"Why won’t the spacecraft melt?” is a perfectly reasonable question to ask about this morning's launch to "touch" the Sun. We installed a cutting-edge heat shield made of carbon-composite that will keep our #ParkerSolarProbe spacecraft and its instruments at a relatively comfortable temperature of about 85 degrees Fahrenheit. See for yourself as our engineers take a blowtorch to the shield material 🔥🔥🔥: | NASA - National Aeronautics and Space Administration
