Well, not quite the end of US manned space flight - Endeavour still has a flight planned. But that one should be the last, so the beginning of the end at the very least. And yeah, Discovery's done.
When you think of all the advances space flight pushed us to achieve in the last 50+ years, it makes one wonder how much further we could have gone.
