NISAR Satellite Launch to Boost U.S.-India Space Collaboration and Improve Earth Monitoring

NASA will begin live coverage on Wednesday, July 30, for the launch of the NISAR (NASA-ISRO Synthetic Aperture Radar) satellite, a joint mission between the United States and India designed to scan the Earth’s land and ice-covered surfaces with unprecedented regularity. According to a media advisory from NASA Headquarters, the launch will take place at 8:10 a.m. EDT (5:40 p.m. IST) from the Satish Dhawan Space Centre in southeastern India. The mission aims to provide valuable data that can help scientists and governments monitor infrastructure, agriculture, and environmental changes.

Equipped with dual radar systems from both NASA and the Indian Space Research Organisation (ISRO), the satellite will observe nearly all of Earth’s terrain twice every 12 days. The L-band radar (NASA) and S-band radar (ISRO) will offer high-resolution imaging that can detect even small movements on the planet’s surface. This capability will enhance preparedness and response to natural disasters like hurricanes, floods, and earthquakes, while also supporting crop management and land-use planning. Residents in disaster-prone areas and agricultural regions across the U.S. could benefit directly from this data.

The launch is also seen as a milestone in U.S.-India space relations. President Trump and Prime Minister Modi previously highlighted the mission during a bilateral meeting in February, calling it a major step in strengthening civil space cooperation. With the U.S. segment of the project managed by NASA’s Jet Propulsion Laboratory in California, the collaboration builds on prior efforts such as the Chandrayaan-1 moon mission and recent astronaut partnerships on the International Space Station.

NASA’s launch coverage will begin at 7:00 a.m. EDT on July 30 via NASA+ and the agency’s YouTube channel. A prelaunch teleconference is scheduled for Monday, July 28, featuring key mission leaders and scientists. Media can participate remotely and the public is encouraged to follow and engage via NASA’s social media accounts. The mission’s long-term goal is to improve how communities prepare for and mitigate environmental hazards, potentially reducing both economic damage and human suffering.
