Additionally, IMAP will support real-time observations of the solar wind and energetic particles, which can produce hazardous conditions in the space environment near Earth. The IMAP spacecraft will be located at Lagrange Point 1, or L1. Lagrange points are positions in space where objects sent there tend to stay put. At L1, which is around 1 million miles from Earth towards the Sun, the gravitational pull of the Sun and Earth are balanced, allowing spacecraft to reduce fuel consumption needed to remain in position. At L1, IMAP will have a clear view of the heliosphere and will also be positioned to provide advanced warning of incoming solar storms headed to Earth.

By imaging the Sun’s corona and the solar wind together, scientists hope to better understand the entire inner heliosphere – Sun, solar wind, and Earth – as a single connected system.Three of the PUNCH satellites will carry a Wide Field Imager (WFI), and the fourth will carry the Narrow Field Imager (NFI).The Narrow Field Imager (NFI)The Narrow Field Image (NFI) is a coronagraph, a type of device that blocks out the bright light from the Sun to better see details in the Sun's outer atmosphere, or corona. The coronagraph will have a similar field of view as the SOHO (Solar and Heliospheric Observatory) Large Angle and Spectrometric Coronagraph (LASCO) C3 field, from 6 to 32 solar radii on the sky, and it will view the corona in both polarized and unpolarized light.Wide Field Imager (WFI)The Wide Field Imager (WFI) is a heliospheric imager, a device that provides views from 18 to 180 solar radii (45 degrees) away from the Sun in the sky. Heliospheric imagers use an artificial “horizon” and deep baffles to view the very faint outermost portion of the solar corona and the solar wind itself. The instrument reduces direct sunlight by over 16 orders of magnitude, which is like the ratio between the mass of a human and the mass of a cold virus. The wide-field imaging optics are based on the design of the famous Nagler eyepieces, which are known among observational astronomers for their clarity, low distortion, wide field, and achromatic focus.

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 || ", "hits": 86 }, { "id": 4436, "url": "https://svs.gsfc.nasa.gov/4436/", "result_type": "Visualization", "release_date": "2016-03-21T12:30:00-04:00", "title": "GMM-3 Mars Gravity Map", "description": "Scientists have used small fluctuations in the orbits of three NASA spacecraft to map the gravity field of Mars.Watch this video on the NASA Goddard YouTube channel.Complete transcript available.This video is also available on our YouTube channel. || MarsGravityMapYouTube.png (1920x1080) [7.9 MB] || MarsGravityMapYouTube.jpg (1920x1080) [706.6 KB] || APPLE_TV_G2016-003_Mars_Gravity_Map_MASTER_appletv.m4v (1280x720) [51.0 MB] || WEBM_G2016-003_Mars_Gravity_Map_MASTER.webm (960x540) [43.4 MB] || APPLE_TV_G2016-003_Mars_Gravity_Map_MASTER_appletv_appletv_subtitles.m4v (1280x720) [15.5 MB] || LARGE_MP4_G2016-003_Mars_Gravity_Map_MASTER_large.mp4 (1920x1080) [109.0 MB] || NASA_TV_G2016-003_Mars_Gravity_Map_MASTER.mpeg (1280x720) [362.0 MB] || G2016-003_Mars_Gravity_Map_MASTER_GoogOut.en_US.srt [1.8 KB] || G2016-003_Mars_Gravity_Map_MASTER_GoogOut.en_US.vtt [1.9 KB] || G2016-003_Mars_Gravity_Map_MASTER.mov (1920x1080) [2.9 GB] || ", "hits": 127 }, { "id": 4404, "url": "https://svs.gsfc.nasa.gov/4404/", "result_type": "Visualization", "release_date": "2015-12-10T12:00:00-05:00", "title": "Moon Phase and Libration, 2016", "description": " || Click on the image to download a high-resolution version with labels for craters near the terminator.The data in the table for the entire year can be downloaded as a JSON file or as a text file. || moon.0001.jpg (730x730) [74.4 KB] || comp.0001.tif (1920x1080) [2.5 MB] || ", "hits": 650 }, { "id": 4405, "url": "https://svs.gsfc.nasa.gov/4405/", "result_type": "Visualization", "release_date": "2015-12-10T12:00:00-05:00", "title": "Moon Phase and Libration, 2016 South Up", "description": " || Click on the image to download a high-resolution version with labels for craters near the terminator.The data in the table for the entire year can be downloaded as a JSON file or as a text file. || moon.0001.jpg (730x730) [74.4 KB] || comp.0001.tif (3840x2160) [7.1 MB] || ", "hits": 79 }, { "id": 4356, "url": "https://svs.gsfc.nasa.gov/4356/", "result_type": "Visualization", "release_date": "2015-09-15T00:00:00-04:00", "title": "LRO and the September 27-28, 2015 Lunar Eclipse: Telescopic View", "description": "On September 28, 2015 (the night of September 27), the Moon enters the Earth's shadow, creating a total lunar eclipse.

