Q1. The Ministry of Home Affairs on 3 May 2026 said GalaxEye's Mission Drishti is the world's first OptoSAR satellite. What does the OptoSAR concept combine, and what is its other distinction?
Explanation
The release described Mission Drishti as combining optical cameras with all-weather Synthetic Aperture Radar for Earth observation, and as India's largest privately built satellite. Hyperspectral, thermal-acoustic and GNSS combinations are not the OptoSAR concept.
