Nisar Satellite Captured in “Full Bloom” with Giant Radar Antenna in Space

The NASA-ISRO Synthetic Aperture Radar (Nisar) satellite has been captured in stunning detail, described as “full bloom”, by Vantor. This unprecedented image reveals the satellite’s giant circular radar antenna reflector, deployed successfully in August 2025.

Nisar, the most advanced radar satellite of its kind, is a joint mission between NASA and ISRO, designed to provide high-resolution radar imaging of Earth’s surface. Its mission includes tracking shifting ice sheets, earthquakes, forest cover, and crop conditions, revolutionizing environmental monitoring.

The satellite’s reflector, measuring 12 meters (39 feet) in diameter, is the largest radar antenna ever deployed in space. It was folded like an umbrella for launch before fully deploying in orbit. Vantor’s image not only confirms proper deployment but also verifies spacecraft orientation, antenna tensioning, and velocity, crucial for managing high-value space assets.

Equipped with a dual-band synthetic aperture radar system combining L-band and S-band radar, Nisar can scan Earth’s land and ice-covered surfaces every 12 days, delivering unparalleled detail. Its data promises to enhance disaster response, infrastructure monitoring, agricultural management, and climate research worldwide.

The mission exemplifies a milestone in global scientific collaboration, leveraging the expertise of NASA and ISRO to achieve transformational Earth observation capabilities. The clarity of Vantor’s image reflects the satellite’s potential to provide reliable intelligence for monitoring both natural and human-induced changes on Earth.

Nisar’s “full bloom” image marks a new era in space imaging, showcasing an engineering marvel in orbit and heralding impactful scientific discoveries for planetary management and disaster preparedness.