A solar eclipse happens when the Moon’s shadow falls on the Earth, while a lunar eclipse happens when the Earth’s shadow falls on the Moon.Eclipses can only happen at New and Full Moon, when the Earth, Moon, and Sun are all in a straight line. But they don’t happen every New and Full Moon, because the Moon’s orbit is tilted by about 5 degrees. As the Earth and Moon travel around the Sun, the tilt of the Moon’s orbit changes direction relative to the Sun.This is analogous to the way the tilt of the Earth causes seasons. Just like winter and summer happen every six months, eclipses tend to occur on a roughly six-month cycle.Unlike most eclipse shadow diagrams, the first three animations here don’t greatly exaggerate the scale of the Earth and Moon. They are only 2x their true scale. The view is exactly perpendicular to the Earth-Sun line. The angle of the Moon’s orbital tilt and the “tapering” of the shadows are both accurate.

Luna 3 was the third spacecraft to reach the Moon and the first to send back pictures of the Moon's far side. The pictures were noisy and indistinct, but because the Moon always presents the same face to the Earth, they offered views of a part of the Moon that had never been seen before.The far side of the Moon is surprisingly different. The most striking difference evident in the Luna 3 pictures is the absence of the large, dark seas of cooled lava, called maria, that cover a substantial fraction of the Earth-facing near side. The far side is instead densely peppered with impact craters of every size and age.Fifty years later, in June of 2009, Lunar Reconnaissance Orbiter (LRO) launched from Kennedy Space Center in Florida. Using LRO's global elevation maps and photographic mosaics, both of which are of unprecedented quality and detail, it's possible to accurately recreate the view captured in the pictures from Luna 3. As seen here, Luna 3 was directly over 12°N 120°E at a distance of 61,700 kilometers above the surface, and its camera was banked 17.5° clockwise from vertical relative to the Moon's north pole.The thicker blue longitude line at 90°E, along the left side of the LRO image, marks the boundary between the near and far sides of the Moon. To the left of that line are the familiar maria Crisium (the circular spot near the 9 o'clock position), Marginis, Smythii (both east of Crisium), Humboldtianum (in the north), Australe (near the south pole), and the eastern edge of Fecunditatis. The bright spot near the center of the disk is a complex of unnamed craters bordered by King, Langemak, Gregory, and Abul Wafa craters. The brightness is enhanced because it's near the subsolar point. The dark, sharp-edged shield shape in the southern hemisphere, with the white dot in the middle, is Tsiolkovskiy crater and its central peak. The dark spot to the southeast of Tsiolkovskiy is the crater Jules Verne. The mare in the northeast is Moscoviense. || ", "hits": 2149 }, { "id": 3880, "url": "https://svs.gsfc.nasa.gov/3880/", "result_type": "Visualization", "release_date": "2013-10-01T00:00:00-04:00", "title": "Earth Observing Spacecraft Fleet shot for Dynamic Earth Dome Show", "description": "This visualization shows the orbits of NASA's fleet of Earth observing spacecraft.

This coincidence is sometimes called a supermoon.The Moon's orbit is slightly elliptical and therefore a little off-center relative to the Earth. Each month, the Moon passes through points in its orbit called perigee and apogee, the closest and farthest points from the Earth for that month. Some perigees are a little closer than others. The closest perigee for 2013 occurs on June 23 at around 11:18 Universal Time, when the Moon will be 356,991 kilometers (221,824 miles) away. As it happens, this is only a few minutes before the time of peak full Moon at 11:32 UT, when the Moon's ecliptic longitude differs from the Sun's by exactly 180 degrees.How often does this happen? The period between perigees, called the anomalistic month, is 27.55 days. The time between full Moons, called the synodic month, is 29.53 days. These two periods sync up every 413 days, or 1.13 years. 15 anomalistic months are about as long as 14 synodic months. So that's how often the pattern repeats.The animation begins in May, showing that perigee and full Moon miss each other by about a day. It then shows apogee on June 9, when the Moon is almost 32 Earth diameters away. It ends on June 23, the day of the supermoon, when the distance to the Moon is 28 Earth diameters. The Moon graphic in the upper left shows the change in the Moon's apparent size as it moves closer and farther in its orbit. (The relative sizes of the Earth and Moon in the main orbit graphic are exaggerated by a factor of 15 to make them more easily visible.)By another coincidence, the supermoon occurs just two days after the northern summer solstice, when the Sun reaches its highest point in the northern hemisphere sky.

