On now. I came in late.
Heard: Sensors exonerated. Problem in wiring. No promises on launch date. Q&A started.
Circuits open up. Some for minutes; some for hours. It's temperature related; doesn't happen unless chilled. A particular connector is being asked about. A socket connector inside tank is hard to get to. Would take more than a week. Pleased the particular connector has been indicated.
Sounds like it's an interface at the tank external surface, with wires leading from sensors to socket, with a plug that is inserted into the tank socket for analysis of signals. Sounds like problem may still be the plug into the socket or the socket external parts (both easy to get to) or the wires' attachment to socket, inside tank (which would be harder to get at). I'm unsure; just trying to piece it together.
It's a "feed-through" connector. Engineers now know what to look at. It's a relief to have that. Will talk about launch commit another day.
Will follow trail. Solve problem. Then fly. When it's fixed. No date offered. Again.
Time-domain pulse reflectometer helped nail it. (A little like sonar pings, to determine where a reflection is coming from.) Resolution not enough to say inside or outside the connector, just thereabouts.
