On June 18 NASA launched the Lunar Crater Observation and Sensing Satellite (LCROSS) from Cape Canaveral in Florida on its journey to the moon.
When the space craft arrives near the moon it will fire a missile, at twice the speed of a bullet, from the spacecraft into the moon's surface. NASA maintains that the "test" will displace several miles of lunar material in order to find out if water is present on the moon's surface.
NASA will then have the $511 million mission's mother satellite circle the moon for at least a year creating a detailed map of the moon's surface. NASA says the new maps will be crucial for identifying possible landing sites for astronauts in future years as permanent bases are built on the moon for the eventual mining of helium-3. Scientists have long suggested that helium-3 could be used for fusion power back here on Earth and would make the profits of the oil industries pale in comparison.
NASA has publicly maintained in recent years that all of their space missions are now "dual use" - meaning that each mission they launch is both civilian and military at the same time. Thus one must consider that this LCROSS moon bombing mission is likely testing the capability of Pentagon technologies to launch missiles from space that could hit targets on Earth.
As the US and Russia enter negotiations to reduce the numbers of nuclear weapons in their stockpiles I can assure you that Russia will be thinking about this LCROSS test. They know that the US is developing "first-strike" capability from space and from Earth. Add "missile defense" into the equation, which would give the US the shield after the first-strike sword has been thrust, and one can see that these new technologies will only "complicate" hopes for the abolition of nuclear weapons.
