Telescope Array Functional Prototype

IN PROGRESS

We are leading the Telescope Array Functional Prototype project to develop a modern, modular astronomical observatory for detecting and monitoring Near-Earth Objects (NEOs). Conducted for the European Space Agency (ESA), it addresses the growing need for precise tracking of asteroids, comets, and other celestial bodies that could threaten Earth. 

Context

Near-Earth Objects—primarily asteroids, but also comets—have been observed since the early 20th century. For decades, discoveries relied on photographic plates; today, advanced cameras and automated observation systems play a central role. The discovery rate has risen dramatically, alongside growing demands for higher accuracy and faster analysis. 

To mitigate potential threats effectively, it is crucial to determine an object’s orbit repeatedly and precisely. Asteroids don’t suddenly appear—they orbit the Sun along elliptical trajectories that can gradually shift due to planetary gravity and other factors. If these shifts bring an object dangerously close to Earth, it becomes a real threat. 

Continuous observation and monitoring of asteroid motion are therefore essential for predicting future trajectories. The more data we collect, the more accurately we can forecast. Importantly, no fully tested method exists for reliably altering the orbit of an asteroid on a collision course with Earth, making early detection and long-term tracking absolutely critical. 

How The Project Addresses These Challenges

The project will create a fully autonomous observation node, featuring: 

• Two 1-meter-class telescopes equipped with cooled, high-sensitivity cameras and a set of movable filters 

• Control infrastructure 

• An automatically opening observation dome 

The telescopes will operate in tandem: 

The first will conduct wide-sky surveys and detect new objects 

The second will perform follow-up observations, calculate orbits for newly discovered bodies, and monitor known objects 

When needed, both telescopes can combine their capabilities, enabling faster sky surveys (by scanning different regions simultaneously) or detecting extremely faint objects (when both focus in the same direction). The system will also allow rapid response to sudden observational needs, including objects moving near Earth—asteroids, comets, rare interstellar visitors, or other fast-moving astronomical phenomena. 

 

A Network, Not A Single Telescope

The dual-telescope observatory will serve as the first node of the planned Telescope Array network. Its architecture is optimized for efficient, scalable expansion. Additional nodes will be strategically placed to cover the largest possible sky area and multiple time zones, enabling continuous observation regardless of Earth’s rotation or location. 

A distributed network of relatively small observatories provides an economical alternative to large, specialized telescopes. Observation tasks are automatically distributed across nodes, reducing survey time and increasing operational flexibility. When necessary, nodes can combine their capabilities to achieve results comparable to larger instruments. 

A key advantage comes from Creotech’s expertise in ultra-precise time synchronization, enabling simultaneous imaging by telescopes worldwide. Combined through specialized algorithms, these images allow detection and localization of objects far fainter than what a single telescope could achieve. 

The network’s rapid response, extensive sky coverage, and efficient large-area scanning also make it well-suited for satellite and space debris monitoring (SST, Space Surveillance and Tracking). In the future, network resources could be shared between SST and Near-Earth Object (NEO) observation tasks.

Creotech Quantum’s Role

A central component of the system will be a new camera developed by Creotech, based on the modular CreoSky6000 platform. Its design allows easy component replacement and customization, making it a proven foundation for solutions requiring: 

• High sensitivity 

• Thermal stability 

• Long-term, reliable operation 

The new camera variant will feature a modern CMOS detector, an enhanced vibration-free cooling system, and software with advanced synchronized multi-camera triggering and built-in astronomical image processing algorithms. 

This solution is expected to become a commercial product, with applications extending well beyond astronomy. 

Challenges

Similar initiatives often take many years to develop. In this case, the full prototype is scheduled for completion in just over a year, making time one of the project’s biggest challenges. The ambitious scope, tight schedule, and potential for network expansion make the Telescope Array Functional Prototype a unique initiative, addressing the urgent need to strengthen global capabilities in NEO monitoring and Earth orbital situational awareness.
