Rules of the road needed for orbital data center constellations

Industry and government experts convened at a Secure World Foundation panel to address safety protocols for emerging orbital data center constellations. With proposals ranging from tens of thousands to one million satellites, officials emphasized the urgent need for coordinated "rules of the road" in low Earth orbit. Ezra Feilden of Starcloud suggested adapting SpaceX’s Starlink best practices, noting that while Starlink operates safely with 10,000 satellites, larger constellations face exponentially higher collision risks. Feilden argued that satellites in non-intersecting dawn-dusk orbits could mitigate this, provided they all travel in the same direction. Without such coordination, head-on collisions become a severe threat. Jeff O’Neil of Planet compared proposed space traffic systems to global air traffic control. Meanwhile, the Office of Space Commerce is developing a voluntary certification system. Officials urged operators to adopt best practices immediately rather than waiting for regulatory mandates to ensure safe coexistence among massive satellite networks.

💡 The proposed scale of these constellations transforms low Earth orbit from a sparse environment into a dense traffic zone, making standardized directional protocols essential to prevent catastrophic collisions. Without immediate industry consensus on orbital "lanes," the risk of debris-generating accidents threatens to render critical space infrastructure unusable.

EU launches €30B push to build 7 massive AI data centers

The European Union officially launched a funding process for seven massive AI data centers, aiming to bolster Europe’s competitiveness in artificial intelligence. This initiative fulfills a commitment by European Commission President Ursula von der Leyen to help the region catch up in the global AI race. The plan involves supporting four smaller hubs, each equipped with 25,000 to 75,000 specialized AI chips, and three larger facilities powered by 40,000 to 100,000 chips. Winning bids will be selected by early next year, with an 18-month construction timeline. Public funding could reach €1 billion for smaller projects and €2 billion for larger ones, capped at 35 percent of total investment. Combined with private capital, the total investment is projected to hit €30 billion. The Commission has earmarked €1 billion initially, with a potential additional €4 billion from the next long-term budget, though this remains uncertain due to ongoing negotiations. This public-private partnership represents a significant step in securing European compute power.

💡 The strict 35 percent cap on public subsidies forces private investors to shoulder the majority of the financial risk, testing the viability of European AI infrastructure without excessive state aid. This structure determines whether Europe can sustainably compete with US and Chinese tech giants or if the project will stall due to funding gaps.

How silicon photonics lights the way for data centers

Global data center spending is projected to reach $7 trillion by 2030, driven by the massive capital and architectural investments required to scale artificial intelligence. Modern infrastructure struggles to support simultaneous cloud computing and AI surges, creating significant operational bottlenecks. Rising AI adoption increases demand for GPU density and bandwidth, which accelerates model training but generates excessive heat. Current electron-based data transmission is resource-intensive, consuming vast amounts of electricity, water, and rare materials. Consequently, the operational runway for existing data centers is shortening. Silicon photonics emerges as a critical solution, combining light with electrons to enable faster, more energy-efficient data transmission. Although photonics research spans over four decades, with integration potential identified in the 1980s, widespread adoption has been delayed. This technology addresses the limitations of traditional electronic systems, offering a pathway to scale GPU clusters and AI data centers effectively while mitigating cooling challenges and resource consumption associated with current computational methods.

💡 Silicon photonics directly tackles the physical limits of electron-based computing, offering a viable path to sustain AI growth without exhausting global energy and water resources.
