Rolls Royce building nuclear reactor to enable humans to live on the Moon

All space missions depend on a power source, to support systems for communications, life-support and science experiments

Rolls-Royce is building a nuclear reactor let humans live on the Moon.

The UK Space Agency will help fund work on the technology, intended to allow the lunar surface to be more habitable.

The project will examine how nuclear power can be used to support human life on the Moon.

Scientists and engineers at the British company are working on the Micro-Reactor programme to develop technology that will provide power needed for humans to live and work on Earth’s natural satellite.

All space missions depend on a power source, to support systems for communications, life-support and science experiments.

Experts suggest nuclear power could potentially dramatically increase the length of lunar missions.

The UK Space Agency has announced £2.9 million of new funding for the project, which will deliver an initial demonstration of a UK lunar modular nuclear reactor.

Space exploration is the ultimate laboratory for so many of the transformational technologies we need on Earth: from materials to robotics, nutrition, cleantech and much more

This comes after a £249,000 study funded by the UK Space Agency in 2022.

Science minister George Freeman said: “Space exploration is the ultimate laboratory for so many of the transformational technologies we need on Earth: from materials to robotics, nutrition, cleantech and much more.

“As we prepare to see humans return to the Moon for the first time in more than 50 years, we are backing exciting research like this lunar modular reactor with Rolls-Royce to pioneer new power sources for a lunar base.

“Partnerships like this, between British industry, the UK Space Agency and government are helping to create jobs across our £16 billion Space Tech sector and help ensure the UK continues to be a major force in frontier science.”

Rolls-Royce plans to have a reactor ready to send to the Moon by 2029.

It will work with a variety of collaborators including the University of Oxford, University of Bangor, University of Brighton, University of Sheffield’s Advanced Manufacturing Research Centre (AMRC) and Nuclear AMRC.

This funding will bring us further down the road in making the Micro-Reactor a reality, with the technology bringing immense benefits for both space and Earth

Compared to other power systems, a relatively small and lightweight nuclear micro-reactor could enable continuous power regardless of location, available sunlight, and other environmental conditions.

Abi Clayton, director of future programmes for Rolls-Royce said: “This funding will bring us further down the road in making the Micro-Reactor a reality, with the technology bringing immense benefits for both space and Earth.

“The technology will deliver the capability to support commercial and defence use cases alongside providing a solution to decarbonise industry and provide clean, safe and reliable energy.”

Dr Paul Bate, chief executive of the UK Space Agency, said: “This innovative research by Rolls-Royce could lay the groundwork for powering continuous human presence on the Moon, while enhancing the wider UK space sector, creating jobs and generating further investment.”
