GRAIL is trying for launch today at 8:29 PDT / 12:29 UT or 9:08 PDT / 6:08 UT., and here I am at 5:00 am my time ready to watch. As before, I'm watching the feed through Spaceflight Now's GRAIL mission status center. Another good place to watch will likely be JPL's Ustream channel. Here's the new launch timeline. Although the liftoff times are correct, the actual timelines after that may vary by a few seconds, especially after the first firing of the second stage. Every day that the launch is delayed, the two launch windows move earlier in the day by about four minutes.
