            "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). || ",

            "description": "Using elevation and image data returned by Lunar Reconnaissance Orbiter (LRO), this animation takes the viewer on a virtual tour of the Moon. The tour visits a number of interesting sites chosen to illustrate a wide variety of lunar terrain features. Some are on the near side and are familiar to both professional and amateur observers on Earth, while others can only be seen clearly from space. Some are large and old (Orientale, South Pole-Aitken), others are smaller and younger (Tycho, Aristarchus). Constantly shadowed areas near the poles are hard to photograph but easier to measure with altimetry, while several of the Apollo landing sites, all relatively near the equator, have been imaged at resolutions as high as 25 centimeters (10 inches) per pixel.The shape of the terrain in this animation is based primarily on data from LRO's laser altimeter (LOLA), supplemented by stereo image data from its wide angle camera (LROC WAC) and from Japan's Kaguya mission. The global surface color is from Clementine. || ",

One of its primary objectives will be to assess the lunar terrain for areas that would provide safe landing sites for future missions, both manned and unmanned, that plan to touch down on the moon's surface. This video helps explain how LRO will accomplish its objective.This visualization is a modified 3D stereo version of animation entry:#10349: LRO Scouts for Safe Landing Sites.The raw stereoscopic visualization sequence used to create this narrated animation can be viewed and downloaded from entry:  #3567: How LRO Will Find Safe Landing Sites on the Moon - Stereoscopic Version. || ",

            "description": "The first attempt to land humans on the moon - Apollo 11 - was a triumph that almost ended in disaster. 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. || ",
