A formidable new radar satellite jointly developed by the United States and India launches, designed to track subtle changes in Earth’s land and ice surfaces and help predict both natural and human-caused hazards. Dubbed NISAR (NASA-ISRO Synthetic Aperture Radar), the pickup truck-sized spacecraft blasted off around 5:40 pm (1210 GMT) from the Satish Dhawan Space Centre on India’s southeastern coast, riding an ISRO Geosynchronous Satellite Launch Vehicle rocket.
