NASA's Parker Probe Survives Closest Brush with Sun

Parker Solar Probe, NASA's historic mission to solve the mysteries of the Sun, is alive and well after skimming by the Sun at just 15 million miles from its surface.
This is far closer than any spacecraft has ever gone. On November 5, the spacecraft made the closest approach, called perihelion. Parker Solar Probe reached a top speed of 213,200 miles per hour, setting a new record for spacecraft speed.
At this distance, the intense sunlight heated the Sun-facing side of Probe's heat shield, called the Thermal Protection System, to about 820 degrees Fahrenheit. This temperature will climb up to 2,500 Fahrenheit as the spacecraft makes closer approaches to the Sun, NASA said.
