| Oh I have done the math. There are multiple ways to get cooling to work in space: 1. There is no real size limit to radiators in space, especially when in solar orbit. 2. High temperature chip architectures can be used, operating at 600K. 3. Heat pipes can bring the temperature even higher, such as to 1200K. 4. Special 3D radiator geometries can be used to optimize heat escape. 5. Metamaterials can be used to optimize photon emission in the best directions. Together, these will shrink the required radiator area dramatically. Beyond these standard ideas, other exotic approaches exist at the edge of viability. The ISS in contrast is restricted considering it has to sit in Earth orbit.
