I know it's not modern tech, and it was designed and built before some of you were born, but I still think that the Voyager probes (along with the Pioneer probes) are pretty awesome and so this long distance reboot deserves coverage:
Earlier this month, engineers suspended Voyager 2's science measurements because of an unexpected problem in its communications stream. A glitch in the flight data system, which formats information for radioing to Earth, was believed to be the problem. Engineers were able to replicate the glitch in a computer lab, showing that a single bit flip was responsible. NASA plans to reset Voyager's memory tomorrow.
The spacecraft is so far away it takes nearly 13 hours for a radio signal from Earth, traveling at the speed of light, to reach it, and another 13 hours to receive a response.
That's a pretty cool reboot!
