- Description
- NASA Interstellar Mapping and Acceleration Probe (IMAP) is an active heliophysics mission launched on 24 September 2025. Stationed at Sun-Earth L1, IMAP maps the heliosphere boundary, studies solar-wind and interstellar particles, and supports space-weather observations.
- Destination
- Sun–Earth L1 Lagrange Point for mapping the heliosphere boundary and measuring solar-wind and interstellar particles
- Launch Site
- Outcome
- IMAP began its primary science mission on February 1, 2026. NASA reported in August 2026 that all ten instruments were collecting data and released science measurements from seven instruments, covering magnetic fields, solar-wind particles, energetic ions, ultraviolet emission, and interstellar dust. Its I-ALiRT service also delivers frequent near-real-time measurements for space-weather forecasters.
