First, a NASA administrator would be named to a ten year term. The intent is to provide some continuality in the way the space agency is run and to remove it, as much as possible, from the vagaries of politics.
Second, NASA funding would be placed on a multi-year rather than annual cycle. This is of particular importance to the space agency because the majority of its high level projects take several years to run their course. If funding were fixed for a number of years, the theory goes, money could be spent more efficiently. NASA planners would know how much they have to spend four or so years going forward and would not have to worry about being cut off at the knees by Congressional appropriators year after year."
