Space X Landing

Congrats to SpaceX for sticking the landing on their launch.  Now that they can bring their stage back, they'll have to show if they can one-up NASA by actually saving money doing it.  All of the analysis I've seen shows that reusability for launch vehicles tends to be a very marginal business case if the launch rates are low.  Hopefully the market is strong enough to make this all work out, it's very cool technology!
