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

NASA’s Interstellar Mapping and Acceleration Probe (IMAP) mission has released new data from seven of its ten science instruments, following its successful launch on September 24, 2025. The prime mission began on February 1, with all instruments collecting data. The seven instruments that have released data include the magnetometer (MAG), developed by Imperial College London, which measures the interplanetary magnetic field; the Solar Wind and Pickup Ions instrument (SWAPI), developed by Princeton University, which studies ions from the solar wind and beyond; the High-energy Ion Telescope (HIT), developed by NASA’s Goddard Space Flight Center, which analyzes high-energy ions; the Global Solar Wind Structure instrument (GLOWS), developed by the Space Research Center of the Polish Academy of Sciences, which examines the ultraviolet glow of the solar wind; the Solar Wind Electron instrument (SWE), developed by Los Alamos National Laboratory, which measures electrons in the solar wind; the Compact Dual Ion Composition Experiment instrument (CoDICE), developed by the Southwest Research Institute, which assesses the mass and electric charge of ions; and the Interstellar Dust Experiment instrument (IDEX), developed by the Laboratory for Atmospheric and Space Physics, which measures the composition of interstellar and interplanetary dust particles.

This data is available through NASA’s Space Physics Data Facility and at imap.princeton.edu/data. In addition to the released data, IMAP also provides near real-time space weather data, known as IMAP Active Link for Real-Time (I-ALiRT), which is transmitted continuously for forecasters.
