NASA's Parker Solar Probe flew closer to the sun than any human-made object ever — a stunning technological feat that scientists liken to the historic Apollo moon landing in 1969.

Hurtling around the sun at approximately 430,000 mph, the uncrewed vehicle is expected to come within 3.8 million miles of the sun.

On the heels of a NASA spacecraft's historic close flyby of the sun on Christmas Eve, scientists on Earth have one question on their minds: Did their probe survive as an epic Christmas gift, or is it a burned up lump of coal in space?
