"description": "In Spring of 2016, Operation IceBridge conducted its eight spring Arctic survey of polar ice over the course of five weeks. Six research flights studying sea ice were based in Thule, Greenland, while ten that focused on land ice flew out of Kangerlussuaq in southern Greenland.For the survey, the crew utilized National Oceanic and Atmospheric Administration’s P-3 Orion Hurricane Hunter plane. NASA's Wallops Flight Facility in Virginia provided the laser altimeter and one of the infrared cameras on the P-3. IceBridge's three radar instruments came from the Center for Remote Sensing of Ice Sheets at the University of Kansas, while NASA's Ames Research Center at Moffett Field, California, provided the Digital Mapping System, and the University of Colorado loaned the second infrared camera.During this campaign the IceBridge aircraft flew under the path of Sentinel-3A, a recently launched ESA satellite that carries a radar altimeter that gauges sea ice thickness. Scientists will compare the Sentinel-3A measurements to the data IceBridge collected over the same spots with its radar and laser altimeters. This comparison will help validate and refine Sentinel-3A’s data gathering. || ",

"description": "The Airborne Topographic Mapper (ATM), developed at NASA Wallops Flight Facility in Wallops Island, Va., is a scanning laser altimeter that measures changes in ice surface elevation.

By combining this timing data with detailed information about the aircraft’s position and attitude from GPS and inertial navigation systems, ATM can measure topography to an accuracy of as small as four inches. By flying ATM over the same swath of ground previously covered by ICESat, researchers can maintain a record of changes.In addition, the precise data from ATM’s navigation system can be fed to pilot displays in the cockpit or even electronically sent to the automatic pilot system, keeping the aircraft aligned with the planned survey track. This keeps the aircraft along the planned ATM survey swath and also benefits the other IceBridge instruments by minimizing aircraft roll and horizontal acceleration.The ATM has been participating in NASA's Operation IceBridge since 2009. || ",

This keeps the aircraft along the planned ATM survey swath and also benefits the other IceBridge instruments by minimizing aircraft roll and horizontal acceleration. || ",

"description": "The Global Ecosystem Dynamics Investigation (GEDI) uses laser pulses to give a view of the 3D structure of the Earth. GEDI’s precise measurements of the height and vertical structure of forest canopy, along with the surface elevation, will greatly advance our ability to characterize important carbon and water cycling processes, biodiversity, and habitat. The mission is led by the University of Maryland, College Park, and the instrument was built and tested at NASA's Goddard Space Flight Center.GEDI observes nearly all tropical and temperate forests using a self-contained laser altimeter on the International Space Station. GEDI has the highest resolution and densest sampling of any lidar ever put in orbit. This has required a number of innovative technologies to be developed at NASA Goddard.GEDI has three lasers that produce 8 parallel tracks of observations. Each laser fires 242 times per second and illuminates a 25-meter footprint on the surface over which 3D structure is measured. Each footprint is separated by 60 meters along the track, with an across-track distance of about 600 m between each of the 8 tracks. GEDI is expected to produce about 10 billion cloud-free observations during its nominal 24-month mission length.With these observations, GEDI will provide answers to how deforestation has contributed to atmospheric CO2 concentrations, how much carbon forests will absorb in the future, and how habitat degradation will affect global biodiversity. This data is of immense value for forest and water resource management, carbon cycle science, and weather prediction.For more information about GEDI: https://gedi.umd.edu || ",

