Scheduled for launch in September 2025, the Interstellar Mapping and Acceleration Probe (IMAP) is a NASA heliophysics mission that will explore the heliopause from its final orbital location at the L-1 Lagrange point. One component of the IMAP mission is the IMAP Active Link for Real-Time (I-ALiRT) data stream that provides approximately 2400 bits of heliophysics data per second. Similar to the real time space weather data provided by DSCOVR (Deep Space Climate Observatory) and ACE (Advanced Composition Explorer), I-ALiRT will provide a new data set for the space weather prediction community that includes the magnetic field, electron fluxes, thermal plasmas, solar wind charge state ratios, suprathemal ions, and relativistic proton measurements.

I-ALiRT data will be available to the space weather community within five minutes of receipt at the IMAP Science Data Center (SDC) at the Laboratory for Atmospheric and Space Physics. The SDC is developing a set of tools to enable the community to access the data for use in prediction models or monitoring operations. Critical to the full functionality of the I-ALiRT system is a worldwide network of antenna partners, which are currently being assembled and being used to test data delivery and processing.
