The Parker Solar Probe uses a specialized carbon-composite foam shield to survive temperatures up to 2,500 degrees Fahrenheit. This thermal protection system allows the spacecraft to maintain room temperature for its instruments while skimming the Sun's corona. This engineering feat highlights the effectiveness of carbon-carbon composites and foam structures in managing extreme thermal gradients. The material is 97 percent air by volume, demonstrating how advanced carbon materials can be used for high-performance insulation in the most hostile environments known to man.
