IMAP Instrument Reintegration for SWAPI - Mechanical Installatio

Technicians reintegrate the Solar Wind and Pickup Ions (SWAPI) instrument of NASA’s IMAP (Interstellar Mapping and Acceleration Probe) observatory inside the high bay at the Astrotech Space Operations Facility near the agency’s Kennedy Space Center in Florida on Monday, June 23, 2025. As IMAP spins in space, solar wind particles are swept into SWAPI through a special opening called “sunglasses,” an opening covered by a screen with very tiny precise holes that cut down the brightness of the very intense solar wind. SWAPI collects and counts particles from the solar wind flowing from the Sun and particles called pick-up ions that have entered the heliosphere from outside the solar system and traveled inwards where IMAP orbits near Earth. Launch of the IMAP mission is targeted for no earlier than September 2025 aboard a SpaceX Falcon 9 rocket from Launch Complex 39A at NASA Kennedy.
