Sophia Space launched a modular approach to orbital computing with its TILEs, 1 m-by-1 m server tiles designed to host processors with integrated solar panels and passive heat spreaders. The startup, backed by a $10 million seed round from investors including Alpha Funds and KDDI Green Partners Fund, plans ground demonstrations before flying a satellite bus from Apex Space in late 2027 or early 2028.
The TILEs adopt a thin, sail-like form factor derived from Caltech research into orbital solar plants and integrate power generation with compute hardware to route roughly 92% of generated energy to processing. Sophia partnered with Nvidia on compatibility and is building software to manage thermal loads and distribute workloads across tiles.
For operators, TILEs aim to reduce reliance on heavy radiators and lower the cost of doing compute in orbit by enabling on-board processing of massive sensor datasets. The approach aligns with rising demand for edge space compute in earth observation, defense tracking, and advanced communications where reducing data downlinks matters.
