A trillion dollars is $50 billion per year over 20 years. From the site: “It is proposed that the US dedicate .27% of its GDP each year to the NASA Enterprise program. To get some sense of what spending .27% of the GDP each year will mean, consider that between 1963 and 1972, during the Apollo era, the US spent on average .50% of GDP per year as shown in the center column in the table to the right. This is about double the level of spending proposed for funding the Enterprise program. .27% of GDP will be about $40 billion for the year 2012. $40 billion is certainly a lot of money to spend – but it’s not that much when you consider that the federal budget in 2012 is $3700 billion ($3.7 Trillion). $40 billion seems like pocket change from the perspective of federal spending. $40 billion is 1.1% of the 2012 federal budget. This compares to an average of 2.8% of the federal budget which was spent each year on NASA between 1963 and 1972 as shown in the rightmost column in the table above.”
