Parker Solar Probe's Heat Shield Enters Thermal Vacuum Testing

To protect NASA’s Parker Solar Probe from the intense heat of the Sun’s atmosphere, scientists and engineers developed a revolutionary Thermal Protection System, or TPS. This heat shield, made of carbon-carbon composite material, will experience temperatures of almost 2,500 degrees Fahrenheit (1,370 Celsius) as the spacecraft hurtles through the solar atmosphere, while keeping the instruments
