Launching September 23, 2025, from NASA’s Kennedy Space Center in Florida, the missions include NASA’s IMAP (Interstellar Mapping and Acceleration Probe), NASA’s Carruthers Geocorona Observatory, and NOAA’s SWFO-L1 (Space Weather Follow On-Lagrange 1) spacecraft.The missions will each study different effects of the solar wind — the continuous stream of particles emitted by the Sun — and space weather — the changing conditions in space driven by the Sun — from their origins at the Sun to their farthest reaches billions of miles away at the edge of our solar system. Research from the missions will help us better understand the Sun’s influence on Earth’s habitability, map our home in space, and protect satellites and voyaging astronauts from space weather threats.Watch the launch with NASA from anywhere in the world.

During this time, the heliosphere’s protective shield is strengthened by the increase in particles and magnetic fields from the Sun. As a result, fewer damaging particles from the galaxy, such as galactic cosmic rays, are able to penetrate into the heliosphere.
