NASA is marking America’s 250th year with a bold new symbol of the nation’s relentless drive to explore.
The America 250 emblem is now on the twin solid rocket boosters of the SLS (Space Launch System) rocket for Artemis II — the powerhouse that will launch a crew of four around the Moon next year. Unveiled Tuesday, the design echoes the America 250 Commission’s Spirit of Innovation theme, honoring a country that has never stopped pushing the horizon forward.
At NASA’s Kennedy Space Center in Florida, technicians spent recent weeks carefully applying the emblem on the rocket inside the Vehicle Assembly Building — the same place where rockets for Apollo once stood. Engineers are running final tests on SLS and the Orion spacecraft as preparations intensify for Artemis II.
The roughly 10-day Artemis II journey around the Moon will mark a defining moment in this new era of American exploration — paving the way for U.S. crews to land on the lunar surface and ultimately push onward to Mars.
America’s spirit of discovery is alive, and Artemis is carrying it to the Moon and beyond.
The commander of the military unit responsible for running the Cape Canaveral spaceport in Florida expects SpaceX to begin launching Starship rockets there next year.
Launch companies with facilities near SpaceX’s Starship pads are not pleased. SpaceX’s two chief rivals, Blue Origin and United Launch Alliance, complained last year that SpaceX’s proposal of launching as many as 120 Starships per year from Florida’s Space Coast could force them to routinely clear personnel from their launch pads for safety reasons.
This isn’t the first time Blue Origin and ULA have tried to throw up roadblocks in front of SpaceX. The companies sought to prevent NASA from leasing a disused launch pad to SpaceX in 2013, but they lost the fight.
NASA has selected Plug Power, Inc., of Slingerlands, New York, and Air Products and Chemicals, Inc., of Allentown, Pennsylvania, to supply up to approximately 36,952,000 pounds of liquid hydrogen for use at facilities across the agency.
The NASA Agency-wide Supply of Liquid Hydrogen awards are firm-fixed-price requirements contracts that include multiple firm-fixed-price delivery orders critical for the agency’s centers as they use liquid hydrogen, combined with liquid oxygen, as fuel in cryogenic rocket engines, and the commodity’s unique properties support the development of aeronautics. The total value for the combined awards is about $147.2 million.
The contracts begin Monday, Dec. 1, and each consists of a two-year base period followed by three one-year option periods that, if exercised, would extend the contracts to Nov. 30, 2030.
Air Products and Chemicals Inc. will supply up to about 36.5 million pounds of liquid hydrogen to NASA’s Kennedy Space Center and Cape Canaveral Space Force Station in Florida; NASA’s Marshall Space Flight Center in Huntsville, Alabama; and NASA’s Stennis Space Center in Bay St. Louis, Mississippi, for a maximum contract value of approximately $144.4 million.
Plug Power, Inc. will deliver up to approximately 480,000 pounds of the commodity to NASA’s Glenn Research Center in Cleveland, Ohio, and at Neil A. Armstrong Test Facility in Sandusky, Ohio, for a maximum contract value of about $2.8 million.

Technicians with NASA’s Exploration Ground Systems team use a crane to lift and secure NASA’s Orion spacecraft on top of the SLS (Space Launch System) rocket in High Bay 3 of the Vehicle Assembly Building at NASA’s Kennedy Space Center in Florida on Saturday, Oct. 18, 2025, for the agency’s Artemis II mission. Set to launch in 2026, the spacecraft will carry NASA astronauts Reid Wiseman, Victor Glover, Christina Koch, and CSA (Canadian Space Agency) astronaut Jeremy Hansen on a 10-day mission around the Moon and back. Once stacked, teams will begin conducting a series of verification tests ahead of rolling out to Launch Complex 39B for the wet dress rehearsal at NASA Kennedy.

As 2026 nears, NASA continues moving forward to launching and flying Artemis II, the first crewed mission under the Artemis campaign, no later than April next year.
NASA’s Orion spacecraft, complete with its launch abort system escape tower, is now integrated with the SLS (Space Launch System) rocket in the Vehicle Assembly Building (VAB) at the agency’s Kennedy Space Center in Florida. Following Orion stacking, teams completed testing critical communications systems between SLS and Orion, and confirmed the interfaces function properly between the rocket, Orion, and the ground systems, including end-to-end testing with the Near Space Network and Deep Space Network, which aid in communications and navigation.
