University of Tartu's deep-space camera OPIC set to capture solar system's oldest secrets

After eight years of development, Estonian scientists at the University of Tartu Observatory have completed OPIC, Estonia's first deep-space camera. The device has been handed over to the European Space Agency and will form part of the unprecedented 'Comet Interceptor' mission, aiming to photograph a comet carrying 4.6-billion-year-old data about the birth of our Solar System.

Scientists at the University of Tartu Observatory have completed a landmark achievement in Estonian space research — the country's first deep-space camera, named OPIC, has been finalised and officially handed over to the European Space Agency (ESA). The milestone caps eight years of intensive development work and marks Estonia's most ambitious contribution to space exploration to date.

## What is the Comet Interceptor mission?

OPIC will play a central role in ESA's groundbreaking 'Comet Interceptor' mission, which aims to photograph a comet at close range for the very first time. The target comets are believed to carry material dating back approximately 4.6 billion years — essentially frozen remnants from the formation of our Solar System. By capturing detailed images of such a comet, scientists hope to unlock clues about the origins of planets, water, and potentially life itself.

## Eight years in the making

The camera's development at the University of Tartu Observatory was a demanding engineering and scientific undertaking, stretching across nearly a decade. The project required cutting-edge optical and imaging technology capable of surviving the harsh conditions of deep space while delivering high-resolution imagery of a fast-moving celestial body. The successful handover to ESA represents not only a technical triumph but also a significant step forward for Estonia's growing presence in the international space sector.

Estonia joined ESA as a full member state in 2015, and since then Estonian research institutions and technology companies have steadily expanded their involvement in European space programmes. OPIC and the Comet Interceptor mission represent arguably the highest-profile contribution from Estonian scientists so far, placing the University of Tartu among the select group of institutions contributing hardware to ESA's deep-space exploration efforts.
