NASA's Lesson for ISRO: The Cost of Silence in Space

The Wake-Up Call from Across the Atlantic

NASA has a blunt message for ISRO: start talking to each other. The advice comes after a near-miss incident involving two Indian satellites last month. The event, which could have resulted in a catastrophic collision, exposed a critical flaw in India's space operations – a breakdown in internal communication.

Senior NASA officials, speaking on condition of anonymity, told Indian counterparts that ISRO's different departments often operate in silos. This lack of coordination, they warned, is a growing risk as India launches more satellites and plans complex missions. The near-collision was a close call that no space agency can afford to ignore.

How a Near-Miss Happened

Details of the incident remain sketchy. ISRO has not officially confirmed the event. But sources within the organisation say two satellites – one for earth observation and another for communication – came within a few hundred metres of each other in low-earth orbit. An emergency manoeuvre was executed to avoid a crash.

The problem, investigators later found, was that the teams operating the two satellites were not sharing trajectory data. One team was unaware of the other satellite's path. The near-collision was discovered by a routine tracking check, not by real-time coordination. The silence could have been deadly – for millions of dollars worth of hardware and for India's reputation in space.

The Growing Risk of Congestion

India's space programme is expanding fast. ISRO now operates over 50 satellites, from weather monitoring to navigation. The Indian government has also approved more private launches. This congestion increases the risk of accidents. NASA learned this lesson the hard way after several close calls involving its own satellites and the International Space Station.

NASA now mandates that all its satellite operators share orbital data through a centralised system. Teams are required to hold regular coordination meetings. ISRO, by contrast, still relies on informal communication between departments. This ad-hoc approach is no longer adequate for the scale of operations India is pursuing.

Cultural Shift Needed, Not Just Technology

The problem is not just technical. It is cultural. ISRO has historically operated in a tight-knit, hierarchical structure. Different centres – such as the UR Rao Satellite Centre in Bengaluru and the Master Control Facility in Hassan – often work independently. This has worked for decades. But with more satellites in orbit and more players in the field, the old ways are becoming dangerous.

NASA's message is clear: invest in communication infrastructure and foster a culture of openness. Share data not just within teams, but across the entire organisation. Create a single point of coordination for all satellite operations. This is not a suggestion. It is a necessity for survival in an increasingly crowded space environment.

What Comes Next for ISRO

ISRO has acknowledged the feedback. Sources say the agency is reviewing its internal protocols. A task force has been set up to study the near-miss and recommend changes. But implementing those changes will take time and political will. India's space budget is already stretched, and adding new communication systems will require significant investment.

For now, ISRO's focus is on damage control. The agency is expected to release a detailed report on the incident in the coming weeks. The question is whether it will also embrace the broader lesson from NASA: that in space, silence is a risk no one can afford.
