Why did Parker not burn despite experiencing such high temperatures? A four-and-a-half-inch-thick carbon composite shield surrounds Parker. It is shield resistant to temperatures up to 1377 C.
But isn’t the atmosphere of the sun really hot?
That’s right. There is great heat in the corona of the sun. But the density there is low. Due to this, the heat transfer particles are less.
That’s what saves Parker. Parker will not get much hotter from there because the particles are smaller. The sum is only 1377 degrees.
