Deep Space Energy, a deeptech startup based in Riga, Latvia, was founded in 2022 as a spin-off from the Institute of Physics at the University of Latvia. The company's core mission is to develop and commercialize radioisotope electricity generators for space applications. This technology is designed to convert heat generated by radioisotopes into electrical power, offering a durable and consistent energy source for missions operating in challenging environments.
The primary focus of Deep Space Energy's development efforts is to create a robust power solution suitable for deep space science missions, where solar energy is often limited or unavailable. Additionally, the company is targeting the commercial lunar market, providing power for lunar landers, rovers, and other surface operations. The technology also has potential applications for powering satellites that require extended operational lifetimes or operate in orbits with limited sunlight.
In its early stages, Deep Space Energy has successfully secured pre-seed funding to advance its research and development. The company closed a pre-seed round, raising a total of €930,000. This funding included an initial €350,000, led by Outlast Fund and angel investor Linas Sargautis. These investments are intended to accelerate the development of their radioisotope-based power generator.
Deep Space Energy aims to address the growing demand for reliable and long-lasting power systems in the expanding space economy. By leveraging its expertise in radioisotope technology, the company seeks to enable more ambitious and prolonged space exploration and commercial ventures beyond Earth's orbit.
Deep Space Energy has raised $420K across 1 funding round. Most recently, it raised $420K Deep Space Energy Pre-Seed in February 2026.
