| Key Highlights of NISAR |
SRO and NASA have a joint venture to build a NISAR satellite which is a NASA and Indian Space Research Organization (ISRO) collaboration. Its launch is expected in March 2025. NISAR will be designed as a satellite for high-resolution on- and off-wave observation with radar technology that is advanced and vital for data concerning the Earth's surface.
1. "Mission Objective" The NISAR satellite will have an image about the earth as to its natural phenomena (like earthquakes, tsunamis, and volcanic eruptions) and human-induced changes (such as deforestation and urbanization). It will also give observers an understanding of other important aspects of climate change, such as ice dynamics at the poles, sea-level rise, and forest cover.
2. "Technology": NISAR, two systems of synthetic aperture radar (SAR), one operating at L-band by NASA and the other one at S-band by ISRO, will be described. These radar systems will permit the satellite to represent a high-resolution surface of the Earth, even in conditions of cloud or low light in different areas.
3. "Cooperation": One possible explanation for the mission is that it is not only a very good cooperation in the scientific spheres but also in the political area, with the combination of ISRO's knowledge of the space system and technology for satellites with that of NASA's in radar science or Earth observation. That's an enormous headway in the way the world cooperates in the monitoring of Earth from space.
4. "Mission Lifetime" The satellite is designed to operate for a minimum period of three years during which repeated data collection will be carried out along the whole mission period.
5. "Orbit and Coverage" NISAR is the kind of satellite that will be stationed at a "polar orbit because it gives the whole surface of the Earth some coverage based on a temporal cycle. It is something like having one fantastic world-level dataset in a High-Resolution Imaging Mode taken for scientists and researchers to tool around with.
The mission is expected to also raise the level of knowledge of our world about the ever-changing environment of the Earth and make significant contributions to fields like disaster management.
