"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": "Oceanus Procellarum, or the Ocean of Storms, is the largest of the dark maria visible to the naked eye on the near side of the Moon. Its relatively flat surface of basaltic lava covers most of the northwest quadrant of the Moon's disk.The leading explanation of Procellarum's origin is that it is a large, ancient impact basin. But the authors of a paper in the October 2, 2014 edition of the journal Nature suggest instead that this region is the result of the way the lunar crust cooled billions of years ago.The red in the image shown here is part of a pattern of gravity anomalies revealed by data from the Gravity Recovery and Interior Laboratory (GRAIL) mission. Jeffrey Andrews-Hanna and his coathors interpret this rectangular feature as a remnant of the plumbing system that moved magma to the surface of the Moon's near side, flooding low-lying areas with lava.The rectangular shape differs from the circular shape expected for an impact basin. It more closely resembles the pattern of cracks that form in materials subjected to thermal stress. In fact, the paper compares the shape of the Procellarum gravity anomaly with a feature spanning the south pole of Enceladus, the ice-covered moon of Saturn. || ",

"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. || ",

"description": "This print-resolution still image was created for the cover of the May 28, 2014 issue of Geophysical Research Letters. It features a free-air gravity map of the Moon's southern latitudes developed by S. Goossens et al. from data returned 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 gravity that a cueball Moon would have. The deviations are measured in milliGals, a unit of acceleration. On the map, 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.The map shown here extends from the south pole of the Moon up to 50°S and reveals the gravity for that region in even finer detail than the global gravity maps published previously. The image illustrates the very good correlation between the gravity map and topographic features such as peaks and craters, as well as the mass concentration lying beneath the large Schrödinger basin in the center of the frame. The terrain in the image is based on Lunar Reconnaissance Orbiter (LRO) altimeter and camera data. || ",

"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. || ",

This image, which shows the dramatic landscape within the crater Copernicus was often referred to as the \"picture of the century\" by many people at the time of its original public release in 1966.This image was taken by the Lunar Orbiter 2 spacecraft at 7:05 p.m. EST on 24 November 1966 from an altitude of 28.4 miles above the lunar surface, 150 miles due south of Copernicus. At the time this image was originally released most views of the lunar surface involved looking straight down. Little, if any, sense of the true elevation of lunar surface features was usually available. This photo changed that perception by showing the Moon to be a world with tremendous topography - some of it Earth-like, much of it decidedly un-earth-like. || ",

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. The second animation shows the relationship between the Sun and the Earth at both the summer and winter solstice. || ",

"title": "Lunar Transit from Solar Dynamics Observatory (2010)",
"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. It's also known as Mons Malapert or Malapert Peak. 85.8°S 0°E.Labeled Leibnitz Beta by Whitaker and now officially named Mons Mouton, this is part of the highlands adjacent to the northern rim of Nobile crater. 84°S 37°E. Part of the Leibnitz mountain range first identified by Johann Schröter in the late 1700s, unrelated to Leibnitz Crater on the lunar far side.A mountain near Amundsen crater, on the western (Earthward) rim of Hédervári crater, 82.2°S 75°E. Whitaker tentatively labels this Leibnitz Epsilon in his sketch.The Moon visualization uses the latest albedo and elevation maps from Lunar Reconnaissance Orbiter (LRO). || ",

"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. || ",

"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. || ",

However, there are some parts of the Moon that never see sunlight. These areas are called permanently shadowed regions, and they appear dark because unlike on the Earth, the axis of the Moon is nearly perpendicular to the direction of the sun's light. The result is that the bottoms of certain craters are never pointed toward the Sun, with some remaining dark for over two billion years. However, thanks to new data from NASA's Lunar Reconnaissance Orbiter, we can now see into these dark craters in incredible detail. || ",

The maps revealed features of the lunar surface and interior in incredible detail, providing scientists with new information about the moon's craggy topography and lumpy crust. Using these maps, researchers will be able to peer back at the moon's early history and better understand its origin and development, along with that of Earth and the other rocky bodies in the solar system.

"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": "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. || ",

"description": "This is a simulation of the Earth's radiation belts. In this version, we've kept the belts full structure. There is also a cross-section view of the belts in Earth's Radiation Belts (cross-section).The Earth's magnetosphere is a very large magnetic structure around the Earth, which gets stretched into a large, teardrop-shaped configuration through its interaction with the solar wind. A number of the magnetic field lines, which they may originate on the Earth, do not connect back to the Earth, but connect into the magnetic field carried by the solar wind. However, near the Earth, the dipole component of the field is stronger than the solar wind field, and this allows all the magnetic field lines to connect back to the Earth, forming (approximately) the classic magnetic dipole configuration. In this region, lower energy electrons and ions, many from the Earth's ionosphere, can become trapped by the magnetic field to form the radiation belts.The radiation belt model is constructed from particle flux information from the SAMPEX mission, with the flux mapped to constant L-shells of the Earth's dipole magnetic field. The model is anchored to the Earth's geomagnetic field axis, which is not perfectly aligned with the Earth's rotation axis. This creates a small wobble of the radiation belts with time, which can be seen in this visualization.The data driving the radiation belt structure is time-shifted from the 2003 Halloween solar storms, a series of strong solar eruptions that began in late October 2003 and continued into the first week of November. During this time, the particle content of the belts change rapidly due to the variation in the energetic particle flux from the Sun buffeting the Earth's magnetosphere. || ",

