The American Space Agency (NASA) and the Indian Space Research Organization (ISRO) will announce tonight the final details for the launch of the Nisar Mission, an unprecedented land observation satellite that will become the most advanced tool to monitor the effects of climate change.
The launch will occur from the satisfying space center, in southern India, aboard an Indian GSLV MK II rocket that, according to Fuentes de la Iso, is already prepared on the launch ramp.
Developed for more than a decade, Nisar (NASA-Iso synthetic opening radar) is the most expensive land image satellite in the world, with a cost of more than 1.5 billion dollars, and represents a milestone in the spatial collaboration between the United States and India.
Unlike most observation satellites, which depend on sunlight and clear time to take optical images, Nisar uses an advanced synthetic opening radar (SAR).
This technology, similar to using a flash in a dark room, actively sends microwave signals to the surface and captures its reflexes, allowing it to “see” through clouds, smoke and even dense vegetation, according to Isro.

From agriculture to natural disasters: this is what Nisar can detect
Thanks to its huge 12 meter antenna, Nisar will operate day and night and under any meteorological condition. “It will scan virtually the entire earth’s and ice surface on the planet every 12 days with a very high resolution, capable of detecting changes of less than one centimeter,” detail the documents of the mission.
The data collected by Nisar, which will be free access for the world scientific community, will have a direct impact on multiple areas, such as measuring soil moisture to optimize crops and improve food safety, as well as penetrate forests to calculate how much biomass and carbon stores.
For disaster management, this technology is fundamental. It will allow real -time monitoring the movement of glaciers, crucial to study sea level rise, and detect soil deformations that can precede earthquakes and volcanic eruptions, as well as evaluate damage after flooding or landslide.
In this joint mission, NASA has provided the L Radar L, while the ISRO has developed the S band radar and the 2,800 kilograms satellite structure, in addition to taking care of the launch.
