NASA and India’s space agency, ISRO, have made history. Together they deployed the world’s largest radar antenna in space under the NISAR mission. This breakthrough will help scientists study Earth in powerful new ways.
The radar antenna is 12 meters wide. It unfolded in orbit and is now ready for use. It can capture detailed images of Earth’s surface, even at night or through clouds. Using two radar frequencies—L-band from NASA and S-band from ISRO—NISAR will monitor earthquakes, melting glaciers, forest changes, and floods.
The project highlights the power of international teamwork. Engineers in both countries spent years designing the antenna to unfold safely in space.
Data from NISAR will be shared with scientists and governments worldwide. It will help track climate change, manage disasters, and protect natural resources.
Full operations will begin in 2026. Experts believe NISAR will change the way we study Earth and provide better tools to care for the planet.
