Congress does not understand the REAL importance of NASA. All they can do is discuss how much they want man to go to Mars, national leadership in space, etc. But every space-oriented scientist knows that the REAL importance of NASA is the unmanned scientific missions they launch. Science and mankind have been IMMENSELY enriched by these, MUCH more so than any results from manned missions. Scientists understand that manned missions are a huge drain on the economy and learn little. I hope the OSTP will take this lesson to heart and champion unmanned missions over manned.