This provided scientists with an unusual opportunity to calculate the precise position of the pulsar by timing its disappearance and reappearance at the edge of the Moon's disk.The story began a few days earlier, on Oct. 10, when the European Space Agency's INTEGRAL satellite detected a transient X-ray source in the direction of Terzan 5, a globular star cluster about 25,000 light-years away toward the constellation Sagittarius. This was the start of an extradordinary series of outbursts that ended Nov. 19. The object, dubbed IGR J17480-2446, is classed as a low-mass X-ray binary system, where a neutron star orbits a star much like the Sun and draws a stream of matter from it. As only the second bright X-ray source to be found in Terzan 5, scientists shortened the name of the system to T5X2. As shown in this animation, ingress (the moment when the pulsar disappeared) occurred on the Moon's eastern limb just above the equator. Egress, 8 minutes 32 seconds later, was near the south pole on the western limb. The timing of ingress and egress depended delicately on the shape of the terrain. In other words, it mattered whether the pulsar passed behind a mountain or a valley. So the calculation relied on the detailed topography measured by both JAXA's Kaguya and NASA's Lunar Reconnaissance Orbiter.The animation faithfully reproduces the angle of the Sun, the position of RXTE, the position and orientation of the Moon as seen from the satellite, the Moon's topography, and the starry background. RXTE's position was derived from the Goddard Flight Dynamics Facility ephemeris for day 6129 of the satellite's orbit, while the Sun and Moon positions came from JPL's DE421 solar system ephemeris. All of the positions and the viewing direction were transformed into Moon body-fixed coordinates, so that in the animation software, the Moon remained stationary at the origin, while the camera moved and pointed appropriately. The Moon, the stars, the pulsar, and the clock were all rendered separately and layered together. || ", "hits": 117 }, { "id": 3551, "url": "https://svs.gsfc.nasa.gov/3551/", "result_type": "Visualization", "release_date": "2012-09-01T00:00:00-04:00", "title": "The Coronal Mass Ejection strikes the Earth!", "description": "This visualization is the sequel to animation ID 3867.The CME we saw before continues to expand from the Sun, and its outer boundary is approaching the Earth.

As historian Robert Poole noted, this lack of preparation meant that the sight of Earth came with the force of a revelation, not just for the astronauts but for everyone on the ground.

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 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 flows in this visualization are based on current theories of the thermohaline circulation rather than actual data or computational model runs. 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 and simulate.This visualization was produced for the Science On a Sphere production \"Loop\". It is intended to be over-layed on a world map background. Below are 3 sets of 4 sequences. The first set of 4 sequences are all composited over a world map background with a limited number of frames that make them loopable (with a very slight jump at the point where the looping happens). This is primarily provided for real-time displays such as hyperwall systems. The 4 sequences are: all depth layers combined, shallow depths, middle depths, and deep depths.The second set is the same as the first set except that the layers are not composited over the background and instead include and alpha channel. The third layer is actually the frames that were used in the film \"Loop\" and consist of a large number of continuous, seamless frames. Each sequence is as before, all layers, shallow, middle, and deep layers all with alpha channels.The depth layers nominally correspond to the following ranges below sea level: shallow (0m - 600m), middle (1875m - 2500m), and deep (3000m - 4000m). These depths do vary with bathymetry. So, in areas where the sea floor is not very deep, these depths are scaled so that the flows do not interesct the sea floor or each other. || ", "hits": 124 }, { "id": 10846, "url": "https://svs.gsfc.nasa.gov/10846/", "result_type": "Produced Video", "release_date": "2011-10-18T12:00:00-04:00", "title": "Coronal Mass Ejections (CMEs) Blast Their Way Through the Solar System", "description": "A coronal mass ejection erupts from the Sun and propagates out through the Solar System. Along the way it is detected by the spacecraft at Jupiter and Saturn. Eventually it is detected by the two Voyager spacecraft beyond the orbit of Pluto.

Sea ice goes through this shrink-and-swell rhythm every year, but since consistent satellite observations began in 1979, both the annual minimum at the end of summer and the annual maximum at the end of winter continue to decline in area and thickness.Arctic sea ice extent on Sept. 9 was 4.33 million square kilometers (1.67 million square miles), placing 2011 as the second lowest minimum ice extent on record. Ice extent was 2.43 million square kilometers (938,000 square miles) below the 1979 to 2000 average.Below two versions of the AMSR-E visualization is a video featuring NASA Cryosphere Program Manager Tom Wagner, who shares his insights on the 2011 minimum. || ", "hits": 43 } ] }
