Alt-week 6.22.13: The LRO's fourth moon-year, a 3D brain and alien telegrams (video)

The moon is far from old hat. In fact, after exactly four years on the job, the Lunar Reconnaissance Orbiter (LRO) is just scratching its jagged surface. The dearth of info on our celestial neighbor isn't stopping us from trying to send personal space messages to a far-flung star system, though. Why? Blame it on our huge brains, which we've now mapped in detailed 3D. Yes, this is alt-week.
