Riga-based SpaceTech startup Deep Area Power has raised a complete €930k to additional develop a radioisotopic generator towards commercialisation, in a bid to strengthen the European sovereign house and protection business and energy Moon floor exploration.
The funding was made up of its €350k pre-Seed spherical led by Outlast Fund and Linas Sargautis, an angel investor and a former co-founder of NanoAvionics. The corporate additionally secured further €580k in public contracts and grants by the European Area Company (ESA), NATO DIANA, and the Latvian authorities.
“Our know-how, which has already been validated within the laboratory, has a number of purposes throughout the defence and house sectors. First, we’re growing an auxiliary vitality supply to boost the resilience of strategic satellites. It supplies the redundancy of satellite tv for pc energy methods by supplying backup energy that doesn’t depend upon photo voltaic vitality, making it essential for high-value army reconnaissance belongings,” says Mihails Ščepanskis, founder and CEO of the corporate.
Within the 2025–2026 interval, EU-Startups has reported substantial capital flows into the European SpaceTech sector, primarily at Seed and Collection A stage.
Germany’s Reflex Aerospace secured €50 million to scale sovereign satellite tv for pc platforms, whereas France’s Infinite Orbits raised €40 million to increase in-orbit servicing capabilities. Additionally in France, Look Up attracted €50 million to develop its radar-based house surveillance community, and UNIVITY secured €31 million to speed up improvement of a space-based 5G constellation.
In Germany, Marble Imaging raised €5.3 million to scale its very excessive decision Earth remark satellites forward of launch, whereas Spain’s Kreios Area secured €8 million to advance propulsion methods for very low Earth orbit. Italy’s Astradyne raised €2 million to commercialise ultralight photo voltaic panels, and Spain’s Orbital Paradigm closed a €1.5 million pre-Seed spherical to develop reusable house capsules.
Collectively, these rounds symbolize roughly €187 million in disclosed funding transferring into European SpaceTech throughout adjoining segments together with satellite tv for pc infrastructure, propulsion, communications, servicing and remark.
Towards this backdrop, Deep Area Power’s €930k elevate positions it at an earlier proof-of-concept stage inside the ecosystem, with a give attention to vitality resilience for satellites and lunar missions quite than platform deployment.
“As Europe is attempting to turn into extra impartial, it’s crucial to supply satellites with superior capabilities on our personal. Our know-how supplies an auxiliary vitality supply for satellites, which makes them extra resilient to non-kinetic assaults and malfunctions,” Mihails provides.
Based in 2022, Deep Area Power is growing a brand new radioisotope energy generator for house that makes use of the warmth produced by the nuclear self-decay of radioisotopes – supplies extractable from waste of business nuclear reactors.
The product goals for purposes in deep house science missions, lunar floor missions and high-value protection satellites. Their answer converts that warmth into electrical energy, requiring 5 occasions much less radioisotope gas than a thermo-electric generator (RTG), presently utilized in house.
The corporate highlighted that its radioisotope-based vitality generator shouldn’t be designed for any form of weapons. It’ll goal high-value, dual-use satellites to extend their resilience and operational reliability. The first focus is on satellites working in Medium Earth Orbit (MEO), Geostationary Orbit (GEO) and Extremely Elliptical Orbit (HEO), that are all important for contemporary army reconnaissance and early-warning methods.
These satellites help a spread of defence features, from artificial aperture radar (SAR)
satellites for detecting troop concentrations by means of clouds and foliage, to sign intelligence for intercepting communications and radio transmissions, in addition to missile-launch detection, which is important for anti-missile protection methods.
Mihails says that the continued struggle in Ukraine clearly demonstrated the decisive function of satellite-based reconnaissance information for contemporary warfare. In 2025, Ukraine misplaced its beachhead in Russian Kursk Oblast at a time when the US quickly terminated the sharing of satellite tv for pc intelligence.
This highlights the strategic significance of satellite-based reconnaissance information and likewise signifies the strategic vulnerability of Europe, which largely depends on the US defencs house belongings, particularly for high-value GEO satellites.
Egita Poļanska, associate on the lead investor Outlast Fund, shares: “Area vitality tech has been caught with sure limitations for many years, however we’re lastly seeing the items come collectively for an actual breakthrough – new supplies, smarter energy methods, and precise business demand for lunar operations.
“Deep Area Power is constructing the infrastructure that may actually energy the following chapter of house exploration and business. As Europe ramps up its house ambitions, we want our personal firms to steer in these foundational applied sciences. We’re thrilled to again this staff and actually fairly excited to have an precise moonshot in our portfolio, in essentially the most literal sense doable.”
In the long run, the corporate goals to give attention to the Moon economic system. The radioisotope energy generator appears to handle important vitality challenges within the subsequent section of lunar exploration, together with NASA and ESA’s Artemis, Argonaut and lunar rover programmes, in addition to the Moon Village framework. Specifically, the know-how is designed to help lunar evening survival and operations in completely shadowed areas, enabling prolonged scouting and prospecting missions.
On the Moon, the place the temperatures at evening drop beneath 150 levels Celsius, and nights final for roughly 354 hours, moonrovers can’t depend on solar energy.
The corporate’s know-how requires roughly 2kg of Americium-241 gas to generate 50W of energy for a lunar rover, in contrast with round 10kg of radioisotope materials wanted by legacy RTG methods for comparable output. Given present projections that Americium-241 manufacturing capability will attain round 10kg per 12 months by the mid-2030s, this effectivity may allow lunar exploration missions to start greater than 5 years earlier and at as much as 5 occasions the mission quantity.
Because of this, business lunar actions and useful resource utilisation may emerge considerably prior to beforehand anticipated.
In line with Ščepanskis, the corporate’s know-how can considerably improve the economics of moon rover missions by enabling them to final a number of day-night cycles up to a couple years. The only bills of bringing payload to the Moon value as much as one million euros per kilogram; thus, by enhancing the lifetime of the rovers, the corporate helps to save lots of a whole bunch of thousands and thousands.
Linas Sargautis provides: “The Baltic area is more and more recognised for its innovation in house know-how, with Deep Area Power serving as one other robust instance. By supporting Deep Area Power, we’re serving to to ascertain a stable basis for the way forward for house frontier exploration, comparable to lunar and deep-space missions, increasing humanity’s information and footprint, whereas additionally contributing to European house defence capabilities.
“I’m proud to help the corporate’s journey by strengthening the staff’s connections with main house methods integrators, in addition to supporting the corporate’s enlargement and contracting plans to construct the mandatory experience on the subsystem integration stage.”
