Space-based compute: hype, physics and the UK opportunity

Grid connections for new data centres are now measured in years. Launch costs have collapsed. As a result, compute is heading for orbit. GPUs are already running AI workloads up there, and the first commercial data centre nodes launched in January.

Some of that is real today. Some is a decade out. Some may never work. After all, rejecting waste heat in a vacuum is far harder than the pitch decks admit.

This afternoon tells the three apart and asks what all this means for the UK. The UK won't out-launch the US or out-fabricate Taiwan. But it holds real ground in onboard processing, optical links, ground segment, in-space manufacturing and the insurance market that underwrites global space risk. Which two or three of those should we actually defend, and who pays?

You'll leave with an understanding of: 

• What compute is currently in orbit, and what it costs

• Who the first buyers really are (hint: not commercial cloud)

• A shortlist of UK bets worth backing

This techUK event is being run in collaboration with HPE, a techUK member company that has been running computers in orbit for many years.
Please note: Delegate details will be shared with the host organisation HPE.

Insights from this session will form part of techUK's year-long focus series on Frontier Compute and feed into a report – to be published in early 2027 – that summarises the initiative's main findings and recommendations for key decision-makers in government.

Call for contributions: Frontier Compute insights 

 techUK is seeking insights (articles) to be published as part of our brand-new Frontier Compute focus.

Members and stakeholders can contribute insights outlining how the UK can lead on the development and deployment of Frontier Compute technologies – including Quantum, Photonic, Neuromorphic and Biological compute – and showcasing how their organisation is turning this vision into reality.

 Submissions will be promoted throughout 2026 and across the UK technology sector via techUK's website, newsletters, and social channels. Find out more here.
