            "description": "Since the 1960’s, scientists have suspected that frozen water could survive in cold, dark craters at the Moon’s poles.  While previous lunar missions have detected hints of water on the Moon, new data from the Lunar Reconnaissance Orbiter (LRO) pinpoints areas near the south pole where water is likely to exist.  The key to this discovery is hydrogen, the main ingredient in water: LRO uses its Lunar Exploration Neutron Detector, or LEND, to measure how much hydrogen is trapped within the lunar soil.  By combining years of LEND data, scientists see mounting evidence of hydrogen-rich areas near the Moon’s south pole, strongly suggesting the presence of frozen water. || ",

            "title": "LEND Looks for Water at the South Pole",
            "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. || ",

            "title": "Modeling the LCROSS Impact Site",
            "description": "A two-ton Atlas Centaur rocket body, part of the Lunar Crater Observation and Sensing Satellite (LCROSS), struck the floor of Cabeus crater, near the south pole of the moon, at 11:31 UT on October 9, 2009. 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. The effects of the impact were captured by sensors onboard a shepherding satellite travelling four minutes behind the Centaur. They were also watched by Earth-based observatories and several Earth-orbiting satellites, including the Hubble Space Telescope.The images here were created in the weeks prior to the impact. They visualize the viewing angle, terrain, and shadows around the target crater at the time of the impact. Astronomers in New Mexico, Arizona, California, and Hawaii used them as visual reference while guiding their telescopes. LCROSS project scientists also used these and similar images to evaluate a number of potential impact locations.Using the Jet Propulsion Laboratory's DE421 ephemeris and early terrain data from Lunar Reconnaissance Orbiter's laser altimeter, the artist was able to accurately depict the sunlight direction, shadows, moon orientation, terrain, and field of view for several representative observing locations on the Earth. || ",

            "description": "As the Earth and Moon orbit around the Sun, there are places on the Moon that never receive direct sunlight. Most of these permanently shadowed regions are at the lunar poles. This animation approximates the permanently shadowned regions pertaining to the Moon's south pole by maintaining a maximum sun angle to the surface of 1.5 degrees. These permanently shadowed areas are of interest because they could hold water ice. (NOTE: South Pole Digital Elevation Maps [DEM] based on publically released JAXA/Selene data.) || ",
