In a groundbreaking mission, NASA's Parker Solar Probe is on track to achieve a remarkable feat by flying closer to the sun than any previous spacecraft. Launched in 2018, the probe has already ventured through the sun's corona, the outer atmosphere visible during a total solar eclipse.
The next significant milestone for the Parker Solar Probe is its closest approach to the sun, scheduled for Tuesday. The spacecraft is expected to pass within a record-breaking distance of 3.8 million miles (6 million kilometers) from the sun's surface, which is equivalent to being on the 4-yard line of a football field if the sun and Earth were at opposite ends.
