NASA and SpaceX have changed the launch date of the IMAP spacecraft to September 2025 to give more time to prepare its flight system. The mission will explore the heliosphere to understand the Sun's protective bubble and its impact on space weather and life. Running concurrently with IMAP are two shared missions: the Carruthers Coronal Observatory and the National Oceanic and Atmospheric Administration's space weather tracker, Lagrange 1, which will study Earth's outer atmosphere and monitor solar activity, respectively. All three spacecraft will operate at Lagrangian 1 point to effectively monitor space conditions.
NASA and SpaceX have adjusted the launch date of the Interstellar Mapping and Acceleration Probe (IMAP) spacecraft to no earlier than September 2025. The revised schedule allows for more preparation and testing of IMAP's flight systems before launch.
The IMAP mission is designed to study the heliosphere, a magnetic bubble created by the sun that serves as the solar system's protective shield. By analyzing and mapping particles traveling from the edge of interstellar space toward Earth, IMAP will provide important insights into this protective boundary. The mission will also investigate the solar wind - the continuous flow of charged particles from the sun - as well as high-energy particles and cosmic rays within the heliosphere. Understanding these particles is critical because they can impact human space exploration, disrupt technological systems, and potentially have an impact on the existence of life in the universe.
In addition to IMAP, two spacecraft will be launched as shared missions:
NASA's Caluther Coronal Observatory will capture light from Earth's corona, the outer part of the atmosphere that emits ultraviolet light. Through the study, researchers can better understand the atmosphere and improve our ability to predict how solar activity affects the Earth.
The National Oceanic and Atmospheric Administration's (NOAA) space weather tracking Lagrange 1 mission will observe the Sun's outer atmosphere, or corona, and measure the constant stream of particles known as the solar wind before the Sun reaches Earth to monitor the conditions that produce space weather.
During their missions, all three spacecraft will orbit Lagrangian Point 1, one of five regions where Earth's gravity balances that of the Sun. A spacecraft operating at a Lagrangian point requires less fuel to remain in that position. Lagrange 1 is about one million miles away from the Earth and faces the sun. It is an excellent location for observing the sun and an early warning location for space weather conditions to the earth.
The IMAP mission is led by Princeton University Professor David J. McComas and supported by an international team from 25 partner institutions. The spacecraft was built and operated by the Johns Hopkins Applied Physics Laboratory in Laurel, Maryland. IMAP is the fifth mission in NASA's Solar-Terrestrial Explorer program, which is managed by the Explorers and Heliophysics Programs at NASA's Goddard Space Flight Center in Greenbelt, Maryland, within the agency's Science Mission Directorate Heliophysics Branch.
The Carruthers Geocorona Observatory, led by University of Illinois at Urbana-Champaign professor Lara Waldrop, is listed as a "mission of opportunity" in the Sun-Terrestrial Explorer Program. Meanwhile, the Lagrange 1 mission, which tracks space weather and is overseen by the National Oceanic and Atmospheric Administration (NOAA), is funded and managed to provide data operations, product development and distribution to users.
NASA's Launch Services Program at Kennedy Space Center in Florida coordinates launch services for these missions.
