Space suits utilize specialized thermal insulation and water sublimator or evaporator systems to manage and regulate internal temperature in harsh environments.
The claim specifically asserts that space suits regulate internal temperature in extreme environments using thermal insulation and water sublimators. Paper [4] discusses advanced space suit insulation for extreme temperature environments, and Paper [5] covers spacesuit waste heat rejection using water membrane evaporators and references NASA sublimator systems. Both aspects of the claim are directly supported.