“NASA remains focused on getting ready to safely fly four astronauts around the Moon and back,” said acting NASA Administrator Sean Duffy. “Our mission will lay the groundwork for future missions to the lunar surface and to Mars.”
In the coming weeks, engineers and the Artemis II crew will conduct the first part of a Countdown Demonstration Test at Kennedy, a dress rehearsal for launch day. The crew will don their Orion crew survival system spacesuits and venture to their rocket before being secured inside Orion, which the crew recently named Integrity, simulating the final moments of the countdown. Because the rocket and spacecraft are not yet at the launch pad, the crew will board Orion inside the VAB. The test will serve as a final verification of the timeline for the crew and supporting teams on the ground. A second part of the test, preparing for an emergency at the launch pad, will occur after the rocket and spacecraft roll out to Launch Pad 39B.

The Artemis II crew and ground personnel responsible for launching and flying the mission are preparing to conduct additional integrated simulations across teams and facilities to prepare for any scenario that could arise as the crew of four launches from Florida and flies their approximately 10-day mission.
NASA astronauts Reid Wiseman, Victor Glover, and Christina Koch, and CSA (Canadian Space Agency) astronaut Jeremy Hansen, have a busy schedule over the next several months reviewing procedures for all phases of flight until their preparations are second nature, practicing for different mission scenarios, and maintaining their familiarity with every element of their spacecraft.
Through Artemis, NASA will send astronauts to explore the Moon for scientific discovery, economic benefits, and build the foundation for the first crewed missions to Mars.

A pair of NASA spacecraft ultimately destined for Mars will study how its magnetic environment is impacted by the Sun. The mission also will help the agency prepare for future human exploration of Mars.
NASA’s ESCAPADE (Escape and Plasma Acceleration and Dynamics Explorers) spacecraft launched at 3:55 p.m. EST, Thursday, aboard a Blue Origin New Glenn rocket from Launch Complex 36 at Cape Canaveral Space Force Station in Florida.
“Congratulations to Blue Origin, Rocket Lab, UC Berkeley, and all our partners on the successful launch of ESCAPADE. This heliophysics mission will help reveal how Mars became a desert planet, and how solar eruptions affect the Martian surface,” said acting NASA Administrator Sean Duffy. “Every launch of New Glenn provides data that will be essential when we launch MK-1 through Artemis. All this information will be critical to protect future NASA explorers and invaluable as we evaluate how to deliver on President Trump’s vision of planting the Stars and Stripes on Mars.”
The twin spacecraft, built by Rocket Lab, will investigate how a never-ending, million-mile-per-hour stream of particles from the Sun, known as the solar wind, has gradually stripped away much of the Martian atmosphere, causing the planet to cool and its surface water to evaporate. The mission is led by the University of California, Berkeley.
Ground controllers for the ESCAPADE mission established communications with both spacecraft by 10:35 p.m. EST.
“The ESCAPADE mission is part of our strategy to understand Mars’ past and present so we can send the first astronauts there safely,” said Nicky Fox, associate administrator, Science Mission Directorate at NASA Headquarters in Washington. “Understanding Martian space weather is a top priority for future missions because it helps us protect systems, robots, and most importantly, humans, in extreme environments.”
New Glenn also carried a space communications technology demonstration from Viasat Inc., supporting NASA’s efforts to commercialize next-generation satellite relay services for science missions. Funded by the agency’s Communications Services Project, the demonstration transmitted launch telemetry data from the rocket’s second stage to an operations center on Earth through Viasat’s geostationary satellite network.
Blazing new trails
Recent solar activity, which triggered widespread auroras on Earth, caused a slight delay in launch to prevent solar storms from negatively impacting post-launch spacecraft commissioning. When ESCAPADE arrives at Mars, it will study present-day effects of the solar wind and solar storms on the Red Planet in real time. This will provide insights about Martian space weather and help NASA better understand the conditions astronauts will face when they reach Mars.
“The ESCAPADE spacecraft are now about to embark on a unique journey to Mars never traversed by any other mission,” said Alan Zide, ESCAPADE program executive at NASA Headquarters.
Rather than heading directly to Mars, the twin spacecraft will first head to a location in space a million miles from Earth called Lagrange point 2. Right now, Earth and Mars are on opposite sides of the Sun, which makes it harder to travel from one planet to the other. In November 2026, when Earth and Mars are closely aligned in their orbits, the ESCAPADE spacecraft will loop back to Earth and use Earth’s gravity to slingshot themselves toward Mars.
