Verdict on asteroid mining: 'No bull!'

Mining asteroids for water and precious metals may sound like a sci-fi boondoggle, especially the way Jon Stewart described it Wednesday night on "The Daily Show" on Comedy Central. When Planetary Resources co-founder Eric Anderson says water would be worth $20,000 to $50,000 a pound in space, Stewart quips, "Who amongst us wouldn't pay $50,000 for a pound of space water ... at the space convenience store?" To cut through the orbital debris, Stewart brought astrophysicist Neil deGrasse Tyson on stage to weigh in during a segment called "Bulls#*t or No Bulls#*t." In just one minute, Tyson rendered his decision — while solving a Rubik's Cube puzzle and ribbing Stewart about the reverse-rotating Earth in his show's opening credits. Watch how it went down in the video clip above, and get the straight story from MSNBC's Dylan Ratigan in the clip below.

X Prize creator Peter Diamandis and Space Adventures' Eric Anderson launched a new company with lofty ambitions: mining asteroids. MSNBC's Dylan Ratigan reports.
