Why is Obama letting NASA bomb the Moon?

idk y but to me it sounds worthless.We already know there's water on mars.why do they want to do that.How will that affect us right now?? what will they do next?? bomb every other planet too?. he should be freacking worrying on fixing the economy not bombing the outer space.Geez.waste of time and money on bombing the moon which might prove to not even have water.im getting upset by their actions right now >=[
