US-Indian Space Mission NISAR Maps Rapid Subsidence in Mexico City
The NISAR satellite, a joint mission by NASA and the Indian Space Research Organisation, has mapped significant subsidence in Mexico City, revealing ground sinking by up to a few centimeters per month. This subsidence is primarily due to extensive groundwater pumping and urban development. The satellite's advanced radar system can track these changes in real-time, providing critical data for infrastructure management. The findings highlight the ongoing challenges faced by Mexico City, one of the fastest-sinking capitals globally, and underscore the importance of space-based monitoring in urban planning and disaster mitigation.
