Space Station, meet the Dragon

In another success for the Falcon 9 launcher and Dragon capsule, a second private resupply mission has docked to the International Space Station.  After a day's delay caused by thruster problems (a stuck valve or blocked line kept the spacecraft from using all its maneuvering/positioning thrusters), the Dragon  has made its docking. The mission was a triumph for the Falcon 9, which, on its last mission, had accomplished its main objective but had one of its 9 engines pretty much come apart.  Congrats to SpaceX!
