Recent developments in space-based energy infrastructure are accelerating, with major advances in orbital solar power stations and lunar power systems as of early 2026. These efforts aim to harness abundant solar energy in space and provide reliable power for future Moon bases.
Orbital solar power has seen groundbreaking progress. In 2025, Japan achieved the world’s first successful wireless transmission of solar energy collected in space to Earth, paving the way for larger demonstrations. The OHISAMA satellite is scheduled for launch in 2026 to test scalable beaming technology. China continues ambitious plans for megawatt-scale stations by 2030, while the UK’s Space Solar and other projects explore robotic assembly and integration with offshore wind farms. Elon Musk and SpaceX are pushing orbital solar-powered data centers for AI, leveraging Starship’s massive payload capacity to deploy hundreds of gigawatts of solar infrastructure. Private ventures like PowerBank and Star Catcher report revenue growth and successful power-beaming tests, signaling commercial viability. The global SBSP market is projected to grow rapidly, with multiple satellite launches planned for 2026.
On the Moon, NASA and the Department of Energy are committed to deploying a fission surface power reactor by 2030, targeting 40–500 kW systems capable of operating through lunar nights. Recent milestones include powering up the Gateway station’s solar arrays and collaborations on nuclear designs that could support Artemis bases. Power-beaming demonstrations (like those from Intuitive Machines and Star Catcher) offer complementary solutions for extended lunar surface operations. These systems are critical for sustained human presence, resource utilization, and future Mars missions.
Elon Musk’s vision of interconnected space and energy continues to influence the field: Starship’s role in heavy-lift logistics could enable rapid deployment of both orbital solar arrays and lunar nuclear plants. As demonstrations turn into operational systems in the coming years, space-based energy is transitioning from concept to reality, promising limitless clean power for Earth and beyond.
Elon Musk’s vision combines space exploration with revolutionary energy solutions. Through SpaceX, he has transformed the aerospace industry by developing reusable rockets like Falcon 9 and Starship, dramatically reducing the cost of access to orbit and enabling ambitious goals such as colonizing Mars and deploying the Starlink constellation for global internet coverage. At the same time, Tesla and its energy division are reshaping the global energy landscape with electric vehicles, massive battery storage systems (Megapack), and solar products that accelerate the transition to sustainable energy. Musk sees space and clean energy as interconnected: abundant solar power in space could one day beam energy to Earth, while reliable renewable energy on Earth is essential to support large-scale spaceflight. His companies demonstrate that bold technological leaps in both domains are not only possible but already underway.
Elon Musk: “We’ll be launching with SpaceX orbital data centers at the 100 to 200 gigawatt per year level. Not cumulative; I mean per year. And ultimately, we see a path to maybe launching as much as a terawatt per year of compute from Earth. But what if you want to go beyond a mere terawatt per year? In order to do that, you have to go to the moon. By having factories on the moon, building AI satellites and having a mass driver….which is the kind of thing you really only read about in science fiction, but we’re going to make it real. We’re actually going to have a mass driver on the moon. And if you do that, you can go several orders of magnitude greater. You can go to a thousand gigawatts or more per year and ultimately get to maybe a millionth and then a thousandth and maybe even a few percent of the sun’s energy. It’s difficult to imagine what an intelligence of that scale would think about, but it’s going to be incredibly exciting”.
