Respected All Members,
Just recently I read this news at CNN news site and want to share with you all.
NASA said Friday it had discovered water on the moon, opening "a new chapter" that could allow for the development of a lunar space station.
The discovery was announced by project scientist Anthony Colaprete at a midday news conference. "Indeed, yes, we found water," he said.
The find is based on preliminary data collected when the Lunar Crater Observation and Sensing Satellite, or LCROSS, intentionally crashed October 9 into the permanently shadowed region of Cabeus crater near the moon's south pole.
After the satellite struck, a rocket flew through the debris cloud, measuring the amount of water and providing a host of other data, Colaprete said.
The project team concentrated on data from the satellite's spectrometers, which provide the best information about the presence of water, Colaprete said. A spectrometer helps identify the composition of materials by examining light they emit or absorb.
Although the goal of the $79 million mission was to determine whether there is water on the moon, discoveries in other areas are expected as studies progress, Colaprete and other scientists said at the briefing at NASA's Ames Research Center at Moffett Field near San Francisco, California.
"The discovery opens a new chapter in our understanding of the moon," the space agency said in a written statement shortly after the briefing began.
