ORiS, an Italian startup, has secured funding to develop laser power-beaming technology for space applications. The company aims to transmit energy wirelessly from ground stations to orbiting spacecraft using focused laser beams, eliminating the need for conventional solar panels or battery constraints.
Laser power beaming addresses a fundamental bottleneck in space operations. Satellites and orbital vehicles depend on finite power sources that degrade performance during eclipse periods or when operating far from the sun. By transmitting energy as coherent light from Earth, ORiS envisions spacecraft that operate continuously with sustained power levels independent of orbital position or solar intensity.
The technology holds particular value for deep-space missions, lunar operations, and long-duration satellite constellations. A spacecraft receiving laser-transmitted power could maintain full operational capacity throughout its orbit without the weight penalty of oversized battery banks or the efficiency losses of traditional solar arrays. For missions to Mars or beyond, ground-based power transmission could supplement onboard systems during critical phases.
ORiS joins a growing field of companies and research institutions pursuing space-based power transmission. The technology requires solving substantial engineering challenges, including atmospheric interference, beam pointing accuracy across distances of hundreds of kilometers, and receiver efficiency in the vacuum environment. Ground control systems must track moving spacecraft with precision measured in meters at orbital velocities.
The company's funding round reflects investor confidence in the commercial potential of wireless power transmission. As space traffic intensifies and mission durations extend, alternative power solutions become economically attractive. Reusable launch vehicles and expanding constellation networks create demand for technologies that reduce spacecraft mass and extend operational lifespans.
ORiS positions itself within Europe's growing space technology sector, competing with international efforts to commercialize power beaming. Success in this domain could reshape how future spacecraft operate, particularly for applications requiring continuous high power output in environments where solar generation proves insufficient or unreliable.
