Money isn't NASA's only problem, but it has been its biggest problem for decades. NASA is one of the most successful agencies in history, providing the best return on investment of any government agency in my lifetime. My main concerns with NASA's plans going forward include the decision to ground the space shuttle, the woefully inadequate funding for the last several decades and the absence of a space program that will restore the sense of wonder and adventure to space exploration that we knew in the 1960s.
