6 Min Read Upcoming Launch to Boost NASA’s Study of Sun’s Influence Across Space
Soon, there will be three new ways to study the Sun’s influence across the solar system with the launch of a trio of NASA and National Oceanic and Atmospheric Administration (NOAA) spacecraft. Expected to launch no earlier than Tuesday, Sept. 23, 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 three missions will launch together aboard a SpaceX Falcon 9 rocket from NASA’s Kennedy Space Center in Florida. From there, the spacecraft will travel together to their destination at the first Earth-Sun Lagrange point (L1), around one million miles from Earth toward the Sun.
The missions will each focus on 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 and observations 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 and airline crews from space weather impacts.
The IMAP and Carruthers missions add to NASA’s heliophysics fleet of spacecraft. Together, NASA’s heliophysics missions study a vast, interconnected system from the Sun to the space surrounding Earth and other planets to the farthest limits of the Sun’s constantly flowing streams of solar wind. The SWFO-L1 mission, funded and operated by NOAA, will be the agency’s first satellite designed specifically for and fully dedicated to continuous, operational space weather observations.
Mapping our home in space: IMAP
The IMAP mission will study the heliosphere, our home in space.
NASA/Princeton University/Patrick McPike As a modern-day celestial cartographer, IMAP will investigate two of the most important overarching issues in heliophysics: the interaction of the solar wind at its boundary with interstellar space and the energization of charged particles from the Sun.
The IMAP mission will principally study the boundary of our heliosphere — a huge bubble created by the solar wind that encapsulates our solar system — and study how the heliosphere interacts with the local galactic neighborhood beyond. The heliosphere protects the solar system from dangerous high-energy particles called galactic cosmic rays. Mapping the heliosphere’s boundaries helps scientists understand our home in space and how it came to be habitable.
“IMAP will revolutionize our understanding of the outer heliosphere,” said David McComas, IMAP mission principal investigator at Princeton University in New Jersey. “It will give us a very fine picture of what’s going on out there by making measurements that are 30 times more sensitive and at higher resolution than ever before.”
The IMAP mission will also explore and chart the vast range of particles in interplanetary space. The spacecraft will provide near real-time observations of the solar wind and energetic particles, which can produce hazardous conditions not only in the space environment near Earth, but also on the ground. The mission’s data will help model and improve prediction capabilities of the impacts of space weather ranging from power-line disruptions to loss of satellites.
Imaging Earth’s exosphere: Carruthers Geocorona Observatory
An illustration shows the Carruthers Geocorona Observatory spacecraft. NASA/BAE Systems Space & Mission Systems The Carruthers Geocorona Observatory, a small satellite, will launch with IMAP as a rideshare. The mission was named after Dr. George Carruthers, creator of the Moon-based telescope that captured the first images of Earth’s exosphere, the outermost layer of our planet’s atmosphere.
The Carruthers mission will build upon Dr. Carruthers’ legacy by charting changes in Earth’s exosphere. The mission’s vantage point at L1 offers a complete view of the exosphere not visible from the Moon’s relatively close distance to Earth. From there, it will address fundamental questions about the nature of the region, such as its shape, size, density, and how it changes over time.
The exosphere plays an important role in Earth’s response to space weather, which can impact our technology, from satellites in orbit to communications signals in the upper atmosphere or power lines on the ground. During space weather storms, the exosphere mediates the energy absorption and release throughout the near-Earth space environment, influencing strength of space weather disturbances. Carruthers will help us better understand the fundamental physics of our exosphere and improve our ability to predict the impacts of the Sun’s activity.
“We’ll be able to create movies of how this atmospheric layer responds when a solar storm hits, and watch it change with the seasons over time,” said Lara Waldrop, the principal investigator for the Carruthers Geocorona Observatory at the University of Illinois at Urbana-Champaign.
New space weather station: SWFO-L1
SWFO-L1 will provide real-time observations of the Sun’s corona and solar wind to help forecast the resulting space weather.
