laser surgery is wonderful for people diagnosed with cancer. It is less invasive. Sure prevention is great but some children and others that live healthy life styles still get cancer. I thank God and NASA for the wonderous things they have done to improve our health, day to day life and so much more...too bad you do not grasp that! I stated that was a drop in the bucket as to the many innovations accomplished. I support space exploration and agree with Newt.
