IMAP & others on Falcon 9 Block 5. Wed 24 Sept 2025, 11:30:50 UTC. Reported outcome: Success. Launch site: Launch Complex 39A. Source: Launch Library 2.
IMAP (Interstellar Mapping and Acceleration Probe) is a NASA mission to study interactions between solar wind and the local interstellar medium. Carrying a suite of 10 scientific instruments, IMAP is able to investigate how particles are accelerated, determine their composition, as well as help to advance space weather forecasting models. The IMAP launch also includes the space weather satellite SWFO-L1 (Space Weather Follow-On - L1) for NOAA and the GLIDE (Global Lyman-alpha Imagers of the Dynamic Exosphere/Carruthers Geocorona Observatory) mission to study far ultraviolet emission in the Earth's exosphere.
