David McComas, IMAP principal investigator, Princeton University, participates in a science briefing on NASA’s IMAP (Interstellar Mapping and Acceleration Probe) 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 – at the agency’s Kennedy Space Center in Florida on Sunday, Sept. 21, 2025. 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. The three missions will orbit the Sun near Lagrange point 1, about one million miles from Earth. Launch is targeted for 7:32 a.m. EDT, Tuesday, Sept. 23, from Launch Complex 39A at NASA Kennedy.
