Key Takeaways 1. Thermal management is the defining engineering bottleneck for orbital compute at every scale. 2. Space is cold, but it does not cool things, and the physics of heat rejection in vacuum are fundamentally different from anything used in terrestrial data centers. 3. At megawatt scale, radiator mass
