IMAP Sunset at LC 39A

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 atop stands vertical at Launch Complex 39A as the sun sets on Monday, Sept. 22, 2025, at the agency’s Kennedy Space Center in Florida. The missions will each focus on different effects of the solar wind — the continuous stream of particles emitted by the Sun — and space weather — the changing conditions in space driven by the Sun — from their origins at the Sun to their farthest reaches billions of miles away at the edge of our solar system.
