NASA’s IMAP Mission Releases New Data From 7 Science Instruments

Science data from NASA's IMAP (Interstellar Mapping and Acceleration Probe) mission is now available. After its successful launch on Sept. 24, 2025, IMAP's prime mission began a few months later, on Feb. 1.

All 10 instruments on IMAP have been successfully collecting data. While data from three of the instruments are not yet ready for release, science data collected through April 30 by seven instruments can be accessed from NASA's Space Physics Data Facility and imap.princeton.edu/data.

Data is available from the following instruments:

• MAG - The magnetometer, developed by Imperial College London, measures the interplanetary magnetic field originating from the Sun.
• SWAPI - The Solar Wind and Pickup Ions instrument, developed by Princeton University in New Jersey, measures ions from the solar wind, a constant stream of charged particles from the Sun, and particles from beyond the solar system.
• HIT - The High-energy Ion Telescope, developed by NASA's Goddard Space Flight Center in Greenbelt, Maryland, studies high-energy ions originating from solar wind and deep space.
• GLOWS - The Global Solar Wind Structure instrument, developed by the Space Research Center of the Polish Academy of Sciences, studies the ultraviolet glow produced by the solar wind to better understand how it evolves over time.
• SWE - The Solar Wind Electron instrument, developed by Los Alamos National Laboratory in New Mexico, measures electrons found in the solar wind.
• CoDICE - The Compact Dual Ion Composition Experiment instrument, developed by the Southwest Research Institute in San Antonio, Texas, measures the mass and electric charge of ions originating from both interstellar space and the solar wind.
• IDEX - The Interstellar Dust Experiment instrument, developed by the Laboratory for Atmospheric and Space Physics in Boulder, Colorado, measures the composition of interstellar and interplanetary dust particles.

Also available is IMAP Active Link for Real-Time (I-ALiRT) data, near real-time space weather data which continues to be transmitted at a high cadence rate, 24 hours a day, 7 days a week for forecasters.
