| | | | | Welcome to the latest edition of our Space Solar newsletter, where we bring you updates on our progress and the dynamic developments in the space energy sector. It has been an exciting quarter for Space Solar, completing a design study that shows pathways to power cheaper than terrestrial solar; developing our in-space assembly robotics with interest from a range of customers for large space infrastructure; and adding some stellar capabilities to our brilliant team. The Space Solar journey is accelerating with momentum growing quickly around space-based solar power, large space infrastructure and wireless power transmission. |
| | CASSiDi completed. Next: Commercial SBSP |
| | | We’re proud to announce the successful completion of CASSiDi - an ambitious 18-month, £1.7 million project aimed at advancing the design maturity of our pioneering CASSIOPeiA satellite. Delivered in collaboration with 22 leading engineering organisations, CASSiDi marks a significant milestone in the development of space-based solar power (SBSP), demonstrating a step-change in clean energy generation and building real momentum toward commercial deployment by 2030. |
|
| | | AlbaTRUSS delivers major leap for SBSP |
| | | Building on our assembly concept, we’re pleased to announce the successful completion of AlbaTRUSS, our proof-of-concept project demonstrating the viability of autonomous in-space assembly for solar power satellites. Delivered in partnership with UKAEA’s RACE robotics division and supported by the STFC Cross Cluster Proof of Concept grant, this project provides crucial validation of our modular robotic assembly architecture. It marks a key step in de-risking the path to scalable, gigawatt-level space-based solar power - a future trillion-dollar energy opportunity. |

| | | | | | In a new RE:TV film, Sam Adlen joins global energy leaders to spotlight bold innovation - and why space-based solar will be the climate breakthrough we’ve been waiting for. Our tech? 24/7 clean power, scalable to 15GW by the 2040s. |
| | | | The spotlight at CERAWeek 2025 |
| At CERAWeek 2025, space-based solar power took the spotlight as global energy leaders tackled the future of energy security, grid resilience, and innovation. Our Co-CEO, Sam Adlen, joined the conversation with a powerful session on ‘Powering our future wirelessly from space’. |
| | | Farnborough was a standout moment - we showcased our HARRIER wireless power beaming demonstrator and connected with leaders across defence, industry, and government.
Sam Adlen took the stage to share why space-based solar is key to the future space economy. |
| |
| | Space Solar at Satellite 2025 |
| At Satellite 2025, Martin Soltau shared why SBSP is ready to be financed and deployed like any other energy infrastructure.
Key takeaways? Finance is flowing, collaboration is crucial, and the time to lead in space energy is now.

| | Space Solar celebrates Future Fifty launch |
|
| | | This week Space Solar was honoured to stand alongside the UK’s most innovative companies at 10 Downing Street, celebrating the launch of the Tech Nation Future Fifty 2025 cohort. Our co-CEO Martin Soltau met with the Prime Minister to share how this technology can help deliver the government’s priorities for economic growth and energy security. Independent studies confirm that just 8 GW of space-based solar power in the UK’s energy mix will deliver net savings of £4.1 Bn per annum. We’re proud to bring the mission of space-based solar power to the table – proving that affordable, reliable, baseload energy for everyone, everywhere is within reach. Events like this show what’s possible when innovators, investors, and policymakers come together to back transformative technologies. |
