The TRACERS mission will help scientists understand an explosive process called magnetic reconnection and its effects in Earth’s atmosphere. Magnetic reconnection occurs when magnetic fields and particles from the Sun interact with Earth’s magnetic field. By understanding this process, scientists will be able to better understand and prepare for impacts of solar activity on Earth, such as auroras and disruptions to telecommunications.Below are clips of TRACERS’ instrument design, build, and testing at the University of Iowa in Iowa City, Iowa.Learn more about the mission: https://science.nasa.gov/mission/tracers/ || ",

            "description": "Remember that Y2K thing a few years ago? Where everyone was afraid the world was going to end because computer programmers saved space by putting dates as… 77 for 1977. 85 for 1985. Or 90 for 1990. But then it became clear that when the year 2000 finally rolled around all of the computers would think it was actually 00. Or the year 1900.Well, it turns out Hubble has something similar, only Hubble’s clock restarts every 6,213 days, 18 hours, 48 minutes, and 31.875 seconds. Or roughly every 17 years for those of you who like counting.That’s because Hubble’s computers have a different way of tracking time than we have here on the ground. You’d think it would be as simple as synching our ground clocks with Hubble’s personal timepiece, but you’d be surprised. For more information, visit https://nasa.gov/hubble.

            "description": "Could the first tropical storm of the Atlantic hurricane season break the 10-year “hurricane drought” record?It has been a decade since the last major hurricane, Category 3 or higher, has made landfall in the United States. This is the longest period of time for the United States to avoid a major hurricane since reliable records began in 1850. According to a NASA study, a 10-year gap comes along only every 270 years. The National Hurricane Center calls any Category 3 or more intense hurricane a “major” storm. It should be noted that hurricanes making landfall as less than Category 3 can still cause extreme damage, with heavy rains and coastal storm surges. Such was the case with Hurricane Sandy in 2012.Timothy Hall, a research scientist who studies hurricanes at NASA’s Goddard Institute for Space Studies, New York and colleague Kelly Hereid, who works for ACE Tempest Re, a reinsurance firm based in Connecticut, ran a statistical hurricane model based on a record of Atlantic tropical cyclones from 1950 to 2012 and sea surface temperature data. The researchers ran 1,000 computer simulations of the period from 1950-2012 – in effect simulating 63,000 separate Atlantic hurricane seasons. They also found that there is approximately a 40% chance that a major hurricane will make landfall in the United States every year. These visualizations show hurricane tracks from 1980 through 2015. Green tracks are storms that did not make landfall in the U.S.; yellow tracks are storms that made landfall but were not Category 3 or higher; and red tracks are Category 3 or higher hurricanes that did make landfall.Research: The frequency and duration of U.S. hurricane droughtsJournal: Geophysical Research Letters, May 5, 2015 || ",

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. || ",

            "description": "On March 15, 2013, at 2:54 a.m. EDT, the sun erupted with an Earth-directed coronal mass ejection (CME), a solar phenomenon that can send billions of tons of solar particles into space and can reach Earth one to three days later and affect electronic systems in satellites and on the ground. Experimental NASA research models, based on observations from the Solar Terrestrial Relations Observatory (STEREO) and ESA/NASA's Solar and Heliospheric Observatory, show that the CME left the sun at speeds of around 900 miles per second, which is a fairly fast speed for CMEs. Historically, CMEs at this speed have caused mild to moderate effects at Earth.Update: On March 17, 2013, at 1:28 a.m. EDT, the coronal mass ejection (CME) from March 15 passed by NASA's Advanced Composition Explorer (ACE) as it approached Earth. Upon interacting with the giant magnetic bubble surrounding Earth, the magnetosphere, the CME caused a kind of solar storm known as a geomagnetic storm. The storm initially caused a mild storm rated on NOAA's geomagnetic storm scales as a G2 on a scale from G1 to G5, and subsequently subsided to a G1. In the past, storms of this strength have caused auroras near the poles but have not disrupted electrical systems on Earth or interfered with GPS or satellite-based communications systems. || ",

