moon strike creates cloud of dust.......

NASA spent millions of dollars shooting a rocket into the moon to create a cloud of dust to see if there was water on the moon. This hopefully will give them data to establish whether there is enough water to sustain life. My question.......why could we have not spent that money digging wells in areas where farmers no longer have water....or dig wells in 3rd world countries where people are dieing for the lack of water.....it seems that we have our priorities all messed up here......if they are just trying to give a lot of intellegent people a job then let me suggest some more constructive ways....such as developing green technologies....feeding the hungry......securing the internet.....i do not know.......things which really affect the majority of Americans lives!
