IMAP Encapsulation

Technicians at Astrotech Space Operations Facility near NASA’s Kennedy Space Center in Florida encapsulate NASA’s IMAP (Interstellar Mapping and Acceleration Probe) spacecraft on Tuesday, Sept. 16, 2025, inside SpaceX’s Falcon 9 payload fairings to protect the spacecraft during launch. 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. This mission and its two rideshares – NASA’s exosphere-studying Carruthers Geocorona Observatory and National Oceanic and Atmospheric Administration’s (NOAA) Space Weather Follow On–Lagrange 1 (SWFO-L1) observatory – will orbit the Sun near Lagrange point 1, about one million miles from Earth, where it will scan the heliosphere, analyze the composition of charged particles, and investigate how those particles move through the solar system. Launch is targeted for no earlier than Tuesday, Sept. 23, 2025, from Launch Complex 39A at NASA Kennedy.