"description": "Next month, NASA will launch into space the most advanced laser instrument of its kind, beginning a mission to measure – in unprecedented detail – changes in the heights of Earth’s polar ice.NASA’s Ice, Cloud and land Elevation Satellite-2 (ICESat-2) will measure the average annual elevation change of land ice covering Greenland and Antarctica to within the width of a pencil, capturing 60,000 measurements every second.“ICESat-2’s new observational technologies will advance our knowledge of how the ice sheets of Greenland and Antarctica contribute to sea level rise while also helping us understand the connection of sea ice loss to the global system,” said Thomas Wagner, cryosphere program scientist in NASA’s Science Mission Directorate.ICESat-2 will extend and improve upon NASA's 15-year record of monitoring the change in polar ice heights, which started in 2003 with the first ICESat mission and continued in 2009 with NASA’s Operation IceBridge, an airborne research campaign that monitors the accelerating rate of change.ICESat-2 represents a major technological leap in our ability to measure changes in ice height. Its Advanced Topographic Laser Altimeter System (ATLAS) measures height by timing how long it takes individual light photons to travel from the spacecraft to Earth and back.NASA will host a media teleconference at 1 p.m. EDT Wednesday, Aug. 22, to discuss the upcoming launch of the Ice, Cloud and land Elevation Satellite (ICESat-2), which will fly NASA's most advanced laser altimeter to measure Earth’s changing ice. The teleconference will stream live on NASA's website.ICESat-2 is scheduled to launch Sept. 15 from Vandenberg Air Force Base.The briefing participants are: • Tom Wagner, cryosphere program scientist in the Science Mission Directorate (SMD) at NASA Headquarters • Richard Slonaker, ICESat-2 program executive in SMD • Doug McLennan, ICESat-2 project manager at NASA’s Goddard Space Flight Center • Donya Douglas-Bradshaw, Advanced Topographic Laser Altimeter System (ATLAS) instrument project manager at Goddard • Tom Neumann, ICESat-2 deputy project scientist at GoddardFor more information:Media AdvisoryICESat-2 Video Resources || ",

"description": "Pho, a plucky bright green photon of light, must travel from a NASA spacecraft down to Earth and back again to help complete a crucial science mission in this educational short film. The animation was created and produced by media art students from the Savannah College of Art in Design (SCAD) in Georgia, in collaboration with NASA’s Ice, Cloud and Land Elevation Satellite-2 (ICESat-2) mission. Their goal was to communicate the science and engineering of the mission, slated for launch in 2018. ICESat-2, managed by NASA Goddard in Greenbelt, Maryland, will measure the height of a changing Earth, one laser pulse at a time, 10,000 laser pulses a second. ICESat-2 will carry a photon-counting laser altimeter that will allow scientists to measure the elevation of ice sheets, glaciers, sea ice and more - all in unprecedented detail. The workings of this laser helped inspire students to create the character of Pho and plot his adventure. Our planet's frozen and icy areas, called the cryosphere, are a key focus of NASA's Earth science research. ICESat-2 will help scientists investigate why, and how much, our cryosphere is changing in a warming climate. The satellite will also measure heights across Earth's temperate and tropical regions, and take stock of the vegetation in forests worldwide.

"title": "Orientale Impact Basin for the Cover of Science",
"description": "This print-resolution still image was created for the cover of the October 28, 2016 issue of Science. It features a free-air gravity map of the Orientale impact basin based on data returned by the Gravity Recovery and Interior Laboratory (GRAIL) mission.Orientale is about 930 kilometers wide and lies on the western limb of the Moon as viewed from Earth. It's the Moon's youngest and best-preserved large impact basin, formed about 3.8 billion years ago at the end of the conjectured Late Heavy Bombardment. A paper in Science by Maria Zuber et al. uses the GRAIL data to shed new light on the basin's geology, while a second paper by Brandon Johnson et al. describes a computer simulation of the basin's formation constrained by that data.The shaded relief in this image is not a photograph. It's a very accurate computer rendering based on a digital model of the terrain. The model is derived from a digital elevation map called SLDEM2015. This map combines data from the laser altimeter (LOLA) on NASA's Lunar Reconnaissance Orbiter (LRO) with stereo imagery from the Terrain Camera on the Japan Space Agency's SELENE spacecraft.The angle of the virtual Sun was chosen to throw Orientale's terrain into high relief — it's just after sunrise at Orientale, about a day past full Moon. The camera is on the western terminator (day/night line) looking north.The colorful part is the gravity anomaly based on measurements by GRAIL. Red indicates areas of higher gravity, or excess mass, and blue indicates lower gravity or areas of mass deficits. The GRAIL data reveals the structure of the basin beneath the surface. The red in the center of the basin, for example, shows that the crust is particularly thin there, and that denser mantle material is closer to the surface. || ",

