In planetary defence, timing is everything. An alert delayed by hours can mean lost scientific data, slower coordination, and missed observation windows. That is why Infobip has partnered with the European Space Agency (ESA) to upgrade how potential asteroid impact warnings are delivered.

The shift is straightforward but powerful: ESA personnel no longer rely solely on email notifications. Instead, they now receive instant voice calls through Infobip’s Voice API the moment a high-probability impact event is detected. The result is a 24/7 alerting system designed for immediacy, not inbox availability.

For an agency tasked with monitoring near-Earth objects (NEOs), that difference is operationally significant.

Why Near-Earth Objects Demand Instant Response

Asteroids approaching Earth — known as near-Earth objects — are constantly tracked by space agencies worldwide. Most pose no threat. Some require closer monitoring. A very small fraction demand urgent attention.

History reminds us what is at stake. Around 65 million years ago, a single large asteroid impact contributed to the extinction of most life on Earth. Today, planetary defence focuses on early detection, rapid analysis, and coordinated global response.

ESA’s Planetary Defence Office is responsible for analysing asteroid trajectories, determining impact probabilities, and gathering scientific data when events occur. Speed is not just about prevention. It is about precision. The faster teams respond, the faster they can refine trajectory models, mobilise telescopes, and collaborate with international partners.

Previously, ESA alerts were distributed via email. If recipients were offline, asleep, or travelling, delays were inevitable. In a time-sensitive scenario, that friction matters.

From Email Notifications to Real-Time Voice Escalation

By integrating Infobip’s Voice API into ESA’s Meerkat Asteroid Guard system, alerts now trigger automated voice calls to responsible personnel, regardless of time zone or working hours.

Richard Moissl, Head of the European Space Agency’s Planetary Defence Office:

“This new partnership allows us to respond faster and more effectively to potential imminent asteroid impacts, ensuring we collect critical data to better understand these natural threats. Receiving instant alerts has significantly improved our response times and our ability to study these events.”

The change represents a classic evolution in critical communications: detection systems are only as effective as their escalation channels. A notification unseen is a notification wasted. A ringing phone, by contrast, demands attention.

Mirza Hadžić, Sales Director Europe at Infobip, said:

“Infobip’s platform is built to ensure critical communications reach recipients without delay. By enabling ESA to receive instant voice calls, we’re helping them make faster decisions and gather crucial data for planetary defence. This partnership shows how mobile technology and instant messaging apps can support scientific and planetary protection goals.”

Proven in Live Testing

Following a testing phase, the new voice alert system reportedly worked in 100 percent of applicable cases. Two high-probability asteroid impact predictions triggered voice calls within five minutes of detection.

In both instances, the impactors were very small and caused no damage. However, ESA successfully collected valuable scientific data. That alone justifies the shift. In planetary defence, even minor events are research opportunities.

Rapid voice escalation enabled quicker coordination, faster telescope positioning, and more efficient data collection. The takeaway is clear: real-time communication is now part of the defence infrastructure.

CPaaS Moves Into Critical Infrastructure

For Alertify readers, this story is about more than asteroids. It signals a broader shift in how Communications Platform as a Service (CPaaS) providers are embedding themselves into critical infrastructure.

Infobip’s platform claims the ability to reach over seven billion mobile devices globally, supported by more than 800 direct operator connections across six continents. That telecom-grade integration is what enables reliable, low-latency voice delivery at scale.

The CPaaS market itself is expanding rapidly. According to industry analyses from firms such as Gartner and IDC, demand for real-time, multi-channel communication platforms continues to grow as enterprises prioritise resilience, automation, and global reach. Voice remains a core component of high-priority alerting strategies, especially in industries where immediacy outweighs convenience.

ESA’s adoption reflects a maturing market. Rather than building proprietary communication layers, agencies can integrate API-driven voice and messaging systems that scale instantly and operate globally.

Competitive Landscape: Where Infobip Stands

Infobip is not alone in offering programmable voice APIs. Global players such as Twilio and Sinch also operate in the CPaaS space, providing similar voice, SMS, and messaging capabilities.

The differentiation often lies in operator relationships, network depth, and reliability metrics under stress conditions. For mission-critical use cases like planetary defence, redundancy and direct operator connections can outweigh feature breadth.

In this context, ESA’s successful test results — including 100 percent delivery in applicable cases and sub-five-minute escalation times — demonstrate that telecom infrastructure is now trusted in environments where failure is not an option.

That trust is notable. When a space agency responsible for tracking existential risks relies on a commercial cloud communications provider, it signals confidence in the resilience of modern mobile infrastructure.

The Bigger Trend: Real-Time Everything

Across industries, the same pattern is emerging. Aviation, maritime safety, industrial IoT, cybersecurity operations, and enterprise travel risk management are all moving toward automated detection systems paired with instant, multi-channel escalation.

Email is becoming a secondary layer. Push notifications are supplementary. Voice remains the highest-priority trigger when human intervention is required immediately.

ESA’s move aligns with that trajectory. Detection technology for NEOs continues to improve through global telescope networks and advanced modelling. But detection without rapid human activation creates bottlenecks.

The real innovation here is not the asteroid tracking algorithm. It is the removal of delay between detection and decision.

Conclusion

This partnership between Infobip and ESA illustrates a broader transformation in how critical systems communicate. Planetary defence may sound exceptional, but the underlying principle applies universally: detection must be matched by instantaneous escalation.

Compared with other CPaaS providers in the market, Infobip’s strength lies in deep operator integration and global telecom reach — capabilities that appear to have met ESA’s stringent reliability requirements. Industry reports from Gartner and IDC consistently highlight reliability, redundancy, and low-latency delivery as key differentiators in high-stakes communication environments.

The future of resilience — whether in space monitoring, aviation safety, or global enterprise operations — will not depend solely on smarter sensors or better predictive models. It will depend on whether the right people are reached immediately when anomalies are detected.

In that sense, this is not just a telecom partnership. It is an example of how cloud communications infrastructure is quietly becoming part of the planet’s safety architecture.