"description": "The famous color photograph known as Earthrise, as well as a black-and-white image taken a minute earlier, document the moment when Earth was seen for the first time by human eyes from behind the Moon. They were taken on December 24, 1968 by the crew of Apollo 8, the first humans to leave low Earth orbit.The sight of a small, intensely blue Earth rising above the barren, gray horizon of the Moon was one of the few things that NASA and the crew of Apollo 8 had not thoroughly planned and rehearsed beforehand. 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. We came all this way to explore the Moon, Apollo 8 astronaut Bill Anders said, and the most important thing is that we discovered the Earth.Using the latest elevation data from Lunar Reconnaissance Orbiter, this visualization attempts to recreate what the astronauts saw. The virtual camera of the rendering software is put in the position of the Apollo 8 spacecraft at the time of the photographs, as the spacecraft emerged from its fourth pass behind the Moon. It shows a two-minute interval centered on 16:39:06 UT (10:39 a.m. Houston time) on December 24, 1968. This is around the time of AOS (acquisition of signal), the moment when radio contact is re-established after being lost on the far side of the Moon.The position and motion of the spacecraft are based on a state vector, a set of (x, y, z) position and (vx, vy, vz) velocity values, published in NASA's Apollo 8 Mission Report about a year after the flight. The animator translated these values, given in Moon-centered inertial coordinates for Besselian year 1969.0, into a modern coordinate system, then calculated an orbit. The spacecraft was 110 km (68 miles, 60 nautical miles) above the surface of the Moon at 11.2°S 113.8°E when the Earthrise photograph was taken. || ",

"description": "LOLA, the Lunar Orbiter Laser Altimeter aboard the Lunar Reconnaissance Orbiter spacecraft, is an instrument for measuring the altitude of the Moon's terrain. As LRO orbits the Moon, LOLA bounces laser light off the lunar surface 28 times per second. An array of five sensors arranged in an X-shape detects the reflected light. The amount of time it takes the light to travel to the surface and back to the sensors tells the instrument how far away the surface is. Over time, LOLA builds up a complete elevation map of the Moon.This animation illustrates how the X-shaped LOLA sensor footprint travels over the lunar surface. The LOLA data track is taken from LRO orbit number 1155, on September 27, 2009, as the spacecraft passed over Amundsen crater near the lunar south pole. It begins with a distant view showing the entire crater, then switches to a view near the surface that chases the laser pulses over the central peak and across the floor of this large crater. Through most of the movie, the laser pulses are shown racing across the surface at actual speed, but at one point, the pace is slowed so that the viewer can see the sensor pattern of each individual laser pulse.The imagery of the ground view is a high-resolution photograph taken by the LRO narrow-angle camera at the same time this LOLA data track was being recorded. The shape of the terrain in all of the views is taken from LOLA elevation maps. All of this data is publicly available from the Planetary Data System's LRO archive.This is a new and improved version of entry #3758. || ",

"description": "For Lunar Reconnaissance Orbiter (LRO), the lunar eclipse on June 15, 2011 is likely to be the longest and darkest of its life. This matters because LRO relies on sunlight to power its systems and instruments. Although it spends half of every orbit on the night side of the Moon, each night side pass lasts only an hour. For the June 15 eclipse, LRO will be in the dark for more than twice as long.During a previous total eclipse, LRO hibernated, turning off all of its instruments to conserve its battery power until the Moon emerged from the Earth's shadow. For the June 15 event, LRO will leave on the Diviner Lunar Radiometry Experiment. Diviner will measure the cooling of the Moon's surface during the eclipse. This unique temperature record is expected to reveal information about the roughness and composition of the swath of lunar surface visible to Diviner's sensors during the eclipse.The visualization archived on this page shows the view of the eclipse from the Moon, looking back toward the Earth and the Sun. On the Moon, this event is a solar eclipse. As the Sun disappears behind the Earth, the umbral shadow sweeps across the lunar landscape, and as our eyes adjust to the darkness, the stars come out, and the lunar surface looks a dull red. The atmosphere of the Earth lights up as a red ring around the planet, the sunrises and sunsets all around the edge of the globe lending their faint light to the Moon while the Sun is otherwise blocked. At the start of the eclipse, Australia is facing us, but over time, the Moon sets in eastern Australia while southern Africa rotates into view. LRO streaks through the frame several times on its orbit 50 kilometers above the Moon's surface.Other visualizations in this series depict the view of the eclipsealong the shadow line, with the figures of the umbra, penumbra, and lunar and solar pathsthrough a telescope on Earthflying above LRO as Diviner takes temperature measurementsA narrated piece that uses these visualizations is available in entry #10794.

