The NASA–ISRO Synthetic Aperture Radar (NISAR) satellite has successfully unfolded its massive 12-meter-wide radar antenna reflector in orbit—a pivotal moment that transitions the mission from launch to commissioning. With the reflector fully deployed and locked, engineers can now perform critical system checks, calibration, and tuning of its dual-band radar systems (L-band by NASA; S-band by ISRO), vital for capturing high-resolution Earth observations. Once operational, NISAR will begin mapping the entire planet every 12 days, providing real-time data essential for monitoring climate-driven changes, natural disasters, and environmental shifts like glacier melting, land deformation, forest health, and water-cycle dynamics.
