New Design For Data Center In Space, Like Beads On A String

The article discusses a novel design for space-based data centers developed by researchers at the University of Pennsylvania, addressing the scalability challenges of orbiting data centers. Unlike traditional concepts that rely on constellations of numerous independent satellites or futuristic, robot-assembled structures, this design uses long, tether-like cables composed of thousands of individual computing nodes arranged like beads on a string. These tethers, stretching kilometers into space, are stabilized passively by natural orbital forces and solar radiation pressure, eliminating the need for complex adjustments or external power for orientation. This approach leverages well-understood tether technology to enable large-scale deployment capable of delivering up to 20 megawatts of computing power. Key advantages of this tether-based system include reduced weight, power consumption, and complexity compared to prior designs, making it more feasible to scale orbital data centers to a size that could significantly reduce the energy and water demands of terrestrial data centers. Each computing node is equipped with lightweight radiators for heat dissipation and solar panels that both