"title": "LRO at the June 15, 2011 Lunar Eclipse: Earth View",
"description": "For Lunar Reconnaissance Orbiter (LRO), the lunar eclipse on June 15, 2011 is likely to be the longest and darkest of its life. This matters because LRO relies on sunlight to power its systems and instruments. Although it spends half of every orbit on the night side of the Moon, each night side pass lasts only an hour. For the June 15 eclipse, LRO will be in the dark for more than twice as long.During a previous total eclipse, LRO hibernated, turning off all of its instruments to conserve its battery power until the Moon emerged from the Earth's shadow. For the June 15 event, LRO will leave on the Diviner Lunar Radiometry Experiment. Diviner will measure the cooling of the Moon's surface during the eclipse. This unique temperature record is expected to reveal information about the roughness and composition of the swath of lunar surface visible to Diviner's sensors during the eclipse.The visualization archived on this page shows the eclipse as it might appear through a telescope on Earth (except that you can't see LRO in such a telescope). Celestial north is up. As the Moon enters the umbra (the part of the shadow in which the Sun is completely blocked by the Earth), the shadowed side of the Moon appears black while the sunlit side remains bright. Only when the Moon is almost completely within the umbra is it possible to see the faint red glow of the shadowed side, some 10,000 times fainter than the sunlit Moon. The redness is sunlight filtered and refracted by Earth's atmosphere. The same effect reddens sunrises and sunsets on Earth.Other visualizations in this series depict the view of the eclipsefrom the Moon, where the event is a solar eclipsealong the shadow line, with the figures of the umbra, penumbra, and lunar and solar pathsflying above LRO as Diviner takes temperature measurementsA narrated piece that uses these visualizations is available in entry #10794. For an explanation of lunar eclipses, visit entry #10787. || ",

This unique temperature record is expected to reveal information about the roughness and composition of the swath of lunar surface visible to Diviner's sensors during the eclipse.The visualization archived on this page shows LRO flying over the lunar surface during the darkest part of the eclipse, with Diviner measuring temperatures along a swath about 3.5 kilometers wide. LRO will pass this part of the surface again during the eclipse, and it will tilt a bit so that Diviner can point at the same strip of lunar surface. The difference between the two temperature readings gives the rate of cooling at each point along the swath.Other visualizations in this series depict the view of the eclipsefrom the Moon, where the event is a solar eclipsealong the shadow line, with the figures of the umbra, penumbra, and lunar and solar pathsthrough a telescope on EarthA narrated piece that uses these visualizations is in entry #10794.

"title": "Ten Cool Things Seen in the First Year of LRO",
"description": "Having officially reached lunar orbit on June 23nd, 2009, the Lunar Reconnaissance Orbiter (LRO) has now marked one full year on its mission to scout the moon. Maps and datasets collected by LRO's state-of-the-art instruments will form the foundation for all future lunar exploration plans, as well as be critical to scientists working to better understand the moon and its environment. In only the first year of the mission, LRO has gathered more digital information than any previous planetary mission in history. To celebrate one year in orbit, here are ten cool things already observed by LRO. Note that the stories here are just a small sample of what the LRO team has released and barely touch on the major scientific accomplishments of the mission. If you like these, visit the official LRO web site at www.nasa.gov/LRO to find out even more! || ",

"title": "Lunar Topography: ULCN versus LOLA",
"description": "This animation illustrates the dramatic improvement in our knowledge of the Moon's terrain made possible by the Lunar Orbiter Laser Altimeter (LOLA) instrument onboard the Lunar Reconnaissance Orbiter (LRO) spacecraft. A LOLA digital elevation map compiled in late 2009 is compared to the Unified Lunar Control Network (ULCN) 2005, a painstakingly constructed map based on the best available data at the time, including imagery from the Clementine, Apollo, Mariner 10, and Galileo missions as well as Earth-based observations.The height of the terrain is color-coded, with blues and greens representing low altitudes and reds representing high altitudes. The LOLA data used to create this media is available to the public in the LOLA archive of the PDS Geosciences node. || ",

"title": "LOLA: Lunar Topography in Natural Color",
"description": "This animation is a brief tour of several prominent features of the Moon's terrain: Tycho crater, the south pole, and the South Pole-Aitken basin. It is match-moved to a companion piece showing the terrain elevations in false color.This is an update of animation 3594, which was produced before the launch of Lunar Reconnaissance Orbiter. Except for the Tycho crater inset, the elevation map in this updated version is based entirely on early results of the Lunar Orbiter Laser Altimeter onboard LRO.The surface appearance is derived from photographs taken by the Clementine spacecraft. Although it shows the visible surface in natural color, this animation does not depict realistic sunlight and shadows. This is especially significant near the poles, where certain parts of the terrain can be in permanent shadow and would never be fully visible in the manner depicted here. || ",
