No use to have it flying yet, thing hasn't even launched

It may take the UAV too much time to get to the landing area to wait for launch.

Need to pick up count in 24.5 minutes. Still waiting on word on the anomaly resolution.

The swing arm is at the bottom of the LOX tanks. LH2 feed is at the base of the pad, IIRC.

Base. The CBC interfaces near the ground are VERY similar to the Shuttle TSMs.

Skies look clear.

Thanks mheney and Antares.

Splashdown is 600 miles offshore. UAV can loiter a long time, but it needs to get on station.

Purely speculation on my part, but when there is talk about pressurizing tanks to assist with valve issues, foreign contaminants spring to mind. It tells you immediately that the concern does not rest with the instrumentation.

Vented gas color has changed from gray to black.

Shadow...

Standing by on whether the valve cycle problem has been resolved.

Are the fill and drain valves located at the base or the middle of the vehicle, where the swing arm is taking away the LH2 from the CBCs?

At the base near the TSM's. The swing arm is only for GH2 vent

Despite the window remaining time, would not the launch procedure need to pick up again at 35 min after the hour?

Jim · « **Reply #375 on:** 12/04/2014 01:23 pm »

not looking good

info via contractor: scrub call in work. Team working last resort option to unstick fill and drain valves.

Antares · « **Reply #377 on:** 12/04/2014 01:24 pm »

I'd set up for the end of the window and give it a shot.

Chris Bergin · « **Reply #378 on:** 12/04/2014 01:24 pm »

Sounds like they are trying one last step to resolve.

Steven Pietrobon · « **Reply #379 on:** 12/04/2014 01:25 pm »

Reduce fast fill. Pressure at 35 and then cycling. Did not have success on last test.

20 minutes left in window.
