Originally posted by AlphaHawkI suppose once the laser decimates an Indian or Chinese spacecraft the spectrometers onboard will be used to see what their crafts were made of, right?
On 21 August 2009 Chandrayaan-1 along with the Lunar Reconnaissance Orbiter attempted to perform a bistatic radar experiment using their Mini-SAR radars to detect the presence of water ice on the lunar surface.]
However, at 09.02 (UTC) on 29 August 2009 communication with the spacecraft was suddenly lost.

Originally posted by AlphaHawkSo, with the above facts, you want us to believe that NASA fired a laser at Chandrayaan to destroy it while it was carrying NASA instruments to partake in an experiment that was preplanned by NASA and the Indian Space agency?
Mini-SAR, designed, built and tested for NASA by a large team that includes the Naval Air Warfare Center, Johns Hopkins University Applied Physics Laboratory, Sandia National Laboratories, Raytheon and Northrop Grumman. Mini-SAR is the active Synthetic Aperture Radar system to search for lunar polar ice. The instrument transmitted right polarised radiation with a frequency of 2.5 GHz and monitored scattered left and right polarised radiation. The Fresnel reflectivity and the circular polarisation ratio (CPR) are the key parameters deduced from these measurements. Ice shows the Coherent Backscatter Opposition Effect which results in an enhancement of reflections and CPR, so that water content of the Moon's polar regions can be estimated.
On 21 August 2009, (LRO) the spacecraft, along with the Chandrayaan-1 orbiter, attempted to perform an bistatic radar experiment to detect the presence of water ice on the lunar surface.
After suffering from several technical issues including failure of the star sensors and poor thermal shielding, Chandrayaan stopped sending radio signals at 1:30 AM IST on 29 August 2009 shortly after which, the ISRO officially declared the mission over. Source Wikpedia
The Committee for the Re-Election of the President (also known as the Committee to Re-elect the President), abbreviated CRP but often mocked by the acronym CREEP, was a fundraising organization of United States President Richard Nixon's administration. Besides its re-election activities, CRP employed money laundering and slush funds and was directly and actively involved in the Watergate scandal. Source wikipedia
KREEP, an acronym built from the letters K (the atomic symbol for potassium), REE (Rare Earth Elements) and P (for phosphorus), is a geochemical component of some lunar impact breccia and basaltic rocks. Indirectly, it has been deduced that the origin of KREEP is contained in the origin of the Moon. Source Wikipedia

“NASA already is working to find asteroids that might be a threat to our planet,” said NASA Deputy Administrator Lori Garver shortly after the Chelyabinsk meteorite hit Russia on February 15. “While we have found 95 percent of the large asteroids near the Earth's orbit, we need to find all those that might be a threat to Earth.”
On the same day that all eyes were on DA14, a meteor measuring less than 60 feet across unexpectedly screamed into Earth's atmosphere and exploded over the Russian city of Chelyabinsk, injuring more than 1,500 people. It is space debris this size that is not yet on NASA’s diagram, and the map would be even more crowded if their presence was included.
