LEXI will study changes in the magnetosphere and help us learn more about how it interacts with a stream of particles from the Sun called the solar wind, which can pose hazards for Artemis astronauts traveling to the Moon.Learn more about LEXI and its CLPS (Commercial Lunar Payload Services) flight to the Moon from Hyunju Connor, LEXI co-investigator at NASA’s Goddard Space Flight Center.More on LEXI: https://science.nasa.gov/science-research/heliophysics/nasas-lexi-will-provide-x-ray-vision-of-earths-magnetosphere/ || ", "hits": 160 }, { "id": 13954, "url": "https://svs.gsfc.nasa.gov/13954/", "result_type": "Produced Video", "release_date": "2021-10-06T04:00:00-04:00", "title": "With NASA Data, Researchers Find Standing Waves at Edge of Earth’s Magnetic Bubble", "description": "Earth sails the solar system in a ship of its own making: the magnetosphere, the magnetic field that envelops and protects our planet. The celestial sea we find ourselves in is filled with charged particles flowing from the Sun, known as the solar wind. Just as ocean waves follow the wind, scientists expected that waves traveling along the magnetosphere should ripple in the direction of the solar wind. But a new study reveals some waves do just the opposite.Studying these magnetospheric waves, which transport energy, helps scientists understand the complicated ways that solar activity plays out in the space around Earth. Changing conditions in space driven by the Sun are known as space weather. That weather can impact our technology from communications satellites in orbit to power lines on the ground. “Understanding the boundaries of any system is a key problem,” said Martin Archer, a space physicist at Imperial College London who led the new study, published today in Nature Communications. “That’s how stuff gets in: energy, momentum, matter.” || ", "hits": 207 }, { "id": 4639, "url": "https://svs.gsfc.nasa.gov/4639/", "result_type": "Visualization", "release_date": "2018-05-09T13:00:00-04:00", "title": "MMS Sees a New Type of Reconnection", "description": "The Magnetospheric Multiscale (MMS) mission consists of four identical satellites that traverse various regions of Earth's magnetosphere measuring the particles and electric and magnetic field which influence them.In the turbulent plasma between Earth's magnetopause and bow shock, a region called the magnetosheath, the MMS satellite constellation has measured multiple jets of energetic electrons between magnetic bubbles. This appears to be a new 'flavor' of magnetic reconnection based on electrons and occuring on smaller time and spatial scales than the standard model of magnetic reconnection with ions.In these data visualizations, the arrows represent the data collected by the spacecraft. To better comprehend changes as the spacecraft moves along, the data are allowed to 'echo' along the spacecraft trail. The length of the vectors represent the relative magnitude of the vector. However, the electron and proton vectors are scaled so equal velocities correspond to vectors of equal magnitude.Magenta represents the direction and magnitude of the magnetic field at the spacecraft position.Green represents the direction and magnitude of the net electric current created by the motion of the electrons and ions measured at the spacecraft position.The four MMS spacecraft are represented by colored spheres, corresponding to the plotted data lines in the lower graphicMMS1MMS2MMS3MMS4The clocks on MMS are synchronized for the TAI (International Atomic Time) system provided through the Global Positioning System (GPS) satellites.

The plasmapause marks the outer boundary of this region. This colder plasma is more easily moved by the electric fields created by strong solar storms. In the Halloween 2003 event, these fields convected some of the cold plasma out to the magnetopause (gray, semi-transparent surface) and reduced the size of the cold plasma region near the Earth. For this visualization, the 3-dimensional structure was constructed from the equatorial profile of the plasmapause (as measured by IMAGE/EUV data) by extending the region along field lines of a simple dipole field.NOTE: This visualization shows the Earth's magnetic dipole field lines rotating rigidly with the Earth. Technically, this is inaccurate. Ions and electrons in the lower atmosphere can create currents which can make these lines 'drag' with Earth's rotation, but this will occur mostly near the Earth and not higher up. More details on this process can be found in the FAQ at the The Exploration of the Earth's Magnetosphere web site, Does the Earth's magnetic field rotate?. || ", "hits": 38 } ] }