In the past, Mars missions have waited to launch during a brief window of time when Earth and Mars are aligned, which happens roughly every two years. However, with the type of trajectory ESCAPADE is using, future missions could launch nearly anytime and wait in space, queueing up for their interplanetary departure, until the two planets are in position.
This original “Earth-proximity” or “loiter” orbit also will make ESCAPADE the first mission to ever pass through a distant region of Earth’s magnetotail, part of our planet’s magnetic field that gets stretched out away from the Sun by the solar wind.
Studying Mars in stereo
After a 10-month cruise, ESCAPADE is expected to arrive at Mars in September 2027, becoming the first coordinated dual-spacecraft mission to enter orbit around another planet.
Over several months, the two spacecraft will arrange themselves in their initial science formation, in which the twin spacecraft will follow each other in the same “string-of-pearls” orbit, passing through the same areas in quick succession to investigate for the first time how space weather conditions vary on short timescales. This science campaign will begin in June 2028.
Six months later, both spacecraft will shift into different orbits, with one traveling farther from Mars and the other staying closer to it. Planned to last for five months, this second formation aims to study the solar wind and Mars’ upper atmosphere simultaneously, allowing scientists to investigate how the planet responds to the solar wind in real time.
In addition, ESCAPADE will provide more information about Mars’ ionosphere — a part of the upper atmosphere that future astronauts will rely on to send radio and navigation signals around the planet.
The ESCAPADE mission is funded by NASA’s Heliophysics Division and is part of NASA’s Small Innovative Missions for Planetary Exploration program. NASA’s Goddard Space Flight Center in Greenbelt, Maryland, Embry-Riddle Aeronautical University, and Advanced Space support the mission. NASA’s Launch Services Program, based at Kennedy Space Center in Florida, secured the launch service with Blue Origin under the Venture-class Acquisition of Dedicated and Rideshare contract.

CAPE CANAVERAL, Florida—Another Falcon 9 rocket fired off its launch pad here on Monday night, taking with it another 29 Starlink Internet satellites to orbit.
This was the 94th orbital launch from Florida’s Space Coast so far in 2025, breaking the previous record for the most satellite launches in a calendar year from the world’s busiest spaceport. Monday night’s launch came two days after a Chinese Long March 11 rocket lifted off from an oceangoing platform on the opposite side of the world, marking humanity’s 255th mission to reach orbit this year, a new annual record for global launch activity.
As of Wednesday, a handful of additional missions have pushed the global figure this year to 259, putting the world on pace for around 300 orbital launches by the end of 2025. This will more than double the global tally of 135 orbital launches in 2021.
Un cohete Falcon 9 de SpaceX que transporta las misiones Sonda de Cartografía y Aceleración Interestelar (IMAP, por su acrónimo en inglés) y el Observatorio Carruthers de la Geocorona, ambos de la NASA, y la nave espacial de Seguimiento de la Meteorología Espacial en el Punto de Lagrange 1 (SWFO-L1, por sus siglas en inglés) de la NOAA, despega desde el Centro Espacial Kennedy de la NASA en Florida el miércoles 24 de septiembre de 2025.
La NASA y la Administración Nacional Oceánica y Atmosférica (NOAA, por sus siglas en inglés) lanzaron el miércoles tres nuevas misiones para investigar la influencia del Sol en todo el sistema solar.
A las 7:30 a. m. EDT, un cohete Falcon 9 de SpaceX despegó del Complejo de Lanzamiento 39A del Centro Espacial Kennedy de la NASA en Florida, llevando a bordo las misiones Sonda de Cartografía y Aceleración Interestelar (IMAP, por su acrónimo en inglés) y el Observatorio Carruthers de la Geocorona, ambos de la NASA, y la nave espacial de Seguimiento de la Meteorología Espacial en el Punto de Lagrange 1 (SWFO-L1, por sus siglas en inglés) de la NOAA.
“Este exitoso lanzamiento mejora la preparación de nuestro país ante las condiciones meteorológicas espaciales para proteger mejor nuestros satélites, misiones interplanetarias y astronautas que viajan al espacio de los peligros de la meteorología espacial en todo el sistema solar”, afirmó el administrador interino de la NASA, Sean Duffy. “Esta información será fundamental a medida que nos preparamos para futuras misiones a la Luna y Marte con la intención de mantener a Estados Unidos a la vanguardia en el espacio”.
