Orbital Data Centres: Why reality might not match the hype

The Kármán Line

Show Notes

What are orbital data centres (ODCs) and how do they differ from orbital edge computing? How do they solve the bottleneck of transmitting massive volumes of data from space to Earth? How believable is the central premise of the SpaceX IPO, that because space offers unlimited real estate, solar energy and natural radiative cooling it is therefore the future of Earth’s AI computing needs? Why are some experts sceptical and is there a danger that while AI demand is real, the infrastructure market could be a bubble waiting to happen? And why is developing sovereign ODC capabilities so “critical”?

Join Alice and Jason Aspiotis, CEO and co-founder for a European space startup, as they talk about the “net present value” and future potential of ODCs, the lack of a “conviction to pursue something big” in Europe, and the terrifying or intriguing prospect of neuromorphic computing chips that mimic the low-power, high efficiency processing of the human brain.

How does winning the UK Space Agency's Active Debris Removal (UK ADR) contract position ClearSpace to capture defunct satellites? How do their multi-arm robotics and advanced machine-learning algorithms match up to the task? How does active debris removal establish a long-term national capability and commercial service layer in space? And what does a transition from R&D grants to major anchor contracts mean for hyper-scaling UK In-Orbit Servicing, Assembly, and Manufacturing (ISAM)?

How does Metalysis strip oxygen as a captured gas from metal oxides and convert the oxide into pure metal alloys? How will this help us to supply life support for lunar bases or create rocket propellant for deep-space refuelling? Once the oxygen is stripped away how can the remaining metal alloys be repurposed for 3D-printed infrastructure, landing pads or road surfaces? And how can Metalysis’ research help regolith inks to print electronic components directly in space?

How can ultra-lightweight "black box" sensors turn a spacecraft's surface into an impact detector to diagnose anomalies? What do satellite operators need to unlock affordable, named-peril collision insurance through Lloyd's of London? And how can a "neighbourhood watch" network of sensor-equipped satellites build live space domain awareness to protect the space economy?

How is space transitioning from a niche frontier to an everyday commercial workplace? What role do regulatory frameworks, such as the United Nations, the Artemis Accords, and the Astra Carta, play in keeping orbit and the lunar surface safe and sustainable? And how can the UK Government act as an "anchor customer" to bridge the commercial "valley of death" for domestic space startups?
