The ISRO), is set to launch from India in early 2025. Designed to track movements of the Earth's surface, the mission will focus on areas vulnerable to natural hazards, including earthquakes, landslides, and volcanoes. By capturing data on surface shifts down to fractions of an inch, NISAR will provide critical insights into Earth's dynamics, potentially aiding in natural disaster response and infrastructure monitoring.

NISAR's Advanced Monitoring Capabilities 71m1n

As per the official report from NASA, the NiSAR satellite will be equipped with advanced L-band and S-band radar systems. The report mentioned that the satellite will survey nearly all of Earth's land and ice-covered regions twice every 12 days. NASA's Jet Propulsion Laboratory (JPL) in Southern California has developed the L-band radar system, which can penetrate dense vegetation and monitor surface shifts, while ISRO's S-band radar enhances imaging capabilities. Operating continuously, day or night, and unaffected by clouds, NISAR is designed to gather comprehensive data, according to Cathleen Jones, the mission's applications lead at JPL.

The report further mentions that the satellite's ability to reveal subtle ground movement offers a valuable tool for monitoring earthquake-prone areas. Mark Simons, US Solid Earth Science Lead for the project, emphasised that NISAR will not predict earthquakes but could identify regions where faults are locked and more likely to slip.

NISAR's ongoing data collection over time will infrastructure assessment, particularly for dams, levees, and aqueducts. Observing changes in these structures will enable resource managers to detect specific areas requiring closer inspection, reducing the cost and resources needed for manual checks. The Sacramento-San Joaquin River Delta's levees, for example, could be remotely monitored for earthquake-related damages.

Unique Collaboration and Technological Advances 431o6t

This mission, an equal partnership between NASA and ISRO, also marks the first t effort on Earth-observing technology. NASA contributes mission-specific components, including radar systems and communication subsystems, while ISRO oversees the satellite bus, launch services, and mission operations. The mission's data is expected to strengthen understanding of Earth's movements, benefiting global research and infrastructure safety efforts.
