NASA deemed successful a month-long test of image transfers to and from the Epoxi space probe, currently 20 million miles away somewhere near Mars. Alleged Internet inventor Vint Cerf helped NASA design the enabling technology, known as Delay Tolerant Networking, a decade ago. (I know: What does that guy do now?)For NASA, DTN means not having to send exact signals at an exact time to a spacecraft. A missed connection can be tried again until it succeeds. If you've been around long enough, it sounds conspicuously like USENET back in the acoustic-modem days. NASA touts the technology's usefulness in communicating with deep-space robotic craft. Who are they kidding? The real win is that when human beings inevitably go back into space, they'll be able to keep up on Earthbound puppycams. (Illustration by NASA)
