With Europe seeking greater defense and space autonomy, Deep Space Energy secures €930k to advance lunar energy tech

Riga-based SpaceTech start-up Deep Space Energy has actually elevated a complete EUR930k to additional create a radioisotopic generator towards commercialisation, in a proposal to reinforce the European sovereign area and protection market and power Moon surface area expedition.

The financing was comprised of its EUR350k pre-Seed round led by Outlast Fund and Linas Sargautis, an angel capitalist and a previous founder of NanoAvionics. The business likewise protected added EUR580k in public agreements and gives by the European Room Firm (ESA), NATO DIANA, and the Latvian federal government.

“ Our modern technology, which has actually currently been confirmed busy, has numerous applications throughout the support and area industries. Initially, we’re creating a supporting power resource to boost the durability of critical satellites. It gives the redundancy of satellite power systems by providing back-up power that does not depend upon solar power, making it critical for high-value army reconnaissance properties,” states Mihails Ščepanskis, owner and chief executive officer of the business.

In the 2025– 2026 duration, EU-Startups has actually reported significant funding moves right into the European SpaceTech field, mostly at Seed and Collection A phase.

Germany’s Reflex Aerospace protected EUR50 million to scale sovereign satellite systems, while France’s Infinite Orbits elevated EUR40 million to increase in-orbit maintenance abilities. Likewise in France, Look Up brought in EUR50 million to expand its radar-based area monitoring network, and UNIVITY protected EUR31 million to speed up growth of a space-based 5G constellation.

In Germany, Marble Imaging elevated EUR5.3 million to scale its really high resolution Planet monitoring satellites in advance of launch, while Spain’s Kreios Space protected EUR8 million to progress propulsion systems for really reduced Planet orbit. Italy’s Astradyne elevated EUR2 million to commercialise ultralight photovoltaic panels, and Spain’s Orbital Paradigm shut a EUR1.5 million pre-Seed round to create recyclable area pills.

Jointly, these rounds stand for about EUR187 million in revealed financing relocating right into European SpaceTech throughout surrounding sectors consisting of satellite facilities, propulsion, interactions, maintenance and monitoring.

Versus this background, Deep Room Power’s EUR930k raising placements it at an earlier proof-of-concept phase within the environment, with a concentrate on power durability for satellites and lunar goals instead of system implementation.

“ As Europe is attempting to come to be a lot more independent, it is essential to generate satellites with sophisticated abilities on our very own. Our modern technology gives a supporting power resource for satellites, that makes them a lot more durable to non-kinetic strikes and breakdowns,” Mihails includes.

Established In 2022, Deep Room Power is creating a brand-new radioisotope power generator for area that utilizes the warmth generated by the nuclear self-decay of radioisotopes– products extractable from waste of industrial atomic power plants.

The item goes for applications in deep area scientific research goals, lunar surface area goals and high-value protection satellites. Their remedy transforms that warmth right into electrical power, calling for 5 times much less radioisotope gas than a thermo-electric generator (RTG), presently made use of precede.

The business highlighted that its radioisotope-based power generator is not developed for any kind of type of tools. It will certainly target high-value, dual-use satellites to boost their durability and functional integrity. The main emphasis gets on satellites running in Tool Planet Orbit (MEO), Geostationary Orbit (GEO) and Extremely Elliptical Exerciser Orbit (HEO), which are all crucial for contemporary army reconnaissance and early-warning systems.

These satellites sustain a variety of support features, from artificial aperture radar (SAR)
satellites for discovering army focus via clouds and vegetation, to indicate knowledge for obstructing interactions and radio transmissions, in addition to missile-launch discovery, which is necessary for anti-missile protection systems.

Mihails states that the recurring battle in Ukraine plainly showed the crucial function of satellite-based reconnaissance information for contemporary war. In 2025, Ukraine shed its beachhead in Russian Kursk Oblast at once when the United States momentarily ended the sharing of satellite knowledge.

This highlights the critical value of satellite-based reconnaissance information and likewise shows the critical susceptability of Europe, which mostly counts on the United States defencs area properties, specifically for high-value GEO satellites.

Egita Poļanska, companion at the lead capitalist Outlast Fund, shares: “ Room power technology has actually been stuck to particular restrictions for years, however we’re ultimately seeing the items collaborated for a genuine advancement– brand-new products, smarter power systems, and real industrial need for lunar procedures.

” Deep Room Power is constructing the facilities that will actually power the following phase of area expedition and market. As Europe increases its area passions, we require our very own business to lead in these fundamental modern technologies. We’re enjoyed back this group and truthfully quite thrilled to have a real moonshot in our profile, in one of the most actual feeling feasible“

In the long-term, the business intends to concentrate on the Moon economic situation. The radioisotope power generator wants to deal with crucial power obstacles in the following stage of lunar expedition, consisting of NASA and ESA’s Artemis, Argonaut and lunar vagabond programs, in addition to the Moon Town structure. Specifically, the modern technology is developed to sustain lunar evening survival and procedures in completely trailed areas, allowing extensive searching and prospecting goals.

On the Moon, where the temperature levels in the evening decrease listed below 150 levels Celsius, and evenings last for about 354 hours, moonrovers can not rely upon solar energy.

The business’s modern technology calls for about 2kg of Americium-241 gas to create 50W of power for a lunar vagabond, compared to around 10kg of radioisotope product required by heritage RTG systems for equivalent result. Offered existing estimates that Americium-241 manufacturing ability will certainly get to around 10kg annually by the mid-2030s, this effectiveness might make it possible for lunar expedition goals to start greater than 5 years previously and at approximately 5 times the goal quantity.

Consequently, industrial lunar tasks and source exercise might arise dramatically earlier than formerly anticipated.

According to Ščepanskis, the business’s modern technology can dramatically boost the business economics of moon vagabond goals by allowing them to last several day-night cycles approximately a couple of years. The single costs of bringing haul to the Moon set you back approximately a million euros per kg; therefore, by improving the life time of the vagabonds, the business assists to conserve thousands of millions.

Linas Sargautis includes: “ The Baltic area is progressively identified for its advancement precede modern technology, with Deep Room Power acting as one more solid instance. By sustaining Deep Room Power, we are assisting to develop a strong structure for the future of area frontier expedition, such as lunar and deep-space goals, broadening humankind’s expertise and impact, while likewise adding to European area support abilities.

“ I am honored to sustain the business’s trip by reinforcing the group’s links with leading area systems integrators, in addition to sustaining the business’s growth and having strategies to construct the essential experience at the subsystem assimilation degree.“
