"description": "The heliosphere, the massive bubble created by our Sun, is like our “house” in space. It shelters us from harsh weather outside and regulates the environment inside. Without our heliosphere, Earth may never have developed life at all. But there’s a lot we still don’t know about our cosmic home. How big is it, and what is it shaped like? How does it compare to the “houses” created by other stars? A new NASA mission will soon unlock answers to these questions and more. Launching as early as Sept. 23, NASA’s Interstellar Mapping and Acceleration Probe will help us construct the “blueprints” or our home in space. This three-part series explores how we learn about our heliosphere, how it protects us, and how it advances the search for life elsewhere in the Universe. || ",

"description": "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. Launching September 23, 2025, from NASA’s Kennedy Space Center in Florida, 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 missions will each study 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 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 from space weather threats.Watch the launch with NASA from anywhere in the world. We will provide live broadcast coverage on September 23 from 6:40 a.m. to about 9:15 a.m. EDT (1040 to 1415 UTC) on NASA+, Amazon Prime, Twitch, YouTube, and more.

An ENA is a type of uncharged particle formed when an energetic positively charged ion runs into a slow-moving neutral atom. The ion picks up an extra negatively charged electron in the collision, making it neutral — hence the name energetic neutral atom. This process frequently happens wherever there is plasma in space, such as throughout the heliosphere, including its boundary.The IMAP-Lo, IMAP-HI, and IMAP-Ultra instruments on IMAP are imaging the energies and composition of ENAs.Learn more about IMAP: https://science.nasa.gov/mission/imap/ || ",

The mission will study how the Sun shapes the boundaries of the heliosphere, the bubble around our solar system. A semitrailer transported the spacecraft from NASA’s Marshall Space Flight Center in Huntsville, Alabama, after completing thermal vacuum testing, which simulates the harsh conditions of space, at the X-ray and Cryogenic Facility. Astrotech provides the facility and technicians to prepare the spacecraft for launch, including fueling and encapsulation. The IMAP spacecraft launched Sept. 24, 2025, on a SpaceX Falcon 9 rocket from Launch Complex 39A at NASA Kennedy. || ",

Every 11 years, the Sun’s activity ramps up and down in what’s known as the solar cycle. As the Sun reaches its peak activity level, called solar maximum, the heliosphere expands. During this time, the heliosphere’s protective shield is strengthened by the increase in particles and magnetic fields from the Sun. As a result, fewer damaging particles from the galaxy, such as galactic cosmic rays, are able to penetrate into the heliosphere. As the Sun ramps down into a low level of activity, called solar minimum, the heliosphere shrinks and more cosmic rays are able to enter the heliosphere. || ",

"description": "The sun sends out a constant flow of charged particles called the solar wind, which ultimately travels past all the planets to some three times the distance to Pluto before being impeded by the interstellar medium. This forms a giant bubble around the sun and its planets, known as the heliosphere. NASA studies the heliosphere to better understand the fundamental physics of the space surrounding us - which, in turn, provides information regarding space throughout the rest of the universe, as well as regarding what makes planets habitable.The solar wind is a gas of charged particles known as plasma, a state of matter governed by its own set physical laws just as the more common solids, liquids, and gases are. As the solar wind sweeps out into space, it creates a space environment filled with radiation as well as magnetic fields that trail all the way back to the sun. This space environment is augmented by interstellar cosmic rays and occasional concentrated clouds of solar material that burst off the sun, known as coronal mass ejections.This complex environment surrounds the planets and ultimately has a crucial effect on the formation, evolution, and destiny of planetary systems. For one thing, our heliosphere acts as a giant shield, protecting the planets from galactic cosmic radiation. Earth is additionally shielded by its own magnetic field, the magnetosphere, which protects us not only from solar and cosmic particle radiation but also from erosion of the atmosphere by the solar wind. Planets without a shielding magnetic field, such as Mars and Venus, are exposed to such processes and have evolved differently.NASA's studies of the heliosphere include research into: how the solar wind behaves near Earth; what causes and sustains magnetic and electric fields around other planets; how does the heliosphere interact with the interstellar medium; what do the boundaries of the heliosphere look like; what is the origin and evolution of the solar wind and the interstellar cosmic rays; and what contributes to the habitability of exoplanets.The field is, therefore, intensely cross-disciplinary. Heliospheric research often works hand in hand with planetary scientists, astrophysicists, astrobiologists, and space weather researchers.NASA heliophysics missions contributing to heliospheric research are: the Advanced Composition Explorer; NOAA's Deep Space Climate Observatory, the Interstellar Boundary Explorer, the Solar Terrestrial Relations Observatory; Voyager, and Wind. || ",

Such eruptions can have multiple components, including X rays, coronal mass ejection plasma, and solar energetic particles – bursts or events of fast-moving particles. These events can occur suddenly and have the potential to rapidly change the radiation environment of wide swaths of the inner solar system where they may create hazardous conditions. Not only are such conditions dangerous for humans in space, but the intense ionizing radiation can also affect the interior of spacecraft, including sensitive electronics. Solar energetic particles can reach all regions of near-Earth space, including the lunar surface, with the exception of low-altitude and low-latitude Earth orbit, where the Earth’s magnetic field is strong enough to form a protective barrier. || ",

"alt_text": "An intense solar eruptive event has many parts. This animation starts with a solar flare, which sends light and energy in straight paths, traveling at the speed of light. A coronal mass ejection, or CME, appears next – this is a giant cloud of solar particles that also expands in a straight direction with speeds up to two thousand miles an hour. The eruption also generates solar energetic particles, with speeds nearly reaching the speed of light, following the spiral shape of the solar wind’s magnetic fields into interplanetary space. ",

"description": "This animation shows a charged solar particle's path leaving the sun, while following the magnetic field lines out to the heliosheath. The solar particle hits a hydrogen atom, stealing its electron and becoming neutral. We then follow it until we see it hit one of IBEX's detectors. || ",

"title": "Solar Wind Animations",
"description": "The Sun releases a constant stream of charged particles, called the solar wind. The solar wind originates in the outermost layer of the Sun’s atmosphere, the corona, when plasma is heated to a point that the Sun’s gravity can’t hold it down. When this plasma escapes – often reaching speeds of over one million miles per hour – it drags the Sun’s magnetic out across the solar system. When the solar wind encounters Earth, it is deflected by our planet's magnetic shield, causing most of the solar wind's energetic particles to flow around and beyond us. However, some of these high-energy particles can sneak past Earth’s natural magnetic defenses and produce hazardous conditions for satellites and astronauts, as well as power grids and infrastructure on Earth.Learn more about the solar wind: https://science.nasa.gov/sun/what-is-the-solar-wind/ || ",
