Considering the greatest impact manned space travel has had on my life is probably freeze dried fruit in my morning cereal, that's a pretty lousy cost-to-benefit ratio.
This has to be one of the most ignorant statements I've ever seen on Slashdot. Between microgravity experiments and the need to engineer new technology for space missions, I doubt a single American goes a single day without technology directly or indirectly resulting from the space program. We have gained tons from going into space, especially in materials science and biotechnology. Lots of good science goes on in space that can't be done on Earth. If anything, we should be doing more, not less.
Do not use the blue keys on this terminal.