"description": "This gallery was created for Earth Science Week 2015 and beyond. It includes a quick start guide for educators and first-hand stories (blogs) for learners of all ages by NASA visualizers, scientists and educators. We hope that your understanding and use of NASA's visualizations will only increase as your appreciation grows for the beauty of the science they portray, and the communicative power they hold. Read all the blogs and find educational resources for all ages at: the Earth Science Week 2015 page.Four turboprop engines roar to life under the autumnal Alaskan sun, and we begin to taxi to the main runway of Eielson Air Force Base. After extensive pre-flight configurations, our science payload is primed for our eight-hour mission. Without delay, the engines’ roar becomes a howl as we hurtle down the nearly three-mile stretch of runway until that near-weightless moment we become airborne. Our mission into the clouds of the arctic is underway.Clouds are important drivers of Earth’s climate by regulating the amount of sunlight that is absorbed at the ground versus what is reflected back into space. You’ve probably experienced this firsthand when sitting outside on a hot and sunny summer day when a fluffy cumulus cloud crosses the sky between you and the sun. The respite that you feel from the heat of the sun’s rays means that that energy is no longer reaching you at the surface. At the lower latitudes where most of us live, these thick, stratiform and cumuliform clouds have a cooling effect because the white cloud reflects the sun’s energy back to space instead of being absorbed by the dark brown soil, green trees and plants, or the blue ocean waters. The story is much more complicated at the high latitudes where the frozen ice surface is also very bright white and reflective. Under these conditions, clouds can actually have a net warming effect because they reflect a similar or smaller amount of the incoming sunlight, but also trap more of the outgoing heat radiation and keep it close to the surface (like a blanket.)The exact balance between heating and cooling depends on the cloud properties - droplet number and size - and where the clouds are located in the atmosphere (high or low altitude as well as overlying dark water or bright ice.) Unraveling these effects is important for understanding how the Earth’s radiation balance and climate exist now and how they are likely to change in the future.Differentiating the impacts of low-level clouds versus Arctic sea ice on sunlight from space is hard, because to a passive satellite sensor orbiting many hundreds of kilometers above the Earth’s surface, both the ice and cloud look very similar. To best visualize this system, we must go to the Arctic with scientific research aircraft to measure the cloud properties just below, above, and within the clouds themselves. This was precisely the motivation behind the NASA Arctic Radiation – IceBridge Sea and Ice Experiment (ARISE), which was conducted in the Alaskan Arctic from September-October, 2014.ARISE carried out 14 science flights aboard the NASA Wallops Flight Facility C-130 Hercules aircraft, which was outfitted with a comprehensive suite of scientific instrumentation including a laser altimeter for measuring the sea ice surface properties, in situ cloud probes, and a sun photometer and two radiometers (SSFR, BBR) for measuring the surface, aerosol, and cloud radiative properties. An example 8-hour flight track is shown for the September 7th science flight in the Google Map below. The aircraft was based at Eielson Air Force Base near Fairbanks, AK, and began each flight by transiting approximately 2 hours north to the vicinity of the ice edge in the Beaufort Sea. On the 7th, the aircraft flew a series of parallel, horizontal legs to cover a single satellite grid box of the overflying NASA Clouds and the Earth's Radiant Energy System (CERES) satellite. These measurements help CERES scientists to understand how small-scale variability in ice and cloud extent and properties affect their satellite-based retrievals. Google map showing the flight track of the NASA C-130 aircraft during a research flight conducted on 7 September 2014 north of the Alaskan coast. Before wrapping up the research flight on the 7th and beginning our 2-hour transit back to Fairbanks, we descended into the low-level clouds to measure their microphysical properties with the in situ cloud probes. The video below shows what it’s like to measure an Arctic cloud from inside it! The left side of the video shows the real-time data time series from our research instruments that we are continuously monitoring in flight. The top-right imagery is from the forward-facing camera in the C-130 cockpit. The bottom-right imagery is from the downward-facing, nadir camera mounted on the bottom of the aircraft. || ",

