Aside from launch costs, isn’t heat management one of the hardest parts about schemes like that? I’m obviously not an aerospace engineer, but I thought the vacuum breaks most heat dissipation schemes
Heat management is indeed difficult in space. You're basically limited to emitting in infrared since things like fans or phase change cooling has no medium to dump the heat to.
No convection or conduction, but you have radiation heat transfer. Not a space thermodynamicist, I wonder if it would work best crunching number in the shade of the earth and then just recharge in the sun.
