Parker Solar Probe Completes Closest Solar Flyby

The Parker Solar Probe achieved its closest-ever solar flyby in December 2024, passing within 6.1 million kilometers of the Sun's surface at a record-breaking speed of 690,000 km/h, making it the fastest human-made object ever. Data published throughout 2025 unveiled new mechanisms behind solar wind acceleration and corona physics, directly improving space weather predictions. With a rate of insight generation that outperforms #10's commercial goals, this mission provides concrete protections for satellites and power grids against solar storms. Its velocity is 30% lighter than the typical rival in terms of drag, ensuring unprecedented proximity.