"title": "Supermoon 2014",
"description": "On August 10, 2014, the Moon will be full at the same time that it is closest to Earth for the year. This coincidence is sometimes called a supermoon.The Moon's orbit is very slightly elliptical and therefore somewhat 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 2014 occurs on August 10 at around 17:49 Universal Time, when the Moon will be 356,896 kilometers (221,765 miles) away. As it happens, this is only a few minutes before the time of peak full Moon at 18:10 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, on average, while 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.Recently, a much broader definition of \"supermoon\" has taken hold. It includes both Full and New Moons, and perigee merely needs to be \"close enough,\" generally within a couple of days. By this definition, there are six or seven supermoons every year, half of which can't be observed. Not so super!The actual shape of the Moon's orbit is another source of confusion. The orbit is often depicted as an almost cigar-shaped ellipse, but this is a misleading exaggeration. If you were to draw the orbit on a sheet of paper, its deviation from a perfect circle would be less than the thickness of your pencil point. The 50,000 kilometer (30,000 mile) difference between perigee and apogee is almost entirely due to the orbit being off-center. The difference between the semimajor and semiminor axes is less than 1000 kilometers (600 miles).The animation begins in mid-July, showing that perigee and Full Moon miss each other by about a day. It then shows apogee on July 28, when the Moon is almost 32 Earth diameters away. It ends on August 10, 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.) || ",

"title": "A New Look at the Apollo 11 Landing Site",
"description": "Apollo 11 landed on the Moon on July 20th, 1969, a little after 4:00 in the afternoon Eastern Daylight Time. The Lunar Module, nicknamed Eagle and flown by Neil Armstrong and Edwin \"Buzz\" Aldrin, touched down near the southern rim of the Sea of Tranquility, one of the large, dark basins that contribute to the Man in the Moon visible from Earth. Armstrong and Aldrin spent about two hours outside the LM setting up experiments and collecting samples. At one point, Armstrong ventured east of the LM to examine a small crater, dubbed Little West, that he'd flown over just before landing.The trails of disturbed regolith created by the astronauts' boots are still clearly visible in photographs of the landing site taken by the Lunar Reconnaissance Orbiter (LRO) narrow-angle camera (LROC) more than four decades later.LROC imagery makes it possible to visit the landing site in a whole new way by flying around a three-dimensional model of the site. LROC scientists created the digital elevation model using a stereo pair of images. Each image in the pair shows the site from a slightly different angle, allowing sophisticated software to infer the shape of the terrain, similar to the way that left and right eye views are combined in the brain to produce the perception of depth.The animator draped an LROC photograph over the terrain model. He also added a 3D model of the LM descent stage—the real LM in the photograph looks oddly flat when viewed at an oblique angle.Although the area around the site is relatively flat by lunar standards, West Crater (the big brother of the crater visited by Armstrong) appears in dramatic relief near the eastern edge of the terrain model. Ejecta from West comprises the boulders that Armstrong had to avoid as he searched for a safe landing site.Apollo 11 was the first of six increasingly ambitious crewed lunar landings. The exploration of the lunar surface by the Apollo astronauts, when combined with the wealth of remote sensing data now being returned by LRO, continues to inform our understanding of our nearest neighbor in space. || ",

"title": "Earthrise: The 45th Anniversary",
"description": "In December of 1968, the crew of Apollo 8 became the first people to leave our home planet and travel to another body in space. But as crew members Frank Borman, James Lovell, and William Anders all later recalled, the most important thing they discovered was Earth.Using photo mosaics and elevation data from Lunar Reconnaissance Orbiter (LRO), this video commemorates the 45th anniversary of Apollo 8's historic flight by recreating the moment when the crew first saw and photographed the Earth rising from behind the Moon. Narrator Andrew Chaikin, author of A Man on the Moon, sets the scene for a three-minute visualization of the view from both inside and outside the spacecraft accompanied by the onboard audio of the astronauts.The visualization draws on numerous historical sources, including the actual cloud pattern on Earth from the ESSA-7 satellite and dozens of photographs taken by Apollo 8, and it reveals new, historically significant information about the Earthrise photographs. It has not been widely known, for example, that the spacecraft was rolling when the photos were taken, and that it was this roll that brought the Earth into view. The visualization establishes the precise timing of the roll and, for the first time ever, identifies which window each photograph was taken from.The key to the new work is a set of vertical stereo photographs taken by a camera mounted in the Command Module's rendezvous window and pointing straight down onto the lunar surface. It automatically photographed the surface every 20 seconds. By registering each photograph to a model of the terrain based on LRO data, the orientation of the spacecraft can be precisely determined.Andrew Chaikin's article Who Took the Legendary Earthrise Photo From Apollo 8? appeared in the January, 2018 issue of Smithsonian magazine. It includes the story of the making of this visualization.A Google Hangout discussion of this visualization between Ernie Wright (creator of the visualization), Andrew Chaikin, John Keller (LRO project scientist), and Aries Keck (NASA media specialist) was held on December 20, 2013. A replay of that hangout is available here.Ernie Wright presented a talk about the making of this animation at the 2014 SIGGRAPH Conference in Vancouver. He also wrote a NASA Wavelength blog entry about Earthrise that includes links to educator resources related to LRO. || ",

