            "description": "This stereoscopic visualization shows a simple model of the Earth's magnetic field. The magnetic field partially shields the Earth from harmful charged particles emanating from the sun. The field is stretched back away from Sun by solar particle and radiation pressures.The geomagnetic field is generated (and regenerated) as the conducting fluid of the Earth's mantle and core, driven by convection of heat from deeper in the interior, induces an electromotive force (EMF) with the existing magnetic field.  This process is very similar to the way an electric generator generates a voltage.  That voltage then drives an induced current in the conducting fluid, which also produces a magnetic field.  This feedback mechanism helps maintain the field, continuously converting the thermal energy in the Earth into magnetic field energy.The magnetic field line data used in this visualization is from a simplified static model. More complex models deform the magnetic field over time as the Earth rotates and experiences solar pressures. Many of the field lines (particulary near the back, away from the Sun) should eventually connect (north and south poles), but the 3d model used in this visualization does not extend far enough to see this.The day/night terminator is aligned with the Sun and is therefore aligned with the magnetic field too. This visualization is based on a previous monoscopic visualizaton that included magnetic field line data. || ",

            "description": "The oceans are mostly composed of warm salty water near the surface over cold, less salty water in the ocean depths. These two regions don't mix except in certain special areas. The ocean currents, the movement of the ocean in the surface layer, are driven primarily by the wind. In certain areas near the polar oceans, the colder surface water also gets saltier due to evaporation or sea ice formation. In these regions, the surface water becomes dense enough to sink to the ocean depths. This pumping of surface water into the deep ocean forces the deep water to move horizontally until it can find an area on the world where it can rise back to the surface and close the current loop. This usually occurs in the equatorial ocean, mostly in the Pacific and Indian Oceans. This very large, slow current is called the thermohaline circulation because it is caused by temperature and salinity (haline) variations.This animation shows one of the major regions where this pumping occurs, the North Atlantic Ocean around Greenland, Iceland, and the North Sea. The surface ocean current brings new water to this region from the South Atlantic via the Gulf Stream and the water returns to the South Atlantic via the North Atlantic Deep Water current. The continual influx of warm water into the North Atlantic polar ocean keeps the regions around Iceland and southern Greenland generally free of sea ice year round.The animation also shows another feature of the global ocean circulation: the Antarctic Circumpolar Current. The region around latitude 60 south is the the only part of the Earth where the ocean can flow all the way around the world with no obstruction by land. As a result, both the surface and deep waters flow from west to east around Antarctica. This circumpolar motion links the world's oceans and allows the deep water circulation from the Atlantic to rise in the Indian and Pacific Oceans, thereby closing the surface circulation with the northward flow in the Atlantic.The color on the world's ocean's at the beginning of this animation represents surface water density, with dark regions being most dense and light regions being least dense (see the animation Sea Surface Temperature, Salinity and Density). The depths of the oceans are highly exaggerated to better illustrate the differences between the surface flows and deep water flows. The actual flows in this model are based on current theories of the thermohaline circulation rather than actual data. The thermohaline circulation is a very slow moving current that can be difficult to distinguish from general ocean circulation. Therefore, it is difficult to measure or simulate.This is a stereoscopic version of the original visualziation. || ",

At this time the spacecraft were about 3.7 degrees apart. These images show the Sun in extreme ultraviolet light at a wavelength of 171 angstroms, highlighting parts of the Sun's atmosphere (the corona) at about one million degrees C. Note the bright active regions near the Sun's equator and the dark \"coronal holes\" at the north and south poles. These are features of the Sun's magnetic field. Coronal holes are areas where the magnetic field opens out to allow material to flow out into the solar system, while active regions are made up of strong, closed fields which bottle up hot plasma (ionized gas) close to the surface. This image was taken near the minimum in solar activity, so there are few active regions.Closeup View: Image sequences taken April 8-9, 2007 by the EUVI telescopes in the SECCHI imaging suites on the two STEREO spacecraft (STEREO-B, left eye; STEREO-A, right eye). At this time the spacecraft were about 3.7 degrees apart. Here we see a close up of solar magnetic active regions, flickering as they rotate out of sight around the sun. These are areas where the Sun's strong magnetic field bottles up million degree C plasma (ionized gas) low in the corona (the Sun's outer atmosphere). These images are taken at a wavelength of 171 angstroms (0.00000171 cm) in the extreme ultraviolet.Note for Large Displays: These movies are produced using images from STEREO where the angle between the spacecraft is getting larger than the optimum angle for stereo separation. While they work well on small displays, large-screens and projection systems can introduce significant distortions in the stereo effect which the audience may find uncomfortable. When doing large-screen projection, you may need to adjust the left-right image alignment for optimum viewing. However, this does not guarantee a distortion-free result. || ",

