What's Happening?
NASA and the Indian Space Research Organisation (ISRO) have launched the NISAR satellite, a groundbreaking mission aimed at monitoring Earth's surface changes. The satellite features the largest radar antenna ever used in a NASA mission, designed to detect minute movements in the planet's crust. This collaboration between NASA and ISRO marks a significant advancement in geoscience, providing detailed 3D imaging capabilities. The satellite was launched from India's Satish Dhawan Space Centre on July 30, 2025, and has successfully deployed its massive radar antenna over a four-day period. NISAR's dual synthetic aperture radar systems allow for high-resolution imaging under various conditions, enabling scientists to create detailed three-dimensional images of Earth's surface changes.
