UK Space Solar and UKAEA Collaborate on Groundbreaking Robotic Infrastructure Project in Orbit
Robotic Innovations: Paving the Way for Space Infrastructure
Date: 29 May 2025
In a groundbreaking collaboration that could redefine our approach to space and energy, the United Kingdom Atomic Energy Authority (UKAEA) has teamed up with innovative firm Space Solar. Their joint project, "AlbaTRUSS," aims to demonstrate how robotic technology can be utilized to construct critical infrastructure in space, including data centers and solar energy farms—all without human intervention.
Pioneering the AlbaTRUSS Project
Conducted at UKAEA’s state-of-the-art facilities on the Culham Campus in Oxfordshire, the AlbaTRUSS project utilized remotely operated dual-arm robotic manipulators. This successful demonstration showed that robots could assemble gigawatt-scale solar power satellites, marking a significant milestone not only for satellite architecture but also for the future of large-scale structures in orbit.
Dr. Sam Adlen, Co-CEO of Space Solar, emphasized the project’s importance: “The AlbaTRUSS project is a milestone not just for our satellite architecture but for the future of large-scale structures in space, from data centers to energy infrastructure.”
A Vision for Space-Based Solar Power
Space Solar’s vision goes beyond mere experimentation; they aim to harness the abundant solar energy available in space to power energy-hungry consumers on Earth. The concept involves complex satellites made up of hundreds of thousands of modular units that need to be constructed in orbit. “Up in space, the sun shines 24/7,” explained Dr. Adlen. “Once constructed, these satellites capture solar power and beam it back down to Earth in the form of microwaves, which can be received by antennas on the ground and converted into electricity for the grid.”
These structures are designed to be several kilometers long and approximately 20 meters wide, functioning as vital energy hubs in space.
Efficiency and Safety in Space Construction
One of the most significant advantages of using robotic technology in space is efficiency. Traditional methods involve human astronauts, which inherently come with risks and limitations. Robots can assemble, maintain, and even decommission infrastructure remotely, helping to mitigate dangers faced by crewed missions.
UKAEA utilized its Centre for Remote Applications in Challenging Environments (RACE) for the AlbaTRUSS project, as both fusion and space robotics function in harsh, oxygen-poor environments and can operate under varying levels of radiation.
Professor Rob Buckingham, Executive Director of UKAEA, remarked on the synergy between fusion energy and space construction, indicating the parallel complexities involved: “Building a machine as complicated as a fusion power plant on Earth, which will be entirely remotely operated, is similar to building structures in space.”
The Bigger Picture: Energy Security and Innovation
Both space-based solar power and fusion energy present promising pathways to deliver consistent, low-carbon baseload energy globally. The partnership between UKAEA and Space Solar underscores the UK’s ambitions to lead in the rapidly growing In-Space Assembly and Manufacturing (ISAM) sector.
As Dr. Adlen noted: “This achievement opens up new horizons for the space sector, an adjacent economic sphere that can ensure a bright future here on Earth.”
Supported by the Science and Technology Facilities Council’s Proof of Concept grant, Space Solar has its sights set on commissioning a 30MW demonstrator system by 2029, aiming to achieve full gigawatt-scale capacity by the early 2030s.
Conclusion
The AlbaTRUSS project marks a transformative moment in our understanding of what is possible in space-based infrastructure. As the collaboration between UKAEA and Space Solar advances, we are not only approaching new frontiers in energy solutions but also ensuring a sustainable future for generations to come. The potential for robotic technology in space is limitless—and the journey has only just begun.