At this time, Hurricane Danielle was a powerful Category 4 hurricane on the Saffir-Simpson scale with sustained winds of 115 knots (132 mph). An area of deep convective towers (shown in red) is prominently visible in the center of the storm. These tall towers are the key to Danielle's intensification. They are associated with the strong thunderstorms responsible for the areas of intense rain. These storms within a storm are releasing vast amounts of heat into the core of Danielle. This heating, known as latent heating, is what is driving the storm's circulation and intensification. This animation shows infrared data from TRMM's Visible Infrared Scanner (VIRS) sensor above a thinner swath from TRMM's Precipitation Radar (PR). TRMM reveals that Danielle now has a well-formed eye surrounded by sharply curved rainbands—all signs of mature storm with an intense circulation. TRMM also reveals that there are very powerful thunderstorms in Danielle's eye wall dropping extreme amounts of rain. || ",

            "description": "The Greenland ice sheet has been the focus of attention recently because of increasing melt in response to regional climate change. Several different remote sensing data products have been used to study surface and near-surface melt characteristics of the Greenland ice sheet for the 2007 melt season when record melt extent and runoff occurred. Here, MODIS daily land surface temperature and a special diurnal melt product, derived from QuikSCAT scatterometer data, measure the evolution of melt on the ice sheet. Although these daily products are sensitive to different geophysical features, they show excellent correspondence when surface melt is present. This animation displays these two geophysical data products of the Greenland ice sheet side-by-side, showing MODIS data on the left side and QuikSCAT data on the right. The 2007 melt season is shown twice. In the first sequence, MODIS surface temperature is compared with several categories of QuikSCAT melt between March 15th and October 13th, 2010. During this sequence, active melt detected by QuikSCAT is shown in light blue, reduced melt is medium blue, and completed melt is dark blue. For the MODIS, surface temperature is shown with the color scale — red indicates a surface temperature greater than -1 degree Celsius. As MODIS shows warmer surface temperature as the melt season progresses, QuikSCAT consistently identifies the corresponding melt.In the second sequence, the MODIS and QuikSCAT melted regions of the ice sheet were accumulated during the melt season. QuikSCAT captures melt earlier, and then melt is detected by MODIS shortly afterward at a higher spatial resolution. The final result (frame) shows the seasonal melt extent which was consistently delineated by both sensors. The cross-verification of these independent measurements, by two different instruments on different satellites, provides a higher confidence level in the melt observations, reducing the uncertainty in climate assessment of Greenland melt.This visualization is a stereoscopic version of animation entry:  #3738: 2007 Greenland Melt Season Study.

At the time the data was collected, Katrina was a Category 5 hurricane, the most destructive and deadly. The cloud cover data was taken by TRMM's Visible and Infrared Scanner (VIRS), with additional data from the GOES spacecraft. The rain structure data was taken by TRMM's Tropical Microwave Imager (TMI). This view looks underneath the storm's clouds to reveal the underlying rain structure. This stereoscopic still image was created from a previous visualization and is intended for viewing through a special NASA Earth Science Viewfinder available through NASA Headquarters.

LRO launches from Cape Canaveral, then flies around the Earth and on to the moon. Time speeds up during the journey to the moon, then slows again as LRO approaches the moon. LRO begins orbiting the moon and, through a series of several \"burns\", moves in closer to its desired orbit. LRO's initial orbit plane around the moon is parallel to the direction of the moon's travel.This visualization was created before launch using simulated ephemeris data. The ephemeris data driving this visualization was based on a simulated night time launch on 11/24/2008; but, the actual launch may happen during the daytime.

            "description": "The SeaWiFS instrument aboard the SeaStar satellite has been collecting ocean data since 1997. By monitoring the color of reflected light via satellite, scientists can determine how successfully plant life is photosynthesizing. A measurement of photosynthesis is essentially a measurement of successful growth, and growth means successful use of ambient carbon.This animation represents nearly a decade's worth of data taken by the SeaWiFS instrument, showing the abundance of life in the sea. This time period repeats twice during the animation. Dark blue represents warmer areas where there is little life due to lack of nutrients, and greens and reds represent cooler nutrient-rich areas. The nutrient-rich areas include coastal regions where cold water rises from the sea floor bringing nutrients along and areas at the mouths of rivers where the rivers have brought nutrients into the ocean from the land. The nutrient-rich waters contribute to some of the oxygen-poor pockets of the seas called dead zones.This visualization is a stereoscopic version of animation entry:  #3420:SeaWiFS Biosphere Global Rotation from 1997 to 2006 || ",

