            "description": "Volcanic, tectonic, erosional and sedimentary landforms are all evident in this elevation model image of a region along the East African Rift at Lake Kivu. The area shown covers parts of Congo, Rwanda and Uganda.Lake Kivu, in the lower left of the image, lies within the East African Rift, an elongated tectonic pull-apart depression in Earth's crust. The rift extends to the northeast as a smooth lava- and sediment-filled trough. Two volcanic complexes are seen in the rift. The one closer to the lake is the Nyiragongo volcano, which erupted in January 2002, sending lava toward the lake shore and through the city of Goma. East of the rift, even more volcanoes are seen. These are the Virunga volcano chain, which is the home of the endangered mountain gorillas. Note that the terrain surrounding the volcanoes is much smoother than the eroding mountains that cover most of this view, such that topography alone is a good indicator of the extent of the lava flows.Elevation data used in this image was acquired by the Shuttle Radar Topography Mission aboard Space Shuttle Endeavour, launched on Feb. 11, 2000. The mission used the same radar instrument that comprised the Spaceborne Imaging Radar-C/X-Band Synthetic Aperture Radar (SIR-C/X-SAR) that flew twice on Endeavour in 1994. || ",

            "description": "The series of visualizations below are derived from satellite imagery and radar sounding. They portray both the location and size of the 31-kilometer-wide impact crater beneath Hiawatha Glacier. They also portray the structure of the glacier ice that flows into and fills the crater.The Hiawatha impact crater was first suspected to exist in the summer of 2015, from examination of a compilation of Greenland's sub-ice topography radar measurements made by NASA over two decades. The visualizations of the subsurface shown below are derived from a spring 2016 airborne survey by Germany's Alfred Wegener Institute, using a new ultrawideband radar sounder developed by the Center for Remote Sensing of Ice Sheets at The University of Kansas. Subsequent helicopter visits to the deglaciated terrain in front of Hiawatha Glacier by scientists from the Natural History Museum in Denmark recovered sediment samples from the main river that discharges water from beneath Hiawatha Glacier, through the northwestern rim breach. Laboratory examination revealed that these sediment samples contained shocked quartz and elevated platinum-group-element concentrations, both signs that the sediment records evidence of the impact of an iron asteroid more than one kilometer wide. The Hiawatha impact crater is potentially one of the youngest large impact craters on Earth.In the visualizations below, the elevation of the topography of the bed, the ice surface and the radar curtains have been exaggerated ten times in order to better illustrate their structure. || ",

            "description": "Since 1993, the Airborne Topographic Mapper or ATM has been monitoring elevation changes of 160 outlet glaciers in Greenland, many of them on an almost annual basis.  Rink Glacier in central west Greenland is one example of a 25-year-long time series of elevation changes.  In these visualizations, elevation data for each aircraft flight over the glacier are illustrated using spheres 1m in diameter, with each sphere representing a specific measurement.  When viewed together, the spheres form sheets defining the observed surface of the glacier for a given year.  The spheres are colored by year, and over time we can see how the glacier's elevation changes. Towards the end of the visualization, the study area of the Rink Glacier is compared to the future coverage of the Ice, Cloud and land Elevation Satellite-2 (ICESat-2), as represented by bright green crisscrossing ground tracks. || ",

            "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 || ",

            "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.) || ",

            "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": "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. || ",

The Magellan spacecraft imaged more than 98 percent of Venus at a resolution of about 100 meters; the effective resolution of this image is about 3 km. A mosaic of the Magellan images (most with illumination from the west) forms the image base. Gaps in the Magellan coverage were filled with images from the Earth-based Arecibo radar in a region centered roughly on 0 degree latitude and longitude, and with a neutral tone elsewhere (primarily near the south pole). The composite image was processed to improve contrast and to emphasize small features, and was color-coded to represent elevation. Gaps in the elevation data from the Magellan radar altimeter were filled with altimetry from the Venera spacecraft and the U.S. Pioneer Venus missions. An orthographic projection was used, simulating a distant view of one hemisphere of the planet. || ",

