The process of reconnection involves the explosive release of energy when the magnetic fields around Earth connect and disconnect. These fields help protect Earth from harmful effects of solar storms and cosmic rays. Magnetic reconnection also occurs throughout the universe and can accelerate particles up to nearly the speed of light.By studying reconnection in this local, natural laboratory, MMS helps us understand reconnection elsewhere as well, such as in the atmosphere of the Sun and other stars, in the vicinity of black holes and neutron stars, and at the boundary between our solar system’s heliosphere and interstellar space.MMS consists of four identical observatories that will provide the first three-dimensional view of magnetic reconnection. The four MMS observatories will fly through reconnection regions in a tight formation in well under a second, so key sensors on each spacecraft are designed to measure the space environment at rates faster than any previous mission.For additional visuals regarding the MMS mission and science, please see our MMS Pre-launch Gallery.Briefing participants include:Jeff Newmark, interim director, Heliophysics DivisionNASA Headquarters, WashingtonJim Burch, principal investigator, MMS instrument suite science teamSouthwest Research Institute, San AntonioRoy Torbert, MMS FIELDS investigation leadUniversity of New Hampshire, Durham, New HampshireCraig Pollock, lead co-investigator, MMS Fast Plasma Investigation Goddard Space Flight Center, Greenbelt, MarylandPaul Cassak, associate professorWest Virginia University, Morgantown || ", "hits": 22 }, { "id": 11522, "url": "https://svs.gsfc.nasa.gov/11522/", "result_type": "Produced Video", "release_date": "2014-05-07T12:00:00-04:00", "title": "The Best Observed X-class Flare", "description": "On March 29, 2014 the sun released an X-class flare.

To have a record of such an intense flare from so many observatories is unprecedented. Such research can help scientists better understand what catalyst sets off these large explosions on the sun.

In the case of astronomy, those tools enable us to analyze the light in many different wavelengths and many different ways.Many different instruments are observing the Sun almost continuously, both from space and on the surface of the Earth. On March 29, 2014, the Dunn Solar Telescope at Sacramento Peak, New Mexico was observing a solar active region and requested other observatories to watch as well. As a result of this coordination, the region was being observed by a large number of different instruments, ground and space-based, when it subsequently erupted with an X-class flare. This visualization presents various combinations of the datasets collected during this effort. The color text represents the dominant color of the dataset in the imagery.Solar Dynamics Observatory (SDO): HMI (617.1nm). This data represents the Sun is visible light similar to how we see it from the ground.Solar Dynamics Observatory (SDO): AIA (17.1nm). Solar ultraviolet emission, which can only be seen from space, reveals plasma flowing, and escaping, along magnetic fields.IRIS Slit-Jaw Imager: 140.0nm. This high-resolution imager also contains a slit (the dark vertical line in the center of the field) which directs the light to an ultraviolet spectrometer which is used to extract even more information about the light. The imager slews back-and-forth across the region, providing spectra over a larger area of the Sun.Hinode/X-ray Telescope: x-ray band. Indicates very hot plasma.RHESSI: 50-100 keV. High-energy gamma-ray emission. Emission from these locations represent the very highest energy photons from the flare event.Dunn Solar Telescope: G-band filter. This filter, showing much of the solar surface (photosphere) in visible light, provides a detailed view of the sunspots and convection cells. The view moves because the instrument was repointed several times during the observation.Dunn Solar Telescope: IBIS ( Hydrogen alpha, 656.3nm; Calcium 854.2 nm; Iron 630.15nm). This is the small rectangular view within the Dunn Solar Telescope G-band view. This instrument can tune the wavelength during the observation, which provides views of the solar atmosphere at different depths. || ", "hits": 46 }, { "id": 11199, "url": "https://svs.gsfc.nasa.gov/11199/", "result_type": "Produced Video", "release_date": "2013-07-15T10:00:00-04:00", "title": "X Marks the Spot: SDO Sees Reconnection", "description": "Two NASA spacecraft have provided the most comprehensive movie ever of a mysterious process at the heart of all explosions on the sun: magnetic reconnection. Magnetic reconnection happens when magnetic field lines come together, break apart, and then exchange partners, snapping into new positions and releasing a jolt of magnetic energy. This process lies at the heart of giant explosions on the sun such as solar flares and coronal mass ejections, which can fling radiation and particles across the solar system. Magnetic field lines, themselves, are invisible, but the sun's charged plasma particles course along their length. Space telescopes can see that material appearing as bright lines looping and arcing through the sun’s atmosphere, and so map out the presence of magnetic field lines. Looking at a series of images from the Solar Dynamics Observatory (SDO), scientists saw two bundles of field lines move toward each other, meet briefly to form what appeared to be an “X” and then shoot apart with one set of lines and its attendant particles leaping into space and one set falling back down onto the sun. To confirm what they were seeing, the scientists turned to a second NASA spacecraft, the Reuven Ramaty High Energy Solar Spectroscopic Imager (RHESSI). RHESSI collects spectrograms, a kind of data that can show where exceptionally hot material is present in any given event on the sun. RHESSI showed hot pockets of solar material forming above and below the reconnection point, an established signature of such an event. By combining the SDO and RHESSI data, the scientists were able to describe the process of what they were seeing, largely confirming previous models and theories, while revealing new, three-dimensional aspects of the process. || ", "hits": 82 }, { "id": 11286, "url": "https://svs.gsfc.nasa.gov/11286/", "result_type": "Produced Video", "release_date": "2013-06-04T12:00:00-04:00", "title": "IRIS L-14 Media Briefing", "description": "Lying just above the sun's surface is an enigmatic region of the solar atmosphere called the interface region. A relatively thin region, just 3,000 to 6,000 miles thick, it pulses with movement: zones of different temperature and density are scattered throughout, while energy and heat course through the solar material. Understanding how the energy travels through this region – energy that helps heat the upper layer of the atmosphere, the corona, to temperatures of 1,000,000 kelvins, some thousand times hotter than the sun’s surface itself – is the goal of NASA's Interface Region Imaging Spectrograph, or IRIS, scheduled to launch on June 26, 2013 from California's Vandenberg Air Force Base. Scientists wish to understand the interface region in exquisite detail, since energy flowing through this region has an effect on so many aspects of near-Earth space. For one thing, despite the intense amount of energy deposited into the interface region, only a fraction leaksthrough, but this fraction drives the solar wind, the constant stream of particles that flows out to fill the entire solar system. The interface region is also the source of most of the sun's ultraviolet emission, which impacts both the near-Earth space environment and Earth's climate. IRIS's capabilities are uniquely tailored to unravel the interface region by providing both high-resolution images and a kind of data known as spectra, which can see many wavelengths at once. For its high-resolution images, IRIS will capture data on about one percent of the sun at a time. While these are relatively small snapshots, IRIS will be able to see very fine features, as small as 150 miles across. || ", "hits": 55 }, { "id": 40115, "url": "https://svs.gsfc.nasa.gov/gallery/space-weather/", "result_type": "Gallery", "release_date": "2011-12-01T00:00:00-05:00", "title": "Space Weather", "description": "The term \"space weather\" was coined not long ago to describe the dynamic conditions in the Earth's outer space environment, in the same way that \"weather\" and \"climate\" refer to conditions in Earth's lower atmosphere.
