NASA's  Parker Solar Probe is the robotic spacecraft to probe the outer  corona of the sun. The cutting-edge heat shield called the Thermal Protection System  has been installed on  Parker  Solar Probe scheduled for August launch. The heat shield will help the spacecraft remain safe  as it collects data about the inner workings of the corona. The heat shield is made of two panels of superheated  carbon composite sandwiching a lightweight  4.5 inch thick carbon foam core.
