- Triple mission liftoff: SpaceX is set to launch a Falcon 9 rocket on Sept. 23, 2025 at 7:32 a.m. EDT from Launch Complex 39A at Kennedy Space Center in Florida nasa.gov. The rocket will carry three spacecraft on a rideshare journey toward the Sun – a primary NASA science probe and two smaller “space weather” observatories.
- NASA’s IMAP – mapping the Sun’s bubble: The lead payload is NASA’s Interstellar Mapping and Acceleration Probe (IMAP), tasked with mapping the boundaries of the heliosphere – the vast “bubble” created by the Sun’s solar wind that envelops our solar system science.nasa.gov science.nasa.gov. IMAP’s ten instruments will collect particles and energetic neutral atoms flying in from the heliosphere’s edge to chart this invisible frontier, improving our understanding of how the Sun’s activity shapes and protects life on Earth science.nasa.gov science.nasa.gov.
- NOAA’s SWFO-L1 – a solar storm sentinel: Also aboard is NOAA’s Space Weather Follow-On L1 (SWFO-L1) satellite, the first NOAA mission dedicated entirely to operational space weather monitoring. From its perch about 1 million miles from Earth, SWFO-L1 will continuously watch the Sun with a special coronagraph telescope and measure the solar wind in real time, acting as an early warning beacon for solar flares and coronal mass ejections nesdis.noaa.gov nesdis.noaa.gov. Its 24/7 data feed to NOAA’s Space Weather Prediction Center will give power grid operators, airlines, satellite controllers and other stakeholders critical lead time to protect infrastructure and astronauts from solar storms nesdis.noaa.gov nesdis.noaa.gov.
- Carruthers Observatory – Earth’s outer halo: The third payload is NASA’s Carruthers Geocorona Observatory, a small UV telescope named after pioneering Black scientist Dr. George Carruthers. It will capture the first continuous movies of Earth’s “geocorona” – the tenuous outermost layer of our atmosphere, which extends far into space science.nasa.gov science.nasa.gov. By imaging this faint hydrogen gas halo, Carruthers will reveal how Earth’s exosphere swells and shrinks in response to solar activity, filling a key gap in understanding how space weather affects the region astronauts traverse on the way to the Moon and Mars science.nasa.gov science.nasa.gov.
- Why it matters now: These missions arrive at a crucial time. The Sun is currently ramping up toward its next solar maximum, and NASA studies show solar activity has been unexpectedly on the rise since 2008, reversing a long quiet trend sciencesprings.wordpress.com sciencesprings.wordpress.com. More solar storms are expected in the coming years, heightening risks of geomagnetic disruption to technology on Earth. By stationing advanced monitors at Lagrange Point 1 (L1) – a gravitational balance point 1.5 million km sunward – NASA and NOAA aim to strengthen Earth’s shields. Together, IMAP, SWFO-L1, and Carruthers will give scientists and forecasters unprecedented insight into the Sun-Earth environment and early warnings up to 30 minutes before dangerous solar particles reach Earth science.nasa.gov sciencesprings.wordpress.com.
Unveiling a New “Space Weather” Mission Trio
In a single launch, SpaceX’s Falcon 9 will boost a trio of missions that promise to illuminate how the Sun influences our cosmic neighborhood – and help protect Earth from the Sun’s outbursts. NASA’s IMAP, NOAA’s SWFO-L1, and NASA’s Carruthers Geocorona Observatory will all ride into space together, bound for a point about one million miles from Earth in the direction of the Sun science.nasa.gov. There, at the Sun-Earth L1 Lagrange point, the three spacecraft can maintain a stable position and continuously face the Sun, an ideal vantage to monitor solar emissions and their impact on the space around Earth science.nasa.gov. This launch (targeted for Sept. 23, 2025) marks one of the most multifaceted science missions yet on a single Falcon 9, combining pure research with operational forecasting to guard our planet nasa.gov sciencesprings.wordpress.com.
Space weather refers to the variable conditions on the Sun and in the space environment that can impact Earth and human technologies. Sudden eruptions like solar flares or coronal mass ejections can hurl intense radiation and charged particles toward Earth, potentially knocking out satellites, disrupting communications and navigation, damaging power grids, and endangering astronauts outside Earth’s protective magnetic field sciencesprings.wordpress.com nesdis.noaa.gov. “Space weather is one of the largest threats to modern society and yet the least known,” NOAA officials note, cautioning that an extreme solar storm (like the 1859 Carrington Event) today could cause trillions of dollars in damage and take years to recover from nesdis.noaa.gov nesdis.noaa.gov. That looming threat is driving these new missions. Each will tackle a different piece of the Sun-Earth puzzle: IMAP will investigate the solar wind’s boundary with interstellar space, SWFO-L1 will serve as an operational solar storm sentinel, and Carruthers will probe how Earth’s own atmosphere responds at the fringes of space.
