Discover what the future holds for our planet with the upcoming launch of NISAR. Set to revolutionize Earth observation, this innovative satellite is a collaboration between NASA and ISRO, scheduled for launch in March 2025.
NISAR, a satellite weighing 2.8 tonnes and costing ₹5,000 crores, will embark on its mission from the Satish Dhawan Space Centre in Sriharikota, India, soaring into a sun-synchronous orbit at an altitude of 747 kilometers. This groundbreaking mission, conceived in 2009, marks a significant milestone in the longstanding partnership between the two space agencies, building upon a decade of collaborative advancements.
Equipped with cutting-edge Synthetic Aperture Radar (SAR) technology, NISAR will provide unparalleled imaging capabilities. Unlike conventional satellites, NISAR can operate through darkness and adverse weather, enabling it to gather critical data from nearly every part of the Earth’s surface twice every 12 days. By incorporating dual-frequency radars, NISAR balances comprehensive penetration and high-resolution imaging, boasting a remarkable 240-km swath width with an impressive 10-meter resolution.
NISAR’s applications are expansive—ranging from enhanced climate studies and disaster response to infrastructure monitoring and geological assessments. The satellite is expected to produce an astonishing 26 terabits of data each day, providing invaluable insights for scientists and policymakers alike. Despite earlier technical obstacles, the NISAR mission is poised for a successful launch, heralding a new era in Earth observation technology.
