The Atlas V launch carrying the WorldView 4 commercial imaging satellite scheduled from Vandenberg has been scrubbed again. It scrubbed Friday due to an apparent liquid hydrogen leak, and today was scrubbed because of a wildfire south of the pad. The wildfire doesn’t present any immediate danger to the launch complex, but firefighters can’t fight it while they’re on standby for a launch. Fighting the fire is more important, of course, so ULA is standing down for today, to allow the firefighting crews to tackle the blaze. The range unfortunately is no longer available after today, so they will have to wait for an opportunity on Monday, September 26.
