Theia Labs was founded in 2024 to solve one of space exploration’s most persistent challenges: reliable power when sunlight is not available. The company grew out of an 18-month project during the SpaceTech Master’s program at TU Graz, where the founding team designed a wireless power system to help robotic missions survive the 14-day lunar night.
What began as a lunar survival concept has evolved into a broader mission: building scalable, laser-based wireless power transfer (WPT) solutions for both space and Earth. After presenting the concept at ESA ESTEC in 2023 and joining ESA BIC Austria in 2025, Theia Labs is now developing its first prototype to meet the growing demand for sustainable power in space missions and advanced terrestrial applications.
We develop a laser-based power beaming system to supplement CubeSats’ and SmallSats’ onboard energy in LEO. A dedicated satellite delivers energy to a compact photovoltaic receiver, extending mission lifetimes, reducing battery mass, supporting payloads, and enabling operations during eclipse.
We adapt space-grade WPT technology for sustainable farming. Laser systems target weeds with high precision, minimizing herbicides and supporting healthier soils. This aligns with EU initiatives like the Farm to Fork Strategy and Eco-Schemes to halve pesticide use and expand organic farming by 2030.
For future Moon exploration, Theia Labs is working towards scalable, space-based laser power systems to beam energy from lunar-orbiting satellites to rovers and landers. This technology will enable robotic missions to survive the lunar night and operate in permanently shadowed regions.

We attended SmallSat Europe to engage with the small satellite community and follow the latest developments in satellite platforms, payloads, and mission services. The event also provided opportunities to meet potential customers and explore partnerships relevant to our CubeSat and SmallSat wireless power transfer applications.

We presented Theia Labs’ wireless power transfer concept and outlined our technical roadmap and business needs. The conference brought together space agencies, startups, and established companies, allowing us to exchange insights and explore collaborations that could support technology development and market entry.

Theia Labs was selected for incubation in ESA BIC Austria, based at Science Park Graz. As part of the program, we are developing a breadboard demonstrator of our laser-based wireless power transfer system to validate the core concept using commercial off-the-shelf components, paving the way for future prototype integration.

We presented a poster on our lunar night survival use case, detailing how laser power transfer from orbit can extend the operational lifetime of lunar rovers. The conference connected us with the space-based solar power community and exposed us to a variety of concepts and approaches for space-to-space and space-to-surface energy delivery.
