then again further cooling 20 °C in a vacuum and complete darkness might also be feasible

  You could maybe have a liquid nitrogen hose bonded to the tape, circulating to a refrigeration unit on the rim.

  Vacuum is not a good conductor of heat, unfortunately. Air would be.

    I mean, the James Webb makes use of such to drop to, what, 20 Kelvin? https://ttu-ir.tdl.org/bitstream/handle/2346/67554/ICES_2016_141.v2.pdf?sequence=1 https://ttu-ir.tdl.org/bitstream/handle/2346/67554/ICES_2016...

    Still the thing you manage to cool down (via radiation in the end, of course) will stay cold as it won't pick up more heat from the environment so easily in vacuum.

  It is possible a mirrored tent over it would keep enough glare from sunshine on the rim off, allowing it to cool further.