NASA’s IMAP: Mapping the Sun’s Invisible Shield
Interstellar Mapping and Acceleration Probe (IMAP) is NASA’s newest heliophysics mission, and the primary payload of this launch. IMAP’s goal is ambitious: to chart the very edge of the heliosphere, the giant protective bubble inflated by the Sun’s constant outflow of plasma called the solar wind science.nasa.gov science.nasa.gov. The heliosphere stretches far beyond Pluto, where the solar wind finally slows down and meets the interstellar medium. Understanding this boundary is critical – it’s essentially Earth’s cosmic force field, shielding us from many high-energy cosmic rays and interstellar radiation. Yet much about the heliosphere’s shape, structure, and dynamics remains unknown. “Studying the heliosphere helps scientists understand our home in space and how it came to be habitable,” NASA explains science.nasa.gov.
IMAP will build on the legacy of past missions that probed the heliosphere. The Voyager 1 and 2 spacecraft in 2012 and 2018 became humanity’s first emissaries to cross the heliosphere’s edge (the heliopause), sending back tantalizing data from interstellar space science.nasa.gov. And since 2009, NASA’s IBEX (Interstellar Boundary Explorer) has been imaging the heliosphere from Earth’s vicinity by detecting energetic neutral atoms, or ENAs. But IBEX’s maps were low-resolution and raised new questions, like the mysterious “ribbon” of energy it saw encircling the heliosphere. IMAP is designed to take the next leap: it carries ten instruments and will survey the heliospheric boundary with 30 times higher resolution and much faster imaging than IBEX science.nasa.gov. Essentially, IMAP is a modern celestial cartographer set to draw the first detailed all-sky map of our Sun’s protective bubble science.nasa.gov science.nasa.gov.
How will it do this? Energetic neutral atoms (ENAs) are key. These are particles that start out as charged ions from the Sun but become neutral when they interact with interstellar gas, then zip back toward Earth in straight lines science.nasa.gov. By catching ENAs arriving from all directions, IMAP can work backwards to figure out where they came from – effectively “imaging” distant regions billions of miles away that would otherwise be invisible science.nasa.gov. Three of IMAP’s instruments are dedicated to ENA detection, making it a powerful ENA observatory science.nasa.gov. “With its comprehensive state-of-the-art suite of instruments, IMAP will advance our understanding of two fundamental questions: how particles are energized and transported throughout the heliosphere, and how the heliosphere itself interacts with our galaxy,” said Dr. Shri Kanekal, IMAP mission scientist science.nasa.gov. In other words, IMAP will help reveal how solar wind particles get sped up to high energies and what happens at that clash between solar and galactic space.
Beyond mapping the heliosphere’s edge, IMAP has a second crucial role: monitoring solar wind and space radiation in real time. Stationed at L1, IMAP will constantly sample the stream of solar particles headed toward Earth. NASA says IMAP will provide around 30 minutes of warning for “dangerous particles” like solar energetic particles from a flare, buying time for satellite operators or astronauts to take shelter science.nasa.gov. This near-real-time data will feed into improved predictive models of space weather events “ranging from power-line disruptions to loss of satellites,” which is especially important as humanity plans for deep space travel science.nasa.gov. “The IMAP mission will provide very important information for deep space travel, where astronauts will be directly exposed to the dangers of the solar wind,” noted Dr. David McComas, IMAP’s principal investigator at Princeton science.nasa.gov. With NASA’s Artemis program aiming to send astronauts to the Moon and eventually Mars, having IMAP’s early warnings and heliospheric insights will be a boon for keeping crews safe from radiation beyond Earth’s magnetic cocoon sciencesprings.wordpress.com.
IMAP is led by an international team headed by Dr. McComas and managed by the Applied Physics Laboratory, and it represents the fifth mission in NASA’s Solar Terrestrial Probes program of heliophysics research science.nasa.gov. In summary, IMAP will deepen scientific knowledge of our solar system’s boundary while also acting as a space weather sentry bridging the gap between the Sun and Earth. As Dr. Patrick Koehn, IMAP program scientist at NASA, put it, “With IMAP, we’ll push forward the boundaries of knowledge of our place not only in the solar system, but our place in the galaxy as a whole.” Ultimately, “missions like IMAP will add new pieces of the space weather puzzle that fills the space between Parker Solar Probe at the Sun and the Voyagers beyond the heliopause” science.nasa.gov – linking close-up studies of the Sun to measurements out in interstellar space.
