The NASA Parker Solar Probe spacecraft, built by the Johns Hopkins University Applied Physics Lab will fly through the outermost part of the Sun s atmosphere taking in situ measurements and imaging to improve our understanding of the corona and the solar wind. The Thermal Protection System (TPS), a 4.5-inch thick carbon-composite heat shield, limits heat transfer to the spacecraft during its flight through the Sun s atmosphere, and casts a shadow which protects the spacecraft and its instruments from the harsh thermal enviro ...

Solar Probe Plus (SPP) is a NASA mission that will go within ten Solar Radii of the sun. One of the crucial technologies in this system is the Thermal Protection System (TPS), which shields the spacecraft from the sun. The TPS is made up of carbon-foam sandwiched between two carbon-carbon panels, and is approximately eight feet in diameter and 4.5 inches thick. At its closest approach, the front surface of the TPS is expected to reach 1200°C, but the foam will dissipate the heat so the back surface will only be about 300 ...

The Solar Probe Plus (SPP) spacecraft is equipped with four thermal radiators as part of the solar array cooling system. This cooling system rejects the heat absorbed by two high heat flux solar arrays. Each thermal radiator is comprised of nine aluminum radiation fins that are bonded with epoxy to titanium tubes. These tubes are connected together via inlet and outlet manifolds to create each radiator assembly. The solar arrays are cooled by micro-channel-etched titanium plates through which the working fluid, water, is for ...