Estas misiones ayudarán a proteger de las duras condiciones de la meteorología espacial tanto a nuestra tecnología basada en tierra como a nuestros exploradores espaciales humanos y robóticos.
“Mientras Estados Unidos se prepara para enviar a seres humanos de vuelta a la Luna y más adelante a Marte, la NASA y la NOAA están proporcionando la guía definitiva de supervivencia interplanetaria para dar apoyo a este épico viaje de la humanidad”, afirmó Nicola Fox, administradora asociada de la Dirección de Misiones Científicas de la sede central de la NASA en Washington. “Nuestros descubrimientos científicos e innovaciones técnicas se incorporan directamente a nuestro plan de acción know-before-you-go (infórmate antes de ir) para garantizar una presencia humana bien preparada, segura y continua en otros mundos”.
Nueva ciencia para proteger a la sociedad
Cada misión investigará los diferentes efectos de la meteorología espacial y el viento solar, el cual es un flujo continuo de partículas emitidas por el Sol, desde su origen en nuestra estrella hasta el espacio interestelar.
“Estas tres misiones únicas nos ayudarán a conocer nuestro Sol y sus efectos sobre la Tierra mejor que nunca”, afirmó Joe Westlake, director de la División de Heliofísica en la sede central de la NASA. “Este conocimiento es fundamental, ya que la actividad solar afecta directamente a nuestra vida cotidiana, desde las redes eléctricas hasta el GPS. Estas misiones nos ayudarán a garantizar la seguridad y la resiliencia de nuestro mundo interconectado”.
La misión IMAP trazará los límites de la heliosfera, una burbuja inflada por el viento solar que protege nuestro sistema solar de los rayos cósmicos galácticos. Esta es una protección clave que contribuye a que nuestro planeta sea habitable. Además, la nave espacial tomará muestras y medirá las partículas del viento solar que fluyen hacia el exterior desde el Sol, así como las partículas energéticas que fluyen hacia el interior desde los límites de nuestro sistema solar y más allá.
“IMAP nos ayudará a comprender mejor cómo el entorno espacial puede perjudicarnos a nosotros y a nuestras tecnologías, y a descubrir la ciencia de nuestro vecindario solar”, afirmó David McComas, investigador principal de la misión IMAP en la Universidad de Princeton, en Nueva Jersey.
El Observatorio Carruthers de la Geocorona es la primera misión dedicada a medir los cambios en la capa más externa de nuestra atmósfera, la exosfera, la cual juega un papel importante en cómo la Tierra responde a la meteorología espacial. Al estudiar la geocorona —el brillo ultravioleta que emite la exosfera cuando la luz del sol la ilumina— la misión Carruthers revelará cómo la exosfera responde a las tormentas solares y cómo cambia con las estaciones. La misión se basa en el legado del primer instrumento que capturó imágenes de la geocorona, el cual viajó a la Luna a bordo de Apolo 16 y fue construido y diseñado por el científico, inventor, ingeniero y educador Dr. George Carruthers.
“La misión Carruthers nos mostrará cómo funciona la exosfera y nos ayudará a mejorar nuestra capacidad para predecir los efectos de la actividad solar aquí en la Tierra”, dijo Lara Waldrop, investigadora principal de la misión en la Universidad de Illinois en Urbana-Champaign.
La nave SWFO-L1 de la NOAA, la primera de su tipo, está diseñada para ser un observatorio de meteorología espacial operativo a tiempo completo. Al vigilar la actividad solar y las condiciones espaciales cerca de la Tierra las 24 horas del día, los 7 días de la semana, sin interrupciones ni obstrucciones, SWFO-L1 proporcionará pronósticos de meteorología espacial más rápidos y precisos que nunca.
“Se trata del primero de una nueva generación de observatorios de meteorología espacial de la NOAA dedicados a operaciones ininterrumpidas, que trabajarán para evitar lagunas en la continuidad. Las observaciones en tiempo real de SWFO-L1 proporcionarán a los operadores los datos fiables necesarios para emitir alertas tempranas, de modo que los responsables de la toma de decisiones puedan actuar con antelación para proteger las infraestructuras vitales, los intereses económicos y la seguridad nacional en la Tierra y en el espacio. Se trata de proteger a la sociedad contra los peligros de la meteorología espacial”, dijo Richard Ullman, subdirector de la Oficina de Observaciones de la Meteorología Espacial de la NOAA
Siguientes pasos
En las horas posteriores al lanzamiento, las tres naves espaciales se desplegaron desde el cohete con éxito y enviaron señales a la Tierra para confirmar que están activas y funcionando correctamente.