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). || ",

            "description": "Since Lunar Reconnaissance Orbiter (LRO) entered lunar orbit in 2009, its neutron detector, LEND, has been counting the neutrons coming from the Moon's surface.Neutrons are created when galactic cosmic rays strike atoms in the lunar regolith. These neutrons bounce from atom to atom like billiard balls, losing energy with each collision. Along the way, some of these neutrons escape into space, where LEND can detect them.The presence of hydrogen in the lunar soil reduces the number of neutrons that escape. To map out likely deposits of water ice, LEND scientists look for this deficit of neutrons in the epithermal (medium) energy range.If the deficit were simply due to random fluctuations, the hydrogen map would never coalesce into a sharp image, but as this animation shows, the map of epithermal neutron deficit at the south pole of the Moon improves over time and converges on particular spots. These include especially strong signals in the permanently shadowed parts of Cabeus and Shoemaker craters, where ice would be completely shielded from the sun. But LEND and other missions have found signs of water in places that aren't permanently shadowed while apparently excluding some places that are, both of which are surprising and exciting discoveries. || ",

            "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. || ",

            "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. || ",

            "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. || ",

Months later, after following very different paths to the moon, LRO and LCROSS met once more. LCROSS struck the floor of Cabeus crater, near the south pole of the moon, at 11:31 UT on October 9, 2009. LRO witnessed the impact from its orbit 50 kilometers (30 miles) above the surface.The purpose of the crash was to create a plume of debris that could be examined for the presence of water and other chemicals in the lunar regolith. LRO's early reconnaissance of the moon gave LCROSS mission planners valuable data in the months before LCROSS arrived, allowing them to choose an impact site with a high probability of producing interesting findings. LRO was also there for the event itself, using its array of instruments to gather data in the aftermath of the impact.This animation shows LRO and LCROSS from 5 minutes before to 5 minutes after the impact. Data gathered before the impact is represented by early results from LRO's Lunar Exploration Neutron Detector (LEND). LEND can sense hydrogen, and therefore possible water, in the lunar soil. The area of high hydrogen concentration in Cabeus (purple) is like a bullseye for LCROSS.Data gathered by LRO after the impact is represented by Diviner temperature measurements taken seconds after the crash. Diviner detected the heat from lunar soil melted and vaporized by the enormous energy of the impact. || ",

For the LCROSS impact, LAMP was pointed just above the lunar horizon to watch for the arrival of a rapidly expanding cloud of vaporized debris from the crash.In this animation, the viewer looks down the LAMP boresight and through its narrow window. The LAMP sensor lights up as the leading edge of the expanding vapor cloud passes through its field of view. What's shown here is actually the difference between the data recorded after the LCROSS impact and that recorded on LRO's previous orbit.

A census of the crater population can tell scientists the relative ages of different parts of the surface and reveal information about the make-up of the early solar system.Such a census has been compiled from the elevation data being sent back by the LOLA instrument on Lunar Reconnaissance Orbiter. It comprises over 5000 craters larger than 20 kilometers in diameter. Some conclusions drawn from an analysis of this crater catalog by members of the LOLA team are described in the September 17, 2010 issue of the journal Science.This animation illustrates the process of systematically counting craters. Craters larger than 20 kilometers in diameter light up to show color-coded elevation. Some areas, such as the maria and the Orientale basin, are notably sparse, implying that these areas are younger.

            "title": "LOLA Footprints",
            "description": "A more recent version of this animation can be found here.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. || ",

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. || ",

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. || ",

The height of the terrain is color-coded, with blues and greens representing low altitudes and reds representing high altitudes. Highlighted are two large \"continents,\" or highlands, Aphrodite Terra and Ishtar Terra; the Maxwell Montes mountain range; and Maat Mons, a large, currently dormant volcano.Magellan arrived at Venus in August of 1990 and spent four years there collecting data. The elevation map used here was created with data collected during the first mapping cycle. Many of the coverage gaps, represented here by black pixels, were filled in during later mapping cycles. || ",