NOAA’s SWFO-L1: Guarding Earth from Solar Storms
Riding shotgun with IMAP is a very practical spacecraft: NOAA’s Space Weather Follow-On Lagrange-1 (SWFO-L1). If IMAP is about discovery, SWFO-L1 is about defense – it’s essentially a space weather early warning satellite for the nation. The SWFO-L1 observatory will occupy the same general L1 point as IMAP, continuously staring at the Sun and measuring the solar wind in order to detect solar eruptions headed our way. The need for SWFO-L1 is pressing: our current space weather monitoring relies on aging satellites that have far outlived their design lives. NASA and NOAA’s old observatories like ACE (launched 1997) and DSCOVR (launched 2015) sit at L1 today, and even NASA/ESA’s venerable SOHO (launched 1995) watches the Sun from a different vantage. These workhorses have provided critical data for decades, but they could fail at any time. In fact, NOAA warned back in 2020 that “due to current space weather missions greatly exceeding their life expectancy, there is a growing likelihood of a continuity gap in space weather data in the near future. Any gap will severely limit NOAA’s forecasting capability for space weather events”, said Dr. Elsayed Talaat of NOAA nesdis.noaa.gov. SWFO-L1 is designed to prevent that gap, ensuring we don’t go “blind” to incoming solar storms.
According to NOAA, SWFO-L1 “will maintain observational continuity of real-time solar imagery and solar-wind measurements and replace the two legacy missions – DSCOVR and SOHO” nesdis.noaa.gov. In essence, it’s the next-generation space weather sentinel. The spacecraft carries a Compact Coronagraph (built by the U.S. Naval Research Lab) to take images of the Sun’s corona and detect coronal mass ejections (CMEs) as they blast off the Sun nesdis.noaa.gov. This instrument will allow forecasters to spot an Earth-directed solar storm roughly at the same time it leaves the Sun. Meanwhile, SWFO-L1’s in-situ sensors – including a solar wind plasma sensor, a magnetometer, and a high-energy particle detector developed by U.S. research institutions nesdis.noaa.gov – will sample the stream of solar wind in real time. By being stationed at L1 (about 1% of the way from Earth to the Sun), SWFO-L1 can register the solar wind’s speed, density, and magnetic field about 60 minutes before that solar wind reaches Earth. For faster, more dangerous particle bursts, it can give on the order of 15–30 minutes warning science.nasa.gov. That may not sound like much, but for power grid operators or satellite controllers, every minute counts to safely power down systems or switch satellites into safe mode. Even commercial airlines can reroute high-latitude flights to avoid communication blackouts with a bit of warning.
All data from SWFO-L1 will be streamed live to NOAA’s Space Weather Prediction Center (SWPC), which is the “National Weather Service” for space weather. This enables forecasters to issue alerts, watches and warnings to industry and the public. The 24/7 coverage of solar conditions will help “protect the nation’s power grid, communication and navigation systems, and support the safety of astronauts and space-based infrastructure”, NOAA notes nesdis.noaa.gov. Sectors vulnerable to space weather – energy, telecommunications, aviation, GPS, military operations and more – depend on these alerts to take preventive action nesdis.noaa.gov nesdis.noaa.gov. For example, power companies can temporarily reconfigure the grid to avoid overload, and satellite operators can delay launches or maneuvers. With Solar Cycle 25 expected to peak around 2025–2026, SWFO-L1’s arrival is well-timed to bolster our resilience during what could be the Sun’s most active period in decades sciencesprings.wordpress.com sciencesprings.wordpress.com.
Technologically, SWFO-L1 represents a collaboration of American industry and research. The satellite bus and assembly were provided by BAE Systems in Colorado, and various instruments come from partners like NASA, NRL, University of California–Berkeley, University of New Hampshire, and Southwest Research Institute nesdis.noaa.gov. At around 1,500 pounds, SWFO-L1 is a fairly small satellite that can take advantage of being a secondary “rideshare” payload. Notably, NOAA coordinated closely with NASA to ensure SWFO-L1 “does no harm” to IMAP – meaning its presence won’t interfere with the primary mission’s requirements nesdis.noaa.gov nesdis.noaa.gov. This includes everything from not vibrating too much during launch to not electromagnetically disturbing IMAP’s sensors. By piggybacking on a NASA science launch, NOAA also saves significant costs. Once in space, SWFO-L1 will cruise to the L1 point over about 3–4 months and settle into a halo orbit around L1. NOAA expects the satellite to arrive by January 2026 and complete commissioning by March 2026, after which it will become fully operational nesdis.noaa.gov nesdis.noaa.gov.
