These photos and timelapse show NASA’s IMAP mission being loaded into the thermal vacuum chamber of NASA Marshall Space Flight Center’s X-Ray and Cryogenic Facility (XRCF) in Huntsville, Alabama. IMAP arrived at Marshall March 18 and was loaded into the chamber March 19. IMAP will undergo testing such as dramatic temperature changes to simulate the harsh environment of space. The XRCF’s vacuum chamber is is 20 feet in diameter and 60 feet long making it one of the largest across NASA. The IMAP mission is a modern-day celestial cartographer that will map the solar system by studying the heliosphere, a giant bubble created by the Sun’s solar wind that surrounds our solar system and protects it from harmful interstellar radiation.

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.

Launch is targeted for no earlier than September 2025 aboard a SpaceX Falcon 9 rocket from Launch Complex 39A at NASA Kennedy.

Technicians test the spring-activated door on the Interstellar Dust Experiment (IDEX) 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 Tuesday, June 3, 2025. The door will remain closed to protect IDEX from contamination during integration and launch. Once in space, the door will swing open permanently to allow interstellar and interplanetary dust to flow into the instrument for measurement. The IMAP observatory will study how the Sun shapes the boundaries of the heliosphere, the protective bubble around our solar system.

The National Oceanic and Atmospheric Administration’s (NOAA) Space Weather Follow On–Lagrange 1 (SWFO-L1) Observatory, set to provide quicker and more accurate space weather forecasts, arrived Sunday, July 20, 2025, at the Astrotech Space Operations Facility near NASA’s Kennedy Space Center in Florida. The SWFO-L1 mission will monitor the Sun and near-Earth environment using a suite of instruments that provide real-time measurements of solar activity. The observatory will launch as a rideshare with NASA’s IMAP (Interstellar Mapping and Acceleration Probe) no earlier than September 2025.

Technicians inspect a motorized light band for NASA’s Carruthers Geocorona Observatory on Tuesday, July 22, 2025, at the Astrotech Space Operations Facility near the agency’s Kennedy Space Center in Florida. The Carruthers Geocorona Observatory is a small satellite set to operate at Lagrange Point 1 (L1), an orbit point between the Earth and Sun about one million miles away. Carruthers will use its ultraviolet cameras to monitor how space weather from the Sun impacts the exosphere, the outermost part of Earth’s atmosphere. The observatory will launch as a rideshare with NASA’s IMAP (Interstellar Mapping and Acceleration Probe) no earlier than September 2025.
