Description: In this episode, we dive into NASA’s IMAP mission—the Interstellar Mapping and Acceleration Probe—set to study the heliosphere, the magnetic bubble that shields our solar system.Led in part by University of Delaware scientist William H. Matthaeus, IMAP will orbit at Lagrange Point 1 to analyze solar wind, plasma, and magnetic fields. Joined by the Carruthers Geocorona Observatory and NOAA’s Space Weather Follow On, this mission will expand our view of how the sun interacts with interstellar space.
