NASA Kennedy Space Center just posted a photograph of their—now dead—main countdown clock with the following text:"We can't wait to use this again." I imagine all their employees looking at it every day and tearing up. I know I would. If that's not sad, I don't know what is.
The last launch was the space shuttle Atlantis, on July 8, 2011. It's OK, NASA. The countdowns will resume soon. Until then, we can watch this again and again.
