中国日报网环球在线消息:美国航天局13日宣布，该局科学家对月球坑观测和传感卫星获得的撞月数据进行初步分析后确认，月球存在水。
美航天局发表新闻公报说，半人马座火箭、月球坑观测和传感卫星10月9日相继撞击了月球南极附近的凯布斯坑，重约2．2吨的半人马座火箭撞月后掀起的尘埃，一部分由蒸汽和微尘组成；另一部分由质量更重的物质组成。月球坑观测和传感卫星携带的光谱仪对尘埃进行了分析。
美航天局负责这一项目的首席科学家安东尼·科拉普雷特表示，初步分析结果表明，上述两部分尘埃中都存在水的踪迹，"尽管月球上水和其他物质的浓度和分布情况还需进一步分析才能确认，但可以放心地说，凯布斯坑中存在水"。

中新社华盛顿十一月十三日电(记者 李静)美国航天局上月实施“撞月”计划获取的信息显示，月球上存在水。
“真真切切，我们发现了水，不是一点点，而是相当多。”美国航天局负责月球坑观测和传感卫星计划的首席科学家安东尼·科拉普雷特十三日在记者会上如是称。
科拉普雷特表示，“撞月”计划在月球上击起一点六公里高的尘埃，其中含有约二十五加仑的水。
探知月球表面下是否有水的存在，航天局上月九日发射月球坑观测和传感卫星与半人马座火箭，撞向预先被选定的月球南极一个陨石坑。航天局发表新闻公报说，半人马座火箭撞月后掀起了两部分尘埃:一部分由蒸汽和微尘组成；另一部分由质量更重的物质组成。初步分析结果提供了多种证据表明，上述两部分尘埃中都存在水的踪迹。
“尽管月球上水和其他物质的浓度和分布情况还需进一步分析才能确认，但可以放心地说，凯布斯陨石坑中存在水。”科拉普雷特说。
美国航天局的官方网站称，这一成果为人类了解月球翻开了新篇章。
美国航天局华盛顿总部的首席月球科学家迈克尔·瓦格说:“我们正在揭开邻居的神秘面纱，从而了解整个太阳系。事实证明，月球蕴藏着很多秘密，而‘撞月’带我们进入了一个新的探知层次。”
科学家们此前曾探测得知月球南北两极地区蕴含丰富的氢，由此推测月球极地可能含有丰富的水冰。而在此次“撞月”之后，科学家们相信水冰或许在月球上有更广的分布。
美国航天局计划二0二0年前派宇航员重返月球。而水的发现据信将有力推动人类探月计划的开展。(完)

CNN新闻： http://www.cnn.com/2009/TECH/spa ... oon.nasa/index.html
(CNN) -- 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.
"I'm here today to tell you that indeed, yes, we found water. And we didn't find just a little bit; we found a significant amount" -- about a dozen, two-gallon bucketfuls, he said, holding up several white plastic containers.
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.
Michael Wargo, chief lunar scientist at NASA headquarters in Washington, said the latest discovery also could unlock the mysteries of the solar system.
He listed several options as sources for the water, including solar winds, comets, giant molecular clouds or even the moon itself through some kind of internal activity. The Earth also may have a role, Wargo said.
"If the water that was formed or deposited is billions of years old, these polar cold traps could hold a key to the history and evolution of the solar system, much as an ice core sample taken on Earth reveals ancient data," NASA said in its statement.
"In addition, water and other compounds represent potential resources that could sustain future lunar exploration."

