These video's come from Neil deGrasse Tyson. These video's go into the important's of NASA and how the government keeps cutting money from it. The government says we don't have the money for NASA. Yet we have the money to spend on wasteful programs that don't work many of which cost as must as a 100 billion dollars or more a year. So cut money from these wasteful programs instead of NASA. Does anyone actual know how little we spend on NASA. Its a half a penny on a dollar. If we can afford a trillion dollars on a wasteful war in Iraq which got us nothing, then I think we can afford NASA.
