I hate the idea of losing NASA but they do need to come back to reality. I think they loost their way back in the 70's with the space shuttle. I think this is another case similar to the B1 or the destroyer in the other thread. NASA wants big toys with all the latest bells and whistles. The shuttle was a nice idea but way to complex. They had a overly optimistic (putting at as nice as I can) plan of launches which they never even came close to achieving. The reliability was horrible. Granted it lasted well beyond it's planned operational life span but I do not think it was worth what we put into it.
Just look at the Russian space program and then look at ours. We far out spent them and our toys were far more advanced but look who has the most space hours. To say yhat e are getting our butts handed to us is an understatement. As of July 2010 the Russians have spent 34,710 crew-days in space. The US has spent a whooping 151 crew days. Nearly every single record in space has been set by the Russians. The top ten astronauts with the most flight time are all Russian. Top ten single flight durations, 9 are Russian 1 was on the ISS.
Look at the space stations. Skylab was launched in '73 and bit the dust in '79. The Mir was launched in '86 and did not come down till 2001 and they forced it down. Granted it was held together with duct tap and chewing gum but no one died on it and it got the job done.
NASA has not served us well in my opinion. They have done some amazing stuff but they could have done far more with far less money had they designed space crafts that would do the job instead of trying to reinvent the wheel.
