            "description": "We see auroras at the tail end of a great journey energy makes from the sun. Now, scientists have mapped the details of this journey better than ever before. Auroras are produced when fast-moving particles funnel toward the poles and collide with gases in Earth’s atmosphere. But what shifts these particles into high gear is a shockwave of energy that’s caused by the crossing and realignment of magnetic field lines on the night side of the planet. This process, called magnetic reconnection, takes place in a distant region of the vast magnetic environment that surrounds Earth known as the magnetotail. Taking advantage of an unprecedented alignment of eight satellites, scientists tracked the flow of energy from the sun to the magnetotail and back to Earth for the first time. Watch the video to see this journey unfold. || ",

            "description": "In July of 2012, a fleet of spacecraft studying Earth's magnetosphere were in an ideal alignment to detect a particle flow predicted in magnetospheric models. The grey mesh shell structure represents the approximate location of the magnetopause.In this visualization, THEMIS, ARTEMIS (in orbit around the Moon), and Geotail, as well as the particle detectors on the GOES-13 and GOES-15 satellites achieved a good alignment around 09:45 on July 3, 2012 to detect one of the particle flows predicted by magnetospheric models. || ",

            "description": "Mathematical models of Earth's magnetosphere have become increasingly more complex and accurate. They have sufficient detail to illustrate many small-scale phenomena.In this simulation run of the Geospace General Circulation Model (GGCM) we see new details that have been observed by in situ satellites. As the solar wind is deflected around Earth's magnetosphere (the 'bubble' of plasma surrounding Earth held by Earth's magnetic field), plasma flows within the bubble can change. In the graphics below, physical variables such as magnetic field and electric currents are plotted. With these variables, we overlay the net flow of the plasma (arrows), subjected to selection criteria to separate flows of plasma away from Earth and towards Earth. Green arrows are low-speed flows (below about 150 kilometers/second), while red arrows correspond to high-speed plasmal flows (about 300 kilometers/second and higher). || ",

            "description": "Taking advantage of an unprecedented alignment of eight satellites through the vast magnetic environment that surrounds Earth in space, including NASA's ARTEMIS and THEMIS, scientists now have comprehensive details of the energy's journey through a process that forms the aurora, called a substorm. Their results showed that small events unfolding over the course of a millisecond can result in energy flows that last up to half an hour and cover an area 10 times larger than Earth.Trying to understand how gigantic explosions on the sun can create space weather effects involves tracking energy from the original event all the way to Earth. It's not unlike keeping tabs on a character in a play with many costume changes, because the energy changes form frequently along its journey: magnetic energy causes eruptions that lead to kinetic energy as particles hurtle away, or thermal energy as the particles heat up. Near Earth, the energy can change through all these various forms once again.Most of the large and small features of substorms take place largely in the portion of Earth's magnetic environment called the magnetotail. Earth sits inside a large magnetic bubble called the magnetosphere. As Earth orbits around the sun, the solar wind from the sun streams past the bubble, stretching it outward into a teardrop. The magnetotail is the long point of the teardrop trailing out to more than 1 million miles on the night side of Earth. The moon orbits Earth much closer, some 240,000 miles away, crossing in and out of the magnetotail. || ",

The apogee of the orbit takes the spacecraft just beyond the bow shock of Earth's magnetosphere. This enables the closely spaced satellites to measure the thickness of the different regions that they encounter. || ",

            "description": "This visualization combines simulations of the THEMIS (Time History of Events and Macroscale Interactions during Substorms) mission orbits with a GGCM (Geospace General Circulation Model) simulation.  It illustrates how the five THEMIS satellites will work together to detect substorm events in the magnetosphere.  One goal of the THEMIS mission is to test how these substorm events are related to the formation of the aurora.This mission consists of five identical spacecraft (usually designated P1, P2, P3, P4 and P5) with orbits aligned so they reach their apogee along the same line from the Earth.  This alignment remains fixed in space so as the Earth moves around the Sun, the constellation of spacecraft will extend on the nightside of the Earth in winter to sample the Earth's magnetosphere, and on the dayside of the Earth in summer to sample the incoming solar wind.  This way they can better map the geospace environment.Probes P1 and P2 are called the 'outer probes' and P3, 4, and 5 are the 'inner probes'.  P3 and P4 share the same orbit.  The outer probes will detect the onset of the substorm, while the inner probes will monitor the Earthward plasma flows from the event.For more information on the GGCM model, visit the Community Coordinated Modeling Center and OpenGGCM. || ",
