The Interstellar Mapping and Acceleration Probe (IMAP) is a NASA mission set to launch in 2025, aimed at studying the boundary of the heliosphere—the protective bubble formed by the solar wind that surrounds our solar system—and its interaction with the interstellar medium. Positioned at the Sun-Earth Lagrange Point 1 (L1), IMAP will use ten advanced instruments to map this boundary by detecting energetic neutral atoms (ENAs) and other particles created at the heliosphere’s edge. The mission seeks to deepen understanding of how particles are accelerated in space and how the Sun influences space weather and the interstellar environment. IMAP’s findings will help unravel fundamental questions about the solar system’s place in the galaxy and enhance predictions of space weather effects on Earth.
