            "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": "Lunar Reconnaissance Orbiter (LRO) and the Lunar Crater Observation and Sensing Satellite (LCROSS) were launched together on the same Atlas V rocket on June 18, 2009. 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. || ",

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.

            "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. || ",
