how much water is on the moon

The concentrations of this water are unclear, but ~1000 ppm (0.01 wt.%) is a reasonable estimate. GRAIL mission scientists have solved a lunar mystery almost as old as the moon itself.

Moreover, this material is spatially variable in concentration and temporally variable with the time of day, being stronger in the cooler early morning and late afternoon, local time. Having ready supplies of water on the lunar surface would be a boon for colonists there, because it is so expensive to transport from Earth. This view of the rising Earth greeted the Apollo 8 astronauts as they came from behind the moon after the lunar orbit insertion burn. Surveyor 5 image of the footpad resting in the lunar soil. Clues that the Moon hosts water … They were able to detect a specific signature of H2O that is not shared by other compounds. Since man first touched the moon and brought pieces of it back to Earth, scientists have thought that the lunar surface was bone dry. All rights Reserved. "These results have implications for how humans might extract water to sustain a habitation or make fuel," Associate Professor Alice Gorman from Flinders University, who was not involved in the study, said. The rocks and regolith that make up the lunar surface are about 45 percent oxygen (combined with other elements as mostly silicate minerals). M3′s observations also showed that the water signal got stronger toward the polar regions. "Extraction from small craters might be less technically demanding than mining the big ice craters, but it may also be more destructive to a unique landscape of shadows and ice... As we learn more about the lunar water cycle, it seems that water might be a renewable resource. Advertising Notice "The temperatures are so low in cold traps that ice would behave like a rock," Hayne said in a statement. The new findings, detailed in the Sept. 25 issue of the journal Science, come in the wake of further evidence of lunar polar water ice by NASA’s Lunar Reconnaissance Orbiter and just weeks before the planned lunar impact of NASA’s LCROSS satellite, which will hit one of the permanently shadowed craters at the moon’s south pole in hope of churning up evidence of water ice deposits in the debris field.

LOLA found that the floors of polar dark craters are slightly but distinctly “brighter” (higher albedo) than other crater interiors, interpreted as indicative of the presence of water frost. The moon rocks were analyzed for signs of water bound to minerals present in the rocks; while trace amounts of water were detected, these were assumed to be contamination from Earth, because the containers the rocks came back in had leaked. The second study, led by Dr Paul Hayne from the University of Colorado, Boulder, examines how the Moon captures and stores this water in "cold traps". While previous lunar missions have detected hints of water on the moon, new data from the Lunar Reconnaissance Orbiter pinpoints areas near the south pole where water is … One ton of the top layer of the lunar surface would hold about 32 ounces of water, researchers said. The first paper, led by Dr Casey Honniball from the University of Hawaiʻi at Mānoa, reports the unequivocal discovery of water on the surface of the Moon. Just last week, NASA announced a $47 million commercial contract to send an ice-seeking drill to the Moon in 2023.
