Topics: New Horizons, mission status

They seemed to be discussing some kind of anomaly with one of the pre-launch tests on the launch vehicle, but I didn't catch exactly what it was; something was "not exactly as planned." But there are all kinds of other people checking in with "test complete" comments, and the countdown seems to be progressing on schedule. Launch time remains on schedule for 10:24. Here's the clarification: the issue is with the "fill and drain" valve on the Atlas LOX tank. There was a concern that it may not open or close or required, so they need to verify that it will close when topping ends.

Winds remain steady at 24 knots, with gusts up to the acceptable limit of 33 knots.
