Overview

• In July 2025 NASA released WISPR imagery from its record-setting December 2024 flyby that brought the probe within 6.2 million kilometers of the Sun
• The images reveal multiple coronal mass ejections piling up and clarify the heliospheric current sheet’s boundary
• Detailed views of solar wind flows and magnetic structures are being integrated into forecasting tools to better predict geomagnetic storms
• Researchers say the data will enhance protection for astronauts and Earth-based technologies by pinpointing where space weather threats originate
• The probe is slated to return for its next close pass on September 15, 2025, further advancing solar corona research
