Today's #OA7 launch will be George Diller's final call. His contributions will carry on with the likes of King & Navias. #ThankYouGeorge 🚀

As seen from the static shot, liquid oxygen is now beginning to vent from the CCB as the tanks continue to be filled.

As reported by ChrisGebhardt, there's a CCB sensor that is not working right now.

Whether this results in a delay or not, we'll find out soon.

Atlas LOX depletion sensors are getting unusual spikes now.   IFS confirms this is "nominal".  Teams will "keep an eye on this."

Static shots are over.

Just switched to the pre-coverage "wait" screen.

Chilldown pipe "looks like there's more LOX coming out of vent than normal". - FD loop.

Prop-1 reports LOX leakage out of chilldown line.  Another anomaly team has been convened to provide a recommendation.

Live from Cape Canaveral Air Force Station, NASA TV is proud to present coverage of the launch of AV-070 carrying the 7th CRS Cygnus spacecraft to the International Space Station.

Today's PAO is, for the last time, George Diller, whose launch log spans from May 1989 to today.
