NASA is collaborating with the Indian Space Research Organization (ISRO) for the NISAR mission, as mentioned in the text.

NASA is collaborating with the Indian Space Research Organization (ISRO) for the NISAR (NASA-ISRO Synthetic Aperture Radar) mission. This collaboration between the two space agencies is aimed at developing and launching a dual-frequency synthetic aperture radar satellite.

Collaboration:
- NASA and ISRO signed an agreement in 2014 to collaborate on the NISAR mission. This agreement includes the sharing of scientific data and technical expertise.
- The collaboration between NASA and ISRO for the NISAR mission is a significant step towards strengthening the partnership between the two space agencies.
- The NISAR mission is a joint effort to develop and launch a satellite that will provide valuable data about Earth's land, ice, and ocean ecosystems.

NISAR Mission:
- The NISAR mission aims to provide detailed information about the Earth's surface by using advanced radar imaging techniques.
- The satellite will carry a dual-frequency synthetic aperture radar instrument, which will allow scientists to study changes in Earth's surface with high precision and accuracy.
- The mission will provide crucial data about natural hazards, such as earthquakes, volcanoes, and landslides, and help in monitoring the effects of climate change on Earth's ecosystems.
- The NISAR satellite will orbit the Earth in a polar orbit and collect data continuously, providing a comprehensive view of Earth's surface.

Benefits of Collaboration:
- The collaboration between NASA and ISRO for the NISAR mission brings together the expertise and resources of both space agencies.
- NASA's experience in satellite development and ISRO's expertise in radar technology will ensure the success of the mission.
- The collaboration also allows for the sharing of scientific data, which will benefit researchers and scientists from both countries.
- The NISAR mission will contribute to the global understanding of Earth's ecosystems and help in predicting and mitigating natural disasters.

Conclusion:
The collaboration between NASA and ISRO for the NISAR mission is a testament to the growing partnership between the two space agencies. The mission will provide valuable data about Earth's surface and contribute to our understanding of the planet's ecosystems.