In summary, SWFO-L1 is Earth’s new solar storm watchdog. It continues a line of L1 sentinels (like ACE and DSCOVR) but with improved instruments and a dedicated focus. With this mission, NOAA aims to ensure we have no lapse in our ability to see what the Sun is throwing at us, safeguarding both everyday technologies and ambitious endeavors like Artemis moon missions. As the Sun’s activity intensifies, SWFO-L1 will be our “eyes on the Sun,” helping to keep the modern world safe from the Sun’s ancient temper.
Carruthers Geocorona Observatory: Revealing Earth’s Invisible Halo
The final member of this space convoy is smaller but no less intriguing: NASA’s Carruthers Geocorona Observatory. We often think of “space weather” only as things coming from the Sun toward Earth, but Earth itself has an outer atmospheric layer that reacts to solar activity in important ways. This mission is all about Earth’s exosphere – the uppermost fringe of our atmosphere where molecules escape into space. The exosphere is so thin and tenuous that it’s practically a vacuum, merging imperceptibly with outer space. Yet during solar storms, this region can heat up and change, which in turn can affect satellites in low Earth orbit and the trajectories of spacecraft leaving Earth. Carruthers will for the first time continuously monitor this elusive region by imaging the geocorona – a huge, faint cloud of hydrogen atoms surrounding Earth that glows in ultraviolet (UV) light science.nasa.gov science.nasa.gov.
The telescope is named after the late Dr. George Carruthers, a trailblazing Black astrophysicist who in the 1960s and 70s developed the first instruments to observe the geocorona. In fact, Carruthers built a far-UV camera that flew to the Moon on Apollo 16 in 1972, which astronauts deployed on the lunar surface science.nasa.gov science.nasa.gov. From the Moon, his camera captured the first-ever images of Earth’s geocorona – revealing a ghostly ultraviolet glow extending far beyond Earth. Those Apollo-era images astonished scientists. “The camera wasn’t far enough away, being at the Moon, to get the entire field of view,” said Dr. Lara Waldrop, principal investigator for the Carruthers Observatory. “And that was really shocking – that this light, fluffy cloud of hydrogen around the Earth could extend that far from the surface.” science.nasa.gov In other words, the geocorona was bigger than the Moon’s orbit. Later studies have suggested Earth’s exosphere might extend at least halfway to the Moon in distance science.nasa.gov. But since Apollo 16, we’ve not had dedicated instruments to study it—until now.
The Carruthers Geocorona Observatory is a small satellite (about 531 pounds, the size of a sofa) that will use two specialized UV cameras to watch Earth’s atmospheric halo from afar science.nasa.gov science.nasa.gov. One is a “near-field” imager to zoom in on regions close to Earth, and the other is a “wide-field” imager to see the full span of the geocorona in one view science.nasa.gov. By combining these views, scientists can for the first time create movies of how hydrogen atoms are distributed around Earth and how this distribution changes during different conditions science.nasa.gov science.nasa.gov. When a burst of solar wind hits Earth, for example, how does the exosphere respond? Does it swell like a balloon, or get distorted? These are not just academic questions. The exosphere is the first part of Earth’s environment that solar radiation encounters, so it can serve as an early indicator of incoming disturbances science.nasa.gov. Additionally, hydrogen escaping from Earth through the exosphere is tied to the question of how our planet retains water. (Hydrogen is one component of water, H₂O, so hydrogen loss to space over eons could clue scientists into why Earth kept its oceans while, say, Mars lost much of its water.) science.nasa.gov Mapping that process has implications for identifying other planets that might hold onto water. “Understanding the exosphere’s response is important to predicting and mitigating the effects of [space weather] storms,” NASA explains, and it can also “shed light on why Earth retains water while other planets don’t” science.nasa.gov.
