Even low earth orbit is deleterious to a human's health. Bone mass loss and other things that go to hell when they are out of the gravity well they were constructed in. By just a tiny amount. The gravity is still about 90% where they hang out. Free fall is not real lack of gravity.<quoted text>
I would agree with you on the benefits of NASA and its contribution to society and including national pride. On the down side the Space Shuttle Program came with a high price of human life. We know both of the shuttle disasters could have been prevented.
We have abandoned the Shuttle Program and were going back to the multi stage rocket deployments. Im one who thinks NASA needs a new and more realistic long term goals. Going beyond Earths orbit with man space flight to Mars for example is a waste of tax dollars.
I have grown to love NASAs unmanned space exploration. This should be the path NASA should continue to follow. The Hubble Telescope has been a magnificent tool for astronomy. The Mars Rovers have performed exceptionally well. Robotics is the future for NASA. Manned space flight should remain in low Earth orbit.
The body and mind were designed to work here.
For all their big talk, the physicists can't even provide a physical environment to maintain the forces we were designed for.
