The Business and Future of Space Exploration

Hosted by
From personal satellites to tourism, space travel is going private.  With NASA no longer sending shuttles up, what does that mean for exploration and scientific research? Can private companies lead the way to this final frontier? Also, Attorney General Eric Holder is taking on Texas and its voting laws.
