More water on the moon that was thought!

There is more water on the moon in more locations than originally thought, a discovery that may bolster NASA’s long-held goal of setting up an outpost there, a researcher said.
One ton of the moon’s surface — in which the water’s ingredients are held — could yield as much as 32 ounces, or one quart, of water, according to three reports from research teams who studied data from three spacecrafts.
Although that amount isn’t large, said geological sciences professor Jack Mustard, the findings show “there are ways you could convert these amounts of water into higher amounts” that could support human activity.
The water was discovered in rocky environments and in craters, Mustard said.
“It’s in more places and in different places than were inferred previously,” he said.
Since the Apollo missions began in the 1960s, scientists have believed the moon was virtually dry. Only trace amounts of water were found in rocks and soil brought back to Earth, and that water may have resulted from contamination during the retrieval process, scientists said.
Mustard was on a team led by Carle Pieters, science manager of the NASA-supported Keck Reflectance Experiment Laboratory at Brown University in Providence, Rhode Island.
Pieters also is principal investigator for NASA’s Moon Mineralogy Mapper (M3), which the space agency contributed to India’s first mission to the moon, Chandrayaan-1, in October 2008. The mapper was a “state-of-the-art imaging spectrometer” that provided the first map of the entire lunar surface at high resolution, revealing the minerals of which it is made.
Examining data from Chandrayaan-1, Pieters’ team found signs of water at the moon’s frigid poles. The researchers believe it might have migrated from elsewhere on the moon’s surface, attracted by the cold, they said.
Their overall findings also were confirmed by data from a high-tech spectrometer on the Cassini spacecraft — which also found evidence of water at lower latitudes away from the poles — and from infrared mapping done by the Deep Impact spacecrafts — which found trace amounts over much of the moon’s surface.

Minister of Energy and Water Development Kenneth Konga says preliminary investigations into the cause of the fire that broke out at Kariba North Bank Power Station on September 18, 2009 have revealed that the accident was partly caused by negligence and non-adherence to safety procedures.