Scientists are excited because “we’ve never had a mission before dedicated to making exospheric observations,” said Dr. Alex Glocer, Carruthers mission scientist at NASA Goddard. “It’s really exciting that we’re going to get these measurements for the first time.” science.nasa.gov The data will fill a gap in our understanding of near-Earth space. By studying Earth’s exosphere in detail, we also gain a template for how atmospheres escape from planets in general. Earth is the only planet we know of with life, and its atmosphere is a key part of that. “Understanding how that works at Earth will greatly inform our understanding of exoplanets and how quickly their atmospheres can escape,” noted Dr. Waldrop science.nasa.gov. In other words, by watching Earth’s outer atmosphere leak away, we might better recognize which distant planets could hold onto theirs (and possibly sustain life).
Carruthers’ journey is tightly linked with IMAP’s. After all three spacecraft launch together, they will separate in space and each perform a months-long cruise to reach the L1 point. About four months after launch, Carruthers will settle into an orbit around L1, positioning itself roughly four times farther from Earth than the Moon – finally far enough out to capture the whole geocorona in one frame science.nasa.gov science.nasa.gov. After about a month of checkouts, the observatory will begin its science phase around March 2026, and operate for at least two years science.nasa.gov. The mission is led by Dr. Lara Waldrop at University of Illinois, with UC Berkeley’s Space Sciences Lab managing the payload development in collaboration with Utah State University, and the spacecraft bus provided by BAE Systems science.nasa.gov. Fittingly, Dr. George Carruthers – the man who first revealed Earth’s halo – was an alumnus of University of Illinois, making this mission a heartfelt continuation of his legacy science.nasa.gov. If all goes well, the Carruthers Observatory will give us a stunning new perspective on our planet’s “invisible halo,” even as IMAP and SWFO-L1 scrutinize the Sun itself.
Launch and Destination: The Road to L1
Sending three spacecraft to the Sun-Earth L1 point is a logistical challenge that showcases NASA’s partnership with commercial launch provider SpaceX. Falcon 9’s role is to dispatch the payloads on a trajectory toward L1, which lies about 1.5 million kilometers (932,000 miles) from Earth toward the Sun. This is far beyond the orbit of the Moon (which is ~384,000 km away), but nowhere near as distant as, say, Mars at its closest. L1 is a gravitational balance point where the pull of Earth and Sun equate the centripetal force needed for a spacecraft to move with Earth’s orbit. As a result, objects placed near L1 can hold position relative to Earth with minimal fuel, making it a prized spot for solar observers. An artist’s concept shows L1 among the five Sun-Earth Lagrange points, each a potential parking spot for spacecraft science.nasa.gov. L1 in particular “affords an uninterrupted view of the Sun” and will be home to three new heliophysics missions in 2025: IMAP, Carruthers, and SWFO-L1 science.nasa.gov. They will likely join a couple of older satellites still at L1 (like DSCOVR) until those retire.
The Falcon 9 is expected to deploy the spacecraft in a sequence – IMAP as the primary payload, and the two secondary satellites after that. All three will then use their onboard propulsion to gradually cruise out to L1. This transfer journey will take on the order of 4 months, after which each will enter a halo orbit around L1 (a looping orbit that keeps them near the balance point) science.nasa.gov. In the meantime, ground controllers will check out the spacecraft systems. NASA’s Launch Services Program, based at Kennedy Space Center, arranged this launch and had to ensure the Falcon 9 meets the requirements of all three missions beaumontenterprise.com nesdis.noaa.gov. One interesting aspect is the “rideshare” arrangement: NOAA’s SWFO-L1 had to be designed to not impact the primary mission, IMAP, in any way. This meant strict limits on things like electromagnetic interference and even scheduling (SWFO-L1 had to be ready on NASA’s timeline) nesdis.noaa.gov nesdis.noaa.gov. That coordination appears to have paid off – both NOAA and NASA officials have expressed confidence in the partnership and seamless integration.
For SpaceX, this mission is a bit different from the typical Starlink launches that have dominated its schedule. Launching science probes to L1 requires precise orbital insertion and might use a rare expendable upper stage burn to reach the high-energy transfer orbit (L1 orbits often require launching to an escape trajectory, somewhat like going toward interplanetary space). However, Falcon 9 has successfully launched similar missions to L1 before (for instance, DSCOVR in 2015). The booster for this mission is expected to land back on Earth or a drone ship after boosting the payload beyond low-Earth orbit, though those details depend on fuel margins and are typically confirmed closer to launch. What’s clear is that SpaceX’s affordable, reliable launch services have enabled missions like IMAP and SWFO that might otherwise have waited for a rideshare opportunity. In fact, this is the 9th NASA science mission to fly on a Falcon 9 under the Launch Services Program, reflecting how commonplace Elon Musk’s workhorse rocket has become for government missions beaumontenterprise.com.