            "title": "How LRO Will Find Safe Landing Sites on the Moon - Stereoscopic Version",
            "description": "The first attempt to land humans on the moon - Apollo 11 - was a triumph that almost ended in disaster. At just 400 feet from the lunar surface, with only about a minute's worth of fuel remaining, astronauts Neil Armstrong and Edwin 'Buzz' Aldrin saw that their ship's computer was taking them directly into a crater the size of a football field, strewn with SUV-sized boulders. They quickly took control from the computer, flew over the crater and touched down in a smoother area beyond, cutting the engine with just 30 seconds of fuel left.  In general, good landing sites need to be level and free from large boulders that could damage or tip the spacecraft as it attempts to land. And it's up to the Lunar Reconaissance Orbiter (LRO) mission to make those landings as safe as possible.  Astronauts will want to avoid places with steep slopes that could tip the spacecraft, so LRO includes a laser ranging system that will build an elevation map to show the contours of the polar surface. The instrument, called the Lunar Orbiter Laser Altimeter (LOLA ), records the time it takes for a laser pulse to travel from the spacecraft to the lunar surface and back to calculate the height of the lunar terrain. After a year in orbit aboard LRO, LOLA will have created an elevation map of the polar regions that is accurate to within a half-meter (20 inches) vertically and 50 meters (about 160 feet) horizontally.  LRO will also use data from another instrument that measures temperatures to double-check the safe zone map. Temperatures change more rapidly in areas with loose materials (lots of rocks). By analyzing how quickly temperatures change in potential landing zones, planners using the instrument, named Diviner, can rule out areas that appear smooth but actually are likely to be rocky.  LRO also carries a pair of eagle-eyed cameras, called the Narrow Angle Cameras (NACs) which together can take images that reveal details as small as a half-meter (almost 20 inches) over swaths 10 kilometers (about 6.2 miles) wide. As LRO orbits over the poles, the moon rotates beneath the spacecraft, and the NACs will gradually build up a detailed picture of the region. It will be used to identify safe landing zones free of large boulders and craters, allowing astronauts to avoid surprises like Apollo 11.  LRO is being assembled and managed by NASA Goddard, and is scheduled to be launched in early 2009. NASA plans to have astronauts back on the moon by 2020. As astronauts close in on a new landing site late in the next decade, they can thank NASA Goddard's small robot scout for showing the safest approach. This visualization is a modified stereoscopic version of: #3533: How LRO Will Find Safe Landing Sites on the Moon The modifications applied in the production of the stereoscopic visualization include: extension of the time range of the animation, color adjustments, scale bar and text overlay treatment.The crater depicted in this visualization is ficticious and only intended for illustrative purposes. The visualization begins with the reveal of a digital elevation map showing sample lunar topography illustrating the kind of data that LRO's LOLA instrument will collect. From this topographic data level surface areas can be derived as the first step to determining safe landing sites. Next, an example temperature map of the lunar surface is revealed to show the sort of data Diviner will collect. Changes in surface temperature will help determine small rock hazards, since they retain and release heat at a different rate than the surrounding regolith. Large rock hazards can be found with LROC's surface imagery. Finally, removing rock hazard areas from level surface areas reveals potential safe landing sites for future lunar missions.In this page the visualization content is offered in various modes to accomodate different types of stereoscopic viewing, such as: Left and Right Eye separate, and Left and Right Eye side-by-side combined on the same frame. || ",

            "description": "This is a longer coronal loops tour combining components of the two previous versions (Animation IDs 3286 and 3287). The solar model is constructed from magnetogram data collected by SOHO/MDI. Because we do not see the full solar surface at any one time, the magnetograms collected over the course of a solar rotation are processed through a time-evolving solar surface model which provides a snapshot of the surface at a fixed time. The resulting magnetogram is then processed through the Potential Field Source Surface (PFSS) model which constructs the magnetic field above the solar surface. The magnetic field around the Sun is then analyzed for field lines, which creates the loop structures we see in the model. Hot plasma tends to flow along the magnetic field lines, creating the coronal loops. These loops are only visible at the higher temperatures corresponding to ultraviolet light, in this case, 195 angstroms, one of the filter wavelengths of SOHO/EIT. For this version, we color the coronal loops green for ready comparison to the EIT 195 angstrom imagery using the EIT standard color table. || ",
