It’s the fiftieth anniversary of Sputnik, the beginning of the Space Age as we know it. Alan Boyle’s Cosmic Log has some reading material for you (hat tip: Rand Simberg), and Middledawn has some visuals appropriate to the day.
(On a possibly-related subject: What do we have to do to get In the Shadow of the Moon booked here? Do we not have enough screens for Good Luck Chuck, or what?)
Title, of course, poached from John Magee.
