SpaceX Landing attempt #2 – Another awesome explosion

As the capsule separates from the first stage rocket, the second stage booster takes over and sends Dragon into orbit around the Earth to rendezvous with it’s target a few hours from now.  At this point the mission is a complete success from NASA’s perspective, but to Elon Musk and the rest of the SpaceX team, the real challenge is just beginning.  They have to land that first stage rocket on a 300 x 170 foot barge in the vast ocean, or risk losing millions of dollars in their investment.