As the countdown ticks down on September 23rd, excitement will be high. The launch is not only sending up cutting-edge science instruments, but also the hopes of researchers eager to see the Sun-Earth system in a new light. Media coverage is planned, and NASA will stream the liftoff and pre-launch briefings on NASA TV and online platforms nasa.gov. Should weather or technical issues arise, backup launch windows in late September are likely available, since orbital mechanics allow daily opportunities for L1 transfers. Once launched, all three spacecraft will unfurl their solar panels, point them sunward for power, and begin the long cruise. By early 2026, we’ll have a new constellation of sentinels on station at L1, just in time for the peak of the solar cycle.
A New Era of Sun-Earth Awareness
This multifaceted mission underscores a new era in which understanding and coping with the Sun’s influence is more important than ever. Humanity’s reliance on technology – and our ambitions to explore beyond Earth – mean we can’t afford to ignore space weather. With IMAP, SWFO-L1, and the Carruthers Observatory, we are essentially fortifying our neighborhood: mapping the borders of the Sun’s domain, getting advance notice of solar tempests, and learning how Earth’s own atmospheric fringes behave. It’s a holistic approach to heliophysics that bridges fundamental science and practical forecasting.
Experts liken this mission to adding missing puzzle pieces. IMAP fills in knowledge between NASA’s sun-skimming Parker Solar Probe (which is currently diving through the Sun’s corona) and the distant Voyager probes in interstellar space science.nasa.gov. SWFO-L1 extends the legacy of solar sentinels into the future, ensuring continuous vigilance as the Sun’s activity rises. Carruthers brings a long-awaited focus to our immediate cosmic backyard – the edge of Earth’s environment itself – which will inform everything from protecting astronauts in transit to understanding atmospheric escape on other worlds.
Crucially, these missions are coming online just as the Sun “wakes up” from a relative slumber. According to a new NASA analysis, after a decades-long lull, solar activity began increasing after 2008 and is now on an upward trend sciencesprings.wordpress.com sciencesprings.wordpress.com. More sunspots, flares, and CMEs are expected as we approach Solar Maximum around 2025–2026. “All signs were pointing to the Sun going into a prolonged phase of low activity… so it was a surprise to see that trend reversed. The Sun is slowly waking up,” said Dr. Jamie Jasinski, lead author of that study sciencesprings.wordpress.com. The timing of IMAP, SWFO-L1, and Carruthers could not be better. Their data will feed into research and models that help predict solar storms, and by extension, help decision-makers mitigate their impact on Earth’s infrastructure and explorers in deep space sciencesprings.wordpress.com sciencesprings.wordpress.com.
In the big picture, the Sun-Earth connection is a fundamental piece of what makes Earth habitable. By probing the heliosphere’s boundary, IMAP will tell us how our solar system interacts with the galaxy and filter out harmful cosmic rays science.nasa.gov science.nasa.gov. By tracking the Sun’s eruptions, SWFO-L1 will protect the systems that modern life depends on and give us more confidence as we venture outward nesdis.noaa.gov nesdis.noaa.gov. By examining Earth’s exosphere, Carruthers will deepen our understanding of our own planet’s response to the Sun and aid the search for life on exoplanets science.nasa.gov science.nasa.gov. It’s a comprehensive assault on the unknowns of our space environment.
NASA’s Heliophysics Division has emphasized the collaborative nature of this effort – not just between NASA and NOAA, but also academia, industry, and international partners. A total of 27 institutions are involved in IMAP alone science.nasa.gov. This points to a trend of doing more with partnerships and shared launches, maximizing science per dollar. The IMAP launch also carries some NASA technology experiments and student-built CubeSats (which often hitchhike on such missions) – though those were not the focus here, they add even more value to the flight.
Ultimately, when Falcon 9’s engines ignite and lift these spacecraft toward the dawn sky, it will symbolize humanity taking yet another stride in demystifying the Sun’s influence on our lives. As Patrick Koehn at NASA said, it’s about “pushing forward the boundaries of knowledge… of our place in the galaxy as a whole” science.nasa.gov. Armed with the new eye of IMAP, the watchful gaze of SWFO-L1, and the keen insight of Carruthers, we will be better prepared than ever before to live in the atmosphere of an active star. The Sun may be waking up, but with these missions, so are we.
