    In this story I felt a vast weariness over the space program, which had thrilled us so at the start -- especially the first lunar landing -- and then had been forgotten and virtually shut down, a relic of history. I wondered, if time-travel became a 'program', would it suffer the same fate? Or was there an even worse possibility latent in it, within the very nature of the paradoxes of time-travel? {PKD}
