ISRO): Enhances precision for surface monitoring. |
| Day and Night Functionality | • Operates 24/7, unaffected by weather conditions. |
| Large Antenna | • Diameter: 12 meters. • Structure: 39-foot reflector made from gold-plated wire mesh to focus radar signals effectively. |
| Features | • Scans Earth’s entire surface every 12 days.
• Measures surface changes with accuracy down to fractions of an inch. • Can penetrate vegetation and soil layers, providing 3D reconstructions of subsurface structures. |
| Areas of Study | • Ecosystems and Environmental Changes (forest biomass, deforestation, wetlands, agricultural lands, glaciers, and ice sheets). • Natural Disasters (seismic shifts, volcanic bulging, landslides, and tsunamis). |
| Benefits and Applications | • Disaster Preparedness: Early warning data for natural disasters. • Infrastructure Monitoring: Tracks structural changes in critical infrastructure. • Environmental and Climate Research: Studies carbon storage, vegetation dynamics, and climate change impacts. |
| Unique Advantages | • Largest collaboration between NASA and ISRO. • Successfully tested in thermal vacuum conditions in Bengaluru in 2023. |