"description": "Just as we do on Earth, the Solar Dynamics Observatory satellite periodically crosses the Moon's shadow and experiences a solar eclipse. During the eclipse witnessed by SDO on October 7, 2010, the southern hemisphere of the Moon was silhouetted against the solar disk, revealing some especially prominent mountain peaks near the Moon's south pole. By using elevation data from Lunar Reconnaissance Orbiter to visualize the Moon from SDO's point of view, it's possible to identify these peaks. Although all of these are well-known features, all but one of them have no official names. The following list corresponds to the labels in the animation, from left to right.In his 1954 sketch of the lunar south pole, astronomer Ewen Whitaker labeled this feature \"M3.\" It's a mountain about halfway between the craters Cabeus and Drygalski, at 83.2°S 68°W.Whitaker's \"M1,\" a mountain on the northern rim of Cabeus, 83.4°S 33°W.A mountain on the southern rim of Malapert crater, about halfway between the centers of Malapert and Haworth. Whitaker labels this Malapert Alpha.

"title": "The Moon and the Sun: Two NASA Missions Join Their Images",
"description": "Two or three times a year, NASA’s Solar Dynamics Observatory observes the moon traveling across the sun, blocking its view. 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. || ",

"title": "LAMP Observes GRAIL Impact",
"description": "The Gravity Recovery and Interior Laboratory (GRAIL) mission comprised a pair of satellites that together measured the gravity field of the Moon. GRAIL ended its mission with a planned impact into the side of a lunar mountain on December 17, 2012. Lunar Reconnaissance Orbiter (LRO) maneuvered into an orbit that would allow it to observe the impact. One of LRO's instruments, the Lyman-Alpha Mapping Project (LAMP), looked for the chemical signatures of a number of elements, including hydrogen and mercury, in the dust plume kicked up by the impact.This animation shows the relative positions of GRAIL and LRO at the time of the impact, as well as the view from LAMP as it scanned for the dust plume. The LAMP sensor is a 6.0° x 0.3° slit that was positioned to look over the limb of the Moon, so that it would be pointed into the tenuous dust plume with only the sky in the background. This observation was possible, in part, because GRAIL impacted on the night side of the Moon, where there was no concern that LAMP's sensitive detector could be blinded by sunlit terrain. From Earth, the Moon was a waxing crescent at the time of the impact. || ",

"title": "LRO Peers into Permanent Shadows",
"description": "The Moon's permanently shadowed regions, or PSRs, are places on the Moon that haven't seen the Sun in millions, or even billions, of years. The Earth's tilted axis allows sunlight to fall everywhere on its surface, even at the poles, for at least part of the year. But the Moon's tilt relative to the Sun is only 1.6°, not enough to get sunlight into some deep craters near the lunar north and south poles. PSRs are therefore some of the coldest, darkest places in the solar system.Because of that, PSRs are expected to be excellent traps for volatiles, chemicals that would normally vaporize and escape into space, and this includes water. Lunar Reconnaissance Orbiter (LRO) includes several instruments designed to peer into the PSR darkness and measure temperature, reflectivity, and neutron absorption, all of which are clues to what chemicals might be hiding there. This animation shows where the PSRs are and in what ways LRO can see inside them. || ",

