On August 12, 2018, NASA launched the Parker Solar Probe to study the Sun like never before. It's hurtling toward the star at the center of our solar system at 120 miles per second, making it the fastest human-made object ever. The heat shield on the front of the probe will withstand temperatures of about 2500 degrees Fahrenheit to keep the instruments at roughly room temperature. The probe will study solar wind, coronal mass ejections, and why the Sun’s atmosphere is unexpectedly hotter than its surface.
