   How does the Parker Solar Probe keep its instruments at room temp, while venturing so close to the blazing Sun?

   It does so using an innovative 2.3 m heat shield, which uses space-age materials to keep the instruments at 29°C while the Sun facing heat shield heats up to 1,370°C. Most of the heavy-lifting is done by a 11.4 cm thick layer of carbon foam, typically used in the medical industry for bone replacement.
   See diagram below for some details.
