A NASA spacecraft, Parker Solar Probe, is set to make history by flying closer to the sun than any object before it. Launched in 2018, the probe has already flown through the sun’s corona, its outer atmosphere visible during a total solar eclipse. On Tuesday, Parker will pass within a record-breaking 3.8 million miles of the sun’s surface, making it the closest human-made object to reach the sun.
