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

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.

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. || ", "hits": 307 }, { "id": 4054, "url": "https://svs.gsfc.nasa.gov/4054/", "result_type": "Visualization", "release_date": "2013-03-19T13:00:00-04:00", "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.

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.

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 will be placed in a nearly circular polar orbit about 50 kilometers (31 miles) above the surface of the Moon, completing each orbit in a little less than two hours. The orientation of this orbit remains fixed in space, relative to the stars, while the Moon slowly rotates beneath it as they travel together around the Earth, allowing LRO to scan the entire surface of the Moon every two weeks.The animation depicts LRO's ground track over a period of 27.3 days (348 orbits) or one sidereal month, the amount of time it takes the Moon to turn once on its axis, relative to the stars. This is two days shorter than the synodic month, the period of the Moon's phases. The difference arises from the motion of the Earth. While the Moon is orbiting the Earth, the Earth is carrying them both around the Sun, changing the Sun's direction relative to the stars.Each LRO orbit is separated from the previous one by about one degree of longitude. On the Moon's surface near the equator, this corresponds to a spacing of 30 kilometers (19 miles), but the orbits converge near the poles; at 84 degrees N or S latitude, the ground distance is only 10% of the distance at the equator. At all latitudes, later LRO orbits will fill in the gaps left by earlier ones. Orbits in the latter half of the month depicted in this animation are seen to form a cross-hatch pattern that begins to fill in the gaps left during the first half of the month.The points at which the orbits cross provide an opportunity to refine our knowledge of LRO's precise position. LOLA, the LRO instrument that maps the lunar terrain by measuring surface elevation, should get the same reading for these crossing points each time it passes over them. If it doesn't, then LRO might not really be at a crossing point, meaning that its actual position differs slightly from its predicted position.The elevation map comprises low-resolution data from a number of sources, including the Clementine and JAXA/SELENE spacecraft, combined with high-resolution insets for the regions near the poles.

At just 400 feet from the lunar surface, with only about a minute's worth of fuel remaining, astronauts Neil Armstrong and Edwin 'Buzz' Aldrin saw that their ship's computer was taking them directly into a crater the size of a football field, strewn with SUV-sized boulders. They quickly took control from the computer, flew over the crater and touched down in a smoother area beyond, cutting the engine with just 30 seconds of fuel left. In general, good landing sites need to be level and free from large boulders that could damage or tip the spacecraft as it attempts to land. And it's up to the Lunar Reconaissance Orbiter (LRO) mission to make those landings as safe as possible. Astronauts will want to avoid places with steep slopes that could tip the spacecraft, so LRO includes a laser ranging system that will build an elevation map to show the contours of the polar surface. The instrument, called the Lunar Orbiter Laser Altimeter (LOLA ), records the time it takes for a laser pulse to travel from the spacecraft to the lunar surface and back to calculate the height of the lunar terrain. After a year in orbit aboard LRO, LOLA will have created an elevation map of the polar regions that is accurate to within a half-meter (20 inches) vertically and 50 meters (about 160 feet) horizontally. LRO will also use data from another instrument that measures temperatures to double-check the safe zone map. Temperatures change more rapidly in areas with loose materials (lots of rocks). By analyzing how quickly temperatures change in potential landing zones, planners using the instrument, named Diviner, can rule out areas that appear smooth but actually are likely to be rocky. LRO also carries a pair of eagle-eyed cameras, called the Narrow Angle Cameras (NACs) which together can take images that reveal details as small as a half-meter (almost 20 inches) over swaths 10 kilometers (about 6.2 miles) wide. As LRO orbits over the poles, the moon rotates beneath the spacecraft, and the NACs will gradually build up a detailed picture of the region. It will be used to identify safe landing zones free of large boulders and craters, allowing astronauts to avoid surprises like Apollo 11. LRO is being assembled and managed by NASA Goddard, and is scheduled to be launched in early 2009. NASA plans to have astronauts back on the moon by 2020. As astronauts close in on a new landing site late in the next decade, they can thank NASA Goddard's small robot scout for showing the safest approach. This visualization is a modified stereoscopic version of: #3533: How LRO Will Find Safe Landing Sites on the Moon The modifications applied in the production of the stereoscopic visualization include: extension of the time range of the animation, color adjustments, scale bar and text overlay treatment.The crater depicted in this visualization is ficticious and only intended for illustrative purposes. The visualization begins with the reveal of a digital elevation map showing sample lunar topography illustrating the kind of data that LRO's LOLA instrument will collect. From this topographic data level surface areas can be derived as the first step to determining safe landing sites. Next, an example temperature map of the lunar surface is revealed to show the sort of data Diviner will collect. Changes in surface temperature will help determine small rock hazards, since they retain and release heat at a different rate than the surrounding regolith. Large rock hazards can be found with LROC's surface imagery. Finally, removing rock hazard areas from level surface areas reveals potential safe landing sites for future lunar missions.In this page the visualization content is offered in various modes to accomodate different types of stereoscopic viewing, such as: Left and Right Eye separate, and Left and Right Eye side-by-side combined on the same frame. || ", "hits": 66 }, { "id": 10349, "url": "https://svs.gsfc.nasa.gov/10349/", "result_type": "Produced Video", "release_date": "2008-09-03T00:00:00-04:00", "title": "LRO Scouts for Safe Landing Sites (Narrated)", "description": "The Lunar Reconnaissance Orbiter (LRO) is NASA's scouting mission to prepare for a return to the moon.

In general, good landing sites need to be level and free from large boulders that could damage or tip the spacecraft as it attempts to land. And it's up to LRO to make those landings as safe as possible. Astronauts will want to avoid places with steep slopes that could tip the spacecraft, so LRO includes a laser ranging system that will build an elevation map to show the contours of the polar surface. The instrument, called the Lunar Orbiter Laser Altimeter (LOLA), records the time it takes for a laser pulse to travel from the spacecraft to the lunar surface and back to calculate the height of the lunar terrain. After a year in orbit aboard LRO, LOLA will have created an elevation map of the polar regions that is accurate to within a half-meter (20 inches) vertically and 50 meters (about 160 feet) horizontally. LRO will also use data from another instrument that measures temperatures to double-check the safe zone map. Temperatures change more rapidly in areas with loose materials (lots of rocks). By analyzing how quickly temperatures change in potential landing zones, planners using the instrument, named Diviner, can rule out areas that appear smooth but actually are likely to be rocky. LRO also carries a pair of eagle-eyed cameras, called the Narrow Angle Cameras (NACs) which together can take images that reveal details as small as a half-meter (almost 20 inches) over swaths 10 kilometers (about 6.2 miles) wide. As LRO orbits over the poles, the moon rotates beneath the spacecraft, and the NACs will gradually build up a detailed picture of the region. It will be used to identify safe landing zones free of large boulders and craters, allowing astronauts to avoid surprises like Apollo 11. LRO is scheduled to launch in 2009.For a 3D stereo version of this visualization, please visit animation #3567: How LRO Will Find Safe Landing Sites on the Moon - Stereoscopic versionFor a feature version of this visualization with narration and music, please visit Goddard Multimedia #10349: LRO Scouts for Safe Landing Sites || ", "hits": 108 } ] }
