Dec 10, 2021 · Space weather refers to conditions in the solar system produced by the Sun’s activity. Just as weather is always occurring on Earth, space weather is ongoing. Even without major solar activity, satellites and communications systems can be impacted by variability in the density and composition of the near-earth environment. “Space isn’t ...

The Heliophysics Division Space Weather Science Application (SWxSA) initiative expands the role of NASA in space weather science under a single budget element and supports the multi-agency National Space Weather Strategy and Action Plan. It competes ideas and products, leverages existing Agency capabilities, collaborates with other national and ...
Jun 11, 2024 · Aurora and airglow are seen from the International Space Station in 2015. NASA has selected three proposals for concept studies of missions to investigate the complex system of space weather that surrounds our planet and how it’s connected to Earth’s atmosphere. The three concepts propose how to enact the DYNAMIC (Dynamical Neutral ...
Definition of Space Weather: The conditions on the sun, in space, and in our upper atmosphere that can influence the performance and reliability of space- borne and ground- based technological systems and endanger human life or health.

Quite different from your average terrestrial rain or snow, space weather in our solar system is composed of radiation and particles from the sun. The sun is made up of superhot electrically charged plasma, the fourth state of matter. Plasma constantly streams toward the planets as solar wind, pouring energy into near-Earth space. That's not all th...
Earth has a strong, large magnetic field produced by charged molten iron churning in its core. That field keeps away most of the charged solar wind streaming toward Earth, just like an umbrella works in a rainstorm. The area within the safety of Earth's magnetic fieldis called the magnetosphere. Earth's magnetosphere is quite large and strong. On t...
As Halford explains, the protection offered by the magnetosphere isn't perfect. There are three main ways that an explosion on the sun's surface can affect Earth. 1. Radio blackout storm: This type of storm, generated by electromagnetic energy—light, mostly in wavelengths that are invisible to human eyes—is most likely to occur following a solar fl...
A variety of agencies keep close watch on space weather. NOAA's Space Weather Prediction Center is the U.S. government's official source for space weather forecasts. NASA Heliophysics coordinates research efforts with NOAA, the National Science Foundation, the U.S. Geological Survey, and the U.S. Air Force Research Laboratory on the National Space ...
Scientists and federal government organizations monitor and prepare for space weather events. Engineers work to build "rad-hard," or radiation resistant, satellites. Astronauts may need to take shelter during certain space weather events. Power grid operators may implement safeguards against geomagnetic storm effects. The United States government m...
Feb 25, 2019 · NASA has selected a new mission that will help scientists understand and, ultimately, forecast the vast space weather system around our planet. Space weather is important because it can have profound impacts – affecting technology and astronauts in space, disrupting radio communications and, at its most severe, overwhelming power grids.
