European firms secure major funding for radioisotope generators and LEO satellites, advancing space independence and mission capabilities amid global competition.
Deep Space Energy’s €930K pre-seed round and Eutelsat’s €975M financing drive Europe’s push for self-reliant space tech, targeting lunar exploration and global connectivity markets.
Europe’s strategic leap in space energy
In 2025, Europe’s space industry is accelerating its sovereignty efforts through innovative energy and connectivity solutions. Deep Space Energy, a startup specializing in radioisotope power systems, announced in a press release that it secured a €930,000 pre-seed funding round. This investment, led by Outlast Fund and angel investor Linas Sargautis, supports the development of a generator five times more efficient than traditional Radioisotope Thermoelectric Generators (RTGs), using Americium-241 derived from nuclear waste. CEO Dr. Mihails Ščepanskis stated, “This technology is crucial for Europe’s defense and exploration goals, especially in light of vulnerabilities exposed during recent conflicts like the war in Ukraine.” The generator aims to power defense satellites and lunar rovers, with contracts from the European Space Agency (ESA) and NATO’s DIANA program, highlighting public-private partnerships fueling innovation.
Connectivity expansion with Eutelsat’s satellite surge
Parallel to energy advancements, Eutelsat has secured €975 million in Export Credit Agency financing, backed by the French state via Bpifrance Assurance Export, as detailed in an announcement from the company. This funding facilitates the procurement of 340 new Low-Earth Orbit (LEO) satellites from Airbus, ensuring continuity for the OneWeb constellation. Jean-Francois Fallacher, CEO of Eutelsat OneWeb, noted in a company blog, “This investment reduces Europe’s dependency on U.S. assets and strengthens our position in global connectivity markets.” The expansion targets enhanced satellite resilience for critical sectors, including government services and mobile connectivity, with job creation expected in Toulouse, France. According to TechFundingNews, this move addresses growing demand for low-latency connectivity, supporting Europe’s digital economy and strategic independence.
Analytical implications for Europe’s space future
The dual trends in energy and connectivity underscore Europe’s broader push for space sovereignty. Deep Space Energy’s generator could save hundreds of millions in payload costs for lunar missions by powering rovers during the Moon’s 14-day night, a point emphasized in ESA’s Argonaut mission plans. Similarly, Eutelsat’s LEO network aims to compete with global players like SpaceX’s Starlink, reducing geopolitical risks. Market analysts, cited in industry reports, project that Europe’s space economy could grow by 10% annually, driven by such innovations. The integration of these technologies supports ambitious collaborations, such as with NASA’s Artemis program, positioning Europe as a key player in high-stakes space environments.
Looking back, Europe’s current space initiatives build on precedents like the Galileo satellite navigation system, launched in the early 2000s to reduce reliance on U.S. GPS. That project demonstrated how sovereign space infrastructure can enhance economic and security benefits, similar to today’s energy and connectivity efforts. Additionally, the development of Ariane rockets in the 1970s set a foundation for independent launch capabilities, mirroring the strategic investments seen now. These historical examples show that Europe has consistently pursued space autonomy through technological leaps, with current trends accelerating this legacy to meet modern challenges like lunar exploration and digital sovereignty.
