NASA and India launch satellite to monitor Earth's land and ice changes

In a remarkable collaboration between the United States and India, the NISAR satellite was launched to monitor Earth's land and ice changes. This satellite operates from an orbit 464 miles high, and through its dual radar system, it is designed to measure changes as minor as a centimeter, essential for predicting natural disasters such as floods and landslides. The satellite's mission, which costs $1.3 billion and is backed primarily by NASA, is expected to significantly enhance disaster preparedness. The satellite incorporates technology from both nations, with NASA primarily responsible for the low-frequency radar. Scientists expect the NISAR satellite to operate effectively by the end of October, after its 30-foot boom is extended and its reflector is deployed. It will conduct observations of Earth multiple times every 12 days, enabling accurate assessments of glacial melting, groundwater shifts, and surface motion. This is aimed at better understanding phenomena that contribute to climate change and increase natural disaster risks. The satellite is not only a major technological venture but also signifies the most extensive space collaboration to date between the two nations. The satellite's advanced capabilities allow it to observe the planet even in adverse weather conditions, which is crucial for timely forecasting. This level of detailed earth observation is expected to revolutionize the study of natural events and aid in early disaster management and environmental monitoring practices around the globe. Researchers involved in the project have emphasized that this mission could change both how scientists study our planet and how responders manage disasters. The information gathered will help in predicting phenomena that contribute to increased carbon emissions and overall climate change, bringing together international resources to address pressing global environmental issues.
