NASA sent its Parker Solar Probe just 3.8 million miles from the surface of the Sun — and it survived. The probe transmitted a signal back to Earth on the night of December 26th, “indicating it’s in good health and operating normally,” according to NASA.

According to NASA, the Parker Solar Probe reached speeds of up to 430,000 miles per hour, enduring temperatures as high as 1,800 degrees Fahrenheit (982 Celsius). Although the probe is scheduled to orbit the sun two more times, this mission marks the closest it will ever get.

It’s designed to take solar punishment like never before, thanks to its revolutionary heat shield that’s capable of withstanding 2,500 degrees Fahrenheit (1,370 degrees Celsius).
