Ablative Heat Shields

  1. Dec 6, 2005 #1
    I know that the heat shields on space capsules today are ablative, but what are they made of? :confused: Any help would be welcome.

    In the new X-33 the substance Iconel 617 is used in the honeycomb TPS (thermal protection system). Generally, Nextel (a ceramic) is used.
