Can see ending the cost-inefficient space shuttle program, but cancelling its successor spacecraft too thereby making the US a non-spacefaring nation? What exactly was the point of building the ISS if now we can't get to it without hitching a ride? Anyone else wonder if maybe the aliens are real and told us like, "We're sick of seeing you up there. End your manned spaceflights or else?" :) Supposedly, President Obama said it was to save money. But NASA's entire annual budget is only like $17 billion. This year's DoD budget is $648 billion. If ya really wanna save money coulda easily found some wasteful spending there and kept the Constellation program.
