600 million tons of water to the moon is expected to become space "filling
According to the British New Scientist magazine, for the lunar exploration scientists, is now the best time to explore the moon, but also "the worst" period. NASA Ames Research Center's Creek – Elphick (RickElphic) said: "At present we have the lunar surface in-depth understanding of knowledge, the recent three lunar exploration mission confirmed the existence of 3 different forms of the Moon Water resources to further promote the future of immigration on the moon of human passion, while the investigation found that the moon has production capacity of fuel in space, it is expected to become the next space 'gas station', a solar system to explore the staging of other stars. "
NASA Mini-SAR radar, the moon more than 40 sizes ranging from the Arctic (about 1.6 to 15 kilometers) of the crater, each crater filled with water ice. NASA scientists said, "Although the water depends on the thickness of ice water every crater in the ice thickness, but it is estimated that at least 600 million tons of water ice."
Lunar exploration mixed However, future astronauts on the moon exploration program was quickly poured cold water this year in February, Barack Obama announced his intention to cancel NASA, "Constellation" program, which includes 20 years of this century send astronauts to the moon early again.
However, after 2010 the world started to increase research efforts to the moon, the Obama Government plans to provide substantial financial resources of the solar system for robotic exploration, including lunar included. NASA has carried out four robotic missions to explore the moon's atmosphere, gravity, and seismology. NASA has successfully developed a new generation of middle-size robot?? "Rose (MoonRise)" will perform one of the tasks planned landing the lunar south pole Aitken basin, excavation soil samples sent back to the ground. In addition, China and India launched the "Change" and the "No. 1 Indian Moon (Chandrayaan-1)" detector, Russia and Germany are also planning a survey plan.
2009, the NASA Lunar Reconnaissance Orbiter (LRO) and Lunar Crater Observation and Sensing Satellite (LCROSS) found water on the moon, the moon investigation set off a revolution, after the moon on the 1st of India have also detected the existence of lunar water. India's Moon 1 Moon Mineralogy Mapper chief scientist Carl – Peters (CarlePieters) said: "probe the lunar surface was found not only in water, and were found in 3 different types of water." She referred to the moon in 2008 1 deep volcanic soil on the moon crystal to a large number of water molecules in the investigation, the Moon Crater Observation and Sensing Satellite, also found in the lunar polar water molecules. The water molecule is completely different, they are from different sources, and each has its far-reaching significance.
Moon damp of historical perspective and found
Wet in the history of the theory on the moon that have divergent, the early 17th century after Galileo's telescope to detect the moon, scientists were widely thought to exist at the time the water. Surface of the moon dark spot is called "Maria" in Latin means ocean, but to the late 17th century view of the scientific community is a further point to the moon Arid Stars. Of the last century, "Apollo" moon surface, and lunar rock samples brought back to the ground, when NASA announced that the rock samples, "as dry as the Skeleton." Research since then to break the traditional concepts of lunar soil contains the hydrogen from the solar wind ions, the chemical in the unstable price structure, a large amount of oxygen atoms, which means that hydrogen ions can be attached to the oxygen atoms to form water substances, such as: hydroxyl (OH-) or water molecules.
1977, the NASA Johnson Space Center Everett – Gib Johnson (EverettGibson) confirmed in experiments Apollo rock samples collected will release water when heated, and hydroxyl. However, he failed to change the traditional lunar rock is dry and judgments. At the same time, the University of California San Diego, James – Arnold (JamesArnold) pointed out that water may exist near the lunar poles, before the Apollo had not been detected in the region. As the lunar polar regions receive little exposure to the sun's rays, some deep craters within almost never shine any light. Craters such as this can serve as a "cold trap", used to collect water, thin moon, the atmosphere of any volatile compounds.
