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.

NASA's Parker Solar Probe made history on Tuesday with a record-breaking flight around the sun, the space agency has confirmed. The spacecraft set a new benchmark early on the morning of Dec. 24, coming within 3.

The probe accelerated to 430,000 mph, faster than any spacecraft has ever flown, traveling to within 3.8 million miles of the star’s surface.
