NASA Heads to the Sun
Clip: Season 45 | 1m 9s
On August 12, 2018, NASA launched the Parker Solar Probe to study the Sun like never before. It will hurtle towards the star at the center of our solar system at 120 miles per second, which is 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.
