A comment on A superconducting shield for astronauts.

I wonder how much cooling superconductors need in space.

Basically, how warm is the interior of a satellite with a high albedo (gold foil?) in the inner solar system?

Thermal management in space is a big issue. The ISS has big radiators on the long truss, and lots of plumbing for cooling.

For a superconducting magnetic shield, it depends how much power is used to maintain it. MgB2 supports high currents compared to cuprates, so I guess once it's turned on it doesn't need much?
