A Revolutionary Eye in the Sky
Launched in May 2026, Mission Drishti represents a major technological milestone. Developed by Bengaluru-based startup GalaxEye, it is the world's first satellite to feature OptoSAR technology. This innovation combines a traditional optical camera with
a Synthetic Aperture Radar (SAR) on a single platform. Optical sensors provide clear, detailed images, much like a regular camera, but are rendered useless by clouds, smoke, or darkness. SAR, on the other hand, can pierce through these obstacles, providing imagery day or night, in any weather condition. By fusing these two capabilities, OptoSAR was designed to offer the best of both worlds: the clarity of optical images with the all-weather reliability of radar, a game-changer for a country that frequently experiences heavy monsoon cloud cover.
A Mission of National Importance
As India's largest privately developed Earth observation satellite, the 190 kg Mission Drishti had significant strategic goals. Its primary purpose was to provide consistent, high-quality data for both civilian and defence applications. For national security, the satellite’s ability to see through clouds and darkness offered unprecedented surveillance capabilities for border monitoring. In the civilian sector, it was poised to revolutionize disaster management by tracking floods, cyclones, and forest fires in real-time, even through thick cloud cover. It also held immense promise for agriculture, infrastructure planning, and monitoring climate change, reducing India's reliance on foreign satellite data providers.
Nature's Fury Unleashed
The adversary that struck Mission Drishti was a geomagnetic storm, a powerful eruption from the Sun. These storms occur when the Sun releases massive bursts of energy and charged particles, known as coronal mass ejections (CMEs). While Earth's magnetic field protects the planet's surface, satellites in orbit are far more vulnerable. In early July, a series of strong solar flares erupted from the sun, sending clouds of plasma hurtling towards Earth. When these energetic particles slam into a satellite, they can cause a host of problems, from software glitches and phantom commands to catastrophic hardware failure due to radiation damage or electrical charging.
Assessing the Impact
According to a statement from GalaxEye on July 7, Mission Drishti encountered the anomaly during the final stage of its Launch and Early Orbit Phase (LEOP). The company reported that the satellite had successfully established communication and performed several key manoeuvres after its launch. However, following the geomagnetic storm, communication became intermittent before being lost entirely. An initial analysis suggests that radiation effects from the solar event likely impacted a critical onboard system. While recovery efforts are underway from the mission control centre in Bengaluru, the company has stated that the likelihood of re-establishing contact appears low, putting the groundbreaking mission in serious jeopardy.
A Setback, Not a Defeat
The potential loss of Mission Drishti is a significant blow to India's burgeoning private space industry. However, the mission has already provided invaluable data. During its few weeks of operation, it successfully validated the critical technologies and operational expertise needed to build and manage such advanced space systems. GalaxEye has affirmed that the engineering insights gained will directly strengthen its future missions. The company has already announced plans to launch two more OptoSAR satellites within the next two years, demonstrating resilience in the face of this setback. This incident serves as a stark reminder of the inherent risks of space exploration, where even the most advanced technology remains subject to the immense power of the cosmos.
