Early on Christmas Eve in 2024, a NASA craft swooped at blazing speed through the sun's atmosphere.
The Parker Solar Probe, equipped with a robust heat shield, made the closest-ever approach to our dynamic star, coming some 3.8 million miles (6.1 million kilometers) from the stellar surface. That's seven times closer than any other probe. The mission is designed to fly into the sun's corona, or outer atmosphere, which spawns many of the powerful solar storms and weather that impact Earth.