LCROSS Impact Data Show Water on the Moon
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 two-part plume of material from the bottom of the crater. The first part was a high angle plume of vapor and fine dust and the second a lower angle ejecta curtain of heavier material. This material has not seen sunlight in billions of years.
"We're unlocking the mysteries of our nearest neighbor and by extension the solar system. It turns out the moon harbors many secrets, and LCROSS has added a new layer to our understanding," said Michael Wargo, chief lunar scientist at NASA Headquarters in Washington.
Scientists have long speculated about the source of vast quantities of hydrogen that have been observed at the lunar poles. The LCROSS findings are shedding new light on the question of water, which could be more widespread and in greater quantity than previously suspected.
Permanently shadowed regions could hold a key to the history and evolution of the solar system, much as an ice core sample taken on Earth reveals ancient data. In addition, water, and other compounds represent potential resources that could sustain future lunar exploration.
Since the impacts, the LCROSS science team has been working almost nonstop analyzing the huge amount of data the spacecraft collected. The team concentrated on data from the satellite's spectrometers, which provide the most definitive information about the presence of water. A spectrometer examines light emitted or absorbed by materials that helps identify their composition.
"We are ecstatic," said Anthony Colaprete, LCROSS project scientist and principal investigator at NASA's Ames Research Center in Moffett Field, Calif. "Multiple lines of evidence show water was present in both the high angle vapor plume and the ejecta curtain created by the LCROSS Centaur impact. The concentration and distribution of water and other substances requires further analysis, but it is safe to say Cabeus holds water."
The team took the known near infrared spectral signatures of water and other materials and compared them to the spectra collected by the LCROSS near infrared spectrometer of the impact.
"We were only able to match the spectra from LCROSS data when we inserted the spectra for water," said Colaprete. "No other reasonable combination of other compounds that we tried matched the observations. The possibility of contamination from the Centaur also was ruled out."
Additional confirmation came from an emission in the ultraviolet spectrum that was attributed to hydroxyl, one product from the break-up of water by sunlight. When atoms and molecules are excited, they release energy at specific wavelengths that are detected by the spectrometers. A similar process is used in neon signs. When electrified, a specific gas will produce a distinct color. The ultraviolet visible spectrometer detected hydroxyl signatures just after impact that are consistent with a water vapor cloud in sunlight.
Data from the other LCROSS instruments are being analyzed for additional clues about the state and distribution of the material at the impact site. The LCROSS science team along with colleagues are poring over the data to understand the entire impact event, from flash to crater, with the final goal being the understanding of the distribution of materials, and in particular volatiles, within the soil at the impact site.
"The full understanding of the LCROSS data may take some time. The data is that rich," said Colaprete. "Along with the water in Cabeus, there are hints of other intriguing substances. The permanently shadowed regions of the moon are truly cold traps, collecting and preserving material over billions of years."
LCROSS was launched June 18, 2009 as a companion mission to the Lunar Reconnaissance Orbiter, or LRO, from NASA's Kennedy Space Center in Florida. After separating from LRO, the LCROSS spacecraft held onto the spent Centaur upper stage rocket of the launch vehicle, executed a lunar swingby and entered into a series of long looping orbits around the Earth.
After traveling approximately 113 days and nearly 5.6 million miles (9 million km), the Centaur and LCROSS separated on final approach to the moon. Traveling as fast as a speeding bullet, the Centaur impacted the lunar surface shortly after 4:31 a.m. PDT Oct. 9 with LCROSS watching with its onboard instruments. Approximately four minutes of data was collected before the LCROSS itself impacted the lunar surface.
Working closely with scientists from LRO and other observatories that viewed the impact, the LCROSS team is working to understand the full scope of the LCROSS data. LRO continues to make passes over the impact site to give the LCROSS team additional insight into the mechanics of the impact and its resulting craters.

这个Cabeus陨石坑有个特点 在极地地区 太阳永远不会在地平线上方大约1.5度以上的区域出现 也就是说 陨坑壁将永久性地遮住陨坑底部 使其永远处于黑暗之中
可能是我刚才要表达的意思不够明确 呵呵 撞击点是Cabeus的底部 这个底部是永久阴影区

口水????
{:wugu:}是不是我记错了，貌似三哥早就宣布过月球上有水了。。。
如果是冰状的那还不错，如果还是H和O2分离状态，那就不太好。。。
