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/ || ", "hits": 49 }, { "id": 5389, "url": "https://svs.gsfc.nasa.gov/5389/", "result_type": "Visualization", "release_date": "2024-11-14T00:00:00-05:00", "title": "Tracking methane with EMIT and AVIRIS-3", "description": "Methane plumes can now be detected using the airborne AVIRIS-3 spectrometer in addition to EMIT on the International Space Station.", "hits": 174 }, { "id": 5165, "url": "https://svs.gsfc.nasa.gov/5165/", "result_type": "Visualization", "release_date": "2024-01-05T00:00:00-05:00", "title": "STEREO - The Second Time Around...", "description": "In mid-August 2023, the still-operational STEREO-A (STEREO-B went offline in October 2014) passed Earth for the first time since its launch 17 years ago.

Dense stellar remnants called neutron stars create these bursts when they collide with other neutron stars or black holes. Short gamma-ray bursts, which last less than 2 seconds, are important sources for gravitational wave discoveries and multimessenger astronomy. BurstCube will use Earth’s magnetic field to orientate itself as it scans the sky. To do so, the mission team had to map the spacecraft’s own magnetic field using a special facility at NASA’s Wallops Flight Facility in Virginia. The magnetic calibration chamber generates a known magnetic field that cancels out Earth’s. The team's measurements of BurstCube’s field in the chamber will help figure out where the satellite is pointing once in space, so scientists can locate gamma-ray bursts and tell other observatories where to look. || ", "hits": 41 }, { "id": 31240, "url": "https://svs.gsfc.nasa.gov/31240/", "result_type": "Hyperwall Visual", "release_date": "2023-09-15T00:00:00-04:00", "title": "SWOT Captures the Yukon River in Alaska", "description": "SWOT view of the Yukon River, August 30, 2023 || PIA25780_print.jpg (1024x576) [341.9 KB] || PIA25780.png (3840x2160) [11.4 MB] || PIA25780_searchweb.png (320x180) [99.9 KB] || PIA25780_thm.png (80x40) [6.6 KB] || swot-captures-the-yukon-river-in-alaska.hwshow || ", "hits": 27 }, { "id": 14405, "url": "https://svs.gsfc.nasa.gov/14405/", "result_type": "Produced Video", "release_date": "2023-08-25T10:00:00-04:00", "title": "XRISM: Exploring the Hidden X-ray Cosmos", "description": "Watch this video to learn more about XRISM (X-ray Imaging and Spectroscopy Mission), a collaboration between JAXA (Japan Aerospace Exploration Agency) and NASA.Credit: NASA's Goddard Space Flight CenterMusic Credits: Universal Production MusicLights On by Hugh Robert Edwin Wilkinson Dreams by Jez Fox and Rohan JonesChanging Tide by Rob ManningWandering Imagination by Joel GoodmanIn Unison by Samuel Sim || YTframe_XRISM_Exploring_XrayCosmos.jpg (1280x720) [668.5 KB] || YTframe_XRISM_Exploring_XrayCosmos_searchweb.png (320x180) [100.3 KB] || YTframe_XRISM_Exploring_XrayCosmos_thm.png (80x40) [7.6 KB] || XRISM_Exploring_the_Hidden_Xray_Cosmos.en_US_FR.en_US.srt [7.8 KB] || XRISM_Exploring_the_Hidden_Xray_Cosmos.en_US_FR.en_US.vtt [7.4 KB] || XRISM_Exploring_the_Hidden_Xray_Cosmos.webm (3840x2160) [107.8 MB] || XRISM_Exploring_the_Hidden_Xray_Cosmos.mp4 (3840x2160) [3.4 GB] || XRISM_Exploring_the_Hidden_Xray_Cosmos.mov (3840x2160) [21.6 GB] || ", "hits": 234 }, { "id": 31220, "url": "https://svs.gsfc.nasa.gov/31220/", "result_type": "Hyperwall Visual", "release_date": "2023-03-27T00:00:00-04:00", "title": "SWOT Satellite's Sea Level 'First Light'", "description": "Sea Surface Height measurements in the Gulf Stream || PIA25772_print.jpg (1024x576) [97.4 KB] || PIA25772_searchweb.png (320x180) [46.9 KB] || PIA25772_thm.png (80x40) [11.2 KB] || PIA25772.tif (3840x2160) [2.7 MB] || swot-satellites-sea-level-first-light.hwshow || ", "hits": 29 }, { "id": 31221, "url": "https://svs.gsfc.nasa.gov/31221/", "result_type": "Hyperwall Visual", "release_date": "2023-03-27T00:00:00-04:00", "title": "SWOT Satellite's Land 'First Light'", "description": "Water features on New York's Long Island || PIA25774_print.jpg (1024x576) [183.9 KB] || PIA25774_searchweb.png (320x180) [58.8 KB] || PIA25774_thm.png (80x40) [11.1 KB] || PIA25774.tif (1920x1080) [6.0 MB] || -swot-satellites-land-first-light.hwshow [202 bytes] || ", "hits": 18 }, { "id": 31222, "url": "https://svs.gsfc.nasa.gov/31222/", "result_type": "Hyperwall Visual", "release_date": "2023-03-27T00:00:00-04:00", "title": "Sea Level Visualization of Gulf Stream", "description": "Sea surface height measurements of the Gulf Stream || PIA25773_print.jpg (1024x576) [90.5 KB] || PIA25773_searchweb.png (320x180) [40.1 KB] || PIA25773_thm.png (80x40) [11.6 KB] || PIA25773.tif (3840x2160) [1.8 MB] || sea-level-visualization-of-gulf-stream.hwshow [278 bytes] || ", "hits": 40 }, { "id": 40457, "url": "https://svs.gsfc.nasa.gov/gallery/cube-sats/", "result_type": "Gallery", "release_date": "2023-02-03T00:00:00-05:00", "title": "CubeSats", "description": "CubeSats are a class of nanosatellites that use a standard size and form factor.

