• Recognition: Launch praised by Prime Minister Narendra Modi as a major milestone in India's space journey

Background & Context

Traditional Earth observation satellites either use Electro-Optical (EO) sensors, capturing images in visible and infrared wavelengths, or Synthetic Aperture Radar (SAR), which uses microwave radar to image through clouds and darkness. EO sensors provide intuitive visual clarity but are limited by weather and lighting conditions, while SAR provides all-weather capability albeit with imagery that is harder to interpret.

Mission Drishti introduces OptoSAR technology that co-locates high-resolution SAR and a 7-band multispectral imager on a single satellite platform, capturing both types of data simultaneously in a single pass. This eliminates the need for data fusion from separate sensors on multiple satellites, providing inherently aligned, analysis-ready data with up to three times more actionable information than standalone sensors.

The development involved over five years of R&D by GalaxEye, reflecting the maturity and growing capabilities of India’s private space tech sector. The successful launch aboard a SpaceX Falcon 9 rocket underscores global collaborations enabling faster, flexible, cost-effective access to space for Indian startups.

Why This Matters for Exams / Exam Relevance

Mission Drishti is an important contemporary topic in India’s science and technology advancements, particularly highlighting the private sector’s contribution to space technology. Competitive exams may ask about:

• The significance of OptoSAR technology and its advantages over traditional EO or SAR satellites
• The role of private startups like GalaxEye in India’s space ecosystem
• The applications of Earth observation satellites in defense, agriculture, disaster management, maritime security, and infrastructure
• Details of satellite launch including launch vehicle (SpaceX Falcon 9) and launch site (Vandenberg, California)
• The collaboration between ISRO/NSIL and private players

Understanding this topic also provides insight into the evolving global satellite imaging market and India’s emerging position within it.
