NASA’s Interstellar Mapping and Acceleration Probe (IMAP) has begun final preparations at Kennedy Space Center for a launch no earlier than September 2025. The mission will position IMAP at Lagrange Point 1, a million miles from Earth, to study the solar wind and the edge of the heliosphere. The spacecraft, built by Johns Hopkins APL, will fly alongside two other satellites on a SpaceX Falcon 9. IMAP is part of NASA’s Solar Terrestrial Probes program and is led by Princeton University with contributions from 25 international partners.
