A SpaceX Falcon 9 rocket, with NASA’s IMAP (Interstellar Mapping and Acceleration Probe), the agency’s Carruthers Geocorona Observatory, and National Oceanic and Atmospheric Administration’s (NOAA) Space Weather Follow On–Lagrange 1 (SWFO-L1) spacecraft attached, rolls to Launch Pad 39A on Sunday, Sept. 21, 2025, at NASA’s Kennedy Space Center in Florida. NASA’s IMAP will use 10 science instruments to study and map the heliosphere, a vast magnetic bubble surrounding the Sun protecting our solar system from radiation incoming from interstellar space. NASA’s IMAP will scan the heliosphere, analyze the composition of charged particles, and investigate how those particles move through the solar system.