NOAA/BAE Systems Space & Mission Systems Distinct from NASA’s research satellites, SWFO-L1 will be an operational satellite, designed to observe solar activity and the solar wind in real time to provide critical data in NOAA’s mission to protect the nation from environmental hazards. SWFO-L1 will serve as an early-warning beacon for potentially damaging space weather events that could impact our technology on Earth. SWFO-L1 will observe the Sun’s outer atmosphere for large eruptions, called coronal mass ejections, and measure the solar wind upstream from Earth with a state-of-the-art suite of instruments and processing system.
This mission is the first of a new generation of NOAA space weather observatories dedicated to 24/7 operations, working to avoid gaps in continuity.
“SWFO-L1 will be an amazing deep-space mission for NOAA,” said Dimitrios Vassiliadis, SWFO program scientist at NOAA. “Thanks to its advantageous location at L1, it will continuously monitor the solar atmosphere while measuring the solar wind and its interplanetary magnetic fields well before it impacts Earth — and transmit these data in record time.”
With SWFO-L1’s enhanced performance, unobstructed views, and minimal delay between observations and data return, NOAA’s Space Weather Prediction Center forecasters will give operators improved lead time required to take precautionary actions that protect vital infrastructure, economic interests, and national security on Earth and in space.

Webb captured this sparkling scene of star birth in Pismis 24. Full image and caption below. Credits:
Image: NASA, ESA, CSA, STScI; Image Processing: A. Pagan (STScI) This is a sparkling scene of star birth captured by NASA’s James Webb Space Telescope. What appears to be a craggy, starlit mountaintop kissed by wispy clouds is actually a cosmic dust-scape being eaten away by the blistering winds and radiation of nearby, massive, infant stars.
Called Pismis 24, this young star cluster resides in the core of the nearby Lobster Nebula, approximately 5,500 light-years from Earth in the constellation Scorpius. Home to a vibrant stellar nursery and one of the closest sites of massive star birth, Pismis 24 provides rare insight into large and massive stars. Its proximity makes this region one of the best places to explore the properties of hot young stars and how they evolve.
At the heart of this glittering cluster is the brilliant Pismis 24-1. It is at the center of a clump of stars above the jagged orange peaks, and the tallest spire is pointing directly toward it. Pismis 24-1 appears as a gigantic single star, and it was once thought to be the most massive known star. Scientists have since learned that it is composed of at least two stars, though they cannot be resolved in this image. At 74 and 66 solar masses, respectively, the two known stars are still among the most massive and luminous stars ever seen.

Webb captured this sparkling scene of star birth in Pismis 24, a young star cluster about 5,500 light-years from Earth in the constellation Scorpius. This region is one of the best places to explore the properties of hot young stars and how they evolve. Image: NASA, ESA, CSA, STScI; Image Processing: A. Pagan (STScI) Captured in infrared light by Webb’s NIRCam (Near-Infrared Camera), this image reveals thousands of jewel-like stars of varying sizes and colors. The largest and most brilliant ones with the six-point diffraction spikes are the most massive stars in the cluster. Hundreds to thousands of smaller members of the cluster appear as white, yellow, and red, depending on their stellar type and the amount of dust enshrouding them. Webb also shows us tens of thousands of stars behind the cluster that are part of the Milky Way galaxy.
Super-hot, infant stars –some almost 8 times the temperature of the Sun – blast out scorching radiation and punishing winds that are sculpting a cavity into the wall of the star-forming nebula. That nebula extends far beyond NIRCam’s field of view. Only small portions of it are visible at the bottom and top right of the image. Streamers of hot, ionized gas flow off the ridges of the nebula, and wispy veils of gas and dust, illuminated by starlight, float around its towering peaks.
Dramatic spires jut from the glowing wall of gas, resisting the relentless radiation and winds. They are like fingers pointing toward the hot, young stars that have sculpted them. The fierce forces shaping and compressing these spires cause new stars to form within them. The tallest spire spans about 5.4 light-years from its tip to the bottom of the image. More than 200 of our solar systems out to Neptune’s orbit could fit into the width its tip, which is 0.14 lightyears.
In this image, the color cyan indicates hot or ionized hydrogen gas being heated up by the massive young stars. Dust molecules similar to smoke here on Earth are represented in orange. Red signifies cooler, denser molecular hydrogen. The darker the red, the denser the gas. Black denotes the densest gas, which is not emitting light. The wispy white features are dust and gas that are scattering starlight.
