Mission Drishti, the world's first OptoSAR satellite and the largest earth observation system satellite made by the Indian private sector to date, has lost communication with ground stations, according to sources familiar with the mission.
Satellite Details and Mission Objectives
The satellite was developed by a consortium of Indian private companies and research institutions. It combined optical and synthetic aperture radar (SAR) imaging capabilities, allowing it to capture high-resolution images day and night, regardless of weather conditions. The satellite weighed approximately 1,200 kilograms and was launched aboard a SpaceX Falcon 9 rocket in early 2026.
Mission Drishti was intended to provide critical data for agriculture, urban planning, disaster management, and defense surveillance. It was equipped with advanced sensors capable of resolving objects as small as 0.5 meters from an altitude of 600 kilometers.
Communication Loss and Response Efforts
The loss of communication was first detected on July 5, 2026, when the satellite failed to respond to routine telemetry commands from the Indian Space Research Organisation's (ISRO) ground station in Bengaluru. Subsequent attempts to re-establish contact over the next 48 hours were unsuccessful.
According to an official from the Indian National Space Promotion and Authorization Centre (IN-SPACe), “We are working closely with the satellite operators to diagnose the issue. Preliminary analysis suggests a possible failure in the onboard communication subsystem, but we have not ruled out other causes such as a power system anomaly or a collision with space debris.”
Impact and Future Implications
The loss of Mission Drishti is a significant setback for India's private space sector, which has been gaining momentum with government reforms aimed at boosting commercial space activities. The satellite was insured for approximately ₹400 crore (about $48 million), and claims are expected to be filed soon.
Industry experts say the incident highlights the risks inherent in space missions, especially for complex, first-of-their-kind satellites. However, they also note that the lessons learned from Mission Drishti will inform future projects. “This is a tough blow, but it’s not the end. The technology developed for Drishti will be reused in upcoming missions,” said a senior executive at one of the consortium companies.
ISRO has formed a committee to investigate the anomaly and provide recommendations for future satellite programs. The agency continues to track the satellite's orbit and is monitoring for any signs of a revival of communication.
