IMAP

IMAP (for Interstellar Mapping and Acceleration Probe) is a future NASA mission to study the solar wind and its interaction with the surrounding interstellar medium. Among its features is continuous reporting of some real-time data useful regarding space weather. IMAP will be located at Earth-Sun Lagrangian point L1. The aim is to launch in 2025. Instruments:

• IMAP-Lo
• IMAP-Hi
• IMAP-Ultra

These are three sensors for energetic neutral atoms for three energy levels: they will sense from away from the ecliptic, and based on energy will be assumed to come from the heliosheath or beyond, where particles from the Sun interact with the ISM. Additional particle detectors:

• SWE - Solar Wind Electron (sensor).
• SWAPI - Solar Wind and Pick-up Ion (sensor).
• CoDICE - Compact Dual Ion Composition Experiment.
• HIT - High-energy Ion Telescope.

Other instruments:

• MAG - Magnetometer.
• IDEX - Interstellar Dust Experiment.
• GLOWS - Global Solar Wind Structure: will image the solar wind from scattered hydrogen and helium spectral lines.
