Water Discovered in Moon Shadow Credit: LCROSS, NASA Explanation: Why is there water on the Moon? Last month, the LCROSS mission crashed a large impactor into a permanently shadowed crater near the Moon's South Pole. A plume of dust rose that was visible to the satellite, although hard to discern from Earth. The plume is shown above in visible light. Last week, the results of a preliminary chemical analysis gave a clear indication that the dust plume contained water. Such water is of importance not only for understanding the history of the Moon, but as a possible reservoir for...

NASA claims definitive detection of Moon water in the Solar System's 'attic'.On the way to a wet landing.N. GRUMMAN, W. FURLONG/NASA The debate is finally over. Lunar scientists have detected water for certain near the north pole of the Moon, after the impact of a NASA projectile kicked up water vapour along with a plume of dust. But it's not just about the water, say the scientists, who found hints in the plume of other, more exotic molecules, ranging from organic hydrocarbons to mercury. Increasingly, the scientists are viewing the polar craters as the 'attics' of the Solar System, repositories...

The argument that the moon is a dry, desolate place no longer holds water. Secrets the moon has been holding, for perhaps billions of years, are now being revealed to the delight of scientists and space enthusiasts alike. NASA today opened a new chapter in our understanding of the moon. Preliminary data from the Lunar CRater Observation and Sensing Satellite, or LCROSS, indicates that the mission successfully uncovered water during the Oct. 9, 2009 impacts into the permanently shadowed region of Cabeus cater near the moon’s south pole. The impact created by the LCROSS Centaur upper stage rocket created a...

There was a plume after all. Observers on Earth had their doubts after LCROSS and its Centaur booster rocket hit the Moon on Friday, Oct. 9th. The twin lunar impacts failed to produce visible plumes of debris, prompting speculation that something had gone wrong. On the contrary, members of the LCROSS science team are now calling the experiment "a smashing success." Fifteen seconds after the Centaur hit the shadowy floor of crater Cabeus, the LCROSS spacecraft flying 600 km overhead took the following picture of a plume measuring 6 to 8 km wide: "There is a clear indication of a...

Credit: Palomar Observatory/Caltech NASA officials and scientists spent the better part of an hour in this morning's press conference patting themselves on the back. The LCROSS mission in search of lunar water was a great success, they said, all the while ignoring a very large elephant in the room: No one among the millions watching as a 2-ton hunk of metal slammed into the moon could see the much-ballyhooed spray of dust and debris that they had been told...

WASHINGTON —  Take that, moon! NASA bulldozed two spacecraft into the lunar south pole Friday morning in a search for hidden ice. Instruments confirm that a large empty rocket hull barreled into the moon at 7:31 a.m., followed 4 minutes later by a probe with cameras taking pictures of the first crash. But initial photos show that the moon didn't give the reaction to the double jabs that NASA expected. And the public definitely didn't get the live explosive views they may have anticipated from the mission called LCROSS, short for Lunar Crater Observation and Sensing Satellite. Screens got fuzz and...

NASA's Lunar Prospector first detected some hydrogen signatures in craters on the dark side of the moon in 1999. Ever since, researchers have been keen to confirm the presence of water on the moon. The Lunar CRater Observing and Sensing Satellite (LCROSS) is tasked with crashing through the mists of speculation and conjecture and discover the truth. And you can watch all the action as it happens. LCROSS was launched on June 18th and executed a fly-by of the moon five days later before entering into a wide orbit. On Friday October 9th, the craft will start to make...

Scientists are priming two spacecraft to slam into the moon's South Pole to see if the lunar double whammy reveals hidden water ice. The Earth-on-moon violence may raise eyebrows, but NASA's history shows that such missions can yield extremely useful scientific observations. "I think that people are apprehensive about it because it seems violent or crude, but it's very economical," said Tony Colaprete, the principal investigator for the mission at NASA's Ames Research Center in Moffett Field, Calif. NASA's previous Lunar Prospector mission detected large amounts of hydrogen at the moon's poles before crashing itself into a crater at the...

Quest to find water on the moon moves closer to launch NASA NEWS RELEASE Posted: January 14, 2008 MOFFETT FIELD, Calif. - Cameras and sensors that will look for the presence of water on the moon have completed validation tests and been shipped to the manufacturer of NASA's Lunar Crater Observation and Sensing Satellite. The science instruments for the satellite, which is known as LCROSS, departed NASA's Ames Research Center in Moffett Field Calif., for the Northrop Grumman Corporation's facility in Redondo Beach, Calif. to be integrated with the spacecraft. A video file is available on NASA Television. LCROSS is...