Durante los próximos meses, los satélites se dirigirán a su destino, un lugar situado entre la Tierra y el Sol, a unos 1,6 millones de kilómetros de la Tierra, denominado punto de Lagrange 1 (L1). Se espera que lleguen en enero y, una vez completadas las comprobaciones y calibraciones de sus instrumentos, comiencen sus misiones para comprender mejor la meteorología espacial y proteger a la humanidad.

A SpaceX Falcon 9 rocket carrying NASA’s IMAP (Interstellar Mapping and Acceleration Probe), Carruthers Geocorona Observatory, and the National Oceanic and Atmospheric Administration’s (NOAA) Space Weather Follow On-Lagrange 1 (SWFO-L1) missions launches from the agency’s Kennedy Space Center in Florida, Wednesday, Sept. 24, 2025.
NASA and the National Oceanic and Atmospheric Administration (NOAA) launched three new missions Wednesday to investigate the Sun’s influence across the solar system.
At 7:30 a.m. EDT, a SpaceX Falcon 9 rocket lifted off from Launch Complex 39A at NASA’s Kennedy Space Center in Florida carrying the agency’s IMAP (Interstellar Mapping and Acceleration Probe), Carruthers Geocorona Observatory, and NOAA’s SWFO-L1 (Space Weather Follow On-Lagrange 1) spacecraft.
“This successful launch advances the space weather readiness of our nation to better protect our satellites, interplanetary missions, and space-faring astronauts from the dangers of space weather throughout the solar system,” said acting NASA Administrator Sean Duffy, “This insight will be critical as we prepare for future missions to the Moon and Mars in our endeavor to keep America first in space.”
These missions will help safeguard both our ground-based technology, as well as our human and robotic space explorers from the harsh conditions known of space weather.
“As the United States prepares to send humans back to the Moon and onward to Mars, NASA and NOAA are providing the ultimate interplanetary survival guide to support humanity’s epic journey along the way,” said Nicola Fox, associate administrator, Science Mission Directorate at NASA Headquarters in Washington. “Our scientific discoveries and technical innovations directly feed into our know-before-you-go roadmap to ensure a prepared, safe, and sustained human presence on other worlds.”
New science to protect society
Each mission will investigate different effects of space weather and the solar wind, which is a continuous stream of particles emitted by the Sun, from their origins at the Sun all the way outward to interstellar space.
“These three unique missions will help us get to know our Sun and its effects on Earth better than ever before,” said Joe Westlake, Heliophysics Division director at NASA Headquarters. “This knowledge is critical because the Sun’s activity directly impacts our daily lives, from power grids to GPS. These missions will help us ensure the safety and resilience of our interconnected world.”
The IMAP mission will chart the boundary of the heliosphere, a bubble inflated by the solar wind that shields our solar system from galactic cosmic rays — a key protection that helps make our planet habitable. In addition, the spacecraft will sample and measure solar wind particles streaming outward from the Sun, as well as energetic particles streaming inward from the boundary of our solar system and beyond.
“IMAP will help us better understand how the space environment can harm us and our technologies, and discover the science of our solar neighborhood,” said David McComas, IMAP mission principal investigator at Princeton University in New Jersey.
The Carruthers Geocorona Observatory is the first mission dedicated to recording changes in the outermost layer of our atmosphere, the exosphere, which plays an important role in Earth’s response to space weather. By studying the geocorona — the ultraviolet glow given off by the exosphere when sunlight shines on it — the Carruthers mission will reveal how the exosphere responds to solar storms and how it changes with the seasons. The mission builds on the legacy of the first instrument to image the geocorona, which flew to the Moon aboard Apollo 16 and was built and designed by scientist, inventor, engineer, and educator Dr. George Carruthers.
“The Carruthers mission will show us how the exosphere works and will help improve our ability to predict the impacts of solar activity here on Earth,” said Lara Waldrop, the mission’s principal investigator at the University of Illinois at Urbana-Champaign.
The first of its kind, NOAA’s SWFO-L1 is designed to be a full-time operational space weather observatory. By keeping a watchful eye on the Sun’s activity and space conditions near Earth 24/7, and without interruption or obstruction, SWFO-L1 will provide quicker and more accurate space weather forecasts than ever before.
