We realize there's only so much time one can spend in a day watching new trailers, viral video clips, and shaky cell phone footage of people arguing on live television. This is why every day The Atlantic Wire highlights the videos that truly earn your five minutes (or less) of attention. Today: asteroid mining, explained, The Walking Dead the video game is like a more prolific version of the series, and Phillip Humber was very excited to meet David Letterman.

James Cameron, Google chairman Eric Schmidt and former Microsoft chief software engineer Charles Simonyi are some of the wealthy, scientific-ish types investing in Planetary Resources, a new company dedicated to mining near-earth asteroids for precious metals and minerals, and probably unwittingly bringing a bad alien back to earth somehow. We kid about the alien, but we wonder if asteroid mining is the world's -- sorry, the galaxy's  -- safest bet. It would seem to combine the unpredictability and danger of regular mining with the added obstacle of being in space. We'll find out soon enough, since the company vows to launch its first space shuttle next year. [via Planetary Resources]

The Walking Dead is getting the blood-spattered video game adaptation treatment, and the end product looks significantly better than that Ron Paul game where you have to beat up a cloud with a moustache. It also virtually guarantees that the number of hours we've spent watching Walking Dead promos and spin-off properties will continue to dwarf the number of hours we've spent watching the actual Walking Dead. We have more memories of Frank Darabont's murky exit as show runner than the flesh-eating monsters he brought into our living room on basic cable.  [via DailyDead]

It is always pleasant when wide-eyed, newly-minted sports icons read the "Top Ten" list on Late Night. So much enthusiasm! Chicago White Sox pitcher Phillip Humber, he of the perfect game that shouldn't have been a perfect game, was no exception. We also enjoyed  how Humber raved to the Chicago-Tribune about what an honor it was to meet Letterman. He also called him "a very nice man" and a "great communicator," which we also would probably say if we appeared on Late Night and threw a perfect game in the same 96-hour timeframe.

Finally, in the long-but-worth-it department, here's Conan O'Brien doing a very interesting, not-too-on Q&A session with students at the University of California-San Diego. That's our favorite Conan. [Laughspin]
