La sonda IMAP de la NASA utilizará diez instrumentos científicos para estudiar y mapear la heliosfera, una vasta burbuja magnética que rodea al Sol y protege nuestro sistema solar de la radiación proveniente del espacio interestelar. Esta misión y sus dos compañeros de viaje orbitarán el Sol cerca del punto de Lagrange 1, a aproximadamente 1,6 millones de kilómetros (un millón de millas) de la Tierra, donde escaneará la heliosfera, analizará la composición de partículas cargadas e investigará cómo esas partículas se mueven a través del sistema solar. Esto proporcionará información sobre cómo el Sol acelera las partículas cargadas, aportando información esencial para comprender el entorno meteorológico espacial en todo el sistema solar. IMAP también monitoreará continuamente el viento solar y la radiación cósmica. La comunidad científica podrá usar estos datos para evaluar capacidades nuevas y mejoradas para herramientas y modelos de predicción de la meteorología espacial, que son vitales para la salud de los humanos que exploran el espacio y la longevidad de sistemas tecnológicos, como satélites y redes eléctricas, que pueden afectar la vida en la Tierra.
El Observatorio Carruthers de la Geocorona de la agencia es un pequeño satélite concebido para estudiar la exosfera, la parte más externa de la atmósfera de la Tierra. Utilizando cámaras ultravioletas, monitoreará cómo la meteorología espacial del Sol impacta la exosfera, la cual juega un papel crucial en la protección de la Tierra contra eventos de meteorología espacial que pueden afectar satélites, comunicaciones y líneas eléctricas. La exosfera, una nube de hidrógeno neutro que se extiende hasta la Luna y posiblemente más allá, se crea por la descomposición del agua y el metano por la luz ultravioleta del Sol, y su brillo, conocido como la geocorona, solo se ha observado a nivel mundial cuatro veces antes de esta misión.
La misión SWFO-L1, gestionada por la NOAA y desarrollada con el Centro de Vuelo Espacial Goddard de NASA en Greenbelt, Maryland, y socios comerciales, utilizará un conjunto de instrumentos para proporcionar mediciones en tiempo real del viento solar, junto con un coronógrafo compacto para detectar eyecciones de masa coronal del Sol. El observatorio, que sirve como baliza de alerta temprana para fenómenos meteorológicos espaciales potencialmente destructivos, permitirá pronósticos más rápidos y precisos. Sus datos, disponibles las 24 horas del día, los 7 días de la semana, ayudarán al Centro de Predicción Meteorológica Espacial de la NOAA a proteger infraestructuras vitales, intereses económicos y la seguridad nacional, tanto en la Tierra como en el espacio.
David McComas, profesor de la Universidad de Princeton, lidera la misión IMAP con un equipo internacional de 25 instituciones asociadas. El Laboratorio de Física Aplicada Johns Hopkins en Laurel, Maryland, construyó la nave espacial y opera la misión. IMAP de la NASA es la quinta misión en el portafolio del programa de Sondas Solares Terrestres de la NASA. La División de Exploradores y Proyectos de Heliofísica en el centro Goddard de la NASA gestiona el programa para la División de Heliofísica de la Dirección de Misiones Científicas de la NASA.

NASA astronaut Nichole Ayers took this photo of California’s San Francisco Bay Area surrounded by the cities of San Francisco, Oakland, and San Jose, and their suburbs on Aug. 3, 2025. At the time, the International Space Station orbited 260 miles above the Golden State.
The International Space Station serves as a unique platform for observing Earth with both hands-on and automated equipment. Station crew members have produced hundreds of thousands of images, recording phenomena such as storms in real time, observing natural events such as volcanic eruptions as they happen, and providing input to ground personnel for programming automated Earth-sensing systems.
In its third decade of continuous human presence, the space station has a far-reaching impact as a microgravity lab hosting technology, demonstrations, and scientific investigations from a range of fields. The research done on the orbiting laboratory will inform long-duration missions like Artemis and future human expeditions to Mars.

