Greece has taken a significant step toward developing a domestic space industry and strengthening its Earth observation capabilities on Tuesday with the successful launch of Hyperion GR-1, the first of seven microsatellites that will form the country’s Hyperion GR satellite constellation.
The satellite lifted off at 10:12 a.m. Greek time (0712 GMT) from Vandenberg Space Force Base in California aboard SpaceX‘s Transporter-17 rideshare mission.
Hyperion GR-1 is part of Greece’s National Microsatellite Program, implemented by the Ministry of Digital Governance and Artificial Intelligence in cooperation with the European Space Agency (ESA) and the Hellenic Space Center, with funding from the EU Recovery and Resilience Facility.
A key feature of the project is that the 100-kilogram satellite was largely designed, assembled and tested at Open Cosmos Aegean’s facilities in Pallini, east of Athens, by a team of local engineers, reflecting the country’s growing ability to manufacture advanced space technology rather than relying solely on foreign-built systems.
Open Cosmos Aegean is responsible for developing, launching and operating seven of the program’s 13 operational microsatellites, while also establishing a ground station in Greece. The company’s investment in its Pallini facilities has created an advanced satellite production center that also serves international customers.
Hyperion GR-1 can capture panchromatic imagery with a ground resolution of 90 centimeters and is equipped with onboard artificial intelligence and inter-satellite communication links, enabling faster processing and transmission of Earth observation data. In some applications, critical information can be delivered within as little as 30 minutes.
The full Hyperion GR constellation will comprise seven satellites with complementary capabilities, including very high-resolution, multispectral and hyperspectral imaging, Automatic Identification System (AIS) ship tracking, Internet of Things (IoT) services and AI-assisted data processing.
The data are expected to support a wide range of public-sector applications, including wildfire and flood monitoring, disaster response, rapid post-event damage assessment, environmental protection, precision agriculture and aquaculture, maritime surveillance, pollution detection and the monitoring of critical infrastructure.
The satellites will also become part of Open Cosmos’ international Open Constellation network, giving Greece access to more frequent Earth observation coverage and faster access to satellite data.
Open Cosmos founder and Chief Executive Officer Rafel Jordà Siquier described the launch as a major milestone for the company, saying the new generation of satellites would enable near real-time Earth observation services to help governments and organizations respond more effectively to natural disasters, security challenges and the protection of critical infrastructure.
Open Cosmos Aegean Managing Director Maria Kalama said the mission demonstrates that Greece is now capable not only of using space technologies but also of designing, manufacturing and exporting them while creating highly skilled jobs and valuable technical expertise.
On his part, Digital Governance and Artificial Intelligence Minister Dimitris Papastergiou described the launch as the beginning of a new era for Greece’s space sector, saying satellite-based Earth observation will strengthen environmental protection, precision agriculture, crisis management and public-sector decision-making. He added that the mission forms part of a broader national strategy to expand the country’s space capabilities, with the planned 350 million-euro HELLAS-SPACE 2.0 program representing the next major phase.
The launch builds on a series of initiatives undertaken over the past six months to establish sovereign space capabilities. Greece has already deployed satellites dedicated to wildfire detection under the National Microsatellite Program and expanded partnerships with the European Space Agency and international aerospace companies to develop domestic satellite manufacturing, Earth observation services and secure space infrastructure. The broader strategy aims to provide the Greek state with independent access to critical geospatial data while fostering a high-value technology sector with export potential.