The alignment of the telescope across all of Webb’s instruments can be seen in a series of images that captures the observatory’s full field of view. Featured in this video are engineering images demonstrating the sharp focus of each instrument. For this test, Webb pointed at part of the Large Magellanic Cloud, a small satellite galaxy of the Milky Way, providing a dense field of hundreds of thousands of stars across all the observatory’s sensors. The sizes and positions of the images shown depict the relative arrangement of each of Webb’s instruments in the telescope’s focal plane, each pointing at a slightly offset part of the sky relative to one another. Webb’s three imaging instruments are NIRCam (images shown here at a wavelength of 2 microns), NIRISS (image shown here at 1.5 microns), and MIRI (shown at 7.7 microns, a longer wavelength revealing emission from interstellar clouds as well as starlight). NIRSpec is a spectrograph rather than imager but can take images, such as the 1.1 micron image shown here, for calibrations and target acquisition. The dark regions visible in parts of the NIRSpec data are due to structures of its microshutter array, which has several hundred thousand controllable shutters that can be opened or shut to select which light is sent into the spectrograph. Lastly, Webb’s Fine Guidance Sensor tracks guide stars to point the observatory accurately and precisely; its two sensors are not generally used for scientific imaging but can take calibration images such as those shown here. This image data is used not just to assess image sharpness but also to precisely measure and calibrate subtle image distortions and alignments between the instrument sensors as part of Webb’s overall instrument calibration process. || ", "hits": 82 }, { "id": 14086, "url": "https://svs.gsfc.nasa.gov/14086/", "result_type": "Produced Video", "release_date": "2022-02-10T13:00:00-05:00", "title": "Landsat 9 Data Release", "description": "The data from Landsat 9 is available for anyone to download from the USGS data archive.

