            "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. || ",

            "title": "Earthrise",
            "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": "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 along the axis of the Earth's shadow, with the figures of the umbra, penumbra, and lunar and solar paths in the background. This is the view typically used in eclipse diagrams like those produced by Fred Espenak for the NASA Eclipse site.Other visualizations in this series depict the view of the eclipsefrom the Moon, where the event is a solar eclipsethrough a telescope on Earthflying above LRO as Diviner takes temperature measurementsA narrated piece that uses these visualizations is available in entry #10794.

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.

One of the instruments on board is the  Lunar Orbiter Laser Altimeter (LOLA) which measures landing site slopes, lunar surface roughness, and has begun generation of a high resolution 3D map of the Moon. The animation depicted here is the beginning of  LOLA's mapping project and shows the lunar south pole through digital elevation map data collected by the  LOLA instrument during the spacecraft commissioning phase. During the commissioning phase, LRO was in a highly elliptical orbit coming closer to the lunar south pole than the north pole. Furthermore, since  LOLA uses laser pulses to measure the surface, the accuracy of its measurements are greatly affected by the instrument's distance to the surface. This is why there is virtually no data of the lunar north pole, and much better coverage of the south pole. The topographic data shown here is currently processed to show at approximately 30 meters per pixel.The colors in this animation depict the relative heights of the lunar surface with respect to the surface mean. Warm colors (brown, red, magenta, and tan) indicate areas above the mean. Cooler colors (green, cyan, blue, and violet) are areas below the mean. || ",