Space weather includes any and all conditions and events on the sun, in the solar wind, in near-Earth space and in our upper atmosphere that can affect space-borne and ground-based technological systems and through these, human life and endeavor. Heliophysics is the science of space weather.\r\n\r\nThis gallery organizes satellite footage, animations, visualizations, and edited videos produced at the Goddard Space Flight Center.  Visualizations are different from pure animations because they are data-driven.  They present a way of \"seeing\" the data.  In the case of orbit visualizations, they are based on actual orbit information.  Most of the animations and visualizations are available as frames and all the recent ones are HD quality.  All videos are available in several formats and qualities including Apple ProRes for broadcast quality.  Unless specifically marked otherwise, all these materials are public domain and free to use.  For more infomation about NASA's media use guidelines see this page.\r\n\r\nThe content is organized in two ways.  Under \"Facets of Space Weather\" you will find our visuals grouped by the subject they address.  Under \"NASA Spacecraft\" you will find our visuals grouped by the satellite they were collected by, or that they refer to.  This group also contains animations of the spacecraft themselves.\r\nFor breaking news solar events, go to this gallery.For frequently-asked-question interviews with NASA scientists, go here.",

            "description": "The sun regularly spews forth bursts of particles and magnetic fields known as a coronal mass ejection, or, CME. A CME starts small in solar terms—just a few hundred times the size of the Earth—but it grows and changes as it travels toward the edges of the solar system. Scientists have been observing these events with satellites for decades, but tracking the details of an ejection's growth from original seed to complex structure near Earth has been more challenging. In fact, scientists recently used three NASA spacecraft—STEREO-A, WIND and ACE—to create the first visual record of a CME's path from the sun to the Earth. The orbiting instruments captured the CME's birth on Dec. 12, 2008 at the sun's surface, its exponential growth and its ultimate engulfing of the Earth about three days later. These ejections are common but large solar events can alter our magnetic atmosphere to such a degree that communications signals from GPS or telecom satellites are temporarily degraded beyond recognition. This visualization allowed scientists to watch how features early in the CME ultimately create the form seen closer to Earth, with a bright leading edge and trailing evacuated cavity. || ",

            "description": "We start from a position 'behind' the Earth, looking towards the Sun. From this position we see the orbit of the Moon as well as three of the heliospheric 'sentinels' (see \"Sentinels of the Heliosphere\"), ACE, SOHO, and Wind patrolling along 'halo orbits' (Wikipedia) around the Sun-Earth Lagrange Point, L1.The CME (orange isosurface) erupts, heading towards the Earth. The density enhancement of the CME is visible in slice of data in the Earth's orbit plane which provides a better sense of when the CME actually reaches the Earth.As the particle density enhancement from the CME strikes the Earth, we see the Earth's magnetosphere respond, with the outer, high density surface (red), 'blown away'. This surface location corresponds roughly to the location of the bow shock. The bow shock has not been eliminated, only some of its particles have been depleted, to be carried off in the CME and solar wind. As the densest material of the CME passes (orange surface), plasma from the CME continues to flow by the Earth, stretching the magnetosphere into a long, thin structure behind the Earth.The magnetosphere slowly recovers from the 'impact', and regions that can confine higher particle densities reform - the red surfaces return. But not for long as the rarefaction behind the CME reaches the Earth. This lower density region provides fewer particles to repopulate the magnetosphere and make it easier for particles confined in the magnetosphere to 'leak' out into the solar wind.For the BATS-R-US model, the isosurface colors are: red=20 AMUs per cubic centimeter, yellow=10.0 AMUs per cubic centimeter, light blue=1.0 AMUs per cubic centimeter, and blue=0.1 AMUs per cubic centimeter. An AMU corresponds to about the mass of a hydrogen atom, the dominant component of the solar wind.This visualization is part of a series of visualizations on space weather modeling. || ",

These natural events can have significant effects on Earth and space-based technologies that can cause anything from inconveniences (such as minor communications and power disruptions) to high-impact events that have significant political and economic implications (outages of large sections of the electrical power grid and other support infrastructure).\n\nTo better meet these challenges, mathematical models of the heliospheric and geospace environment are under development to better forecast these solar energetic events and their impacts on Earth.\n\nThe visualizations here illustrate two models generated by the CCMC for modeling space weather events.  The CCMC hosts many different computational models.  Both models were generated based on a single coronal mass ejection (CME) event in December 2006.\n\nEnlil: The Enlil model is a time-dependent 3-D magnetohydrodynamic (MHD, Wikipedia) model of the heliosphere.  In these simulations, the model covers a torus-like region around the Sun, with the inner edge at about 0.1 astronomical units (AU) (about 22 solar radii) from the Sun and the outer edge extends beyond the orbit of Mars (1.5 AU).  The model extends to 60 degrees above and below the solar equator.  The model propagates the changes in particle flows and magnetic fields.\n\nBATS-R-US:  BATS-R-US is also an MHD model of plasma from the solar wind moving through the Earth's magnetic dipole field.  The model is initialized using measurements of the solar wind density, velocity, temperature, and magnetic field from satellites orbiting L1, such as ACE.",
