NASA's Parker Solar Probe successfully completed a close approach to the Sun, confirming normal system operations. Reaching speeds of 687,000 km/h, it matched its previous velocity record. The probe's fourth flyby collected crucial data on solar wind and flares, vital for understanding space weather and protecting Earth-based infrastructure and future space missions.NASA's Parker Solar Probe successfully completed a close approach to the Sun, confirming normal system operations.
