NASA’s Parker Solar Probe is set to achieve a landmark moment by flying into the sun’s outer atmosphere, known as the corona, in an unprecedented mission on Tuesday. This event marks the closest any human-made object has ever come to a star, enabling scientists to gather data from uncharted territory. The probe will be approximately 3.8 million miles from the sun’s surface, reaching speeds of 690,000 kilometers per hour. A temporary communication blackout is expected as the spacecraft approaches, with signals anticipated to resume on Friday.
