Apparently flawless launch and orbital insertion just now.
Launch was done within a 1 second launch window. Dragon will deliver cargo to the International Space Station again. The first stage will attempt a vertical landing in the ocean with the Grasshopper mod, which would be huge. Elon gave a low chance of succeeding on this first attempt. But as he said elsewhere, "If something's important enough, you should try, even if the probable outcome is failure."