It takes 16 days for the swaths to overlap enough to image the whole Earth.Previous Landsat sensors swept back and forth across the swath like a whisk broom to collect data. The sensor looked at a calibration source at the end of every row, which means that measurements were consistent from orbit to orbit. But this sensor design requires fast-moving parts, which are more likely to break.—and which did on Landsat 7.In contrast, the instruments on Landsat 8 view across the entire swath at once, building strips of data like a pushbroom. This approach requires no moving parts and gives the sensor detectors greater dwell time. The pushbroom instrument is smaller and lighter than previous whisk broom instruments, but its calibration is much more complex given the large number of detectors.“It was a natural step to evolve to a pushbroom sensor. The technology was proven on other satellites, and we knew we could get better accuracy. The pushbroom has no moving parts. It is a newer and more reliable technology.” explains Terry Arvidson, senior project engineer.For more information on the future of Landsat instruments, read https://landsat.gsfc.nasa.gov/landsat-9/instruments/. || ", "hits": 367 }, { "id": 4002, "url": "https://svs.gsfc.nasa.gov/4002/", "result_type": "Visualization", "release_date": "2017-08-04T10:00:00-04:00", "title": "AR2665: The Lonely Sunspot of Solar Minimum", "description": "Full-disk view of sunspot group moving across the solar disk, AIA 171 ångstrom band. || July2017_AR2665_AIA171_stand.HD1080i.01000_print.jpg (1024x576) [53.8 KB] || AIA171 (1920x1080) [0 Item(s)] || July2017_AR2665_AIA171.HD1080i_p30.mp4 (1920x1080) [53.5 MB] || July2017_AR2665_AIA171.HD1080i_p30.webm (1920x1080) [8.5 MB] || July2017_AR2665_AIA171_2048p30.mp4 (2048x2048) [264.8 MB] || 171A-Frames (4096x4096) [0 Item(s)] || 171A-Time (4096x4096) [0 Item(s)] || July2017_AR2665_AIA171.HD1080i_p30.mp4.hwshow [200 bytes] || ", "hits": 39 }, { "id": 30884, "url": "https://svs.gsfc.nasa.gov/30884/", "result_type": "Hyperwall Visual", "release_date": "2017-06-23T00:00:00-04:00", "title": "CYGNSS First Light", "description": "The three maps on the right each show a single pass of the CYGNSS constellation, and the larger image on the left shows the full day's data combined into one image. || cygnss_1stlight_all_print.jpg (1024x574) [163.2 KB] || cygnss_1stlight_all.png (4104x2304) [27.1 MB] || cygnss_1stlight_all_searchweb.png (320x180) [60.9 KB] || cygnss_1stlight_all_thm.png (80x40) [5.6 KB] || ", "hits": 20 }, { "id": 12558, "url": "https://svs.gsfc.nasa.gov/12558/", "result_type": "Produced Video", "release_date": "2017-04-04T10:00:00-04:00", "title": "Goddard Helicopter Simulation of Venus Descent Imaging for Science", "description": "Venus Descent Imaging Proposal || RoadToVenus_Final_1080p.00132_print.jpg (1024x576) [64.2 KB] || RoadToVenus_Final_1080p.00132_searchweb.png (320x180) [55.4 KB] || RoadToVenus_Final_1080p.00132_web.png (320x180) [55.4 KB] || RoadToVenus_Final_1080p.00132_thm.png (80x40) [4.5 KB] || RoadToVenus_Final_1080p.mov (1920x1080) [2.5 GB] || RoadToVenus_Final_720p.mov (1280x720) [1.3 GB] || RoadToVenus_Final_720p.mp4 (1280x720) [257.0 MB] || RoadToVenus_Final_1080p.mp4 (1920x1080) [287.2 MB] || RoadToVenus_Final_1080p.webmhd.webm (1080x606) [41.0 MB] || RoadToVenus_Final.mov (2704x1520) [4.8 GB] || RoadToVenus.en_US.srt [5.0 KB] || RoadToVenus.en_US.vtt [5.0 KB] || ", "hits": 45 }, { "id": 12494, "url": "https://svs.gsfc.nasa.gov/12494/", "result_type": "Produced Video", "release_date": "2017-02-07T00:00:00-05:00", "title": "GPM Has Best Calibrated Microwave Imager in the World", "description": "This is an infographic describing how the GPM Microwave Imager works and maintains its high degree of calibration, as well as how it contributes to the precipitation rates produced by the mission. || GMI_Calibration_Infographic_10_Final.jpg (1275x5978) [2.9 MB] || GMI_thumbnail_searchweb.png (320x180) [39.4 KB] || GMI_thumbnail_thm.png (80x40) [4.2 KB] || ", "hits": 16 }, { "id": 12292, "url": "https://svs.gsfc.nasa.gov/12292/", "result_type": "Produced Video", "release_date": "2016-06-24T15:00:00-04:00", "title": "Solar Highlights of 2016/2017", "description": "A collection of solar highlights featuring:- NASA's Solar Dynamics Observatory (SDO)- NASA's Interface Region Imaging Spectrograph (IRIS) mission- ESA/NASA's Solar and Heliospheric Observatory (SOHO)- NASA's Solar TErrestrial RElations Observatory (STEREO) mission || ", "hits": 158 }, { "id": 4430, "url": "https://svs.gsfc.nasa.gov/4430/", "result_type": "Visualization", "release_date": "2016-03-03T00:00:00-05:00", "title": "JPSS Multi Mission Concept of Operations", "description": "The purpose of this visualization is to aid in establishing a shared understanding about key concepts, complexities, and unique features of a multi-mission JPSS.

Designed to research the interface region in more detail than has ever been done before, IRIS’s instrument is a combination of an ultraviolet telescope and a spectrograph. The telescope provides high-resolution images, capturing data on about 1 percent of the sun at a time. The images can resolve very fine features, as small as 150 miles across. While the telescope can look at only one wavelength of light at a time, the spectrograph collects information about many wavelengths of light at once. The instrument then splits the sun’s light into its various wavelengths and measures how much of any given wavelength is present.

