Three new spacecraft are launching to guard our solar system from solar storms
A trio of NASA and NOAA missions is preparing for a coordinated launch to monitor the Sun's influence. From detecting early warnings of solar storms to mapping the edge of our solar neighborhood, these probes aim to protect Earth's critical technology and future astronauts.
Scheduled to launch on a SpaceX Falcon 9 rocket from Kennedy Space Center, the mission trio includes NASA's Interstellar Mapping and Acceleration Probe (IMAP), the Carruthers Geocorona Observatory, and NOAA's Space Weather Follow On-Lagrange 1 (SWFO-L1). These spacecraft will operate approximately one million miles from Earth at a specific location known as Lagrange Point 1. While the target launch date was updated to September 23 or 24, 2025, the primary scientific goal remains the study of the solar wind—the continuous stream of particles from the Sun—and its impact on our planetary environment.
Each mission serves a distinct scientific purpose. The IMAP spacecraft is designed to investigate how solar energy and particles interact with the heliosphere, the protective bubble surrounding our solar system. Meanwhile, the Carruthers Geocorona Observatory will focus on Earth's exosphere, capturing the faint ultraviolet glow of the geocorona to understand how space weather affects our planet. This mission specifically expands upon atmospheric measurements first recorded during the Apollo 16 era.
The SWFO-L1 mission represents a significant shift for NOAA, as it is the agency's first observatory dedicated entirely to continuous, operational space weather observations. By acting as an early warning beacon, SWFO-L1 aims to detect solar storms in advance. Such foresight is critical for safeguarding Earth's technological infrastructure and protecting both satellites and human explorers from the disruptive effects of cosmic radiation and changing space conditions.
