| In modern vehicles, passive cooling can be found as [[reinforced carbon–carbon]] material instead of metal. This material constitutes the thermal protection system of the nose and the front edges of the Space Shuttle and was proposed for the vehicle [[Lockheed Martin X-33|X-33]]. [[Carbon]] is the most refractory material known with a sublimation temperature (for [[graphite]]) of 3825 °C. These characteristics make it a material particularly suitable for [[passive cooling]], but with the disadvantage of being very expensive and fragile. Some spacecraft also use a heat shield (in the conventional automotive sense) to protect fuel tanks and equipment from the heat produced by a large [[rocket engine]]. Such shields were used on the Apollo [[Apollo Command/Service Module#Service Module (SM)|Service Module]] and [[Apollo Lunar Module|Lunar Module]] descent stage.[[File:Gemini heat shield.jpg|thumb|Example of Ablative Heat Shield used for Gemini Missions]] | In modern vehicles, passive cooling can be found as [[reinforced carbon–carbon]] material instead of metal.