Close-Up Views of NASA’s DART Impact to Inform Planetary Defense

Close-Up Views of NASA’s DART Impact to Inform Planetary Defense Photos taken by the Italian LICIACube, short for the LICIA CubeSat for Imaging of Asteroids. These offer the closest, most detailed observations of NASA’s DART (Double Asteroid Redirection Test) impact aftermath to date. The photo on the left was taken roughly 2 minutes and 40 seconds after impact, as the satellite flew past the Didymos system. The photo on the right was taken 20 seconds later, as LICIACube was leaving the scene. The larger body, near the top of each image is Didymos. The smaller body in the lower half of each image is Dimorphos, enveloped by the cloud of rocky debris created by DART’s impact. NASA/ASI/University of Maryland
On Sept. 11, 2022, engineers at a flight control center in Turin, Italy, sent a radio signal into deep space. Its destination was NASA’s DART (Double Asteroid Redirection Test) spacecraft flying toward an asteroid more than 5 million miles away.
The message prompted the spacecraft to execute a series of pre-programmed commands that caused a small, shoebox-sized satellite contributed by the Italian Space Agency (ASI), called LICIACube, to detach from DART.
Fifteen days later, when DART’s journey ended in an intentional head-on collision with near-Earth asteroid Dimorphos, LICIACube flew past the asteroid to snap a series of photos, providing researchers with the only on-site observations of the world’s first demonstration of an asteroid deflection.
After analyzing LICIACube’s images, NASA and ASI scientists report on Aug. 21 in the Planetary Science Journal that an estimated 35.3 million pounds (16 million kilograms) of dust and rocks spewed from the asteroid as a result of the crash, refining previous estimates that were based on data from ground and space-based observations.
While the debris shed from the asteroid amounted to less than 0.5% of its total mass, it was still 30,000 times greater than the mass of the spacecraft. The impact of the debris on Dimorphos’ trajectory was dramatic: shortly after the collision, the DART team determined that the flying rubble gave Dimorphos a shove several times stronger than the hit from the spacecraft itself.
“The plume of material released from the asteroid was like a short burst from a rocket engine,” said Ramin Lolachi, a research scientist who led the study from NASA’s Goddard Space Flight Center in Greenbelt, Maryland.
The important takeaway from the DART mission is that a small, lightweight spacecraft can dramatically alter the path of an asteroid of similar size and composition to Dimorphos, which is a “rubble-pile” asteroid — or a loose, porous collection of rocky material bound together weakly by gravity.
“We expect that a lot of near-Earth asteroids have a similar structure to Dimorphos,” said Dave Glenar, a planetary scientist at the University of Maryland, Baltimore County, who participated in the study. “So, this extra push from the debris plume is critical to consider when building future spacecraft to deflect asteroids from Earth.”
NASA chose Dimorphos, which poses no threat to Earth, as the mission target due to its relationship with another, larger asteroid named Didymos. Dimorphos orbits Didymos in a binary asteroid system, much like the Moon orbits Earth. Critically, the pair’s position relative to Earth allowed astronomers to measure the duration of the moonlet’s orbit before and after the collision.
Ground and space-based observations revealed that DART shortened Dimorphos’ orbit by 33 minutes. But these long-range observations, made from 6.8 million miles (10.9 million kilometers) away, were too distant to support a detailed study of the impact debris. That was LICIACube’s job.
After DART’s impact, LICIACube had just 60 seconds to make its most critical observations. Barreling past the asteroid at 15,000 miles (21,140 kilometers) per hour, the spacecraft took a snapshot of the debris roughly once every three seconds. Its closest image was taken just 53 miles (85.3 km) from Dimorphos’ surface.
The short distance between LICIACube and Dimorphos provided a unique advantage, allowing the cubesat to capture detailed images of the dusty debris from multiple angles.
