NASA and the National Oceanic and Atmospheric Administration (NOAA) have launched three groundbreaking missions aimed at exploring the Sun's influence throughout the solar system. The launch, which took place at 7:30 a.m. EDT, was executed via a SpaceX Falcon 9 rocket from Launch Complex 39A at NASA’s Kennedy Space Center in Florida. The payload included the Interstellar Mapping and Acceleration Probe (IMAP), the Carruthers Geocorona Observatory, and NOAA’s SWFO-L1 (Space Weather Follow On-Lagrange 1) spacecraft.
“This successful launch enhances our nation's space weather readiness, providing better protection for our satellites, interplanetary missions, and astronauts against the dangers posed by space weather,” stated Sean Duffy, acting NASA Administrator. He further emphasized the significance of this insight as the U.S. prepares for future missions to the Moon and Mars, reinforcing America’s position as a leader in space exploration.
The objectives of these three missions are crucial for safeguarding both our terrestrial technology and our human and robotic explorers venturing into the cosmos. “As we prepare to return humans to the Moon and venture to Mars, NASA and NOAA are providing an invaluable interplanetary survival guide,” noted Nicola Fox, Associate Administrator for the Science Mission Directorate at NASA Headquarters. “Our scientific discoveries and technical innovations will contribute to a roadmap designed to ensure a prepared, safe, and sustainable human presence on other worlds.”
Each mission will focus on different aspects of space weather and the solar wind, which is a constant flow of particles released by the Sun, extending outward to interstellar space. “These three unique missions will enhance our understanding of the Sun and its effects on Earth,” remarked Joe Westlake, Heliophysics Division Director at NASA Headquarters. “This knowledge is imperative because the Sun's activity directly influences our daily lives, affecting everything from power grids to GPS systems.”
The IMAP mission aims to chart the boundary of the heliosphere—an area filled with solar wind that protects our solar system from harmful galactic cosmic rays, which is essential for maintaining Earth's habitability. The spacecraft will analyze solar wind particles traveling outward from the Sun, as well as energetic particles coming from beyond our solar system. “IMAP will deepen our understanding of how the space environment can impact our technologies and reveal the science of our solar neighborhood,” said David McComas, IMAP mission principal investigator from Princeton University.
The Carruthers Geocorona Observatory represents the first mission exclusively devoted to monitoring changes in the exosphere, the outermost layer of Earth's atmosphere, which significantly influences our planet's response to space weather. By investigating the geocorona, which emits ultraviolet light when sunlight interacts with it, this mission will unveil how the exosphere reacts to solar storms and seasonal changes. This mission builds upon the legacy of the initial instrument that imaged the geocorona during the Apollo 16 mission, designed by the renowned scientist Dr. George Carruthers.
NOAA’s SWFO-L1 mission is a pioneering initiative aimed at providing real-time space weather observations. Designed to operate continuously, SWFO-L1 will monitor solar activity and space conditions near Earth around the clock. “This observatory marks the beginning of a new generation of NOAA space weather facilities, ensuring uninterrupted operations. Real-time data from SWFO-L1 will provide essential information for issuing timely warnings, enabling decision-makers to take proactive measures to protect critical infrastructure, economic interests, and national security,” explained Richard Ullman, Deputy Director of the Office of Space Weather Observations at NOAA.
Following the successful launch, all three spacecraft promptly deployed from the rocket and confirmed their operational status by sending signals back to Earth. Over the next few months, they will travel to their designated location, known as Lagrange point 1 (L1), situated approximately one million miles from Earth. They are expected to arrive by January, after which their instruments will undergo checks and calibrations to initiate their vital missions of understanding space weather and enhancing protection for humanity.
The IMAP mission is led by David McComas from Princeton University, in collaboration with a global team of 27 partner institutions. The spacecraft was constructed and is operated by the Johns Hopkins Applied Physics Laboratory. The Carruthers mission is spearheaded by Lara Waldrop from the University of Illinois at Urbana-Champaign, with implementation managed by the Space Sciences Laboratory at the University of California, Berkeley. The SWFO-L1 mission is managed by NOAA in partnership with NASA Goddard and various commercial entities. Launch services for these missions were managed by NASA’s Launch Services Program at Kennedy Space Center.