“This is the first of a new generation of NOAA space weather observatories dedicated to 24/7 operations, working to avoid gaps in continuity. Real-time observations from SWFO-L1 will give operators the trusted data necessary to issue advance warnings so that decision-makers can take early action to protect vital infrastructure, economic interests, and national security on Earth and in space. It’s about safeguarding society against space weather hazards,” said Richard Ullman, deputy director of the Office of Space Weather Observations at NOAA.
Next steps
In the hours after launch, all three spacecraft successfully deployed from the rocket and sent signals to Earth to confirm they’re active and working well.
Over the next few months, the spacecraft will make their way to their destination — a location between Earth and the Sun, about a million miles from Earth, called Lagrange point 1 (L1). They should arrive by January and, once their instrument checkouts and calibrations are complete, begin their missions to better understand space weather and protect humanity.
David McComas of Princeton University leads the IMAP mission with an international team of 27 partner institutions. The Johns Hopkins Applied Physics Laboratory in Laurel, Maryland, built the spacecraft and will operate the mission.
The Carruthers Geocorona Observatory mission is led by Lara Waldrop from the University of Illinois Urbana-Champaign. Mission implementation is led by the Space Sciences Laboratory at University of California, Berkeley, which also designed and built the two ultraviolet imagers. BAE Systems designed and built the Carruthers spacecraft.
The Explorers and Heliophysics Projects Division at NASA’s Goddard Space Flight Center in Greenbelt, Maryland, manages the IMAP and Carruthers Geocorona Observatory missions for NASA’s Science Mission Directorate.
The SWFO-L1 mission is managed by NOAA and developed with NASA Goddard, and commercial partners. NASA’s Launch Services Program, based at NASA Kennedy, manages the launch service for the missions.
All the pieces are stacking up – literally – for NASA’s first crewed mission of the Artemis program coming in 2026.
Teams are finishing integration of the Orion spacecraft for the Artemis II test flight with its launch abort system on Sept. 17 inside the Launch Abort System Facility at NASA’s Kennedy Space Center in Florida. The 44-foot-tall tower-like abort structure would swiftly carry the four-person crew inside Orion to safety in the unlikely event of an emergency during launch or ascent atop the SLS (Space Launch System) rocket.
Over the next few weeks, teams will complete remaining closeout activities before moving the spacecraft to its final stop before the launch pad: the agency’s Vehicle Assembly Building. There it will be added to the top of the rocket, before the finished stack is rolled out to the launch pad on its way to the Moon.
The abort system is comprised of three solid rocket motors: the jettison, attitude, and abort motors. In the case of an emergency, these motors work together to propel the astronauts inside Orion’s crew module to safety: the abort motor pulls the crew module away from the launch vehicle; the attitude control motor steers and orients the capsule; then the jettison motor ignites to separate the abort system from the crew module prior to parachute deployment. During a normal launch, Orion will shed the abort system and leave it behind once the crew is safely through the most dynamic part of ascent, leaving Orion thousands of pounds lighter for the rest of its journey.
Technicians completed integrating NASA’s Carruthers Geocorona Observatory and the National Oceanic and Atmospheric Administration’s (NOAA) Space Weather Follow-On Lagrange 1 (SWFO-L1) satellite to an Evolved Expendable Launch Vehicle Secondary Payload Adapter ring at the Astrotech Space Operations Facility near NASA’s Kennedy Space Center in Florida on Sept. 4.
Integrating the rideshares to the ring precedes the next prelaunch launch milestone: attaching NASA’s IMAP (Interstellar Mapping and Acceleration Probe) heliosphere mapping observatory to a payload adapter that connects to the ring. This configuration allows all three spacecraft to launch atop a single SpaceX Falcon 9 rocket, maximizing efficiency by sharing the ride to space.
The Carruthers observatory will capture light from Earth’s geocorona, the part of the outer atmosphere that emits ultraviolet light. The observations will advance our understanding of space weather, planetary atmospheric evolution, and the long-term history of water on Earth.
The SWFO-L1 satellite will keep a watchful eye on the Sun and the near-Earth environment for space weather activity. It is the first NOAA satellite designed specifically for and fully dedicated to continuous space weather observations. It will serve as an early warning beacon for destructive space weather events that could impact our technological dependent infrastructure and industries.
The spacecraft will launch together aboard a SpaceX Falcon 9 rocket no earlier than 7:32 a.m. EDT on Tuesday, Sept. 23, from Launch Complex 39A at NASA Kennedy.
