NASA Prepares Trio of Spacecraft for Landmark September Launch

All three spacecraft are undergoing final preparations at Astrotech Space Operations in Titusville, Florida — a Lockheed Martin subsidiary that has become one of the nation’s premier spacecraft processing hubs. The facility recently offered media a rare look inside its cleanrooms, where missions for NASA, the Department of Defense, and commercial providers are routinely assembled and readied for launch.

IMAP: Charting the Heliosphere

Leading the launch is NASA’s IMAP mission, managed by Principal Investigator David McComas of Princeton University and built by the Johns Hopkins University Applied Physics Laboratory. IMAP follows in the footsteps of the 2008 IBEX mission, using next-generation instruments to provide sharper, higher-resolution insights into the heliosphere — the bubble-like region created by the solar wind that shields Earth from cosmic radiation.

The spacecraft will work in tandem with IBEX, ensuring overlapping datasets that give scientists a multi-year view of the heliosphere’s structure. IMAP will downlink data three times a week through NASA’s Deep Space Network, offering global researchers open access to solar wind observations crucial for protecting satellites, GPS, power grids, and agriculture.

Carruthers: Imaging Earth’s Ghostly Halo

The Carruthers Geocorona Observatory, led by Lara Waldrop of the University of Illinois Urbana-Champaign, will capture unprecedented images of Earth’s outermost atmosphere — the exosphere, a faint hydrogen-rich layer nearly a million miles away.

Named for Dr. George Carruthers, who developed the ultraviolet camera flown on Apollo 16, the observatory will study how Earth retains its water, providing critical comparisons with Mars and offering insights into planetary habitability. The mission is also expected to inform preparations for future lunar and Martian exploration.

SWFO-L1: NOAA’s First Dedicated Space Weather Mission

For NOAA, the launch marks a historic milestone. SWFO-L1 will be the agency’s first spacecraft devoted entirely to space weather forecasting, stationed at the Sun-Earth Lagrange Point 1, roughly a million miles from Earth.

Unlike past sensors that shared rides on weather or research satellites, SWFO-L1 will deliver rapid, dedicated monitoring of solar activity. Data from coronal mass ejections could reach forecasters within 15 minutes, while solar wind readings may be available in as little as five minutes. These near-real-time updates will enhance warnings for power grid operators, aviation, GPS users, and even precision farming.

“NASA’s job is to do basic research and discover new things,” said Richard Ullman, deputy director for NOAA’s Office of Space Weather Observations. “Our job is to take that understanding and apply it to protecting our nation against environmental threats.”

Before reaching the launch pad at Cape Canaveral, spacecraft undergo fueling, checkout, and cleanroom integration at Astrotech. NASA recently renewed its partnership with the company through a multi-year processing contract, ensuring continued support for high-profile science missions like IMAP.

Global Collaboration and the Road Ahead

The missions underscore international teamwork. IMAP unites more than 25 institutions across six countries, including Poland’s Academy of Sciences, which is providing its first spaceflight payload, the GLOWS ultraviolet instrument. Meanwhile, NOAA’s SWFO-L1 will share its space weather data with partners in Japan, South Korea, and Europe.

The launch is currently targeted for September 23. Once deployed, IMAP will begin mapping the heliosphere, Carruthers will deliver the first wide-field images of Earth’s exosphere, and SWFO-L1 will provide real-time space weather monitoring.

Together, the three missions represent a bold leap forward — from fundamental heliophysics research to applied forecasting — highlighting NASA’s scientific reach and the essential role of commercial partners like Astrotech in preparing humanity’s next great journey into space.