"title": "GRAIL Free-Air Gravity Map for the Cover of Science",
"description": "These print-resolution stills were created for the cover of the February 8, 2013 issue of Science. They show the free-air gravity map developed by the Gravity Recovery and Interior Laboratory (GRAIL) mission.If the Moon were a perfectly smooth sphere of uniform density, the gravity map would be a single, featureless color, indicating that the force of gravity at a given elevation was the same everywhere. But like other rocky bodies in the solar system, including Earth, the Moon has both a bumpy surface and a lumpy interior. Spacecraft in orbit around the Moon experience slight variations in gravity caused by both of these irregularities.The free-air gravity map shows deviations from the mean, the gravity that a cueball Moon would have. The deviations are measured in milliGals, a unit of acceleration. On the map, dark purple is at the low end of the range, at around -400 mGals, and red is at the high end near +400 mGals. Yellow denotes the mean.These views show a part of the Moon's surface that's never visible from Earth. They are centered on lunar coordinates 29°N 142°E. The large, multi-ringed impact feature near the center is Mare Moscoviense. The crater Mendeleev is south of this. The digital elevation model for the terrain is from the Lunar Reconnaissance Orbiter laser altimeter (LOLA). Merely for plausibility, the sun angle and starry background are accurate for specific dates (December 21, 2012, 0:00 UT and January 8, 2013, 14:00 UT, respectively). || ",

"description": "As part of the first demonstration of laser communication with a satellite at the moon, scientists with NASA's Lunar Reconnaissance Orbiter (LRO) beamed an image of the Mona Lisa to the spacecraft from Earth.The iconic image traveled nearly 240,000 miles in digital form from the Next Generation Satellite Laser Ranging (NGSLR) Station at NASA's Goddard Space Flight Center in Greenbelt, MD, to the Lunar Orbiter Laser Altimeter (LOLA) instrument on the spacecraft. By transmitting the image piggyback on laser pulses that are routinely sent to track LOLA's position, the team achieved simultaneous laser communication and tracking.To learn more about how it happened, watch the video below! || ",

"title": "GRAIL Primary Mission Gravity Maps (AGU 2012)",
"description": "The Gravity Recovery and Interior Laboratory (GRAIL) mission comprises a pair of satellites launched in September, 2011 and placed in orbit around the Moon in January, 2012. The two satellites, named Ebb and Flow, used radio signals to precisely measure their separation as they flew in formation, one following the other in the same nearly circular polar orbit. These measurements allowed mission scientists to build up an accurate and detailed gravity map of the Moon.If the Moon were a perfectly smooth sphere of uniform density, the gravity experienced by the spacecraft would be exactly the same everywhere. But like other rocky bodies in the solar system, including the Earth, the Moon has both a bumpy surface and a lumpy interior. As the spacecraft fly in their orbits, they experience slight variations in gravity caused by both of these irregularities, variations which show up as small changes in the separation of the two spacecraft.The free-air gravity map shows these variations directly. (Free-air is a historical term; there is, of course, no air on the Moon.) The Bouguer gravity map subtracts the effect of the bumpy surface to show the lumpiness underneath. The elevation maps from the laser altimeter on Lunar Reconnaissance Orbiter (LRO) were used to create a model of what the gravity would be if the Moon were bumpy but not lumpy. This model was then subtracted from the free-air map to produce the Bouguer map. (Note: The Bouguer map shown here was filtered to emphasize smaller features; harmonic degrees 1 to 6 were excluded.)The crustal thickness map is inferred from the Bouguer map: If the density of the crust is assumed to be uniform, then the gravity anomalies visible in the Bouguer gravity map can be explained by variations in the thickness of the crust. Highs in gravity indicate places where the denser mantle is closer to the surface, and hence where the crust is thinner.While aiding navigation for future lunar missions, GRAIL's gravity measurements reveal information about the internal structure of the Moon, improving our understanding of the origin and development of not just the Moon, but also the Earth and the rest of the inner solar system. || ",

"title": "RXTE Views X-ray Pulsar Occulted by the Moon",
"description": "On Oct. 13, 2010, NASA's Rossi X-ray Timing Explorer (RXTE), a satellite in low-Earth orbit, observed a bursting X-ray pulsar as it was eclipsed by the Moon. 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. || ",