While this obscures solar observations for a short while, it offers the chance for an interesting view of the shadow of the moon. The moon’s crisp horizon can be seen up against the sun, since the moon does not have an atmosphere. (At other times of the year, when Earth blocks SDO’s view, the Earth’s horizon looks fuzzy due to its atmosphere.) If one looks closely at such a crisp border, the features of the moon’s topography are visible, as is the case in this image from Oct. 7, 2010. This recently inspired two NASA visualizers to overlay a 3-dimensional model of the moon based on data from NASA’s Lunar Reconnaissance Orbiter into the shadow of the SDO image. Such a task is fairly tricky, as the visualizers — Scott Wiessinger who typically works with the SDO imagery and Ernie Wright who works with the LRO imagery — had to precisely match up data from the correct time and viewpoint for the two separate instruments. The end result is an awe-inspiring image of the sun and the moon. To start the process, the visualizers took the viewing position and time from the SDO image. This information was dropped into an LRO model that can produce the exact view of the moon from anywhere, at any time, by incorporating 6 billion individual measurements of the moon’s surface height from LRO’s Lunar Orbiter Laser Altimeter instrument. The model had to take many factors into consideration, including not only SDO’s distance and viewing angle, but also the moon’s rotation and constant motion. Wright used animation software to wrap the elevation and appearance map around a sphere to simulate the moon. The two images were put together and the overlay was exact. The mountains and valleys on the horizon of the LRO picture fit right into the shadows seen by SDO. In its own way, this served as a kind of calibration of data. It means that the SDO data on its position and time is highly accurate and that the LRO models, too, are able to accurately provide images of what’s happening at any given moment in time. And of course, the whole exercise provides for a beautiful picture. || ", "hits": 305 }, { "id": 11249, "url": "https://svs.gsfc.nasa.gov/11249/", "result_type": "Produced Video", "release_date": "2013-05-15T11:00:00-04:00", "title": "Landsat 8 Long Swath", "description": "After two months of on-orbit testing and calibration, Landsat 8 (previously called LDCM) fired its propulsion system on April 12, 2013, and ascended to its final orbit 438 miles (705 km) above Earth.

Salinity changes are linked to the cycling of freshwater around the planet and influence ocean circulation.The new map, which shows a tapestry of salinity patterns, demonstrates Aquarius' ability to detect large-scale salinity distribution features clearly and with sharp contrast. The map is a composite of the data since Aquarius became operational on Aug. 25. The mission was launched June 10 from Vandenberg Air Force Base in California. Aquarius/SAC-D is a collaboration between NASA and Argentina's space agency, Comision Nacional de Actividades Espaciales (CONAE).To produce the map, Aquarius scientists compared the early data with ocean surface salinity reference data. Although the early data contain some uncertainties, and months of additional calibration and validation work remain, scientists are impressed by the data's quality.The map shows several well-known ocean salinity features such as higher salinity in the subtropics; higher average salinity in the Atlantic Ocean compared to the Pacific and Indian Oceans; and lower salinity in rainy belts near the equator, in the northernmost Pacific Ocean and elsewhere. These features are related to large-scale patterns of rainfall and evaporation over the ocean, river outflow and ocean circulation. Aquarius will monitor how these features change and study their link to climate and weather variations.Other important regional features are evident, including a sharp contrast between the arid, high-salinity Arabian Sea west of the Indian subcontinent, and the low-salinity Bay of Bengal to the east, which is dominated by the Ganges River and south Asia monsoon rains. The data also show important smaller details, such as a larger-than-expected extent of low-salinity water associated with outflow from the Amazon River.Aquarius was built by NASA's Jet Propulsion Laboratory (JPL) in Pasadena, Calif., and the Goddard Space Flight Center in Greenbelt, Md., for NASA's Earth Systems Science Pathfinder Program.

Webb will peer through dusty clouds to see stars forming planetary systems, connecting the Milky Way to our own Solar System. Webb's instruments are designed to work primarily in the infrared range of the electromagnetic spectrum, with some capability in the visible range.\n\nWebb has a large primary mirror, 6.5 meters (21.3 feet) in diameter and a sunshield the size of a tennis court. Both the mirror and sunshade are too large to fit onto the Ariane 5 rocket fully open, so both were folded which meant they needed to be unfolded in space. \n\nWebb is currently in its operational orbit about 1.5 million km (1 million miles) from the Earth at a location known as Lagrange Point 2 (L2).\n\nThe James Webb Space Telescope was named after the NASA Administrator who crafted the Apollo program, and who was a staunch supporter of space science.", "hits": 911 } ] }