The research team studied a series of 18 LICIAcube images. The first images in the sequence showed LICIACube’s head-on approach. From this angle, the plume was brightly illuminated by direct sunlight. As the spacecraft glided past the asteroid, its camera pivoted to keep the plume in view.
As LICIACube looked back at the asteroid, sunlight filtered through the dense cloud of debris, and the plume’s brightness faded. This suggested the plume was made of mostly large particles — about a millimeter or more across — which reflect less light than tiny dust grains.
Since the innermost parts of the plume were so thick with debris that they were completely opaque, the scientists used models to estimate the number of particles that were hidden from view. Data from other rubble-pile asteroids, including pieces of Bennu delivered to Earth in 2023 by NASA’s OSIRIS-REx spacecraft, and laboratory experiments helped refine the estimate.
“We estimated that this hidden material accounted for almost 45% of the plume’s total mass,” said Timothy Stubbs, a planetary scientist at NASA Goddard who was involved with the study.
While DART showed that a high-speed collision with a spacecraft can change an asteroid’s trajectory, Stubbs and his colleagues note that different asteroid types, such as those made of stronger, more tightly packed material, might respond differently to a DART-like impact. “Every time we interact with an asteroid, we find something that surprises us, so there’s a lot more work to do,” said Stubbs. “But DART is a big step forward for planetary defense.”
The Johns Hopkins Applied Physics Laboratory in Laurel, Maryland, managed the DART mission and operated the spacecraft for NASA’s Planetary Defense Coordination Office as a project of the agency’s Planetary Missions Program Office.

NASA’s IMAP will use 10 science instruments to study and map the heliosphere, a vast magnetic bubble surrounding the Sun protecting our solar system from radiation incoming from interstellar space. This mission and its two rideshares will orbit the Sun near Lagrange point 1, about one million miles from Earth, where it will scan the heliosphere, analyze the composition of charged particles, and investigate how those particles move through the solar system. This will provide information on how the Sun accelerates charged particles, filling in essential puzzle pieces to understand the space weather environment across the solar system. The IMAP spacecraft also will continuously monitor solar wind and cosmic radiation. Scientists can use this information to evaluate new and improved capabilities for space weather prediction tools and models, which are vital for the health of human space explorers and the longevity of technological systems, like satellites and power grids, that can affect life on Earth.
The agency’s Carruthers Geocorona Observatory is a small satellite set to study the exosphere, the outermost part of Earth’s atmosphere. Using ultraviolet cameras, it will monitor how space weather from the Sun impacts the exosphere, which plays a crucial role in protecting Earth from space weather events that can affect satellites, communications, and power lines. The exosphere, a cloud of neutral hydrogen extending to the Moon and possibly beyond, is created by the breakdown of water and methane by ultraviolet light from the Sun, and its glow, known as the geocorona, has been observed globally only four times before this mission.
The SWFO-L1 mission, managed by NOAA and developed with NASA’s Goddard Space Flight Center in Greenbelt, Maryland, and commercial partners, will use a suite of instruments to provide real-time measurements of solar wind, along with a compact coronagraph to detect coronal mass ejections from the Sun. The observatory, serving as an early warning beacon for potentially destructive space weather events, will enable faster and more accurate forecasts. Its 24/7 data will support NOAA’s Space Weather Prediction Center in protecting vital infrastructure, economic interests, and national security, both on Earth and in space.
David McComas, professor, Princeton University, leads the IMAP mission with an international team of 25 partner institutions. The Johns Hopkins Applied Physics Laboratory in Laurel, Maryland, built the spacecraft and operates the mission. NASA’s IMAP is the fifth mission in NASA’s Solar Terrestrial Probes program portfolio. The Explorers and Heliophysics Project Division at NASA Goddard manages the program for the agency’s Heliophysics Division of NASA’s Science Mission Directorate.
NASA’s Launch Services Program, based at NASA Kennedy, manages the launch service for the mission.
